PREFACE. This book is the result of an effort to put into the plain language of the farm the facts which scientists have worked out in the laboratory, and which practical experience has proved to be applicable to the every day work of the farm. It is written for men who know nothing of chemistry, but who are anxious to learn something of the chemical combinations that are of value in the feeding of crops, and the best way to use them in the permanent improvement of their soil. For men who know nothing of the mysteries of plant life, but who are anxious to learn how plants live, grow and perform all their work in soil and air, so that they may be better able to comprehend their needs, and supply them in a rational manner. While endeavoring to make the book scientifically accurate in all its statements I have tried to avoid all pedantry, but to make the whole so plain that the “way- faring man, though a fool, need not err.” I have undertaken the work with a good deal of misgiving as to what should be its exact position on some of the problems in nature as yet not fully solved, and about which there is much yet to be learned by the wisest minds. When such problems are attempted, I will candidly say that I do not as yet fully comprehend the processes involved, I will give the results so far as they are known. The acquirement of nitrogen by leguminous plants is one of the problems that has not yet been fully worked out, and while we know that they do get the nitrogen through the agency of minute organisms that live with them on their roots, the exact process by which these microscopic forms get the nitrogen is not yet fully understood. But for our purpose it is enough to know that they do get it and store it in the roots and soil for the future crop. N. C. College of A. & M. A,, Raleigh, N. C.

INTRODUCTION. The only excuse I have to offer for the manner in which this book presents the subject of crop growing and crop feeding, is the fact that there is so much of ignorance, even among men nominally educated, in regard to the vital processes in plant life. I meet men daily, who have taken college degrees and are in professional life, who still think that the sap rises in the trees in the spring and runs down in the fall; that is about all they know of plant life, and even that little is not true. They have never studied plant life in an intelligent manner, for in all of the old college curriculums botany has been rigorously ignored, or even if attempted, it was only a little spring time study and a brief effort to learn the scientific names by which the plants are called; the main effort was merely to do this, and the result was that the student knew no more about the wonderful life of the plants around him than he did before. Hence educated men, or rather men crammed with the information of the books, fall into all sorts of errors and believe all sorts of old wives’ fables about plants. A very intelligent gentleman who is interested in some phosphatic rock mines in this State, told me once that the rock they mined was more soluble than ordinary phosphatic rock because of the heavy forest growth above the deposit, for the sap running out from the roots of the trees in the fall had a solvent effect on the rock below. This man has traveled all over Europe and America, and has a large fund of general infor- mation,and no argument I could use would convince him that no sap runs from the trees in the fall. Late one fall a few years ago a reader of one of our city papers wrote an inquiry to the editor, saying that he had noticed that just before a rain the springs and brooks had swelled, and he wanted to know the reason. The editor, a college bred man, told him that the explanation was perfectly simple, as at that season the sap was running out of the tree roots and raised the springs. He never seemed to think of the real reason, the release of atmospheric pressure just before a rain. I wrote to the paper and told him that there was no such thing as sap running out of the roots of the trees, and entered into some explanation of the processes of plant life. It was amusing after my letter was published, to note the surprise with which it was received. Educated men stopped me on the street and asked if it was really true that the sap does not run out of the roots, and that all plants get the larger part of their fabric from the air and not from the soil. (11) 12 INTRODUCTION. This same general ignorance in regard to plant life is the cause of so many otherwise intelligent men believing that one plant can be suddenly transformed into an entirely different one. That wheat will change to chess or cheat. Men who have studied the life history of vegetation know the utter absurdity of this notion, but it is so firmly fixed in the minds of many intelligent men that it is perfectly useless to argue with them. They have never been taught accuracy of observation in their youth, and hence jump to conclusions that are not warranted by the facts. Some months ago a farmer iin this State wrote me a letter, asking if there was any premium offered by the Agricultural Department of the State for the positive proof that wheat would turn to cheat. I answered that there was no such offer, and I knew there was no such proof. A friend of mine, a leading lawyer of the writer’s neighborhood, then wrote to me that I had treated his friend rather curtly, for he knew that he had the positive proof, and he would send it to me. Accordingly a few days after I received a package containing a well grown plant of cheat with numerous wheat grains adhering to the tips of the rootlets. I wrote to the lawyer that if this was what he called proof, he would have to learn to sift evidence better or his reputation as a lawyer would suffer. The fact that dead wheat grains were attached to the feeding tips of the rootlets of the cheat, was simply proof that the wheat decayed and the roots of the cheat found the grains and were feeding on them. If the cheat had really germinated from the wheat, the grains would never have been found on the place where the absorptive root hairs were foraging for food, but would have been right up where they started from, and that what he regarded as positive proof of the transformation of wheat into cheat was, on the other hand, a positive proof that no such change had taken place, for the roots were simply seeking food, and the weather con- ditions that killed the wheat were just the kind that were favorable to the development of the hardy cheat, which never winter kills. It is with the hope that a study in a simple manner of some of the processes of plant life will help to banish superstitions, and will be the means of some of our readers getting a better understanding of the reasons that underlie the culture of our crops, and the sup- plying of them with food. We have made the effort to avoid, as far as possible, language that might confuse the unlearned, and to clothe facts in the every day language of the farm so far as possible. It will be noticed that we state that 95 per cent. or more of every plant comes from the air, and not from the soil, and we endeavor to explain how the plant gets the material from the air. But to see in a practical way how much of a plant comes from the air, take a good sized corn stalk and weigh it. Now cut it up and dry it thoroughly. Not merely air-dry, but dry it as a chemist would dry it in his dry bath. Now weigh it again, and you find that it contained a great deal of water. Now burn it carefully and completely, till you have only white ashes left. You will find that these weigh but a trifle as compared with the great corn plant. And yet that little handful of ashes contains all the plant got from the soil except the nitrogen, and that the soil originally got from the air. The mineral matters, or ash elements, are what you have left in the ashes. The rest was carbon and water, and it has gone off in the shape in which the plant originally got it, as carbonic acid, to feed other plants and make other structures, for there is no destruction in nature. The same old materials are being used over and over INTRODUCTION. 13 again, perpetually building up new forms. In regard to the nature of commercial fertilizers, there is a general notion among farmers that they are mere stimulants, and that while they can be used to increase crops, their final effect is to exhaust the soil. The injudicious way in which commercial fertilizers have been used in the Eastern Middle States, and in the Southern States, has led to this opinion. Used as they have been in the past by the cotton and tobacco growers of the South, they have been a curse to the country, and have led to poverty of soil and poverty to the farmer. But this is not the fault of the commercial fertilizer, for well prepared fer- tilizers are simply plant food, such as we find in any manure; and if properly used for the improvement of the soil, they can be made the means of restoring and maintaining the fertility of our lands more efficiently and cheaply than in any other manner. The only classes of substances used as applications to the soil to which the term stimulant can be properly applied are lime and plaster. These are used not so much for their value as plant food, but for their effects in ren- dering other matters, notably potash, available in the soil. They thus stimulate the soil to give up to plants matters it already has, and thus gradually tend to the exhaustion of these things if carelessly used, with the notion that lime and plaster will make land rich because we see a good effect from their application. There are extensive districts in the North, where once the farmers got large crops from the use of plaster alone, and imagining that plaster was all they needed, they kept on in its application, and now find that there is nothing more for the plaster to give them and are compelled to use commercial fertilizers liberally. Had they known more of the real work the plaster was doing for them they could have avoided the gradual exhaustion of the mineral elements in their soil. But there are some writers who would persuade the farmer that in the use of com- mercial fertilizers alone they have all that is needed, and that land can be kept perennially fertile simply by giving every crop a liberal application of a complete fertilizer. They beg us, when we urge the farmer to adopt a good rotation of crops in which the legumes are brought frequently to accumulate humus in the soil, to “give humus a rest,” insisting that humus is not plant food, and that crops can be grown as well without it as with it. It may be that in a season of very favorable weather and abundance of moisture in the soil, the commercial fertilizers will have their best effects, even if there is no humus or vegetable decay present. But in a season like the one we have just passed through, we have found in late October, in a soil deficient in humus, all the fertilizer applied in the furrow, as dry as it was when applied. Not two hundred feet away was land in which the humus content was much greater, and here the plants had gotten the dissolved plant food, because of the superior mosture-retaining nature of the decayed vegetable matter. Therefore, even if this decay furnished us no nitrogen, it would still be valuable for its mechanical effects in making the soil mellow, and in its power of retaining moisture for the plants. What we try to impress upon our readers in this book, above all else, is the fact that the true use of the commercial fertilizer is the main- tenance and increase of the fertility and productiveness of the soil, and not so much for the immediate returns in sale crops. True farming does not consist in the dosing of the soil for every crop with a prescription some land doctor advises as a specific for that crop, but in so using these valuable plant foods in the 14 INTRODUCTION. improvement of the soil that there will be no need in any of our ordinary farm cropping for the use of what is called a complete fertilizer at any time, and seldom any need for an application directly to the sale crop. Used in this way, there is no doubt that the fertility of the soil can be restored and maintained more cheaply and more rapidly by the use of commercial fertilizers than in any other way, though no farmer should wholly ignore the foundation of all rational farm improvement, the keeping and feeding of live stock.in the best manner, and the making and saving in the most careful manner all the domestic manures. The deplorable condition of much of the cotton land in the ‘South is due, not only to the injudicious use of commercial fertilizers as a means of getting sale crops, but to the entire abandonment of stock feeding by the cotton farmers. The annual cultivation of the soil in the one clean cultivated crop has used up the humus and none goes there, because there are no animals fed to make manure and no renovat- ing crops between the cotton crops, and when a dry season comes, the fertilizers applied are not dissolved and the crops are poor. The season of 1900 was remark- able as the hottest and dryest on record in the South Atlantic States, and the lands without fertilizer did as well or better than those directly fertilized. But recently, meeting Eble whom I knew was farming in a short rotation with legumes, I asked him about his cotton crop. “I expected to get 40 bales on 35 acres. The drought has affected me some, and I will have hardly more than 35 bales.” All around this man’s farm there are those who will hardly get a bale on five acres, and they spent more for fertilizers on their crop than he did, who gets a bale permacre. It is, therefore, with the earnest hope that we can induce farmers North and South, to understand the true use of commercial fertilizers that this book has been prepared. We have written it from the standpoint of the practical farmer, and have prepared it for practical farmers. While living in the South, a native of the South, and striving with all my energy to aid in the building up of the agricultural and horticultural interests of the southern cultivators of the soil, the writer has had a wide experience in the growing of plants and crops in various sections, and has traveled and studied the practices of growers in all parts of the country. He therefore feels that he is prepared : help farmers in various sections, and to contribute something, at least, to the general advancement. The great interest that has been awakened in regard to agricultural education is well shown by the great increase of books on agricultural topics. Formerly the effort was to treat of the whole subject of agri- culture and farm economy in a single small volume, and our libraries still contain some of those little books. In the organization of our Colleges of Agriculture and Mechanic Arts the greatest difficulty that beset the faculty in these institutions was the total absence of books on agriculture and horticulture that could be used as text books with the college classes. The result was that every professor was compelled to prepare his own lectures and to conduct the instruction along lines devised from time to time to meet the emergency. Out of this work there have grown up books in which various parts of scientific cropping are treated, and there is no longer any effort made to combine in one small volume all the matters that relate to cropping, stock breeding and feeding, farm drainage and soil manipula- tion; but the soil and its treatment and cropping have come to be considered as something separate and distinct from the animal husbandry of the farm. While INTRODUCTION. 15 in a work of this kind methods of soil preparation and culture are of necessity treated, to some extent, the chief aim of the book will be to make plain so far as has been ascertained, the methods of supplying the manurial needs of crops, and especially to endeavor to do something towards encouraging a more judicious use of the commercial fertilizers than is common among farmers. Few northern farmers fully realize to what extent the southern farmer has come to rely upon commercial fertilizers for every crop he plants. And it is important that in the interest that is now being taken in the Central West in the use of commercial fertilizers, that the farmers be protected from making the mistakes that have proved disastrous to the southern farmer, and that they should be taught in the beginning of their use of these fertilizers, where and how they may be made profitable, and how to avoid the dangers of soil wasting that have followed hard upon the use of commercial fertilizers in the cotton states. The poorest farmers and the best farmers use commercial fertilizers. The first-class dribbles them in small quantity under his sale crop, solely for the purpose of getting a little more to sell; the second class uses them in a far more liberal manner for the pur- pose of building up the soil and the development of its natural capacity. The first class of farmers simply use enough to add a little to what the land would do unaided, and thus get what the soil would do and all that the fertilizer did, and the result is that the soil is in a worse condition by reason of the application; and it is no wonder that the men who use these forms of plant food in this way have come to the conclusion that they are only stimulants. The greatest educational influence of late years among farmers who have passed the years when they could have attended a college, has been the Farmers’ Institutes. When these Institutes were first inaugaurated farmers as a class knew little about the chemistry of the fertilizers they used, and regarded that the best which smelled the worst. Since the Institutes and the Grange have been getting in their work there has been a wonderful change in this respect, and the farmer who does not know something about the chemical composition of the fertilizers he uses, and the nature of the elements entering into them, is as rare as one who did know these things was at one time. These educational influences have also brought about a change in other respects. Farmers, as a class, have now a greater respect for what they formerly ridiculed as “book farming,’ and today it is only the grossly ignorant among the farmers who fail to realize what scientific study and investi- gation have done for the farmer. Another educational influence that has been brought to bear upon the farmer is the Agricultural Experiment Station. The whole modern system of spraying for the prevention of fungous diseases in plants and to ward off the attacks of noxious insects, has been brought about through the work of the Experiment Stations, and on no subject of interest to the farmer have the Stations devoted more attention than to the study of the various forms of plant food sold as fertilizers, their composition and value. Before the inauguration of these Stations the farmer was at the mercy of the compounder of fertilizers, and had no means for ascertaining their real value. With the in- auguration of the Experiment Stations and their analyses of these mixtures came the passage of stricter laws regulating the sale of fertilizers and protecting not only the farmer, but the honest fertilizer manufacturer, from the frauds that were formerly so common. The result of all these influences is that farmers who 16 INTRODUCTION. never had the advantages of a scientific training have been taught to understand what is necessary in a good fertilizer, and are rapidly learning that they can make these mixtures themselves as easily as to buy them ready mixed, and can save money in so doing. Then, too, the result of the publication of the analyses of commercial fertilizers has had the effect of driving from the market inferior articles and of improving the general standard of the factory-made fertilizers, and in States having a good and well enforced fertilizer control, the farmers are now protected from rogues, and the honest manufacturers are not compelled to compete with them. We have urged the home mixing of fertilizers upon our farmers, not from any antagonism to the manufacturers of fertilizers, but because we know that in the thoughtless purchase of ready mixed articles, growers are continually buying what they do not need to buy, and getting mixtures poorly adapted to their soil and crops, though they may be manufactured with perfect accuracy and honesty. No one mixture will suit all parts of the same farm, or all the crops grown upon it, and the farmer will thus be compelled to buy various brands in order to get what he needs. But if he buys the materials and mixes them to suit his soils and crops he can buy the whole in larger quantity and at a lower price. The fact has more than once been demonstrated at the Experi- ment Stations, that one may buy at retail the various materials that enter into a commercial fertilizer, and save money from the price he would have to pay for factory mixed goods. This book, being written by a farmer, for the benefit of farmers, will advocate what its author believes to be the best interest of the farmer. without regard to what others may think of what we write. It will, as I have said, treat the subject of cropping and feeding crops from the standpoint of the practical farmer in full sympathy with the work of scientific investigation. Having been more or less connected with the practical carrying out of Station investigations in agriculture and horticulture, since the foundation of the Experi- ment Stations, the author of this book has had exceptional opportunities for study and observation; and these apportunities, added to his long experience as a practical cultivator of the soil in farm, garden and greenhouse, enables him to write with some confidence for the benefit of those who, like him, are endeavoring to win bread from the soil. The original design was simply to make the work a reference book on the use of fertilizers for the general farmer. But it is difficult to write of the use of fertilizers without going somewhat into details of cultural methods; and then, too, the market gardener, the orchardist, the florist and the winter forcer of products under glass, are all interested in the use of commercial fertilizers. Hence the idea of the work has grown so as to include some of the work of each, and our hope is that all will find it a valuable book of reference. So far as the garden crops and the work under glass are concerned, special attention is paid to the needs of the market gardeners of the South Atlantie and Southern States, since the work of the gardener in the North will be more fully discussed by those actually engaged in the business there. CHAPTER I. THE AIR. All plants and animals pass their lives at the bottom of the great ocean of air that surrounds the earth. From this air plants derive by far the greater part of their substance. Pure air is a mixture of two invisible gases, nitrogen and oxygen. The nitrogen is for the purpose of diluting the oxygen so that animals can breathe it. But the two gases are not combined with each other. ‘The nitrogen is called free nitrogen because it is perfectly free from any combination with other elements, but in order that plants can use it it must become so combined. But of this later. We have said that plants derive the greater part of their substance from the air. In fact about 95 per cent. of every plant comes from the air, or to speak more correctly, from matters that exist as an impurity in the air. For while pure air is composed of the two gases mentioned, there are always more or less of other gases in it, not as essential parts of the air for animal life, but as impurities and detri- mental to animals. But with plants the case is very different. One of the impurities in the air is the gas called, commonly, carbonic acid, and which is known to the chemist as carbon-di-oxide; that is, it consists of two parts of oxygen associated and combined with one part of carbon. This carbon- -di-oxide is the gas that accumulates in old wells and mines and makes what is called choke damp, so deadly to animal life. But there is always a minute portion of it in the air everywhere, and while an excess is damaging to animal life a small portion is essential to the welfare of all plants that make green leaves. HOW GREEN LEAVED PLANTS GET FOOD FROM THE AIR. All growth in plants and animals alike, is made by the increase in number and the development of certain microscopic boxes known as cells. A very thin cross section of a piece of the pith of the elder will show the primary (17) 18—Crop GROWING AND Crop FEEDING structure of plant cells under a glass of small magnifying power. ‘There are many plants of minute size existing in water that, during all their lives, con- sist of but a single box or cell. Then advancing in complexity we find these cells strung together in threads, then in flat surfaces in a single layer, and finally arranged in numerous forms circling around the stem of the plant to make up the structure. We are so accustomed to look upon a tree as an individual existence that it is hard to realize that it is really a great com- munity of individuals, each doing its work in the way it was set out to do in the beginning and never making any mistake about it. It is hard to realize too, that the framework of the great oak is a lifeless thing, around which life circles in a myriad of forms, while it has entirely abandoned its finished work, and that the central heart wood takes no part whatever in the vital functions of the tree, but is merely the mechanical support of the army of builders which, year after year, add thickness to its stem and wider spread to its branches. This heart may entirely decay and the tree become hollow, and the life still continue to circle around it. Hence it is important to know more of the structure and functions of plants in order to fully understand their needs. We have said that all growth is made by the multiplication of these little box-like cells. The tree grows like a building, in which brick after brick is placed in the walls. But in the case of the plant the brick maker and the mason live inside the brick. The walls of the cells contain no life, but are the result of the vital forces contained within them. Every plant cell in its growing state is filled with the substance that carries life with it. This substance has been given the name of protoplasm, or the first thing formed. It is a clear semi-fluid substance, partly granular and partly transparent, and uniform in its appearance. ‘This substance, resembling the white of an egg more than anything else, does all the work of the plant, and it is what in the composition of the plant is called by chemists the albumenoid or protein part. It is itself entirely formless, and yet this formless substance controls the shape of the cell that encloses it, and makes the wonderful variety of forms of cells that we find in the plant by the aid of our microscopes, and little by little builds up the form of the plant, always with an unerring accuracy, so that the final result is such that we recognize the plant as belonging to a certain genus and species, though it may be, and probably is, in some minor points unlike every other plant, even of the same species. But as to the essential features, the protoplasm never makes any mistake. The oak may grow beside the pine, and their roots interlock and feed upon the same substances in the-soil, while their tops are bathed in the same sunlight. But the oak never by any chance makes a pine cell, nor the pine an oak cell ; = THE Atr—19 though no one can discern any difference in the living matter of the two. Each follows the laws of its inheritance, and obeys the order set out for it in creation. I have said that this living matter inside the plant cells is partly of a granular nature. Some of these grains are colored green, and thus give us the green color of vegetation. This green color is a very important matter, for without it there could be no growth. We may put a plant in darkness and blanch the leaves white, and then examine the grains under the micro- scope and we find that they are still there, but the green color is gone, and the plant stops growing. It is evident then that the green is of importance to the growth of the plant. It is, in fact, the substance that enables the plant to get the food it needs from the carbon-di-oxide in the air. Every leaf has on its surface a mutitude of small valves, opening and closing like a pair of lips, and they are really the mouths through which it takes in food. These mouths are far more plentiful on the under sides of leaves than on the upper, and in some plants there are none at all in the upper surface. ‘The interior of the leaf is made up of a loose aggregation of cells containing the green granules. The mouths open in among the spaces be- tween these loosely arranged cells, and thus bring the air to the interior of the leaf. When the sun is shining, and at no other time, these mouths in the leaf are wide open. The air enters the leaf laden with the carbon-di-oxide. If the temperature around is proper for the growth of that particular plant, the green matter at once decomposes the carbon-di-oxide, separating the car- bon from the oxygen. The oxygen is then thrown off to purify the air, and the carbon is retained by the plant. We do not know that this identical oxygen is that which is thrown off, but we do know from experiment that the same amount of oxygen is thrown off as was combined with the carbon. Now in the wonderful laboratory of the green leaf, begins the work of the living matter. From the roots water has been brought up to the leaves, in which is dissolved the various forms of plant food that come from the soil. As it comes from the roots it is merely water with plant food dissolved in it. With this water, and the carbon that has been gotten from the air through the leaf mouths, the living matter goes to work to prepare food for its own suste- nance, and to make the materials out of which it builds its cell walls, and thickens their woody structure. The first thing formed from the carbon, hydrogen and oxygen, is probably some form of sugar for the immediate use of the plant. But the living matter works rapidly, and makes more material than it can use at once, either for food or building walls, and hence it has to store the reserve material. This reserve material is the first thing we can dis- cover in the leaf, and it is starch. When starch is made in the leaf it is soon 20—Crop GROWING AND Crop FEEDING carried away and stored for future use, unless at once needed to build walls with. It is stored in roots, in underground tubers like the Irish potato, and in stems generally, and in seeds. The surplus over what the plant needs for its existence, forms what animals consume as food. In some seeds, the starch is further transformed into oil for preservation. Now neither starch nor oil are direct plant food, but they are stored in the seed for the future use of the germinating plant, as they will keep unchanged, while sugar, the food, will not keep. But when a seed germinates another wonderful change takes place. A fermentive principle is formed, which has the power to transform the oil back into starch, and from starch into glucose, or grape sugar, which can be used directly by the living matter as food, and as material for building up structure, until the green leaves are formed and the roots begin to absorb matter from the soil. During the time the seed has been dry, the living matter has simply been dormant, waiting for the coming of water under a proper temperature with the oxygen of the air, to render it once more active. There is a great differ- ence in the length of time during which the living matter will retain its vitality in a dormant state. Some seeds lose their vitality as soon as they be- come completely air dry ; others will retain their vitality for a year, while still others will remain dormant for a number of years, and will grow as soon as the proper conditions of moisture , heat and air are present. Elsewhere will be found a table showing the length of time different seeds are good. HOW PLANTS GET FOOD FROM THE SOIL. Put several layers of damp blotting paper in a glass jar or tumbler, and on it place several beans, and then cover with a piece of glass, so as to retain moisture. In a few days the beans will germinate, and begin to throw out long white roots. Now examine these roots. You will find that the extreme tip of the rootlet is of rather a conical shape and is smooth and naked, while a little back from the tip a magnifying glass of moderate power will show you that the sur- face of the root is covered with a thick coat of fine velvety hairs. These root hairs are the organs through which the plant absorbs water from the soil. Their extreme fineness precludes the possibility of anything being absorbed that is not in a state of complete solution, as all solid particles must of course, be strained out. The mineral food of the plant is dissolved in the soil water, and is sucked by the root hairs from the watery films that surround each particle of the soil. In order that they shall do this, it is essential that the THr AIR—21 particles of the soil shall be in a state of fine pulverization, whereby its power of retaining moisture is greatly increased. Prof. King, in his work on the soil, illustrated this in the following way: A marble, dipped in water, will retain around it a film of water. If it is broken in two there will be an increase of surface to hold a film of water, and if it is pulverized, there will be a marvellous increase in the number of particles, each having a film of water around it. These root hairs are produced on a short part of the rootlet just back of the tip as fast as the tip is projected into the soil, and as the root back of them grows older, and the cell walls thicken, the root hairs die off, and that part of the root remains simply as a conduit for the water the root hairs are gathering beyond. In this way, the root hairs are being continually formed in fresh soil and are foraging in new pastures. It should be easy then to understand. that where a little fertilizer or manure is placed only in the hill, the roots soon get beyond it, and the feeding organs, the root hairs, are hunting for food in poorer soil. But the root tip itself is one of the most admirably contrived parts of the whole plant. The extreme point of every rootlet is a little older than the part just behind it. In other words, the actual growing tip of the rootlet is a group of young forming cells under the protection of a root cap. At this growing point new cells are formed to continue the elongation of the root, and to add to the stricture of the root cap from beneath, so that the root cap is always being renewed from behind, as it is pushed through the soil by the elongation of the root behind it, and protects the young forming cells beneath it. It is easy to see that this is an admirable provision for the protection of the point of growth. In the older botanical works, it was stated that the ex- treme tips of the roots were what they called “spongioles,”-and it was supposed that the work of absorption was carried on by the “spongioles.” Having now- adays better microscopes, we have learned that there are no “spongioles” at all, but that the protecting root cap goes ever ahead of the advancing rootlet to search out the way, and to guide the root into fresh food. There seems to be a sort of dull sensitiveness in the root cap, by which it is in a measure en- abled to choose its way among the particles of the soil. The roots branch in an irregular sort of a manner, and not after the regularity of the branches above the ground, each branch coming out from the central core of the rootlet, and carrying with it a portion of the outer bark as its first root cap, and then the branches form root hairs just as the main rootlets do. The root hairs seem to have the power, by some sort of secretion, to attach themselves firmly to the particles of the soil and suck moisture from 22—Crop GROWING AND Crop FEEDING them. If you sprout a seed in sand, and when the roots have developed, take it carefully from the sand and gently wash the roots, you will find that the root hairs are covered with fine particles of the sand, closely adhering to them. This close adhesion of the root hairs enables them to absorb all the moisture that surrounds the soil particles as a film, and enables them to get an amount of moisture from an apparently dry soil, that is surprising to those who have not studied that matter closely. There is also evidence that the root hairs do to some extent, exert a solvent influence on matters in soil otherwise insoluble. THE COURSE OF THE SOIL WATER IN THE PLANT. There is a direct connection between the roots branching in the soil, with their myriad of absorbing hairs, and the leaves on the top of the plant. In our trees and woody plants, this course is through the youngest sap wood, and in herbaceous plants like corn, it is through the pithy soft tissue. Anyone who has observed a corn stalk, has seen that through the soft part of the stalk there are a multitude of threads. Observing a cross section of the corn stalk under the microscope, we see that these threads are really tubes, or elongated cells, with thickened walls, and in the growing state of the plant, the walls of these cells are always saturated. As the leaves branch off, some of these tubu- lar threads branch into the leaves and form the framework, or what we call the veins of the leaf. It is through these fibres that the sap water reaches the leaves, and it is in the leaf where all the wonderful changes are made by which new material for growth is formed. Then after the materia! for growth is made it is carried wherever there is call for material through the youngest cells of the growing bark, and all the material for growth of top and roots comes from the leaves. Twist a wire tightly around the stem of a growing plant, and you will see that the growth is coming downward from the leaves. The stem swells above the stricture, and if it is long continued the path for the ascending sap water is finally cut off, and the branch will perish, with a swollen base formed from the materials that were taken in from air and soil before the wire was placed there. There was an old notion that the sap goes up in the spring and down in the fall. The fact is, that there is no circulation in plants that can be com- pared with the circulation of the blood in animals. The sap that rises in the trees in the spring is simply sap water in which the food of a mineral nature for the plant and the nitrogen for the living matter is dissolved, and the only descent is that of the formed material for growth. THe Arr—23 This sap water, when it comes from the ground, is in a very dilute state; and another function of the valves or mouths in the leaves, is to evaporate water into the air, and in this way, to condense and concentrate the food brought from the soil. This evaporation is also one of the means by which the water is pumped up from below, and that there is a rapid evaporation from the leaves is evidenced when we cut off a leafy branch and note how quickly the leaves wilt when the supply is cut off. Wilting of the leaves is also one of nature’s methods of protecting the plant. During the hours of sunlight, and at no other time, the mouths in the leaves are open to take in carbonic acid. But if the heat is great and the soil is dry, the leaves will wilt, and this at once closes the pores or mouths, and checks the evaporation until the plant can recover a supply from below. CHAPTER II. THE GROWTH OF A SEED. The prime object of the plant’s existence is to prepare for the perpetuation of its kind. In some plants, the whole force of its vitality is expended in one season, in the production of a large crop of seed, in the growth of which the plant is exhausted, and it perishes after the seeds are formed. Such plants enduring but for a summer, we call annuals. There are others that spend the first year of their existence in the storing up in roots a great accumulation of food, which they exhaust the next season in the production of seed, and they, too, then perish. These are called biennials, or two year plants. Others store up growth of larger dimensions, year after year, and finally, when strong and well matured, give some of the accumulated vitality to the production of fruit and seed, and continue to do so for many years; some for hundreds of years, having a rather indefinite term of existence. These we call perennials, or plants living through a long series of years. Still another class accumulate during years of growth, long or short, a great store of food, and finally make the supreme effort of their lives in the production of a vast growth of flowers and fruit, and then perish. To this class belong the plants known as Century plants, the American Agaves and others. F The plants that farmers depend upon for crops are chiefly the annual and biennial classes. THE FLOWER. The flower of a plant is considered by botanists to be really a collection of leaves, changed in various ways to serve the purpose of reproduction. Every complete flower has two protecting coats; the outer one called the calyx is commonly green, but is sometimes brightly colored. The inner circle of transformed leaves is called the corolla, and its separate leaves are called petals , while those of the calyx are called sepals. The inner circles of leaves are still further transformed so as to make stamens and pistils. On the sta- (24) THE GROWTH OF A SEED—25 mens are borne certain cells that open by valves, and which contain the male element of the flower called the pollen. The central set of transformed leaves makes what is called the pistil or female organ of the flower. At the lower end of this grows the seed vessel, or ovary, containing the ovules, which are to be transformed into seeds. At the upper end of the pistil is a variously shaped organ known as the stigma, which is naked and for a while moist on the surface. The pollen, or male element, falls on this and swells and begins to grow into a tube of various lengths, according to the character of the flower. This pollen tube passes through the tissue of the pistil till it reaches the ovary, and there in a certain cell of the ovule it sets up a new growth of cells, that gradually take on the form of a miniature plantlet, and form what is called the embryo, or germ, of the seed. In this seed the plant then stores up starch or oil sufficient for its sustenance till in its germination it can make green leaves. It then rapidly parts with the water and the seed. be- comes ripe, and remains dormant until brought again under the influence of moisture, warmth and the oxygen of the air. A seed then is a living organism in which vitality is simply suspended for a time, and which contains all the elements of a future plant when placed under proper conditions for growth. If it has these conditions it will grow. If they or any one of them are absent it will remain dormant or perish. If the seed is buried so deeply that the oxygen of the air cannot properly affect it, though there may be moisture and heat, it will not grow. We see this fre- quently in the case of clover seeds deeply buried in the soil, which grow after they have again been turned up to the influence of the air. If moisture is absent, the living matter of the seed cannot swell and become active, and though there may be heat and oxygen enough, the seed cannot grow. ‘Then, too, there may be moisture and oxygen, but if the temperature is not right for that particular seed, it will not grow. This proper temperature varies with different seeds. All cultivators know that some seeds need more heat than others. The garden pea will germinate at a temperature but little above the freezing point, while Indian corn subjected to the same conditions will perish. It is essential then, to know something of the nature of the seeds we plant so that we may give them the proper conditions of growth. THE FRUIT. While the seed is the final, result of the plant’s effort at reproduction, the fruit is the ripened vessel or ovary which contains these seeds. The pea pod is the fruit of the pea plant, and is simply the ripened seed vessel. But there are some plants in which other parts are commonly known as the fruit. 26—Crop GROWING AND Crop FEEDING In the apple, the ripened seed. vessel, or core, is surrounded by the thickening calyx of the flower, which increases in size after the petals of the flower fall, and surround the fruit proper, which we call the core, and this thickened calyx is what we use as the fruit of the apple and pear and quince. In the strawberry, the end of the stem on which the fruits are borne, swells up and carries the collection of little fruits up, borne on its outer surface in little depressions. We call this edible part the fruit, while the botanist calls the seed vessels that contain the seeds, the true fruit. The edible part of the strawberry is merely the swollen receptacle which bore the flower. In our Indian corn, each grain that we call a seed is a separate fruit, the result of the ripening of the ovary of the pistil, which is the silk. For every grain on the cob is the result of a single female flower, and each grain has its own silk, and if each silk does not get pollen from the tassel, or male organ, there is no grain formed. Hence we can easily see why a single stalk of corn standing in a field seldom makes a perfect ear. In the field the great cloud of pollen that floats all around and covers the ground insures the fertili- zation or impregnation of every silk. The cereal grains then are ripened fruits and not mere seeds. In a state of nature the plant simply stores food enough to insure the growth of the plantlet for a while after germination. In cultivation the effort is to increase this store that it may be made use of by man for food for himself and domestic animals. Nature is content with mere reproduction ; we want something else. Hence to keep plants up to a greater production of useful material, it is necessary that we should accumulate the desirable qualities by constant selection of those that show the greater ten- dency to make what we want. Nature is perfectly content with a wild crab apple. It has all the power of reproduction, and is more hardy and vigorous than the highly developed apple, since it is the survival in the struggle with other plants of like character, while the plants we would choose have developed a certain desirable character for our use, but have in other respects gotten less able to survive in a struggle with wild plants. So we have paid attention to the accumulation of a desirable growth of the edible portion of the apple. and have bred it away from the original wild crab into something we want. But turn it back to the unaided forces of nature and it will soon revert to a form adapted to survive and the fruit will become less and less desirable to man. We find, then, that the more we refine a plant and fit it for our use the more it needs the fostering care of man, and the less able it is to take care of itself. The wild potato of Peru and Arizona makes small underground tubers, simply enough to keep a portion of the plant with buds and capable of grow- THE GrRowTH OF A SEED—27 ing again. We have bred the cultivated potato into the habit of storing larger quantities of starch in its under ground tubers, and this, too, has been brought about by a gradual accumulative selection of those that develop this habit to the greatest extent. Left to themselves, there is a constant tendency to revert into original and inferior forms. Our tomatoes are the result of long selection, starting with a cross of the smooth and hollow forms on the crooked and solid fleshed sorts, we have by accumulative selection gotten the knobby tomato inside the smooth skin of the hollow one, and we find yet that it is hard to keep it there, and the volun- teer plants that annually come up in the garden are apt to revert into one or the other of the original forms. CHAPTER 3. PLANT BREEDING. Many people imagine that the new and improved forms of garden and field plants that are brought out by our enterprising seedsmen are the result of some sort of magical hocus pocus of crossing or hybridizing, and think that by taking two plants that have characters we wish to combine we can, by crossing them, at once obtain the combined character we want. The fact is, that crossing simply gives us a starting point from which, by long and careful selection towards an ideal plant we may have in mind, we may finally reach a point near what we aimed at. The new varieties introduced by the seedsmen, when they are really new and valuable, are the result of long years of careful selection through which hereditary characters have been formed that may be expected to be permanent in the offspring. The writer once attempted the development of a variety of sugar corn that would have stamina enough for the Southern climate. As a starting point, a cross was made of the Leaming, a Western field corn of a yellow color, on the Mammoth sugar, a large eared, late sugar corn of a white color. The first result of the cross was to cut the plant loose from its inherited character, and the ears came sprinkled all over with white wrinkled grains, yellow wrinkled grains, white dent grains and yellow dent grains. We assumed that the yellow wrinkled grains were the ones that inherited the characters of both parents. Therefore we selected only these-for planting. The next season there was a larger pro- portion of grains that had this character, and they were produced on a plant - of a sturdy, yet short habit and just the style of plant we were aiming at. The process of selection was carried on year after. year in a location where the plants could not be affected by pollen from any other corn. But it required seven years of careful selection before we could establish the heredity that caused the plant uniformly to make yellow wrinkled grains all over the ears. (28) PLANT BREEDING—29 I mention this to show that the making of an improved variety of any plant that is reproduced from seed is nota sudden thing, but must be the result of long and patient effort. But it is an effort that any observant farmer can make for himself, and he can thereby increase the value of his crops to a very marked extent. There is no magic about it, but only the patient working towards an ideal well formed in mind to which we wish to attain. But in all plant breeding and improvement we must work for the char- acter of the whole plant and not for a single feature. In the colder sections of our country plant breeders who have undertaken the improvement of the Indian corn have been compelled to take earliness of ripening into account, and hence have developed a character that is not essential to the farmer in the more southern sections. In the South farmers have for generations been breeding corn simply for the. biggest ear. They get enormous ears, but by taking no account of the habit of the plant, they have developed a tall, long- legged corn that bears but a single ear and requires a greater distance in plant- ing, and hence makes a small product per acre. Southern improvers of the corn plant should work for a more dwarf and sturdy habit, and greater prolificacy. In other words, they should work for the character of plant they want without regard to whether it is a late ripening sort or not, since they have time enough to ripen any. But the Northern improver must take also the quality of early ripening in addition to the character of the plant and its prolificacy. Breed for a plant suited to your needs and not for one character of the plant alone. But it is not the corn plant alone that may be improved by selection. All our cereal grains, our cotton, tobacco and all other plants that are reproduced from seed, will yield to the same course of treatment and may be immeasurably improved. But to keep these improved forms to their standard the selection must be carried on the same way it has been done. A farmer gets an improved variety of corn, which has been selected on a certain line. He finds it really an improved variety. But he goes at once to work selecting seed out of the crib as he has always done, with- out reference to the character of the plant that bore the ear, and soon he finds that the corn has changed its character and is no longer like the corn he got, and he concludes that the improved sorts soon run out. But it is simply because he has bred it on a different line from that by which it was originally developed. He has worked simply for a big ear while the introducer worked for the whole plant. Another point to be observed in the improvement of plants is to remove them from disturbing influences around them. We may have corn which shows very nearly the character which we wish to perpetuate, and it is sur- - rounded by stalks that have produced no ear, but have made an abundance of 380—Crop GROWING AND Crop FEEDING pollen on the tassel. The chances then are that the seed taken from the fine stalk will have been crossed by the inferior ones, and will take more of their character than its own. Therefore, in saving seed corn, we should make sure that none of the barren stalks are allowed to make tassels and thus to interfere with the process of seed improvement. I once undertook the im- provement of my tomatoes. I found one plant in the field which showed remarkable productiveness and fine, smooth fruit. It was surrounded by rough and undesirable plants. If I had taken the seed from this plant it would have been crossed by inferior kinds. Therefore I made cuttings from it late in the fall and potted them, and placed them in the greenhouse. They were there cared for as other greenhouse plants are, and more cuttings were made late in winter. By spring time I had plants enough to set a considerable area and all of the same identical habit, and could now save the seed with some certainty of getting plants more nearly like the original than if I had taken seed at first. These seeds were sown the following year and another selection made and carried over from cuttings, and in a few years I had a tomato which I have never seen excelled. Unfortunately, after years of effort the stock was lost in fire. I give this as a sample of what may be done by in- telligent effort with almost any of our garden vegetables and flowers. There is no branch of cropping either in field or garden, more interesting and profitable than the improvement of cultivated varieties. Form in mind the ideal plant which you wish to produce and annually select seed from plants that come nearest to your ideal plant. Never select for a single character in the plant. If you select simply for big ears of corn you may get the big ears along with other undesirable characters. If you select for a big tomato, you will get that, but it may be unproductive and of bad shape. In plant breeding we must take into consideration all the characters we wish to per- petuate in the plant, and try to breed out all the bad features by avoiding them. The improved tomato of today is the result of long-continued crossing and selection, for the purpose of getting the crooked, but solid and meaty Mexican tomato inside the smooth skin of the old smooth, but hollow tomato. It is always trying to get out, apparently, and hence constant selection is needed to keep a variety near the type. While we can, to a certain extent, get plants into the habit of coming true to seed it requires constant watchfulness to keep them so, for there is always a tendency to break away from the inherited form and to sport into others. A break of this sort may be an advantage and a starting point for a new variety found. I have recently had my attention called to a curious instance of this.. A gentleman has a tree of the old Blood peach, which has for years borne the same peach, and this peach is of such a fixed type that it commonly comes true when raised from PLANT BREEDING—31 seed. But the past season, the tree in question abandoned its habit and pro- duced a crop of white peaches instead of the typical ones, blood red to the seed. It is impossible to explain the cause of these reversions, or “sports,” as the gardeners call them. But when we find these variations from the normal type, we can frequently make them permanent by propagation. Many years ago, at Kenansville, N. C., Rev. Mr. Sprunt found a shoot on a Safrano rose bush in his garden, which made a flower of a lemon yellow color, whereas the Safrano is a buff colored rose. The sporting shoot was used for cuttings, and from this variation we have the Isabella Sprunt rose. Many other florist’s plants have originated in the same way. But in plants that are annually grown from the seed, it is necessary to fix by selection through years, the hereditary habit of coming true to the desired type. It is in this way that the races or strains of certain plants have become established. Carelessness in the selection of seed is the main cause of most of the degeneration of types that bother the farmer. He gets a corn or a wheat of a certain variety, which has been bred to its present state through a long series of years, by selecting towards a well established ideal plant in the mind of the grower. When he has brought it to a point of com- parative perfection it is sent out, and at once men who have different ideals or none, get hold of it, and the tendency to variation which all plants possess, starts it off in various ways, and while the seed lists continue to give the name of the variety the seed has often been bred away from the original type in to a variety of forms. A neighbor of mine many years ago, sent North and got seed of the King Phillip corn, a variety of a dark brownish yellow color, with a small cob and broad, flat, flinty grains. His idea was to get an early ripen- ing corn for late planting on the low lands near a river where the soil did not dry out early. Under his mode of selection the corn has assumed an entirely different type, and the only point in which it now resembles the King Phillip is its color, for the number of rows on the ear has doubled, and the corn is a * dent instead of a flint, and is now more similar to the Leaming. He selected simply for the largest ears, as is the common practice among the majority of farmers. Since the Indian corn is more susceptible to improvement than most of the crop plants grown by our farmers I will here give the method I have heretofore advised in regard to the saving of seed corn. If the grower is in the northern limit of the corn belt, he will have to pay attention to the earli- ness of the variety he wishes to secure. In the South this item may be entirely ignored, since we have plenty of time to mature any corn. I would begin with the best variety attainable in the section where the corn is to be grown, for it is far better to start with an acclimated corn than to get a 32—Crop GROWING AND Crop FEEDING variety from north or south of the locality. Therefore get the best corn in your neighborhood, and plant a patch especially for seed. Give it the best of care in the preparation of the soil, the manuring and the cultivation, for a complete development is what we want first. Do not crowd a lot of plants in one hill, but plant singly in the rows. Now watch the corn as the tassels first show, and go through it and cut out every tassel before it ripens, from every hill that does not promise to make an ear; for these barren stalks are strong males and their pollen will have a deleterious influence on the plants around them. ‘Then, as the crop matures, mark the stalks that come nearest to the type of plant you are after. In the North, have an eye to the earliness of the plant as well as the other characteristics. In the South we need to breed towards a shorter and more sturdy plant, and to get away from the long- _ legged style so common, in which the ears are almost out of reach and are borne singly on the stalks. Select for productiveness, by marking only those with two or more ears. In the South, select for the seed ear the lowest one on the stalk, and this will generally be the smallest one, but it will inherit a tendency to form another ear above it, and we need this as well as the tendency to grow nearer the ground. In the North it may be best to save both ears. From the corn thus saved plant not only your entire field, but another seed patch, and on this seed patch, practice the same plan of selection, always keeping in mind the ideal plant you wish to establish. As the number of ears on the plant increase, and the productiveness of the variety is established, we would select for the general character of the plant year after year. The southern corn has become long-legged from the constant practice of selecting the largest ears in the crib. These large ears are commonly the only ones on the stalk, are usually borne high above the ground, may have been surrounded in the field by a multitude of barren and inferior stalks, and, as it is the pollen around the plant, rather than its own, which sets the grains, the plant- ing of the big ear will often lead to disappointment. If every farmer paid the proper attention to the selection of his seed corn, the crop all over the country would be immensely increased without any additional acreage. The cotton farmer in like manner should have his seed patch and select for the ideal cotton plant, and not merely for big bolls; and in all our annual crops plant breeding in an intelligent manner would greatly increase the average yield. But as the majority of farmers will not undertake this work, it leaves a wide field for intelligent effort for those who do, for they will be able to get a greatly increased price for their well bred seed from those who are not disposed to take the trouble. Not long since I had a letter from a North Carolina farmer saying that he had been practicing the method of saving seed corn which I had advised, and that his crop had increased in pro- PLANT BREEDING—33 ductiveness to such an extent that his neighbors were wanting his corn for seed. Such is always the case with the improvement of any of our crops, and shows that the reward of intelligent effort at improvement is certain. IMPROVING THE COTTON PLANT. There is no plant grown by our farmers which will yield more ready re- sults from intelligent selection and breeding than the cotton plant, and there is no plant grown in the United States of greater commercial importance. In fact, the greater part of our foreign commerce is founded upon the fact that we lead the world in the production of this great staple, and yet there is no farm plant that has been so persistently neglected by plant breeders. Of course here and there thoughtful men in the Cotton States have done much for the improvement of cotton for their particular section, and for.a while the varieties produced by them have a certain popularity. But soon the careless methods of selection among cultivators in general, change the character of the plant, and the ideal plant towards which the originator was working is lost sight of and a deterioration is the result. There is no one point in which there is greater need for intelligent effort on the part of the agriculturists of the Experiment Stations in the Cotton States, than in the improvement of varieties of cotton for the different sections of the cotton belt. In fact, the whole matter of plant breeding should claim the special attention of Station workers, for in no other way can the workers in agriculture and horticulture more efficiently aid the farmer and gardener, than in the production of more prolific plants of the various crops and the increase in the quality of their products. Here and there this matter has been receiving attention, and the real improvement in the cotton plant dates more from the origin of Experi- ment Stations than during any previous time. The cotton grower, like the grain farmer, has too long been aiming at special features in his product, rather than the general development of the whole plant. The corn grower © of the South has worked simply for a big ear. He gets this at the expense of prolificacy and gets a tall and ungainly plant. The cotton grower is en- raptured by a big boll, and fails to see that when breeding simply for a big boll he is getting a long legged “weed.” No real improvement can be effected in any plant that proceeds upon the selection for a single feature of the plant. The cotton grower wants, of course, as large a boll as possible, but he does not want the large boll at the expense of yield in general. He likes a good length of staple, but he does not want the long staple at the ex- pense of late maturity and weakness in the constitution of the plant. Hence ~~ 34—Crop GROWING AND Crop FEEDING anyone who attempts the improvement of any of our crop plants must study the character of the whole plant, and not attempt to breed for characters that are antagonistic to each other. Our southern farmers readily recognize the fact that there are good and poor varieties of corn, wheat and other crops, but the great majority of the growers seem to think that cotton seed is simply cotton seed, and take very little thought about it so long as it will germinate and grow. The result is that only here and there have there been men who have given any attention to the selection of improved varieties of the cotton plant, and when these improved varieties are sent out among farmers they are delighted with some of them for a while, and then, having secured the improved strain, they assume that they have it for good, and go ahead as they formerly did, get their seed from the general crop at the gin, and the variable force so strong in the plant, soon takes it out of the strain into which care has bred it; and though the grower claims that he is still growing the variety, he has simply allowed it to run back to an inferior variety and finds it no better than the others. It is not the fault of the improved variety, but of the careless grower. So long, then, as the great mass of cotton growers will take no pains in the proper selection of their seed, there is room for great profit to the grower who will work in an intelligent manner to produce, for his own use at least, a cotton that will prove of increased productiveness and quality. Mr. H. B. Mitchell, an intelligent cotton grower in Georgia, writing in regard to this matter, says that he has proved the utter fallacy of the notion that any kind of cotton seed is as good as any other. “Starting out with un- improved seed making one-fourth of a bale per acre, we have, with improved seed and careful selection each year, produced a cotton which, under very ad- verse conditions, yields a bale per acre, and from which we are satisfied the limit has by no means yet been reached. 'To improve seed, the first of Sep- tember we go over the cotton, marking such stalks as evince the highest points of merit. The cotton from these stalks we pick in advance of the regular ~ cotton pickers, rejecting all damaged or immature bolls, and spreading as picked, till thoroughly dry. It is next carried to gin, the gin completely cleaned out, and swept around, a large sheet spread down to receive the seed, which is then sacked up and so kept till hauled to the field at planting time. Were it not for bees there would be no trouble in keeping the cotton pure, but they bring the pollen from fields of unimproved cotton, causing a good deal of mixture.” Mr. W. E. Cole, of Cartersville, Ga., writes: “I was raised on a cotton farm in the old South, and no care was taken in the saving of the seed, but it was simply taken from the general seed pile at the gin in the fall. AsTI grew older I began the study of the cotton plant more closely. I noticed PLANT BREEDING—35 that some stalks produced more lint than others and of a better quality, while some had hardly any as the seed was black and lintless, and these, of course, had their influence on the plants around. I began to think that if one could get rid of those black and lintless seeds it would be a great improvement in the cotton. (Lintless seeds bear the same relation to cotton as barren stalks do to corn—W. F. M.) But upon noticing more closely I found several varieties of cotton in the same field. Some was storm proof, while in others the cotton would fall from the boll in the least shower of wind or rain. In 1897, while picking cotton, I found a variety which suited me better than any I have ever seen, as it produces more and larger bolls and lint of a superior quality, being long and fine and the seed of small size. When the season was over I had fifty pounds of seed cotton of this variety. I took it to my ginner and gave him the lint to take the seed out clean and separately. He cleaned his gin of all seed that was in it, and fed it through by hand, so that I had a bushel of clean seed to take home. In the spring this was planted on an acre, well cultivated and thinned to eighteen inches apart in three-foot rows. It made a rank growth and we had to lay it by the-last of June, as it was then too rank to get through. When fall came it was a pleasant sight to look upon, the stalks averaging 40 to 50 bolls and some as many as 80 well devel- oped bolls; and would pick nearly a pound of cotton. I cleaned 1,000 pounds of lint from that acre and got seed enough to plant my entire crop the following year. I sold no seed that year. One of my neighbors contended there was nothing in selected seed and I gave him a bushel of my seed, which he planted in the middle of his field with mixed varieties on either side, to give it a fair test; when fall came he was thoroughly convinced, as the selected seed made double the crop of the mixed seed on the same ground. I make 35 to 50 per cent. more cotton than with mixed and unselected seed.” These items of experience, from practical cotton growers, show plainly that there is no crop more amenable to improvement than the cotton crop, if the seed is wisely selected. If every grower of cotton would take the same pains the crop could easily be doubled without any increase of acreage, and there would be more profit at low prices than there is now at fair prices. Since the price of cotton in this country is almost entirely dependent upon the size of the crop, and a large crop is apt to run the price down to a point at which a careless grower finds no profit, it is evident that if a care- ful man, by intelligent selection of seed, can double the product of his area, the selection is well worth looking after. But, as we have said, any selection for the improvement of the product must take into consideration the whole plant and its surroundings. The habit of the plant has a great deal to do with the size and character of the 36—Cror GROWING AND Crop FEEDING crop. A cotton plant that habitually grows long-jointed and single-bolled can never be as productive as one that is more compact in habit and makes twin bolls. Long staple is a good feature, but if mere length of staple is the only feature looked after it may be accompanied by other less desirable characters. Hence, in the improvement of cotton, it is desirable to get to- gether the plants that have certain desirable features, though they may not all be combined in one plant. But by planting together the ones that have at least one feature we are after, and taking them away from the influence of plants like the lintless ones, we may by degrees get the desirable features combined in one variety, if we annually work towards an ideal. Mr. Cole was very fortunate in making such an advance in a single season, but if the same selection is not followed up the variable character of the plant will soon run the cotton back to its former mixed character. The permanent improvement of no plant that is annually reproduced from seed can be effected in a single season. We must patiently, year after year, select towards the ideal we have in mind, until we have established hereditary tendencies to come like the seed plant. Only after years of careful selection can we claim to have an im- proved variety. And here is right where there has been more failures than in anything else connected with the cotton crop. One grower, like Mr. Cole, finds plants of extra quality and saves the seed. The result is an improve- ment. But the plants selected from were surrounded by others of inferior character, and, as Mr. Mitchell says, the bees are always bringing pollen to the blooms, for there is a great deal of nectar in a cotton flower, and the result is that the variety is not uniformly the same, nor permanent. The plants for seed should annually be planted in a section by themselves, and all inferior plants that vary from the type sought should be rigorously rogued out. No matter if your entire crop was planted that season from selected seed of the year before, save no seed but from the seed patch where the watch — has been kept on it, and finally you will get a real race, or strain, of improved cotton that will be permanent. I have treated thus fully on the fruit and the seed, since upon these depend all the improvement we are to make in our cultivated plants that are to produce the crops we sell and use. And there is no one point in farm economy more neglected than the breeding of the plants we cultivate. Seedsmen fully understand the great value of pedi- gree in their seed stocks, and pedigree in a plant also that in an animal, comes through thoughtful and persistent breeding towards an ideal plant or animal. We have treated of the selection of seed in the corn and cotton plants as types of two great crops that are of interest to two large classes of growers. But the improvement through selection is not confined to cotton and corn. There is not a crop grown on the farm that will not yield improved results to the PLANT BREEDING—37 intelligent plant breeder. The broom corn grower can increase the length and quality of his brush and get it on a plant nearer within reach by careful selection and the growing of a seed-stock by itself, for no permanent advance can bemade so long as the seed-stock is subject to disturbing influences around it. We have been hearing a great deal of late years about the need for seed testing under Government control, and our great Department of Agriculture has, until recently, done a good deal of laboratory testing of seeds. While this work has a certain value in the determining of the clean character of the seeds and their germinating quality, it does not go far enough to determine anything of real value to the cultivator. The wide awake gardener, farmer or seed grower lays more stress upon the pedigree of the seed than upon the mere matter of percentage of germination. Of course a fair percentage of germinating power is essential in any seed that is to be planted, but the wise cultivator will take seed of a lower germination test than another if he knows that it has a better pedigree behind it. The laboratory germination test proves nothing in this regard, and, in fact, would not show whether a certain sample was cabbage seed or cauliflower or some other cruciferous plant, or whether a certain sample of beets was an early or late variety. All that the laboratory test proves is -the per- centage of pure seed free from trash and weeds there is in a sample and the percentage of these seeds that will germinate. The only real test of seeds is that practiced hy the best seedsmen who run farms at great expense, for the sole purpose of testing the seeds they sell, in the same conditions that their customers must be under; and also by the workers in the Experiment Stations in their variety trials. Intelligent seed growers must of necessity understand the laws of nature under which all their at- tempts at improvement must be carried out. It is an easy matter for the gardener who is propagating plants from cuttings, buds, grafts and layers to catch and make permanent a certain variation in his plants that may be desirable, for he is simply reproducing that identical plant; and he can retain the variation at once and make it permanent, as I have shown, in the instance of the rose grown from a sporting shoot, which at once makes a new variety to be cut into thousands and put on new roots. But in the case of the plants annually grown from seed there is a set of very different conditions. Plants are infinitely variable, and the blossoms that are to form the seeds are subject to infinite interference from insects, winds and the neighborhood of other plants of the same species. Plants of a vigorous character are always tending to break away from the line of their breeding, and if the grower slack in his efforts, or loses sight of the ideal towards which he is selecting, nature makes a reversion, and it may be towards an inferior type. Hence, as 38—Crop GROWING AND Crop FEEDING we have said in the case of the cotton of Mr. Cole, it is not enough to have made a start. It must be kept up, and only constant vigilance will keep any plant true to type and above its fellows. Therefore we would lay down the following rules for those who would improve their cultivated crops: 1. Fix well in mind the type of plant you wish to grow, and never for an instant lose sight of it. 2. Begin by selecting the plant that comes nearest to the type, and do not expect to get your ideal all at once. 3. So far as practicable, remove inferior plants from the immediate vicinity of your selected plant; save seed from the selected plant only. 4. Plant the selected seed as far removed as possible from any other plants of the same kind, and then rigidly root out every plant that falls below the first selection; save seed only from plants that show a decided advance towards the ideal plant you have in mind. 5. Never breed for a single character of the plant, but take the whole plant into consideration. If you breed simply for a big ear of corn or a big boll of cotton, you may get these at the expense of other desirable characters ; but take the whole character of the plant, its habit of growth, its general productiveness and every desirable character, so as to get not only the kind of product you want, but get it on an ideal plant. If you follow this up with patience, year after year, always remembering that what you want is seldom what nature would place in the survival of the fittest, and that any relax- ation of effort on your part will give nature a chance to undo your work,— you will finally find that you have a race of seed on which you can rely with certainty as to the result, you will find that intelligent seed merchants are ever on the hunt for the men who have sense enough to study and im- prove their plants, your neighbors will take an interest in your crops and there will be more money in your purse, and you will be a benefactor of your race by improving production. While the improvement of the soil for the production of crops is the main object of this book, there is no doubt that we will be excused for dwell- ing so long on the seed and its selection, for there is fully as much to be gained in this way as by the improvement of the soil in which they are grown. No matter how a farmer or gardener may improve his soil in productive capacity, if he plants seed of inferior character his crops will not be what they should be. If our farm readers could visit, as I have done, the seed farms of the seed growers, and the testing farms of the great seed dealers, they would be amazed at the minute care that is needed to preserve and improve the seeds they purchase; they would no longer wonder that first class seeds must bring a fair price, and they would realize that the most costly thing a man PLANT BREEDING—39 can buy is poor seed. Not merely seed of poor germinating power, but seed destitute of breeding, and, like a scrub cow, not entitled to register among well bred animals. And yet in all their purchases there is no one point where farmers are so short sighted as in the purchase of seed. This is particularly true of seeds of forage and grass crops, which are so generally purchased. A farmer finds in the hands of a commission merchant a lot of clover seed right from the huller, and buys it, solely because it is to be had for a dollar or more less per bushel than seed that a seedsman has carefully recleaned. The re- cleaned seed is usually cheaper by reason of the greater number of clover seed in the bushel, and it is infinitely cheaper in the fact that the farmer sows no weeds with it. The larger part of the weeds that infest our farms and re- duce our crops, have gotten there in foul grass and clover seed. A farmer recently wrote me that his farm is so completely stocked with the narrow- leaf plantain gotten in clover seed that he can no longer make a decent crop of clover. I never read a better sermon on the value of clean seed than his let- ter. Buying cheap seeds, or rather low priced seeds, is “saving at the spigot and losing at the bunghole.” Better pay two prices for clean clover and grass seed than to have the inferior given to you. Farmers should be students of seeds in more ways than one. They should learn to know seeds of all sorts when they see them. For instance, take a sample of clover seed. It may have in it as a purposely added adulteration (as is practiced by some), seeds of the worthless yellow trefoil; and the farmer who has not studied seeds will not detect the adulteration till he sees his fields yellow with the trefoil in- stead of red clover. It may have in it seeds of dodder that will speedily de- stroy clover, and they will pass muster with the careless observer, by reason of their yellow color. A good magnifying glass is of greatest import- ance in the selection of seeds, and a knowledge of seeds is quite as important. Hence every farmer should get a collection of the seeds of all sorts of foul weeds, and get completely familiar with them, so that he can at once detect what impurities are in the seed samples he is examining. The seed is the starting point of the crop, and if the crop is to be a success the seed must be the best. The seed is also the starting point of the weed, for a weed is merely a plant where it is not wanted. Hence if we do not want weeds we should be extremely careful never to sow them. Many thousands of acres of the best mowing lands are so foul with weeds that there is more weed in the hay than timothy or clover, and the losses to farmers all over the land, through foul clover and grass seed, are so great that we cannot too urgently insist upon the importance of the seed. CHAPTER IV. THE SOIL. While, as we have seen, plants get by far the larger part of their structure from the air, they get by far the most important matters from the soil, so far as the making of a crop is concerned.. While the carbon-di-oxide in the air and the oxygen itself are essential to plant growth, the soil and the matters which it furnishes are also essential. Some idea, therefore, of the origin of soils and their nature and composition is essential to a proper understanding of plant life, and the means for best sustaining and improving it. Back in the eighteenth century, the great French chemist, Lavoisier, enunciated the great truth that in this earth nothing is created and nothing is destroyed. That is, all substances that now exist have existed from the beginning and will always exist. We cannot create anything; we can simply make new combinations of things already existing in soil and air, and when this new combination is destroyed, these matters go back to the forms in which they were acquired. We grow a tree from materials existing in soil and air. Finally we burn the tree and get back the heat it originally got from the sun. It is destroyed as a tree, but the carbon-di-oxide and water and nitrogen have gone back where they came from, into the air; we have left a handful of ashes, representing what it got from the soil, and these we put back in the soil, where they can be used over again to build other plants. The elements that went to make up the tree are still in existence, just as they were before they were combined into a tree; and so in soil and air nature is simply working over the same old materials and forming new combinations. The soils that form the foundation for our farms are all the result of the gradual breaking down of the old earth-crust, and the crumbling and pulver- izing of the rocks through natural agencies. When the earth first cooled from a molten ball, the old, crystalline rocks were formed, and in the lapse of ages other rocks were formed under water, and afterwards were elevated. As soon as rocks are above the sea the process of disintegration begins. The (40) THE Sort—41 waves of the ocean dash upon them and grind them into sand. Rains, by imperceptible degrees, dissolve them. Water gets into the cracks and by freezing, forces off particles large or small. It is, therefore, by this weather- ing process that the materials for our soils have been formed, and then washed down from the higher to lower elevations, and spread abroad over the rocky base. Many soils are formed from the gradual decay of the rocks on which they rest, and are, therefore, of the same composition as the rocks themselves. Other soils have no connection with the rocks beneath them, but are formed by the decomposition of other rocks, mixed with decayed organic matter, and brought down in flood and deposited on the low lands, making what are known as alluvial soils. Then, too, in many instances the valley lands, known as limestone soils, are the beds of ancient lakes, in which the lime- stone was formed from the shells of mollusks; the alluvial soil was afterwards accumulated above the rocks, and the soil really contains less lime than soil of a very different formation. The mountains of the present day are far lower than they were when first formed, and the constant wearing away is still going on; the streams still bring down from the mountains vast amounts of fresh soil to accumulate on the flats and river bottoms, gradually forming more alluvium. Every hill that is in cultivation is constantly being carried off to the lower lands; hence, the low lands are of varying nature, sandy, clayey or silty, according to the kind of material brought down to them from time to time. Of course, there is a great variation in the mineral constituents of soils every- where, depending on the chemical make up of the rocks from which these mineral matters come. Low lands about the bases of the hills are generally fertile, not only because of the masses of soil transported to them in floods, but because the rain water running down to them from the hills carries the most soluble elements of fertility with it, to be absorbed by the low-land soil. The low lands are constantly being extended and elevated, and the ponds are constantly being filled, till finally the smaller lakes become fast land, being filled up by soil washed down from the hills and with the remains of the vegetation they produce themselves. But while all the soft earth above the solid rocks is called soil, the soil — that the farmer is mainly concerned with is that upper portion that has be- come altered by exposure to the effects of the air and the carbonic acid in the rain water, and which has become mixed with the decay of vegetable mat- ter and has assumed a darker color by reason of this vegetable decay. We call this the soil, and all that lies below is called the subsoil. They may be, and generally in our upland soils are, identical in their composition; and differ 42—Crop GROWING AND Crop FEEDING only in the fact that the surface soil has accumulated humus from the vege- decay, and, by being exposed to the action of the oxygen of the air, has been brought into a condition in which it more readily gives up to plants its store of food. The original source of the humus in the soil was the natural growth on the land. Nature does not like bare ground and she soon covers it with some sort of vegetation. Among the grass and weeds the seeds of trees find lodge- ment and grow, and soon a forest is formed. The trees send their roots down deeply into the soil, and then scatter their leaves on the surface to gradually decay, year after year forming more and more of the black decay, and increas- ing the fertility of the soil. Then, after a while, some one comes along and cuts the forest down, and begins to cultivate the soil. He finds it fertile and productiye, and he goes right along cultivating it in the same crop year after year, and it grad- ually becomes less and less productive, till finally it is abandoned, to grow up once more in grass and weeds and once more be taken by nature for a new forest. Then, on the soil which was called worn out, but which was simply rendered unproductive by bad treatment, nature, by her unaided forces, with no fertilizer but that which she gathers from her own bosom, makes a grander growth than the man who wasted the soil ever grew. And she repeats the same process that formed the soil in the beginning, bringing up from deep down in the subsoil matters for the growth of trees, and spreading it year after year on the surface. Then another fellow comes along and makes fire- wood out of this second forest, and goes to work to reduce again the soil made fertile by the forest. He sueceeeds sooner than the first, for the accumu- lation is more recent and lighter. But this man cannot afford to throw the land out and clear another piece as the first possessor of the soil did. So he begins to dribble a little commercial fertilizer on it to induce the soil to yield him crops to sell. He does this year after year, and keeps culti- vating the land in cotton or corn or wheat, as the case may be, and he wonders that the land seems to grow poorer and poorer, and the farmer gets poor too. But let him stop in despair, and nature will grow a grand crop again on that land without calling in the aid of the fertilizer man. Of course, we cannot, in our modern agriculture, adopt the methods that nature does exactly. Life is too short for a man to wait for the forest to grow and enrich a piece of land for him; he must get the same results in a far quicker manner. Get- ting a hint from nature’s methods, we can do all that she does, and do it in a very brief time compared with her work. That the soil has not been ex- hausted as was thought, is shown by the fact that the forest grows readily on this land when it is left to its own resources. It had simply declined to give _{ "=u, THE Sorr—43 up its plant food as rapidly as we needed it for crops, but was still in condi- tion to gradually give it up to the slower demands of the forest. The fact is, that no land, originally fertile, and of good mechanical composition, is ever worn out. It may be brought into a very unproductive condition, and its mechanical condition be made unfavorable to the production of crops, but it will still have the matters in it that can be made available. By proper tillage and the use of restorative crops, such soils can be restored to their original productiveness through their own resources. ‘The process of restor- ing such soils in this way would be too slow for our modern ideas, and hence the soluble matters used in a concentrated form as fertilizers have their legitimate use in the upbuilding of the modern farm. In many cases the soil has simply been robbed of the humus or vegetable decay, and is still as rich in mineral plant food as ever, but its mechanical condition is such that plants cannot thrive in it as they did. The soil runs together and bakes hard after rains, and the cost of tillage is greatly increased, while the productiveness of the land has decreased. It simply needs a restoration of the black humus that made it mellow and re- tentive of moisture, and rendered the plant food in it more available. There are many soils called worn out which never had much to wear out. A little accumulation of vegetable matter on top of a deep sand was soon used up, and a blowing sand is the result. Such soils had far better be left to pine and scrub oak. Thousands of American farmers find themselves confronted by the prob- lem of “worn out” lands, and how to restore them to productiveness, and it is with the hope of aiding them in the solution of the problem in an economical manner that this book has been written. LIVING SOILS AND DEAD SOILS. There are in many sections of the country, large areas of land originally fertile and productive, which would have remained permanently productive, had they been properly managed. Their condition is due largely to the fact that life has abandoned them, because the low forms of plant life that carry on the changes in the soil and make plant food available, have been starved out, and no addition simply of concentrated plant foods will take the place of. the foods on which the bacteria of nitrification exist. When these lands were cleared from the forest, or broken from the prairie sod, they were full of the black decay of organic matter. They were retentive of moisture and gave up their plant food to the cultivator in abundant crops. Year after year the process was repeated and the soil robbed. No steps were taken to keep up 44—-Crop GROWING AND Crop FEEDING the amount of the black humus that made the soil originally productive, and gradually it was used up. The minute organisms, whose life is spent in the transformation of this organic matter into forms adapted to the use of crops, perish by reason of the burning up of the humus. ‘There is nothing for them to work upon. The soil runs together and bakes under the influence of the rains, and rapidly dries out, so that there is a lack of moisture for the solu- tion of the plant food it contains. The oxidizing influence of the air fails to penetrate the compact soil, and though it still contains all the plant food needed for big crops, it becomes an unproductive soil because plants can no longer get what the soil has for them in abundance. It isa dead soil. And all over the land one sees these dead soils, made so not only by the using up of the humus but by the settling of the soil into a sour mass; where formerly it hardly needed drainage, now it is sour, not from lack of food but from lack of the ability of the air to penetrate and mellow it. That humus may not have had in it nearly the amount of plant food that still remains in the soil, but it was the preservative agent in the soil, the only thing that kept life there, and its absence means death to soil and crops. One of the most thoughtless advocates of commercial fertilizers some time ago said in print: “Give humus a rest, we can get along without it if we have plenty of soluble fertilizers for our crops.” All over the country, and especially in the South, farmers have been giving humus a_ rest, and their lands have become less and less productive, notwithstanding the millions of dollars’ worth of commercial fertilizers they use upon them in the vain hope that they will take the place of permanent fer- tility. If the worn soils are ever to be redeemed it must be through the get- ting back there of that bacterial life that carries on the changes in organic decay, and these can only exist when there is this organic decay present. A soil filled with bacterial life is really a living soil and a fertile one, while one without it will always be less productive. It will be less productive, not only by reason of the absence of the organisms that release nitrogen in the soil, but by reason of its smaller power to retain moisture and heat and to dissolve the plant foods applied in the fertilizers. Last summer we applied a dressing of fertilizer to a crop of sweet potatoes on some of this dead land. The summer was extremely dry, and when the potatoes were dug the crop was only such as the soil would have made alone, for the fertilizer was lying there as dry as when applied. On another piece where the humus had been to some extent restored, the fertilizer acted well, simply because there was moisture retained there to dissolve it, and the plants got it. If there were no living organisms to help us in this humus, its mechanical effect would alone give it sufficient value to warrant every effort to retain and increase it. ff im THe Sorr—45 HOW TO DETERMINE WHAT THE SOIL NEEDS. When men first began to be interested in the chemical composition of soils, and the improvement of their productive capacity, they jumped to the conclusion that a chemical analysis. would show them just what was lacking; and by adding this they could restore the soil to its original productive character. But chemical analysis at once showed them that there may exist very large quantities of all the needed plant foods and yet the soil remain in a very unproductive staté, owing to the fact that the plant food it contains is in a condition insoluble in the soil-water, and, as the plants cannot take anything through their roots that is not completely dissolved in the soil- water, they starve in the midst of potential plenty. Therefore, while soil analysis has its use, it can never be depended upon to tell the farmer just what his soil needs to render it productive, so far as the food supply is con- cerned. The fact is, too, that soils vary widely within narrow areas, and an analysis of the soil from one portion of a field will not give a correct idea of the nature of the soil in another portion. As the uselessness of soil analyses became apparent men began to study the needs of plants, and the way in which different crops use the food elements. While all plants use the same kinds of food from the soil, they use them in varying proportions, one needing more nitrogen, or more phosphoric acid, or more potash than another. Acting on the belief that from the analysis of the plant we could accordingly propor- tion the different plant-food elements for each crop, the manufacturers of fertilizers began to make what are known as special fertilizers, and recom- mended one for one crop and another for another. ‘There seemed to be a rea- sonable basis for such notions, but really there is not such a serious difference after all, in the manurial requirements of plants, while there is a wide dif- ference in the manurial requirements of soils. If chemical analysis, then, will not materially help us in deciding what our soils need, how are we to ascertain what we should apply and what we need not buy? All farmers know that without some such knowledge they’ are likely to be wasting money in the purchase of matters that they do not need on their land. This is a matter which every farmer must find out for himself, and no one can find it for him elsewhere than right on his own farm. Hence every farmer should be, to some extent, an experimenter. He must experiment with his land not only to discover its food needs, but also to find whether through imperfect preparation and imperfect drainage he is not obliged to buy plant food which he does not need at all. Of the methods of this experimentation we will treat in detail elsewhere. First let us see what things are essential in the soil in order that plants may grow. CHAPTER V. PLANT FOOD. We have already seen that by far the larger part of the bulk of the plant comes from the air, through the assimilation of carbon by the green leaves. By burning the plant we drive this off into the air again, and with it also the nitrogen, which came to the plant from the soil, but originally was derived by the soil from the air. What we have left in our ashes shows the mineral matters that were derived from the soil. Chemical analysis shows us what these were. We find that the ash consists of various combinations of what are known as elements. An element is matter reduced to its final form, or something in which we can find nothing else of a different nature. These elements are either metallic or non-metallic. The element nitrogen, for instance, is a gas existing, as we have seen, in all air. Iron is a metallic element. None of the elements are used by plants as pure elements. Nitrogen must be gotten into the soil in combination with something else to hold it there and render it soluble in the soil-water so that plants can take it up, for the ordi- nary green plants cannot use the free nitrogen gas. Nor can they use a metal like iron, until it is acted upon by the acids and made into an oxide ora sulphate, and even then they use very little of it. It has been found by care- fully conducted experiments that plants cannot grow without a supply in the soil of some combination of the following elements: Nitrogen, potassium, magnesium, calcium, iron, phosphorus and sulphur. As we have already said, while iron is essential, it is used in very small quantities, and all soils in which plants make green leaves will be found to contain an abundance of iron. Magnesium and calcium (the element from which lime is formed) are also generally in abundance for all the needs of them as plant food direct. Of the further use of lime we will speak more fully hereafter. (48) jj-. PLant Foop—4? The elements which become deficient in the soil through long cultivation and the removal of crops are nitrogen, potassium and phosphorus. Any one familiar with the composition of commercial fertilizers knows that it is these elements in some combination which give them value. Nitrogen must be changed into the form of nitrate; that is, some combi- nation of nitric acid with lime or potash, making a neutral salt, before green- leaved plants can take it as food. Potassium must be changed by oxidation into potash in order that it may be dissolved in the soil-water. Phosphorus must be in the form of phosphoric acid, for the element phosphorus burns up at once on exposure to the air. It is generally combined with calcium, making the phosphate of lime, an insoluble compound, which is rendered soluble by sulphuric acid; and thus gives us a superphosphate of lime, which is available to plant life. Phosphoric acid is a compound of phosphorus, oxygen and hydrogen, but in phosphates the metallic bases replace the hydrogen. Nitrification, or the transformation of organic matter into nitrates so that green plants can get nitrogen, is carried on by minute organisms in the soil, and the life of these organisms depends on the presence of the organic matter in the soil; making it, as we have seen, a living, rather than a dead soil. Of this process of nitrification we will treat more fully further on. CHAPTER VI. SOURCES OF FERTILIZING MATERIALS. SOURCES OF NITROGEN. Nitrogen, as we have seen, is a gaseous substance which makes up for- fifths of the atmosphere, mingling with and diluting the oxygen so that it can be breathed, but never combining with it under ordinary conditions. It is the oxygen of the air upon which animals depend for respiration, but it must be diluted for this purpose, and hence the nitrogen is mixed with it, though nitrogen takes no part itself in respiration. Plants even, which need nitrogen as food, will die if confined in nitrogen gas alone. Ammonia is a hydrate of nitrogen which acts as a base in connection with acids. Thus with sul- phuric acid it forms the sulphate of ammonia, with carbonic acid, the car- bonate of ammonia, which is the ammonia we smell so strongly escaping from a heating manure pile exposed to the weather. Manufacturers of fertilizers always like to print the percentage of ammonia on their bags rather than that of the actual nitrogen, as the figures look larger. When you find the per- centage of ammonia thus on a bag you can get the true amount of nitrogen by multiplying the ammonia per cent. by 0.8235. Thus if the bag has 2 per cent. ammonia printed on it, this means that there is but 1.647 per cent of actual nitrogen. The source from which the nitrogen comes is a very important matter to the purchaser of the fertilizer, since chemical analysis may show that there is a large percentage of nitrogen present, but at the same time it may be almost entirely useless because in an unavailable form, and all that chemical analysis can tell you is that it is there. Hence it is important to know from what (48) SOURCES OF FERTILIZING MATERIALS—49 source the nitrogen is obtained. Pulverized leather scraps, hoofs, horn shavings, hair, will show on analysis a good percentage of nitrogen, but in such a form that plants cannot use it, being insoluble. Hence the source of the nitrogen is, perhaps, of more importance than the actual amount. There is at all times a very small and uncertain amount of nitrogen in the form of ammonia in the air. It is believed that plants do, to some extent, absorb some of the ammonia, but it has never been proved that they do. But there are varying amounts brought to the soil and within reach of the roots in the rain water. Then, too, during thunder storms, some of the nitrogen of the air is converted by electricity into nitrous acid, which is further transformed into nitric acid, and this in the soil forms the nitrates of lime, magnesia and other bases. It has been stated that this formation of nitric acid in the air is the only source of the combined nitrogen in the earth, but later studies of the work of soil bacteria have developed the fact that there are other and more powerful agencies at work in the getting of the free nitrogen into a form that plants can use. It has been estimated that in this country about six pounds per acre of nitrogen are brought to the soil annually in the rainfall, in the forms of ammonia and nitric acid. But the greatest source of the nitrogen in the soil is in the black, organic decay which we call humus. A soil well filled with the decay of plant and animal life will have a large nitrogen content, while a soil from which all the humus has been used up, or burnt out, will have very little nitrogen. This accounts for the superior fertility of freshly cleared land. It is true that the nitrogen contained in the humus is not at once in a condition to serve as plant food, but it furnishes food for millions of microscopic plants known as bac- teria, which are the means of carrying on the process called nitrification, through which the organic matter is broken down and its ammonia changed into nitrites and then into nitrates, which last is the form in which green plants can use it. A soil, then, which contains a large percentage of humus may be properly called a_ living soil, while one in which there is no humus, and from which the nitrifying bacteria have been starved out and have died, may be well called a dead soil. Nitrogen is an essential element in all living matter and the absence of nitrogen means death either in animals or plants. From whence, then, are we to get the various combinations of nitrogen needed in our complete fertilizers? It is always the element that gets away from us most rapidly in the soil, for if it is not taken up by plants when it gets into the available form of a nitrate, it quickly leaches away from the soil, and therefore we need to frequently renew the nitrogen in the soil. 50—Crop GROWING AND Crop FEEDING. All organic matter, as we have seen, contains nitrogen. But this can only be used by plants after the substance has completely decayed and the soil bacteria have transformed it into a nitrate. The rapidity, then, with which any organic matter decays, determines its value in plant feeding. Some forms, as we have noted, such as leather scraps, horn meal, etc., decay so very slowly that their nitrogen is of little use to plants, while other forms decay rapidly and soon come into an available shape. Pulverized fish scraps from the fish oil factories along the coast, or from the refuse of the fish canning houses, form a valuable source of organic nitrogen. The article made by the regular fish oil factories along the Atlantic coast is a richer article than that made from the refuse of the pack- ing houses, since the whole of the fish, after the oil is extracted, goes into the scrap, which is ground from the pressed cake. In some sections there are other refuse matters from the sea used in the making of fertilizers, such as crabs, but this cuts a very small figure in the general market and is available to few. One of the very best sources of organic nitrogen is the blood from the great abbatoirs, or slaughter houses, where animal products are packed for com- merce. It is not only rich in nitrogen, but it is in a form that decays very rapidly in the soil, and soon reaches an available form. It is important, however, to note the character of the dried blood offered for sale, since it may contain all the way from 6 to 14 or 15 per cent. of nitrogen. The best grade is always of a red color. If black, it shows that it has been charred in the drying, and has assumed more the character of leather, hence is less readily decayed, and has lost some nitrogen. Probably the cheapest form in which organic nitrogen can be bought, at least in the South, is in cotton seed meal. This contains between 6 and 7 per cent. of nitrogen, and a smaller percentage of phosphoric acid and potash. The exact percentages will be found in the table of analyses of the various fertilizing materials, given elsewhere. It is now largely used as a food for cattle, and when used in small quantities, in connection with carbonaceous foods, forms a valuable part of a ration. But there is a practice becoming common in the South, of feeding cattle on a ration entirely of cotton seed meal and cotton seed hulls, which is mischievous, resulting in very inferior beef, and in butter but little better than oleomargarine. Properly used the cotton seed meal is a valuable addition to a food ration, and it is only the bad method which I have uniformly opposed. Cotton seed meal decays rapidly in the soil, soon becomes nitrified and available to plants. In some parts of the country linseed meal is used to some extent as a fertilizer, but as a rule the price is prohibitive for this pur- SouRcEs oF FERTILIZING MATERIALS—)1 pose ; it should be used only as a stock food, and thus enrich the home-made manure. Castor pomace is a valuable source of nitrogen in limited localities. It usually contains nearly 6 per cent. of nitrogen, decays rapidly in the soil and is soon available as plant food. Another product of the great western slaughter houses is tankage. This is composed of the dried and pulverized waste matters from the slaughtering of animals, and is of a very varying nature. One form of the more concen- trated tankage may contain as much as 12 or more per cent. of nitrogen, while other samples will not have more than 4 to 5 per cent. of nitrogen, but a larger percentage of phosphoric acid than the concentrated form. The price of tankage, of course, varies with its composition, and a low-priced article is always one that has the least percentage of nitrogen. It is, therefore, im- portant to look after the analysis claimed for each sample. About the most worthless form in which one can get organic nitrogen is in the meal made from leather scraps.. Analysis will show that this con- tains a large percentage of nitrogen, yet it is almost worthless to the farmer, since the leather so long resists decay in the soil. The making of a fertilizer in which leather is used as a source of nitrogen, should be looked upon simply as a fraud. In the same class should be placed wool and hair waste, which can only be made available by dissolving in sulphuric acid. From the fat rendering establishments, where the dead animals from the large cities are utilized, there comes dried meat; which has value for nitrogen nearly as high as that of the dried blood from the slaughter houses. Formerly there was a rich deposit of natural guano with a very high per- centage of nitrogen on the Chincha Islands, on the coast of Peru. But this was long ago exhausted, and though we have occasionally so-called Peruvian guano offered for sale, it is far inferior to the old article; as it comes from localities where rain has washed out a large part of the nitrogen, and consists mainly of insoluble phosphate of lime. The exhaustion of the old Peruvian guano beds gave the first great impulse to the manufacture of commercial fer- tilizers, so that now the natural guanos make little show on the market, and being largely of a phosphatic nature are mainly used by the manufacturers of fertilizers. When any of these organic matters, containing nitrogen, decay, the first result is the formation of the hydride of nitrogen, or ammonia, from the com- bination of hydrogen and nitrogen. But green leaved plants, as a rule, do not use nitrogen in the form of ammonia. The bacteria in the soil which bring about what is known as nitrification, break down the ammonia and form the nitrogen into a nitrite. Another form of bacteria then takes up the work 52—Crop GROWING AND Crop FEEDING and transforms the nitrite into a nitrate, which is the form in which green leaved plants use nitrogen. Ammonia is manufactured as a by product in the making of illuminating gas, and also in the manufacture of bone charcoal for the sugar refiners. This is the source of the article in commerce known as the sulphate of ammonia. Large quantities are now made also in the manufacture of coke for the iron furnaces. In the sulphate the ammonia is in a very concentrated form, and will probably become more largely used as the price is reduced; though with many plants is seems at times to exert a poisonous influence. It is common to say that cotton seed meal and other organic matters have a certain percentage of ammonia, but there is really no ammonia there until the organic matter has decayed and the combination of the nitrogen has been made with the hydrogen. The more correct way would be to give the percentage of nitrogen in the matter which forms ammonia in decaying. But, as we have said, the figures for ammonia look larger, and hence manufacturers like to put it as ammonia in their claims. Pure sul- phate of ammonia contains 21.2 per cent. of nitrogen. In recent years there have been large discoveries of nitrogen in the form of a nitrate of soda, which is formed in large masses in certain parts of the western coast of South America where no rain falls. This is now probably the cheapest source of nitrogen for fertilizing purposes. We have seen that green leaved plants use nitrogen in the form of a nitrate, and that the organic nitrogen must be changed into this form in the soil before they use it. The nitrate of soda being already in the nitrate form is at once available for plant food. As it rapidly leaches from the soil in the rainfall this form should only be used while plants are in active growth. If applied during the dormant season much if not all of it will be lost by leaching. In making a complete fertilizer mixture, if nitrate of soda is used, it should always be ac- conipanied by a due proportion of organic nitrogen to ccntinue the supply after the nitrate is used up. The nitrate is useful in the first growth of the plant while the nitrifica- tion of the organic matter is going on, as it is immediately soluble and quite concentrated. It is often sold under the name of Chili saltpetre, (ordinary saltpetre being the nitrate of potash) and contains from 15 to 1A per cent. of nitrogen. Professor Voorhees, in his book on fertilizers, welt says that “The practical point, and the one of prime importance to the farmer, is, then, to know how to estimate the relative value or usefulness of these different products, what is the rate of availability as compared with the nitrate, and thus the relative advantage of purchasing the one or the other, at the ruling market prices. Relative values, however, cannot be assigned as yet, though careful studies of the problem have been made, chiefly by what are known as Sources OF FERTILIZING MATERIALS—53 ‘vegetation tests’; that is, tests which show the actual amounts of nitrogen that plants can obtain from nitrogenous products of different kinds, when grown under known and controlled conditions. The results so far obtained, while only serving as a guide, indicate that when nitrate is rated at 100 per cent. blood and cotton seed meal are about 70 per cent., dried and ground fish and hoof meal 65 per cent., bone and tankage 60 per cent., and leather, ground horn and wool waste as low as 2 per cent. to as high as 30 per cent. These figures furnish a fair basis for comparing the different materials, when used for the same purpose. If, for example, the increased yield of oats due to the application of nitrate of soda is 1,000 pounds, the yield from blood and cotton seed meal would be 700 pounds, the yield from dried ground fish and hoof meal would be 650 pounds, from bone and tankage 600 pounds, and from leather, ground horn and wool waste from 20 to 300 pounds.” As re- gards the last we are of the opinion that the increase would be nearer nothing at all. While these figures may be useful, we would suggest that the cultivator cannot depend upon the same results in practice for the varying conditions under which the plant food is applied, and the atmospheric condition after the application, might easily make the soluble nitrate the least productive. The practice of all good cultivators is to use the nitrate to some extent in a complete fertilizer mixture, but to place the main reliance for nitrogen for the crop upon the organic forms, since all of the nitrate of soda that is not used at once is rapidly lost to the soil and plants, and the cultivator who de- pends for nitrogen on the nitrate alone will often be disappointed in the result. In a number of experiments made at different Stations it has been shown that sulphate of ammonia, in a mixed fertilizer with the muriate of potash, acts asa plant poison. In fact, in certain conditions of the soil, it seems that sulphate of ammonia is about as likely to do harm to the crop as to benefit it. Even when the sulphate of ammonia is simply mixed with stable manure it has given decidedly injurious effects. When mixed with the muriate of potash there is a combination of the chemicals and the chloride of ammonia is formed, which is injurious to vegetation. Another source of organic nitro- gen which is available to the farmers in some localities, is the sea weed which accumulates on the sea beach after storms, and which is largely used by the farmers near the ocean. The sea weeds decay rapidly and furnish large per- centages of nitrogen and potash, but are lacking in phosphoric acid. They are so rich in potash that some authorities rank them among potassic manures, and when mixed with a due percentage of phosphates they furnish a fairly complete fertilizer. One great advantage in the use of sea weeds is the fact 54—Crop GROWING AND Crop FEEDING that they bring to the soil no weed seeds. The salt which they contain may act as a solvent of matters in the soil of value to plant life, and be to some extent serviceable in destroying fungi and insects in the soil. BARN AND STABLE MANURES. The greatest source of organic nitrogen on the farm is, of course, the manure made from the droppings of domestic animals. The care and proper use of the home-made deposit lies at the very foundation of successful farm- ing. No purchase of commercial fertilizers can fully atone financially for a waste of this home-made article. And yet there is no one thing on the farm generally so badly managed, and subjected to so much waste, as the barnyard and stable manure. It has been estimated that if the manure annually pro- duced by all the domestic animals kept in the United States was properly saved, its total value would be over two thousand millions of dollars. Prof. Roberts of Cornell has estimated that on a farm on which are kept 4 horses, 20 cows, 50 sheep and 10 pigs, there should be produced during seven months of the winter and colder part of the year at least $250 worth of manure, valuing it at the rate paid for phosphoric acid, potash and nitrogen in commercial fertilizers. And it is further estimated that one-third of the value of all the manure made is annually lost through bad management. This means an annual loss of nearly seven hundred millions of dollars in the United States, or an average annual loss on each farm of $83.33. This means that to keep up the waste made from selling crops this loss makes necessary the purchase of that much more of plant food to replace the loss, if fertility is to be main- tained. Every ton of hay sold from the farm removes plant food to the value of $5.10 if bought in a commercial fertilizer. Every ton of wheat carries olf from the farm plant food to the value of $7.75. Or, as Dr. Armsby has said, “A farmer who sells, for example, $10 worth of wheat sells with it about $2,58 worth of the fertility of his soil. In other words, when he receives his $10 this amount does not represent the net receipts of the transaction, for he has parted with $2.58 of his capital, that is, of the stored up fertility of his soil; and if he does not take this into account he makes the same mis- take a merchant would should he estimate his profits by the amount of cash which he received and neglect to take an account of stock.” But if, instead of selling all the products of the farm, a large part is retained and fed thereon to animals and the droppings carefully saved, a large part of this fertility is retained on the farm. Then, too, where the entire product of a farm is not only fed upon it, but some food which was grown on other land is purchased for animals, the farm may be kept improving without the purchase of plant SouRCES OF FERTILIZING MATERTAL—55 food in any other way. Such, however, can seldom be the case except in limited localities where the butter dairy is the sole business. Hence, in the great majority of cases, it is necessary to supplement the home-made accumulation with commercial fertilizers. But the farmer who neglects to save and care for in the best manner all the home-made manure is neglecting the true source of riches on the farm. A great deal of the neglect of home-made manure has doubtless arisen from the ease with which fertilizers can be gotten on the market, and over large portions of the country, especially in the Cotton States, there has been an utter neglect of stock feed- ing, and an entire dependence on the commercial fertilizers. Year after year the same crop is planted on the same land, and the chances are taken as to the result from the dribbling of a little fertilizer in the furrows. This gambling in fertilizers has brought ruin to many a fair acre in the South, where proper farming and the feeding of cattle would have brought fertility and riches to soil and farmer. The constant use of commercial fertilizers on the soil, and the clean culture of the crop, has robbed the soil of its humus, and put it into a bad mechanical condition, in which the fertilizers no longer have the power to produce the results they would under different soil condi- tions. One of the greatest values of barnyard manure is in the humus-making material combined in it, which makes it more retentive of moisture, improves its mechanical condition, and furnishes food for the microscopic plants that carry on the process of nitrification in the soil and prevent its becoming a dead soil. Into this lifeless condition much of the cotton land of the South has now been changed, and men say “we cannot grow good crops because our land is poor,” when it is poor farming which has made it poor. If the farm ever was fertile, the acknowledgement that it is now poor is evidence that the owner is responsible for its condition. But there are various qualities of the farm manure as well as of commer- cial fertilizers. Manure from half starved animals and those fed on low grade foods that merely serve to keep life in them, has very little value. ‘The quality of the manure made varies with the quality of the food fed. Rich food makes rich manure, and vice versa. The dried excrement of horses and cattle is nearly one-half the amount of the dry food consumed. One hundred pounds of dry matter in the food consumed by horses will make 210 pounds of manure, containing 77.5 pounds of moisture. Add to this the weight of the bedding, about six and one-half pounds per day, in order to get the total amount of the manure. It has been estimated that a well fed work horse will produce 50 pounds of manure per day, or six and a half tons per year, that can be saved. The manure of cows and neat cattle will contain on an average 87.5 per cent. of water. A steer, weithing 1,000 pounds and con- 56—Crop GROWING AND Crop FEEDING suming 27 pounds of dry matter per day, would produce about 20 tons of manure a year. A sheep will produce about three-fourths of a ton of manure yearly, and a pig from two to three tons. The following table gives the analysis of the various manures and their value per ton: Water Nitrogen Phos.

The urine is the most valuable part of the excrement of animals. The solid manure contains the undigested part of the food, and matter that is in a more or less insoluble state, while the urine contains the matters that have been fully digested and which are in a soluble condition. The composition of the urine, like that of the solid portion, varies with the age of the animals and the quality of the food consumed. There is a far higher percentage of nitro- gen in the urine and less phosphoric acid. In fact, the urine of horses and cattle contains hardly any at all. But it abounds in potash and soda. It is always best to use it mixed with the solid manure, which contains phosphates. Water that has leached from a pile of mixed manure is always a better fertil- izer than urine alone, as it has taken up the phosphates with the other con- stituents. As we have said, the composition of the manure depends largely on the kind of food used. If the food is of a nitrogenous nature and is easily digested, the nitrogen in the urine will greatly predominate; but if the food is imperfectly digested, the larger percentage may be in the solid dung. A horse fed on poor hay will show more nitrogen in the dung than in the urine. But a small portion of the nitrogen, phosphoric acid and potash supplied in the food is assimilated and retained in the animal body. Hence the value of the manure depends very largely on the nitrogen content of the food and its richness in the other forms of plant food. With animals which have com- pleted their growth and made their bony skeleton, and which are simply hold- ing their own as regards weight, neither losing nor gaining, the manurial con- stituents of the food are practically all returned in the manure. Figuring SouRCES OF FERTILIZING MATERIALS—57? from this base, it has been shown that the manure from feeding a ton of wheat bran will have a value of $12.50, and fed to milch cows will have 75 per cent. of this value. While no such value is ever recovered, even with the best treat- ment of the manure, these figures show the importance of the best care, since the most costly part, the nitrogen, gets away so rapidly. The chief value of the home-made manure is in the nitrogen it contains, and in the capacity it has for the nitrification of its organic matter in the soil. It is this organic matter in the stable and barnyard manure which gives it its chief advantage over the commercial fertilizers. We can get nitrogen in a far more available form in the fertilizers, but will lose the beneficial mechanical effect of the organic matter in the manure. Still, although admitting the great value of the home-made manure as a source of nitrogen, and the importance of saving it in the best manner, I have long been of the opinion that there is: too much of a disposition on the part of some writers to make a sort of fetich of a manure heap, and to advise the application of more labor than the manure is worth to the piling, turning and composting of manure. The manure of the farm, while a valuable thing, and an article not to be wasted, has not a value that will repay*the putting of the amount of labor on it which some ad- vise. Take care of the manure, and get it as soon as possible, out on the land where plants are waiting to use it. Ona farm on which a proper rotation is _ practiced there is always a place to spread the manure. In the North, where it is impracticable to haul out the manure during the winter months, the best way to save it is to haye all animals in box stalls, or in covered barnyards, with plenty of litter, allow the manure to be packed down under foot, and let it remain undisturbed. In this condition it will not heat seriously and will lose less than in any other way. But, by all means, abandon the silly practice of throwing it out the stable windows, in piles, to heat and wash away in the rain. The extent to which the keeping of live stock and the saving of manure is neglected in the South Atlantic Cotton States would be amazing to the farmers of the North and West, who have so long been brought up to consider the feeding of stock and the handling of manure a necessary part of farm life. Thousands of cotton farms in this section have no stock on them but the mules that till the crop, and in many cases even the provender for these is bought and hauled to the place. There is evidence in many sections, how- ever, of improvement in this respect, and these conditions are usually found among the tenant “croppers” rather than among the farm owners. Still, the great need of the South Atlantic States is live stock. It has been stated by competent authority that the States of North and South Carolina grow three bales of cotton for every cow kept, while Texas, which produces the largest 58—Crorp GROWING AND Crop FEEDING part of the cotton crop, raises three cows to every bale of cotton she produces. Until the farmers of the South Atlantic cotton country change all this and get to the same proportion between stock and cotton there will be no real and permanent advancement in the development of their agricultural capa- bilities. No matter how valuable and convenient the commercial fertilizers may be, nor how much they may accomplish for the improvement of the soil in the hands of the wise farmer, they will never, with the great mass of the farmers, avail as much for permanent improvement as home-made manures. The great evil connected with the failure to grow forage and feed live stock in the South, is the continuation of the ruinous credit system. If our farming was more diversified and systematic, and there was not that sole dependence on the cotton crop, which is still largely the case, notwithstanding the great improvement made in many places; there would be sources of in- come from the stock that would enable the farmer to get on a cash basis in his farming, and thus immensely reduce the cost of the cotton crop to the grower. Ina section where the most valuable forage crop is at the same time a soil improver, and where nature has been lavish in the great variety of food crops that can be produced for the feeding of cattle andthe accumulation of manure, the cities and towns are supplied with beef from the west simply because there are no cattle on the farms to make beef from. The cotton farmers are annually buying nitrogen in their fertilizers because they neglect the sources from which they could get nitrogen without money and without price; and not only get it free of cost but make a profit in the getting of it. Millions of dollars are spent in the cotton states of the Atlantic border for nitrogen, which, if spent for live stock and the growing of the cow pea, would remain to bless the land with fertility and swell the purse of the farmer. While an individual may here and there be able to show a profit in his crops grown without the aid of the domestic animals; the result on the community at large is poverty of soil and purse. Then, too, farm life without stock loses one of its chief attractions to the young, for boys, as a rule, are fond of ani- mals; and if we want to keep the boys on the farm and to have them devote their energies to the improvement of the land, we must make homes instead of mere cotton fields, and a farm without cattle and other stock is far less homelike than one on which due attention is paid to these sources of profit and pleasure. We do not blame a boy for wanting to get away from a farm where he has only a mule to drive and a pair of wheels to ride on, and the greatest difficulty we have in inducing young men to study scientific agricul- ture lies in the fact that they have never seen any real farming done at home, and they have come to consider the life of the farm hopeless; so the young blood of the South, more than of any other section, is rushing away from the SouRCES OF FERTILIZING MATERIALS—d9 farm to the factories and workshops, and the men who should be the means of building up the waste places are abandoning the farms to desolation and the negro. If this book is instrumental in any way in inducing some of these farmers to adopt a different method, it will be well worth all he labor that has been expended upon it. NO NEED FOR BUYING NITROGEN. While the saving and using of all the nitrogenous manures made on the farm is an important part of the farm economy, the farmer who farms intelli- gently and practices a proper rotation of crops, need never buy an ounce of nitrogen in any shape for the ordinary farm crops. In the case of the market gardener, on limited areas, and with crops of greater value, it is, of course, important to heavily fertilize his acres. But in grain and grass farming, the farmer who realizes what the legumes will do for him need never expend a penny for nitrogen, and in fact, can not only get all he needs without cost, but can make a profit in the getting of it. And here is the main use that the farmer has for the commercial fertilizers, to enable him better to practice the true method of acquiring the nitrogen that is so plentiful in the air, over every acre, in all localities. No part of the country has a monopoly of the erial nitrogen. The air is just as rich over the poorest acre in the land as over the most fertile, and the farmer on the poor farm can get it just as readily as the man whose acres are already supplied with it. While nitrogen is an essential thing to plant life, and crops cannot be grown without it, it is the only element of plant-food that we can get without buying, and the one that costs the most when we do buy it in fertilizer. Then, when we can, by a proper course of culture, get this costly article which is so much needed, and can put money in our pockets while getting it, is it not passing strange that farmers should spend money for it? LEGUMINOUS PLANTS THE TRUE SOURCE OF NITROGEN FOR THE FARMER For many years farmers knew that in some mysterious way clover and other plants of the pea family, did not only furnish forage for feeding animals, but that the land was better for having grown the crop. Only within the past few years, have scientists studied closely the way in which these plants help the soil, and even yet very little is accurately known of the exact way in which the work is done. For our present purpose, however, it is enough to know that all the legumes have the power, by means of little microscopic plants, which inhabit certain swellings or nodules on their roots, to get the 60—Crop GROWING AND CRroP FEEDING free nitrogen of the air combined and stored in the form of organic matter in the soil. We will not enter into a discussion of the exact way in which they do it; the fact is that no one knows just how it is done. But it is enough for the farmer to know that it is done, and that he can, by the growing of these plants, get a supply of material in the soil, that in its decay will give nitrogen to the succeeding crop in abundance. But the very plants that do this nitro- gen catching for him, are the greediest of consumers of the other two im- portant elements of plant-food needed in most soils, phosphorus and potash, While the careful saving and using of the farm yard manures is an important help in the getting of nitrogen in the soil, the manure is always in an insuffi- cient supply, and is poorer in the other elements than is desirable. Therefore, the most important elements which a farmer must buy in order to keep up the productivity of his soil, are phosphorus and potassium in some form. These are essential to the growth of all plants, and are especially serviceable in encouraging the growth of the legumes, and the enabling them to get more of the costly and fleeting nitrogen for us. The various experiment stations have done so much work in the study of the manurial requirements of plants, and the effects of fertilizers, that there has grown up an impression among farmers that for every crop planted, some complete mixture of fertilizers must be applied. There is no doubt that the annual application of commer- cial fertilizers will increase the crop usually grown; but true farming is the getting of good crops at the least margin of expense consistent with the keeping up and improving the condition of the soil. It is not merely growing big crops, but the most profitable crops, too. If a farmer spends $10 for a fertilizer that gives him $10 worth more corn, he is simply buying corn at the market price. He would better have left that $10 worth alone and bought it for less labor. | CHAPTER VII. PHOSPHORUS, ITS SOURCES AND USE IN PLANT FEEDING. The second important element in the nutrition of plants and the matur- ing of crops is phosphorus. This element, like the other elements which enter into the feeding of plants, is never used as a pare element, but always in the form of phosphoric acid. This is a highly oxidized compound of hy- drogen and phosphorus, and forms, with alkaline bases such as lime, etc., salts known as phosphates. The most commonly available form is:the phosphate of lime. This is a large constituent of the bones of all animals, and is found in nature in the phosphatic rocks and coprolites. In the basic process of steel making, large amounts of phosphates are separated from the iron ore and left in the furnace slag, and this slag is one of the important sources of phosphoric acid for fertilizing purposes. In many of the sea islands where there is a heavy rainfall, the guano deposits have been largely composed of the phosphate of lime, the nitrogen having been washed away. Large deposits ot phosphatic rock are found all along our South Atlantic coast, and in the Mississippi valley and elsewhere. The origin of these deposits has been a matter of much discussion among geologists. The idea generally prevails among most farmers that these are the petrified bones of extinct animals, but this is far from being correct, though there are certainly many fossil remains found associated with the phosphatic rocks. Phosphatic guano is certainly the remains of the ex- crement and food refuse of sea birds, and coprolites and phosphatic nodules are thought to be the remains of animal excrement. But, whatever their origin, the importance of the deposits has long been recognized; for the replenishing of our soils with phosphates is one of the greatest of the problems that confronts the cultivator, since in all cultivation, and in the raising of domestic animals, the phosphates are continually being removed from the farm. Unlike the nitrogen we cannot get phosphates.from the air, and there are but two ways in which the loss to the farm in phosphates carried off from it can be made good. We must either feed on the farm food grown elsewhere, or we must buy the phosphates when they are deficient. Inasmuch as the localities are few where the feeding of purchased food can be made'a profitable (61) 62—Crop GROWING AND Crop FEEDING part of the farm economy, the renewing of the phosphates in the soil becomes a very important matter. There has long been an impression among farmers that phosphoric acid from animal bones is more valuable than phosphoric acid from rock phosphates or other sources. But this is not the case. A superphosphate made from bones will contain some nitrogen, and hence, will have that additional value; but its phosphoric acid is not a whit different from the phosphoric acid from other sources. The only point of importance to the farmer is the percentage of the phosphoric acid-which is soluble in water, and is hence immediately available for plant feeding. In the natural state, the phosphoric acid of bones, rock or furnace slag is insoluble. Then if the rock is finely pulverized, and the bone (if finely pulverized), the bone will be the more quickly available of the two, because of the readiness with which it decays in the soil; and the fact that the raw bone carries with it a consider- able percentage of nitrogen, while the phosphatic acid rock has none of this. But when treated with sulphuric acid and made soluble, the acid of the rock is just the same as the acid of the bones treated in the same way. But the prejudice in favor of the bones is such that it. is a common practice among the manufacturers of fertilizers to call their articles bone phosphate, when, in fact, no bones have ever been used in its manufacture. The great source of the phosphates used in this country is the phosphatic rock mined from the land or dredged from the river beds in South Carolina. Large quantities are also mined in Florida, which are classified as “soft,” “rock,” “pebble” and “bowlder” phosphates. There are also “apatites” from Canada, and a very fine quality of phosphatic rock from Tennessee, and re- cently a deposit has been found in the Juniata valley in Pennsylvania. When treated with sulphuric acid to render them soluble these are known as acid phosphate, and this forms almost the entire source of the phosphorie acid used in the making of fertilizers, though some are still made from the refuse bone charcoal which has been used in the refining of sugar. A minor source, as we have said, is the slag from the manufacture of steel by the basic process. This is known as “basic slag,” “Thomas slag” and “odorless phosphate.” The quantity produced in this country of this last, is yet too small to have any great effect on the market. Much of the tankage from the Western slaughter houses has large percentages of bone associated with the nitrogenous matters, and this, too, is frequently treated with acid to render it soluble. Untreated tankage is more valuable for its nitrogen than its phos- phoric acid. Bones are also some times steamed, by which means a large part of the nitrogen is extracted, which has the effect of increasing the percentage of phosphoric acid in the product. Steamed bone may contain as much as 28 per cent. of phosphoric acid and very little, if any, nitrogen. It PHospuorvus, Its Sources AND UsE IN PLANT IEEDING—63 will, therefore, have a larger percentage of phosphoric acid than raw bone meal, but far less nitrogen; and if the phosphoric acid is what we are after, the steamed bone is better than the raw, and the absence of nitrogen should make it cheaper. But it must be remembered that the phosphoric acid is not in an immediately soluble condition, though through the rapid decay of the bone it may soon become so. The Florida soft phosphates are not available .n the manufeture of acid phosphates, and hence, many efforts have been made to get farmers to use them in an untreated state. An article called “Natural Plant Food,” was some time ago largely advertised. This consisted almost entirely of the Florida soft phosphates, with some insoluble potash, such as is found in the green sand marl of New Jersey. It has been found that on a soil abounding in humus, and in an acid condition, the pulverized phosphatic rock sold under the name of “floats” acts very well, especially on clover and other legumes, but that liming the soil, which helps the success of the clover, renders the phosphate less effective. In some stations the insoluble phosphoric acid is given no value whatever, while at other stations it is rated at 2 cts. per pound, with the soluble at four and a half cents. What we wish particularly to impress upon the farmer, is the fact that phosphoric acid from any source is identically the same thing, and the only question that concerns him is what percentage of the article is in a soluble state, for it is this which is to give him immediate results in the crop. BONE MEAL AS A SOURCE OF PHOSPHORIC ACID. We have stated that phosphoric acid is one and the same thing no matter from what source it comes, and that the only thing to regard is the percentage of soluble acid. On this point the investigations of the Massachusetts Exper- iment Station show the following conclusions: 1. The superior VALUE which has hitherto been accorded to undis- solved bone meal as a fertilizer is due solely to the nitrogen it contains. 2. Undissolved bone meal, as a phosphate fertilizer, is no more valuable than the raw mineral phosphates (floats). 3. Hereafter it must be classed with the latter, rather than with the high grade phosphates containing available phosphoric acid. 4. As a phosphate fertilizer it yields no better results than the mineral phosphates, whether tried alone or with superphosphate, on loams or sandy soils, on soils rich or poor in phosphoric acid, whether with grains or with turnips, mustard or other cruciferous plants ; either in the first or second crop. 5. The various kinds of bone meal show no essential difference in these results. In experiments made by Wagner at Darmstadt, Germany, the phos- 64—Crop GROWING AND Crop FEEDING phoric acid in the form of acid phosphate gave 100 pounds in the crop to every 59 pounds from the Thomas slag, and 8 pounds from the same quantity of bone meal, and in three years the results from the bone meal application were only 17 per cent of those from the acid phosphate. It has been argued by those who favor the use of bone meal that, while not so immediately availa- ble, the after results would more than make up for it. Wagner shows that even after three years it only reached to 17 per cent. of the crop produced at the same time from soluble phosphoric acid. ‘This is an important matter to the farmer, since bone meal is a far more costly article than superphosphate. Aside from the fact of the slow availability of the phosphorie acid in bone meal, there is the further fact that it is very hard to get a perfectly pure bone meal except in States where the inspection is very rigid. The writer once passed an establishment in a large Eastern seaboard city, where the sign announced “pure bone meal.” There was a “no admittance” sign at the door, but hearing machinery in operation I ventured to peep in. An Irishman who was tending a machine grinding oyster shells warned me to keep out, but I had seen all that I was after, and noted the place as one to avoid in buying bone. THOMAS SLAG, SLAG MEAL, BASIC SLAG AS A SOURCE OF PHOSPHORIC ACID. These names, and also the name “odorless phosphate” are applied to the phosphate obtained from the slag made in the process of making steel by what is known as the basic process. There is not enough of it made in this country for it to compete with the rock phosphates. The article is reduced to a fine powder and is not treated with acid. It contains usually about 20 per cent. of phosphoric acid in the form of phosphate of lime, or the same form in which it is found in the pulverized phosphate rock. Whether the phosphoric acid in this slag meal is any more readily available than that in the pulverized phosphate rock, or “floats,” is a matter not as yet well settled. In most of the country the rock phosphates are cheaper. MARLS AS A SOURCE OF PHOSPHORIC ACID. The name marl is applied to certain earthy deposits which are found along our Atlantic coast. These vary in composition from those consisting almost entirely of the carbonate of lime from the decomposition of marine shells to those like the green sand of new Jersey and the Virginia marls, some of which contain notable percentages of phosphoric acid and some pot- ash. Phosphatic marls have phosphoric acid in the form of the phos- PuHospHorus, Its Sourcrs aNpD UsrE IN PiLant Frepine—65 phate of lime as it exists in the phosphatic rocks, and it is in a similarly insoluble state, while the potash is in the form of a mineral known as glau- conite, and is also insoluble at once. Mr. Ruffin, of Virginia, whose book on calcareous manures was for many years the standard authority on the sub- ject in this country, attributed the effects of marl, which he used largely on his lands in Southeastern Virginia, to the lime it contained. But it has been shown that in every instance the most valuable marls are those which contain the largest percentages of phosphoric acid, though shell marls are also valu- able as a source of lime for certain soils. PHOSPHATIC GUANO. After the exhaustion of the rich deposits of guano in the Peruvian islands, large quantities of phosphatic guano were brought from islands in the Carribean Sea, where the soluble nitrogen had been washed out by rains, leay- ing only the insoluble phosphate of lime. These guanos are used to a con- siderable extent in a pulverized state, and answer about the same purpose as the Florida soft phosphates of recent days. Most of these guanos are not adapted to the making of acid phosphate, and they are now little used since the discovery of the great deposits of phosphatic rock in North and South Carolina, Florida and Tennessee. THE GREAT PHOSPHATE ROCK DEPOSITS The phosphatic rock that has entered more largely into the manufacture of acid phosphate is the South Carolina rock. This is pulverized and treated with sulphuric acid, and the result is the article called acid phosphate, which contains usually about 12 to 13 per cent. of soluble phosphoric acid, a smaller percentage of what is called “reverted” phosphoric acid, or acid not soluble at once in water, but soluble in citrates. The soluble and the reverted phos- phoric acid are added to make what is called the “available” phosphoric acid. Then there will always be a small portion of the phosphoric acid which is in- soluble. Some Station chemists assign no value to this in their valuations of fertilizers, while others value it at 2 cents per pound when the available is rated at 4 cents. This is the fairer valuation, since there is evidence that it does finally become available in the soil, just as the pulverized rock does. Large deposits of phosphatic rock are found also in Florida, much of which is known as “soft” phosphate, and is not available for dissolving with sulphuric acid, and strenuous efforts have been made to get it into use under the name “Natural Plant Food.” It has value, if one has time to wait on it. Another important deposit of phosphate rock has more recently been dis- 66—CropP GROWING AND Crop FEEDING covered in Central Tennessee. ‘This has a high percentage of phosphate of lime, and will become the most important point from which to get phosphoric acid in the Central Western States. Another deposit has been discovered in the Juniata Valley of Pennsylvania, but whether it will assume any com- mercial importance is not yet known. Hard phosphate rock, which will yield on dissolving with sulphuric acid a good, drillable acid phosphate will always be of more agricultural value than those not adapted to this purpose. While phosphoric acid may exist in the form of iron phosphate and of aluminum phosphate, the only form in which it is available in the manu- facture of commercial fertilizers is the phosphate of lime. This is the form in which it is found in phosphatic rock and in animal bones, and hence manu- facturers, whose product does not contain a solitary animal bone, are very fond of printing on their bags the statement that the percentage of phosphoric acid in it’is “equal to bone phosphate ;” thus leading the farmer to imagine that there are bones used in it, as they think that farmers value phosphoric acid from bones more highly than the same thing from some other source. I cannot too often repeat that it is the percentage of availability that the farmer is concerned with, and not whether it came from bones or rock. All untreated phosphates are insoluble in water, and untreated bone will become available more readily than untreated rock phos- phate, because it decays more readily, provided both are in an equally finely pulverized state. Many farmers have declared that they get as good results from the pulverized phosphates as from the acid phosphate, and in certain soils this may be the case, for the character of the soil has much to do with the rate in which the phosphoric acid in an untreated phosphate becomes available. In a soil abounding in humus, or vegetable decay, the phosphates will become soluble more readily than in a heavy, clay soil deficient in organic decay. In the porous soil, filled with humus, the oxidizing influences of the air have free access, and decay proceeds more rapidly, while the acidity of such soils also favors the change. For general purposes it is far better, how- ever, to use the acid phosphate than the lower priced pulverized rock or the iron phosphate. Professor Voorhees well says that, “In any case, animal bone, or finely ground mineral phosphates, cannot be depended upon to fully meet the needs of quick growing crops for phosphoric acid, but may answer an excellent purpose where the object is to gradually improve the soil in its content of this constituent, as well as to supply such crops as are continuous, or that grow through long periods, as, for example, meadows, pastures, and orchard and vineyard crops.” That is to say, that where you can afford to wait and where you want long-continued, slow availability, it may pay to use the more slowly available forms of phosphoric acid, but where you want the PuHospuHorus, Its SourcEs AND USE IN PLANT FEEDING—67 effect on the immediate annual crop you had better get the dissolved rock or acid phosphate. With most farmers, the question of immediate returns for the expenditure is the most important point. SOME ERRONEOUS POPULAR NAMES. In some parts of the country farmers call all commercial fertilizers “phosphate.” This is an error which all should rid themselves of as quickly as possible. The term phosphate is applicable only to compounds of phos- phoric acid and a base, making what is called a salt. Thus the phosphate of lime is a salt composed of a certain number of parts of lime with phosphoric acid. A commercial fertilizer in which the phosphoric acid is only one of the constituents cannot correctly be called a phosphate. It is simply a fertilizing mixture in which phosphoric acid is one of the constituents. The proper term to apply to all mixed goods is commercial fertilizer. Then, too, the popular name “acid phosphate” as applied to the dissolved phosphate rock is not strictly correct. Phosphate is the original condition in which the phosphoric acid is found in the rock. When dissolved in sulphuric acid it becomes a superphosphate. But the term “acid phosphate” has be- come so fixed in popular use that it answers all purposes, and suits our Ameri- can liking for brevity better than the longer word, superphosphate. Super- phosphates, whether made from rock, bones or bone charcoal, are identical, varying only in the percentage of phosphoric acid with the amount in the article from which they are made. Hence a superphosphate made from bones will have a higher percentage of phosphoric acid than one from rock, but one per cent. in the one is just as good as one per cent. in the other. Acid phos- phate is always better when freshly made than after being stored for a long time, since there is a tendency to reversion to a less soluble form in long standing, and there is a decrease of the soluble and an increase of the form soluble only in ammonium citrate. Acid phosphate, then, which has been kept over a season, is less immediately available than a freshly made article. This takes place more readily in superphosphates made from the mineral phosphates than in those made from bones or bone charcoal. Superphos- phates made from bone and bone charcoal are more uniform than those from mineral phosphates, and their phosphoric acid is nearly all soluble, while those from mineral phosphates may run all the way from 12 to 14 per cent. in the South Carolina, to 16 or even 18 per cent. in the Tennessee. Super- phosphates from raw animal bone usually have about 12 per cent, available phosphoric acid, and about 5 per cent. insoluble, but having also a percentage of ammonia, they have a higher value commercially than the dissolved rock, but their agricultural value may be no higher. 68—Crop GROWING AND Crop FEEDING The writer has frequent inquiries from farmers who are anxious to know whether the free sulphuric acid that they are told remains in the acid phos- phate from the rock, will be injurious. The fact is there is seldom, if ever, any such acid in a well-made superphosphate, and even if there was it would at once seek some base in the soil and be changed to a neutral salt, either the sulphate of lime, potash or magnesia, according as one or the other may be present in the soil. It has been found that where superphosphates have long been used freely the phosphoric acid will accumulate in the soil to such an extent that further applications have no effect. This has been the case in a large section of Eastern North Carolina, where the farmers say that they no longer get any returns from the application of phosphates to their cotton crop. The fact is that the soil holds on to phosphoric acid longer than anything else in the way of plant food, and does not allow it to leach away as the nitrogen is apt to do, but keeps it there till the crops call for it. Hence it is easy to see that in making liberal applications of phosphates, whether merely pulverized bone or rock or dissolved phosphate, we are in no danger of serious loss, but can depend on any surplus staying there till wanted by the crops. Professor Voorhees well says, “The real object of making it soluble is to enable its better distribution. If it were possible to as cheaply prepare the dicalcic (or reverted) form as the soluble, it would, perhaps, be quite as useful from the standpoint of availability. After the soluble is distributed in the soil, it is fixed there by combining with the lime and other minerals present.” It is thought that it at once assumes the reverted form, and that in the presence of an abundance of lime may even become insoluble. The solubility of the phosphoric acid lasts much longer in a light soil deficient in organic matter, but even there it is fixed rapidly enough to prevent serious loss. Chemical analysis of the drainage waters seldom shows any loss of phosphoric acid. THE VALUE OF INSOLUBLE PHOSPHATES. In the valuation of commercial fertilizers, as we have noted, some of the Experiment Stations place no commercial value on the insoluble phosphoric acid in a fertilizer. We have long been satisfied from our own experience that this is an error, at least so far as the agricultural and crops-producing value of the insoluble phosphate is concerned. Years ago, in farming on a large scale, we found that we did get the happiest results from the use of the phosphatic guanos from the Carribean islands in which the phosphoric acid, was all insoluble. True, we did not get the same immediate results as fromthe use of the dissolved acid phosphate, but the final result was as good and more lasting, and when these insoluble forms of phosphoric acid were PuHospHorvs, Its SourcES AND USE IN PLANT FEEDING—69 used on the wheat crop, we never failed to get large returns in the luxuriant stands of clover that followed, though the effect on the wheat crop direct was not so apparent as when the acid phosphate was used. But we invariably had more difficulty in getting a good stand of clover after the use of the acid phos- phate than we did after the use of the insoluble phosphoric acid. In our case stock and stock food was the chief interest, and the wheat was only regarded as a means for paying the expense of getting the land in clover. Where im- mediate results only are sought it may be best to use the dissolved phosphate, but where final results in the clover and grass are of more importance, then it will be far cheaper and perhaps better to use simply the pulverized rock, or what is known as “floats.” As we have often said, where one can afford to wait for the results he can get them with less expenditure of money in the use of pulverized rock than in the dissolved article. ‘This experience has been verified by some experiments made at the Maryland Agricultural Experiment Station and published in a recent bulletin of that Station. They state that the best results were obtained, in the long run at least, from the use of the insoluble phosphates. Not having this bulletin at hand we cannot quote from it direct, but believe that we have given the sum of their results. The fact is that no chemist can discover just what is taking place in the soil, even with what may be put there in what he calls a perfectly soluble state. The soil is a wonderful laboratory, in which the forces of nature are always at work, making new combinations and bringing about changes in what we put there. The carbonic acid of the rain water is nature’s great breaker up of combinations and former of new ones, and what exists in the soil in one state today may be in a very different oné tomorrow. It is always safe, then, for the farmer to question his soil and to accept the results it gives him, for he ean find thus, for himself, things that no chemist can discover. In certain sections of Eastern North Carolina observant farmers have long since found that they got no results for the use of phosphoric acid in any form, but that nitrogen and potash always gave them good results. Subsequent investiga- tions by the Department of Agriculture have demonstrated that these farmers are right, and that on their lands the chief need is for nitrogen and potash. Then, since by good farming with the legumes they can get all the nitrogen they need, the farmers on lands where phosphatic marls and rocks are found, are in that happy condition where they need to purchase but a single form of plant food in order to make and keep their lands perennially productive. There may be other sections North and South, where similar conditions pre- vail, and this makes it all the more important that farmers should experiment to determine the manurial needs of their soils. How this is done we have tried to explain elsewhere. CHAPTER VIII POTASH. Potash is the result of the oxidation of the element potassium, which is one of the metallic elements. In former days all the potash available for manurial purposes was that which is contained in the farm manures and in wood ashes. These are still valuable sources so far as they go, but they are totally insufficient for the demands of modern agriculture. It is a wonderful fact in the economy of nature that stores are provided to come into use as the demand for them arises. The vast deposits of coal were not discovered so long as the forest met all the requirements of man for fuel, but as the de- mand came the supply was at hand to meet it. Just so with the potash. With the great call for this material for the feeding of plants on our long cultivated soils, there was discovered a vast deposit of potash in the salt mines of Germany, in the form of sulphates and chlorides of potash. These mines are now the great source of the world’s supply of potash, and it has been found that the deposit extends over a much larger area there than was formerly sup- posed, and that the supply is practically inexhaustible. Doubtless if the German supply should fail there will be discovered other deposits, to redeem the promise to mankind that seed time and harvest shall not fail. POTASH AN ESSENTIAL PLANT FOOD. Experiments, carefully conducted, have shown that potash is one of the things which plants cannot grow without. In a soil or a solution entirely free from potash a seed will germinate and grow to the extent of the potash stored in the seed itself, but when that is used up the plant perishes. In the cultivation of farm crops it has been found that potash is more slowly ex- hausted from the soil than other forms of plant food, since its office mainly consists in the building up of the woody structure and cellular parts of the plant, and hence is found in the straw, corn stalks and other materials that (70) PotasH—‘71 ‘usually are kept on the farm, and returned in the manure; and not because it leaches away from the soil less rapidly than phosphoric acid. The great office of potash in the plant seems to be the structure of starch, since it is found that while all the conditions needed for the assimilation of carbon from the air (the process through which starch is formed), may be present, the starch is not formed without the presence of potash in sufficient quantity. Now, as all woody structure is formed from the starch, it is evident that potash is an important matter in the building up of the plant. Plants like potatoes and corn, which make large surplus quantities of starch to store away in tubers and grain, require large percentages of potash in their food. SOILS WHICH NEED POTASH MOST. Light, sandy soils near the coast are more apt to be deficient in potash than the heavy clays, especially the clays that are the result of the decomposi- tion of granitic rocks, which naturally contain a larger percentage of potash. But even in some of these soils the application of potash may be found profit- able, because the potash may be, and commonly is, in the form of an insoluble silicate, and this becomes very slowly available to plants through the action of the carbonic acid in the rain water. Black, peaty soils, resulting from the decomposition of vegetable matter, are very commonly deficient in potash, and it is a common remark on the South Atlantic coast that a certain soil will grow upland rice, but will not make a crop of Indian corn. This is mainly because of the deficiency of mineral matters, chiefly of potash. It is a com- mon and almost universal practice among the manufacturers of fertilizers to make the phosphoric acid much larger in proportion than the potash, and it has been shown by experiment that the average commercial fertilizer has, as a rule, too small a percentage of potash in proportion to the nitrogen and phosphoric acid. The plants, like peas and clover, which give us nitrogen free of cost, are great consumers of phosphates and potash, and they can do far more of their important work if well supplied with the mineral elements of plant food. The average complete fertilizer mixture contains not more than 1 to 2 per cent. of potash, while for tobacco, potatoes, and corn and some other crops the potash on light soils should be as high as 10 per cent. for the best results. Therefore, it is important for the progressive farmer to make his own fertilizing mixtures, so that he can vary the proportions to suit the different crops grown; and if he practices the best rotation, he will find little use for the complete fertilizers, will finally buy nothing but phosphoric acid and potash, and will use these freely for the purpose of getting more of the nitrogen fixed in his soil. ¥2—Crop GROWING AND Crop FEEDING WHAT IS THE BEST FORM OF POTASH ? As we have said, the potash mined in Germany exists in the forms of sulphates, chlorides and carbonates. There is little difference in the rate of availability to the plant of any of these forms, but the effect of the particular form on the different crops is an important matter. It has been found that while the muriate (or chloride) of potash will produce a heavy crop of tobac- co, it seriously impairs the quality of the leaf, and hence in a tobacco fertilizer it is important to use the sulphate, which is free from chlorides. In some sections it has been found that the Irish potato crop is damaged in quality by the use of muriate, while in other sections the muriate is used exclusively on this crop. The nature of the soil seems to have a great deal to-do with the form in which potash is of use to the Irish potato. In the great early-potato growing section of the South Atlantic coast, the muriate has been found to give the finest crop; while in the North and on a heavier soil, the sulphate is of importance in giving quality to the product. On a clay soil and in a Northern climate we should use the sulphate for potatoes. Crops that have sugar as an important constituent are always more favorably affected by the sulphate than the muriate. Sweet potatoes, sugar beets, strawberries, toma- toes and such should always have their potash in the form of a sulphate free from chlorides. Indian corn and grasses, wheat and oats, are indifferent to the form in which the potash is furnished. CRUDE POTASH SALTS. As mined in Germany there are two principal forms of the salts in a crude state. These are kainit and sylvanite. There are other forms, but these are about the only ones exported, and by far the larger part of the crude salts that come to this country are in the form of kainit. While the potash in kainit is in the form of a sulphate, it is mixed with such a large percentage of chloride of sodium (common salt) that its action is the same as the chloride, or muriate. Containing so low a percentage of potash, generally a little over 12 per cent., it is a costly form in which to buy potash at any dis- tance from the port of entry, since the freighting of so large a proportion of useless material rapidly runs up the cost of the potash to the farmer, which is the only thing in it which is of any great importance to him. It is also dangerous to use in large quantities in immediate contact with seed, or young plant roots, because of the salt it contains. Some time ago a farmer in the tobacco section of North Carolina wrote to me that he had bad success with the home mixing of fertilizers from a formula we gave him, and that the PorasH—73 quality of the tobacco was very poor. We asked him to send a copy of the bill of materials he had bought. He purchased them from a large manufac- turer of fertilizers, and it was evident, as soon as we saw the bill, that he had been imposed upon purposely in order to discredit the formula. I prescribed sulphate of potash in the mixture, and he ordered it. On the bill was © charged “sulphate of potash,” and then added, in small letters, “low grade kainit.” The cause of the poor quality of his tobacco was evident and we wrote to him that he had simply been cheated, as he should have had the high grade sulphate free from chlorides, and it was evident that the fertilizer man was after killing his home mixing. MANUFACTURED POTASH SALTS. These are products which have been treated to remove the excess of other constituents and to concentrate the potash. The most common form and the form most generally used in this country is the muriate (or chloride) of pot- ash. It usually contains about 50 per cent. of actual potash. Dealers frequent- ly confuse unlearned buyers by giving on their bags the percentage of muriate instead of the percentage of actual potash. Thus they will say, “muriate of potash, 80 per cent.” and lead the farmer to believe that there is 80 per cent. of potash. If you get an article with such a percentage stated, it simply means that it has that much of the muriate, and you can tell how much potash it has by multiplying the percentage of muriate by the fraction 0.632. Thus a bag marked muriate of potash 80 per cent., would have 50.56 per cent. of potash. In the same way the dealers will mark the sulphate of potash (the high grade) 98 per cent. sulphate of potash, and you can find the actual potash by multiplying this by the fraction 0.54, so that a bag having 98 per cent. of sulphate of potash will contain 52.92 per cent. of actual potash. As we have said, the sulphate is important for some crops for which the muriate is not well adapted, but its cost is greater than that of the muriate, and where the muriate is adapted to the crop it is always the most economical to use. The higher cost of the sulphate leads manufacturers of fertilizers to use the muriate where the sulphate should be used. One of the largest tobacco growers in North Carolina told the writer that he sent a formula to a large manufacturer in which he specified sulphate of potash. They agreed to make it by his formula, and when the goods arrived he sent a sample to the State chemist for analysis, and this showed that the muriate had been used instead of the sulphate. He therefore very properly refused to receive the fertilizer. Tobacco growers who buy ready mixed fertilizers cannot be too careful as to the source of the potash in them. There is another form of manufactured 74—-Crop GROWING AND Crop FEEDING potash called “ double manure salts,” or the double sulphate of potash and magnesia. This is a lower grade, and contains from 23 to 26 per cent. of potash. From the lower percentage of potash this, like kainit, is more costly _so far as the actual potash is concerned, and it is always more economical, especially where the goods are to be transported far from the port of entry, to buy the most concentrated article and thus avoid the freighting of useless matter. CAPACITY OF THE SOIL FOR ABSORBING POTASH. In some instances, near the coast, it is found that kainit is the cheaper form in which to buy potash. But to get the amount of potash needed by the early potato crop, for instance, would require an application that would be certain to be injurious from the amount of sodium chloride if directly applied to the crop. Fortunately it has been found that while the soil will release the chloride of sodium and allow it to leach away, it will hold on to the potash that was associated with it. Therefore, it has become the practice with a few growers near the coast to apply a heavy dressing of kainit in the fall, to the land they intend planting in potatoes in the spring. The imjurious chloride is leached out of the sandy soil during the winter, while the potash remains. It also seems probable that the chloride in the leaching may render soluble other matters in the soil that may be of use, and thus help the crop. But this very fact may be a disadvantage, since there may be formed soluble chlorides of lime, and the heavy application of kainit may result in the ex- haustion of the lime in the soil. But where this practice is followed, the abundance of marine shells at hand will soon remedy this, if used on the soil after burning. ‘There are few localities, however, where kainit is the cheapest form of potash. The application of potash should in any event, be immedi- ately worked into the soil, so that it may be equally diffused in the soil and not fixed merely at the surface. DANGERS FROM POTASH. The general opinion is that kainit is especially dangerous in contact with seeds or young plant roots, by reason of the large percentage of salt which it contains. This is true, but in our own experiments we have found that the muriate is far more damaging to germination of seeds with which it comes in contact, than kainit is. Carefully conducted experiments have shown that even when covered with an inch of soil, seeds placed above the muriate were seriously damaged. In fact, no fertilizer containing a large percentage of potash should be used in direct contact with the seed; and it is far better that PotTasH—75 both the potash and the phosphates should be applied broadcast, and some time in advance of the planting of the crops, so that they may become fixed and as- similated in the soil an? their caustic effects prevented. Growers of frame lettuce in Eastern North Carolina know that in their sandy soil the crop needs a liberal supply of potash, and they usually give it liberally. A lettuce grower some time since sent me in the early fall some of his plants, which had the edges of the leaves turning red and evidently dying. He wanted to know the reason. Examination showed no insect or fungus attack, but the roots were evidently injured. The plants were set in a frame here and at once grew off and made fine heads. I found that the grower had applied a heavy dress- ing of muriate of potash in the fertilizer used on the frames, and this was doubtless the cause ; for on taking up all the plants and re-setting the frames, after several good rains, he had no further trouble. Wheat growers commonly drill their seed with the fertilizer, and this may do where a very small per- centage of potash is used, and the quantity is far less than that used by the truck growers. POTASH IN WASTE PRODUCTS. Farmers in the tobacco manufacturing sections, and tobacco growers, should understand the value of tobacco waste. The stems from which the tobacco leaves are stripped on the plantations are a valuable source, not only of potash, but of phosphoric acid and nitrogen as well. ‘The stems from the stemming houses are still more valuable, and the dust from the factories where smoking tobacco is made is in a form that is very much more readily taken by plants than the stems. The field stalks of tobacco contain 3.71 per cent. nitrogen, 5.02 per cent. of potash and 0.65 per cent. of phosphoric acid. The stems from the stemmeries contain 2.35 per cent. of nitrogen, 8.20 per cent. of potash and 0.70 per cent. of phosphoric acid. So that with the ex- ception of phosphoric acid they form a complete fertilizer of high grade. But of course they cannot be compared with a soluble fertilizer of similar analysis, since before the nitrogen and other things can become available to plants the material must be completely decayed in the soil. Hence the finely divided dust from the smoking tobacco factories will probably be the more quickly available. Where these materials can be bought cheaply, the farmer may be able to get potash in a cheaper form than any other. We have at hand no analysis of the tobacco dust, and it doubtless varies a great deal owing to the amount of sand and other impurities in it. The percentage of potash may run as high as ten per cent., and the nitrogen as high as in most of the fertilizer mixtures. Part of the nitrogen in tobacco exists as a nitrate and is %6—Crop GROWING AND Crop FEEDING immediately available to plants. The remainder is organic nitrogen, which must go through the process of nitrification in the soil to become available to plants. Where the farmer is so situated as to be able to get these tobacco wastes, he should by all means avail himself of them, since they are rich in plant food and contain no deleterious matters. We have seen tobacco dust spread an inch thick on a lawn with the finest results. A ton of tobacco stems of good quality contains nitrogen equivalent to 500 pounds of nitrate of soda, and potash equal to 200 pounds of high grade sulphate of potash. Since these tobacco wastes can often be bought near the factories for $3 to $5 per ton it is evident that they are a very cheap source of nitrogen and potash. COTTON SEED HULL ASHES. The oil mills engaged in the manufacture of cotton seed oil in the Southern States use the hulls from the seeds largely as a fuel in their fur- naces. The ashes resulting from this burning contain a large percentage of potash, and a fair percentage of phosphoric acid, with very little lime. Ordinary wood ashes contain so large a percentage of lime that they are not available for mixing in fertilizers, since the lime will have a tendency to drive off ammonia and revert the phosphoric acid. While cotton seed hull ashes are rich in potash, they vary greatly in the actual percentage of potash and their value cannot be predicted without an actual analysis of the sample. They contain from 20 to 24 per cent. of potash, nearly 9 per cent. of phos- phoric acid, 9 per cent. of lime and 10 per cent. of magnesia. These ashes are an excellent source of potash and phosphoric acid, and the fact that they are not so rich in lime as ashes from the hard-woods is an advantage, and allows them to be used in compounding a fertilizer mixture where wood ashes would be inadmissable. GREEN SAND MARL. The green sand marls of New Jersey and Southeast Virginia contain a large percentage of potash, as well as a smaller percentage of phosphoric acid. But all these are in a form very slowly available. Their slow availability ren- ders the marl applications lasting in effect, and as the green sand marl can be applied in very large quantities without injurious effects, its value as a me- chanical amendment to the soil is very considerable. Marl has had a great ef- fect on the lands of a section of New Jersey, and also in Southeast Virginia. A farm in Virginia which had an application of 400 bushels per acre 40 years ago was made permanently productive, and since then a further application of marl has not seemed to have any effect. CHAPTER IX. LIME AND LIMING LAND. The substances of which we have been treating in the past three chapters, nitrogen, phosphoric acid and potash, are direct fertilizers, or plant foods. We come now to the consideration of the forms which are most useful as re- agents, or, as we may say, stimulants to the productive capacity of the soil. While it is true that calcium of which lime is the oxide when freshly made, is one of the elements essential to plant growth, it is usually found in all cultivated soils in almost inexhaustible quantities for all the purposes of direct plant feeding. Yet an application of freshly slaked quick lime (or hydrate of calcium), will often have a marked effect on the productiveness of the soil, through its action in releasing other forms of plant food, particu- larly potash, from the insoluble silicates in which it occurs in the soil. Lime is also important in a soil abounding in organic matter, as it cor- rects the acidity of such soils, and enables the nitrifying microbes to thrive _ and do their work in bringing the nitrogen of the organic matter into the available form of a nitrate. Hence the old proverb that “Lime enriches the father and impoverishes the son,” for it enables us to get at the plant food in the soil, and if used with the notion that it is simply a manure we may soon find that its use has tended to exhaustion. Judiciously used, however, there is nothing that is a greater aid in the development of the farm. Lime also has an important mechanical effect on soils. It renders a heavy clay soil more friable by gathering it into small lumps, or flocculating it, as it is called. On a sandy soil it sinks and forms a compact layer below the plow, and thus renders the soil less leachy. But in many sections where there is a fertile soil well supplied with humus, the application of lime has at first pro- duced such marked results that the farmers have jumped to the conclusion that lime is all they need to keep up the productiveness of their lands. After a while they find that the lime has less and less effect, and they are compelled to resort to commercial fertilizers for the production of crops. We recently (77) "8—Crop GROWING AND Crop FEEDING. had a letter from an old and observant farmer in one of th most prosperous agricultural sections of the State of Maryland, who deplored the fact that his neighbors had used lime to such an extent that their lands were less pro- ductive than formerly. He said that for over thirty years he had used noth- ing on his farm but acid phosphate and clover, with an occasional dressing of a moderate amount of lime to preserve the sweetness of the soil and to enable it to grow large crops of clover. The result was that he made 40 bushels of wheat per acre where his neighbors grew less than formerly. Now, in his application of acid phosphate every third year he applied in it 40 per cent. of the sulphate of lime, and adding a small dressing of freshly slaked lime every sixth year, he kept releasing the potash in his soil, and hence needed only the phosphoric acid in his fertilizer. His red clay soil contains an almost inexhaustible deposit of potash as an insoluble silicate, and the lime gradually gives him the use of some of this. How long he can keep up the productiveness of his land without adding potash will, of course, depend on the amount his soil contains. The wise farmer will, however, watch closely and stand ready to supply the deficiency as it occurs, but will not waste money in the purchase of what he does not at present need. Limestone, from which lime is made, is an impure carbonate of lime, in many instances being mixed with a large percentage of magnesia, making what is called dolomite, or magnesian, limestone. As the magnesia is a use- ful plant food this is not a bad mixture for most soils. Where pure lime is wanted the purer the stone, even till it becomes marble, the better. Oyster shells are used as a source of lime in the coast region, and they are a pure car- bonate of lime, and when free from earthy impurities, make a very pure lime. In some parts of the South lime is burned from the fossil shell rock and contains a small percentage of phosphoric acid. One of the greatest of the values of lime to the farmer is in enabling his soil to grow clover. It is found that the constant growing of clover and the accumulation of organic matter in the soil tends to create an acid condition. Under this condition, the microbes that enable the clover plant to collect nitrogen do not thrive, and the soil microbes that carry on the work of transforming the organic nitrogen into nitrate will not exist. The farmer finds that he can no longer grow clover with any success, for the land is “clover sick.” This is generally the result of an acid condition of the soil. Lime will correct this condition and will usually cause the clover to grow luxuriantly. Most of the legumes are lime-loving plants. The great success of alfalfa in the arid regions of the West is largely due to the fact that the lime has not been washed out of the soil. In the Eastern States no great success with alfalfa has ever been had except from liming it, We visited a year or so ago the grass experiment farm of Peter LIME AND Liming LAND—79 Henderson & Co., at Hackensack, N. J. We were shown there a luxuriant plat of alfalfa, and were told that the year before it had been .very feeble, but in hauling lime to another part of the farm a little shook from the wagon on the corner of the alfalfa patch. At once that part assumed a stronger growth, and noting this, they applied a dressing of lime to the whole plat with the finest results. Shortly after this I visited the farm of a wealthy gentleman in North Carolina, who is interested in the dairy, and was trying to grow alfalfa. We advised him to give it a coat of lime, which was done. We passed the field but a few days ago and noted from the train that it was the most luxuriant growth of alfalfa we have ever seen in the East. The lime is not only to some extent direct food for the alfalfa, but it brings about changes in other matters that favor its growth. One of these changes is one of the most recent discoveries in science. We have seen that all green plants get their carbon from the air through the assimilative action of their green matter. Fungus plants have no green matter and hence, as a rule, are de- pendent on what green leaved plants have assimilated. But these microscopic plants in the soil, which carry on the work of changing the organic nitrogen into nitrates, though they are members of the great fungus class, have a power that no green plant is known to possess. They can get the carbon for their growth from mineral combinations like the carbonate of lime. Here, then, is another reason why the application of lime to a soil abounding in organic matter favors the nitrification, or formation of nitrates, for the use of green plants which must get their nitrogen from the soil. Lime, to have its best effect, should be well burned, and slaked with water to a powder before applying it to the soil. If allowed to he and get air slaked it is far less effective, since it gets, through the action of the car- bonic acid in the air, into an insoluble carbonate, or returns almost to the con- dition in which pulverized limestone would have been. Stone lime slaked with water till it falls, should make three bushels of slaked lime for every bushel of fresh lumps. Oyster shell lime will slake two bushels for one. There has of late been quite a change in the ideas of thinkers in regard to the quantity of lime that should be used. Formerly it was the practice to apply lime in large quantities and at long intervals. In recent years it has been shown experimentally that a small application, frequently repeated, is far better than the heavy application, so that now it is seldom that more than 20 bushels per acre are used by the best farmers, and some even contend for a smaller application than this. With a short rotation of three or four years, in which there are frequent crops of legumes grown, the repeated application of small doses of lime every four or five years has been found to produce bet- ter results than twice the amount at a longer interval. 80—Crop GROWING AND Crop FEEDING Experiments that have been long and carefully conducted by the Rhode Island Agricultural Experiment Station, have shown that the sweetening of an acid soil by the application of lime is not always an advantage, since there are some plants that seem to prefer the acid soil, or rather some that are more exempt from disease in such a soil. On the Irish potato crop, for instance, it was found that liming brought about conditions that were favorable to the fungus that causes scab in the potato, and while the resulting crop may be larger the market value was reduced by reason of the scab. Acidity in the soil is detrimental, it appears, to the lower forms of plant life rather than to green plants. Many people have jumped to the conclusion that their land has become infested with sheep sorrel because of its acidity. The fact is that while this is usually the case it by no means follows that the sheep sorrel gets its acid from the soil. The sheep sorrel is one of the plants that can abide the presence of free oxalic acid, while this acid is formed in other plants, the plant at once makes a combination of it with lime or potash and locates it in crystals insoluble in the sap at ordinary temperatures, and thus renders it harmless. The oxalic acid in the sheep sorrel, like other vegetable acids, is the result of the assimilation of carbon from the air, and it does not come from the soil. But sheep sorrel will grow in a soil too acid to allow the suc- cess of clover, and hence it is the common complaint that we cannot get clover on account of the sheep sorrel. An application of lime will bring about con- ditions favorable to the clover and enable it to smother out the sheep sorrel. Not that the liming kills the sheep sorrel, but that it enables the clover to grow and overcome it. Anyone can readily test the condition of his soil by getting a piece of blue litmus paper from a drug store, and burying it over night in the damp soil. If, on taking it up, it is found to have turned to a pink color it is evidence that the soil is in an acid condition, and as our most valuable crops thrive best in a soil of a feebly alkaline nature, an application of lime to such soils will usually be beneficial. While most legumes, and especially red clover, are greatly benefited by an application of freshly water slaked lime, there is one important legume which is not thus helped. The cow pea, the greatest legume for the Southern farmer, is positively damaged by a dressing of lime. Hence one reason why the cow pea will thrive on a soil too acid to permit the growth of clover. It seems probable, too, that the microbes that exist on the roots of the pea, and enable it to get the free nitro- gen from the air, are better able to exist in an acid soil than those of the clo- ver ; for it is well known now that each legume has its own particular microbe, and that some of them may be inimical to those of other legumes, and it is rare to find one species of legume doing its best immediately after the removal of another of the same order from the land. This is only another reason for LIME AND Liming LAnpD—81 a still further development of rotations of crops. Lime will never make poor land rich if regarded simply as a manure, but, used aright, there is no means - available to the farmer that will more efficiently aid in the building up of the productivity of his land. SULPHATE OF LIME, OR PLASTER. The sulphate of lime is a natural deposit found in certain sections, and mined under the name of gypsum or plaster. Pure gypsum contains 32.4 per cent. of lime, 46.5 per cent. of sulphuric acid, and 21 per cent. of water. It is frequently burned to form what is called plaster of Paris, which, when mixed in water, rapidly hardens and is used for various purposes in the arts. The pulverized rock, known as plaster, has been largely used as a soil applica- tion. Like lime, the plaster has the power to release insoluble potash in the soil, and it sometimes has a marked effect on soils containing a large percent- age of potash. As in the case of lime, farmers seeing the effect that an appli- eation of plaster has on their soil, have at times jumped to the conclusion that plaster was all they needed to make their soil rich. But, as in the case of lime, they have soon found that the continued application soon fails to produce the effect that it once did, and that its continued use has so impover- ished their soil that they have been compelled to resort to the commercial fertilizers to restore the mineral constituents they have removed by their short-sighted policy. While on some soils plaster has had this marked effect, there are other soils on which the application of plaster has never had any marked effect. Sandy soils near the coast, which are deficient in potash, seldom respond favorably to the application of plaster. In an experiment made by the writer a number of years ago, two fields adjoining in clover of the second spring from sowing, were dressed with lime and plaster of the same money value. Both made a handsome growth, but the effect of the freshly slaked lime was decidedly more marked than that of the plaster, and the subsequent cropping of the land showed that the limed field had collected far more nitrogen than the one treated with plaster. A great deal has been said and written in regard to the use of plaster in arresting the escape of ammonia from manure, and some seem to suppose that dry plaster scattered about a stable will absorb ammonia and prevent its loss. The fact is that plaster has little or no effect in preventing loss of am- monia unless it is thoroughly mixed in the manure and moistened, for no chemical recombination can take place in the absence of moisture. Plaster, being the sulphate of lime, may, when well mixed with manure and moist- 82—Crop Growina AND Crop FEEDING ened, change the volatile carbonate of ammonia to the less volatile sulphate and thus retain it in the manure. A more efficient agent for this purpose, that can be mixed with the manure, but should not be used under the animals, is kainit, or the low grade crude sulphate of potash. The large amount of salt it contains helps to keep the manure moist, and it has the same effect of replacing the carbonate of ammonia with the sulphate and at the same time adding potash, which is usually deficient in the manure in proportion to its ni- trogenous content. Years ago in the southeastern part of Virginia, where there are extensive deposits of plaster rock and also extensive salt deposits, the salt manufacturers got up what was known as the Holston mixture, made of plaster, ashes and salt, and this mixture for a long time had a great reputa- tion in Virginia. Its beneficial effects on crops were largely due to the ashes, and, on some soils, to the plaster, while the salt, though not a fertilizer at all, may have had some effect in the solution of matters of value in the soil. Asa rule, where a farm is cultivated in a good rotation and lime is used in connec- tion with the growing of clover there will be little or no use for the plaster, unless it may be in a section where plaster is a remarkably cheap article, and even then it could hardly take the place of lime. GAS HOUSE LIME. Near the city gas houses this lime is commonly offered so cheaply that farmers are tempted to use it on their land. We have seen some disastrous results from the use of this lime as it is freshly brought from the gas works. It contains, while fresh, sulphides that are positively poisonous to plant life, and while it may be used with some good effect after a long exposure to the air, even the small percentage of nitrogen it contains in the form of sulphate of ammonia may be positively harmful, so that while it contains a good per- centage of lime, we cannot advise its use. Far better pay a reasonable price for fresh quick lime than have the gas house lime for the hauling. SULPHATE OF LIME AS A WASTE PRODUCT. Sometimes the manufacturers of fertilizers, in order to make a more con- centrated article of superphosphate, remove a portion of the sulphate of lime, which contains a small percentage of phosphoric acid. This has been sold at about the price of common plaster, and when in a good mechanical condi- tion it is a good substitute for plaster. One manufacturer offers this under the name of “stable dust,” and recommends it for sprinkling manure to pre- vent the formation of the volatile carbonate of ammonia and a consequent loss of nitrogen. Of its proper use in this we have already written. LIME AND Limine LAnND—83 AGRICULTURAL SALT The packing houses have large quantities of refuse salt which they are glad to get rid of at a low price, and there is a persistent effort to persuade the farmers that it is valuable as a manure. The editors of agricultural papers are continually applied to by their readers for information in regard to the value of salt as a manure, and there are some writers who are continu- ally claiming that soda, of which salt is largely composed, can be profitably used as a substitute for potash. Though experiments have continually shown that this is not the case, and that soda cannot take the place of potash, the subject seems to be a perennial one for some. Salt, or chloride of sodium, furnishes in itself no element of plant food essential to vegetation, and what- ever good effect may result from its use is due to its action in aiding the de- composition of organic matter in the soil, “increasing the absorbing power of soils, and, by its reaction with lime, acting as a solvent for phosphate.” Prof. Voorhees, in his work on fertilizers, well says, “There would seem to be no good reason for paying from $4 to $6 per ton for this substance, when practi- -cally the same effect can be obtained from the salt contained in the crude potash salt, kainit, one-third of the weight of which is common salt. This, too, may be had free of charge, or for the handling, as the market price of the kainit is based upon its content of potash.” SHELL MARLS. The shell marls of the Atlantic coast are almost entirely carbonate of lime, and can be used for about the same purpose as the air slaked lime. Properly used in connection with the culture of legumes, these marls have a value, but it must not be assumed that, like the green sand marl, they will furnish other forms of plant food, and, when applied heavily to soils deficient in humus, their effect may be disastrous to the fertility of the land — a long time. TAN BARK ASHES. These are another waste product about which inquiries are continually being made. Farmers, knowing the value of hard-wood ashes, are apt to con- clude that the ashes from the spent oak bark will have considerable value. While good hard-wood ashes may contain from 5 to 7 per cent. of potash, the tan bark ashes seldom have over 2 per cent. of potash, associated with a small percentage of phosphoric acid and about 30 per cent. of lime. They are not 84—Crop GROWING AND Crop FEEDING valuable enough to pay for hauling any great distance if they have to be paid for. Where they can be had for the hauling a short distance it may pay the local farmers to use them. SWAMP MUCK, OR PEAT. Many years ago an enthusiastic chemist wrote a book entitled the “Muck Manual,” and talked learnedly about gein and other things, and showed that muck mixed with spent ashes was identical in composition with cow dung. But the muck swamps of the country have not yet been transformed into cow dung, and there is far less talk about the virtures of muck than there was in the writer’s boyhood. The introduction of commercial fertilizers has so re- duced the labor of furnishing plant food to the soil that few are willing now to undertake the great labor of digging and handling peat. There is no doubt that a good quality of swamp muck, when well dried, is a good ab- sorbent of liquids in stables and barnyards, and that it will put a good deal of humus in the soil; and that finally there may be some release of nitrogen from its organic matter. But raw muck spread on the land can have very ° little effect in increasing its productiveness, and may do positive harm. If the muck is to be applied directly to the land the best way would probably be to pile it in the fall in flat heaps, and cover every six-inch layer with freshly slaked lime. After lying in this way during the Winter, it will make a much better application for the soil. But, as Prof. Voorhees well says, if the swamp can be drained, it is far better to leave the muck there and drain the land for cultivation. CHAPTER X. MIXING FERTILIZERS ON THE FARM. A great deal has been said and written of late years in regard to the mixing of fertilizers on the farm. The manurial requirements of the dif- ferent crops vary to such an extent that the same fertilizer is not always best for all, and it is of great advantage to vary the proportions of the various constituents to suit the crop grown. It is difficult and expensive to do this by buying the ready mixed articles. Then, too, it has been shown that for the soil of many sections of the country, particularly in New England, the ready made fertilizers all have too large a proportion of phosphates to the potash and nitrogen used. In the reports of analyses of commercial fertilizers by the Agricultural Experiment Stations it is a common practice to give the commercial value of each. This value means that the plant-food in the mixture can be bought at retail on the market for the price named. But the commercial value of a fertilizer and its agricultural value are two entirely different things. It must not be assumed that because a fertilizer is rated high in commercial value it is also the best for all soils and crops. The agricultural value depends on the needs of the land on which it is to be used, and in buying by the commercial valuation the farmer may be buying matter which his soil does not need, and hence will be wasting money in the purchase. If there is no need for the purchase of nitrogen, for instance, the farmer can save at least half the cost of the fertilizer by buying an incomplete fer- tilizer, containing potash and phosphoric acid only. The various Experiment Stations have given a great deal of attention to the investigation of fertilizers, and their unanimous conclusion is that the farmers can buy the materials and mix their own fertilizers more cheaply than they can buy the factory mixed, and at the same time get just as good results from their use on crops. In regard to the valuation and selling price of commercial fertilizers, the Vermont Station (Bulletin No. 71) says, from an analysis of 137 brands made by eighteen different companies, “two-fifths of the brands carried no (85) 86—Crop GROWING AND Crop FEEDING water-soluble nitrogen. Laboratory methods seem to indicate that somewhat inferior forms of nitrogen were used in certain cases, notably in some low grade goods, and by some companies. The phosphoric acid was, in some cases, quite largely in the insoluble or reverted forms, indicating apparently either imperfect manufacture, old goods, or more.or less use of (agricultur- ally) inferior forms of this article. Sulphate of potash is claimed to be present in nine-tenths of the brands, but was actually found in less than’ one-eighth of the entire number. The average selling price approximated $28.75, and the average valua- tion $17.39. Two dollars in every five paid for fertilizers met costs of man- ufacture and sale. The same amount of plant-food which cost a dollar might have been bought at retail for cash at the seaboard for 56 cents in average low priced goods, for 61 cts. in average medium grade brands, and for 66 cts. in average high priced goods. In one-third of the entire number of brands a dollar was charged for amounts of plant-food which might have been bought, in the manner above stated, for 55 cents or less. Cheap fertilizers are usually the most expensive to buy. Buying mixed goods on time is a far more costly method of getting plant-food than is home mixing or buying on special order.” Low grade fertilizers, or complete fertilizers sold at low price, are always the most costly to the farmer. Several years ago a dealer in one of our cities, who was having fertilizers made for his trade by a chemical firm, sent me a package of the burnt sand and iron oxide left in the manufacture of sulphuric acid from iron pyrites, and wished to know if it had any fertilizing value, as he found that the manufacturer was using 500 pounds of it in a ton of low grade goods made for his sales. 1, of course, told him that it was perfectly valueless. The farmer who bought these goods was attracted by their appar- ent low price, when, in fact, he was paying a high price for all the article contained of value, and was then paying freight on one-fourth of the bulk in an article that was of no use to him whatever. In some States, notably in North Carolina, the law in regard to fer- tilizers is so rigid and so strictly enforced, that manufacturers are compelled to fully come up to the guarantee printed on their bags, and in these States the farmer is pretty sure to get what he buys, and the only objection is that the prices charged are entirely too high. The great argument which the manufacturers of fertilizers have used against home mixing has been that the farmer cannot mix the goods as well as they can with their machinery, and that if he could do so, they could with their machinery mix them more cheaply. The fact is that with the materials at hand, the farmer can mix in any proportion fully as well as the factories MixiING FERTILIZERS ON THE FARM—87 mix the goods, and at a cost that will not be felt at all. According to the organ of the fertilizer makers the cost of mixing and putting their goods on the market is about $6 per ton, and the same paper figures up this cost by adding up drummers’ salaries, postage, telegrams, travelling expenses and a lot of other items, none of which the farmer mixing his own goods would have to pay, but which are really paid by the manufacturers and those who buy from them ready mixed goods. So the fact is that the farmer can not only get the materials at retail for less than they are charged for them in the ready mixed articles, but he can also mix them far cheaper than the factories can. The same bulletin to which we have referred above, says in regard to the guarantees and claims of the fertilizer makers: “Guarantees are often designedly confusing and convey wrong impressions. Nitrogen, phosphoric acid and potash are what make fertilizers agriculturally and commercially valuable. They are often expressed, however, in guarantees as ammonia, bone-phosphate of lime and sulphate of potash. This is done to make a semblance of giving large percentages of plant-food. Thus ni- trogen equivalent to ammonia 2.50 per cent. promises really only 2.06 per cent. of nitrogen; available phosphoric acid equivalent to bone-phosphate of lime 21.80 per cent. promises but 10 per cent. available; and potash (sul- phate) 3.70 per cent. but 2 per cent. of potash.” Buyers should remember these facts, and ignore in the guarantee everything except the lower figures for nitrogen, (not ammonia or nitrogen equivalent to ammonia), available phosphoric acid and potash (not sulphate of potash, or potash sulphate, or potash equivalent to or equal to sulphate). The law in the State of North Carolina, which in most respects is the best in the country and the most rigidly enforced, allows no sliding scale of percentages on the bags, but re- quires that the sack shall have printed on it the actual percentage of nitrogen, phosphoric acid and potash. Only this and nothing more. If all the States would pass a similar law there would soon be an end to the long so- called analyses printed on the bags, simply for the purpose of befogging the farmer into the belief that the sack contains a great deal more than it does. We have at hand from a correspondent a sample of a commercial fer- tilizer, on which is printed the following: GUARANTEED ANALYSIS. Por rio). ae oe ae a 2 a 2.10 to 2.50 per cent.

All the rest is put there to make the farmer think there is a great deal in it, while it is, in fact, a very low grade fertilizer. The “organic matter, ete.,” is probably “filler” put in to make bulk. This is but a single sample of thousands of similar “analyses” on fertilizer sacks all over this country. The manufacturer who cannot state just what his article contains must be a poor manufacturer, or puts the sliding scale there to crawl out on. If you see a sliding scale of percentage you may be sure that the lowest figure comes nearest to what is the actual per cent. But there is a great deal less of actual swindling in fertilizers since the laws for the inspection have been adopted in nearly all the States, and the farmer dealing with firms of reputation can usually depend on getting what he orders. The great objection to the ready mixed goods is not their quality, but the fact that they are sold at too high a price, as is evident from the fact that buyers at retail can get the same plant-foods for less money. Bulletin No. 139 of the New Jersey Station, says in regard to home mixing of fertilizers: “Home mixing has been carried on with entire satisfaction by a number of farmers for several years. ‘The Station has encouraged these efforts as of value to the individuals themselves and an object lesson to their neighbors, since it renders them familiar with the kinds and forms of plant-food, teaches them to think of pounds of nitrogen, phosphoric acid and potash, rather than tons . of a particular phosphate, and in general unfolds the mystery which envel- opes the make-up of fertilizers in the minds of many.” Bulletin No. 53 of the Maine Station well says: “That which transcends everything else in the purchase of fertilizers is to know what you want and then get it—get it as cheap as you can and still get the plant food needed. No one would think of buying salt for sugar because it can be obtained at a lower price, but the writer has knowledge of the purchase of nitrogen when potash was needed, simply because the trade value of a nitrogenous fertilizer as printed exceeded its selling price.” In Bulletin No. 132 of the New Jersey Station, a number of analyses are given of fertilizers mixed by farmers for their own use, and the results show that the proportions of the different constituents was as well main- tainded as in the manufactured goods. “As a method of economical pur- chase of fertilizers, either mixing them at home, or having them especially compounded at the factory, seems to be equally recommended by the experi- ence here reported. This opportunity of saving in the purchase of fertilizers is open to all who will study their crops and soils, learn what they need, and secure it by the more business-like method. It is a combination of com- MIXING FERTILIZERS ON THE FaRM—89 prehension, co-operation and cash that effects these reductions in the cost of fertilizer supplies.” This is the secret of the whole matter. The prices of ready mixed fertilizers have to be kept high because of the long credits and bad debts, and the men who buy them have to pay these bad debts of others in advanced prices. Buying the materials for cash in wholesaledlots through a combination of neighbors will always result in a great saving. It is far better to borrow the money to pay cash for fertilizers than to pay the credit price. Bulletin No. 65 of the Vermont Agricultural Experiment Station, says: “Home mixtures made in this State furnished from 30 to 50 per cent. more plant-food at the same cost than did average manufacturers’ mixtures.” Dr. C. W. Dabney,: Director of the Tennessee Experiment Station, writes: “Farmers who take their life work seriously and study earnestly the experimental work of the State Stations, for the purpose of informing them- selves with regard to the useful ingredients of fertilizers, the proper mode of applying them and such matters, are getting more and more into the habit of buying the raw materials for fertilizers and mixing them themselves, or else they have a compound mixed at a factory according to their own formula and from materials of their own selection.” Farmers’ Bulletin No. 84, U. 8. Department of Agriculture, treats of the various objections raised to the practice of home mixing. “Farmers are persuaded that the compounding of fertilizers is an intricate and difficult matter, requiring extensive acquaintance with chemistry, costly machinery and great technical skill. The case well illustrates the old adage, that a half truth is a whole falsehood. The production and manufacture of fer- tilizing materials—that is, the selection, quarrying, grinding and acidulation of phosphatic rock; the drying and grinding of slaughter house refuse, the production and refining of such materials as nitrate of soda, sulphate of ammonia and muriate of potash—all these are distinctly manufacturing processes, which require chemical or technical knowledge, skill in manipula- tion, and expensive machinery. But these operations are entirely separate and distinct from the compounding of mixed fertilizers. Each of the materials named comes from the manufacturer in condition to be used by itself as a fertilizer, and each one is so used for special purposes. The com- pounding of these materials under a proprietary brand into a mixed fertilizer, is no more a manufacture than is the mixing of a ration of corn meal and bran to be fed to a cow. The only difference is that the ration which is designed to be distributed uniformly to thousands or millions of plants requires to be more carefully mixed than that fed to a single cow. If we were feeding each plant by itself no mixing would be necessary, or if we 90—Crop GROWING AND Crop FEEDING were giving the different elements of a ration at different times; as for instance, when we apply superphosphate and muriate of potash to wheat in the fall and follow with nitrate of soda in the spring. This point, of the essential. difference between those operations which are legitimately called manufacturing and those which are simply mixing, should be clearly under- stood. When the farmer learns that he can mix his own fertilizers and thereby materially reduce their cost, the use of fertilizing materials will be largely increased, and the final outcome will be a benefit and not an injury to the legitimate: trade in fertilizers.” This is just what the writer has been insisting upon through the agri- cultural press for years, but such is the short sighted policy of the manu- facturers of fertilizing materials, who are generally at the same time mixers of the materials in any number of fancy brands, many of them identical except in name, that they put all sorts of obstacles in the way of the farmer’s getting the raw materials for mixing his fertilizers at home, and constantly endeavor to make the farmer think that their process of putting these ma- terials together is a matter of great skill and experience, and cannot be done without the use of expensive machinery. Machinery is used, of course, in the mixing on a large scale, as a matter of economy, and to increase the profit to the mixer. Bulletin No. 173 of the New York (Geneva) Station showed that the average selling price of mixed fertilizers in that State per ton averaged $6.25 more than the separate ingredients could be bought for at retail. Inas- much as this was far higher than the actual cost to the large mixer, it can easily be seen that the profits of mixing on a large scale must be large, and that the wise farmer can easily save, even in buying in retail quantities, a considerable sum. Bulletin No. 45 of the Maine Station says; “One of the claims which fertilizer manufacturers are making for the superiority of their goods over home mixed fertilizers is that the former are manufactured. This should mean, if it means anything, that the goods are more evenly mixed, and therefore, more uniform. In the tables given on the previous pages it will be found that in some instances in which two samples of the same brand have been taken and analyzed, that they differ from each other quite materially. The samples were taken with a great deal of care by experienced men from a large number of packages. It would not seem difficult to make home mixed fertilizers which should run as uniformly as some of the brands here re- ported upon. Bulletin No. 79 of the Kentucky Station says in regard to the selection of the proper fertilizers, “Their profitable use will depend upon a knowledge MIXING FERTILIZERS ON THE FaRM—91 of the needs of the particular soil to which they are to be applied, and the requirements of the crop to be grown. The latter knowledge has been gained once for all for most farm crops by a scientific study of these crops, but the needs of the soil must in most cases be learned by the farmer himself, either from systematic field experiments, or by observation and experience. If it is necessary for a farmer to use commercial fertilizers, and he is working upon a kind of soil that has not already been tested, we believe it will pay him to learn its needs by carrying out systematic experiments with fertilizers. The experiments made at this Station amply illustrate this. It would be very unprofitable to buy phosphates for use on soil like that of the Station farm, but potash salts could be profitably used there on most crops. This is because the soil is already rich in phosphates. But if it were deficient in phosphates, as is the case with many soils in this State, it would be unprofitable to use potash salts alone, and one would have to supply phosphates. It is, therefore, necessary in purchasing a commercial fertilizer to consider, first, what our soil needs for the crop to be raised, and then to look for the fertilizer contain- ing most of these substances, in an available form, as shown by its chemical analysis and guaranteed by the manufacturer, at the least cost. It is well to bear in mind, also, that nitrogen compounds are the most expensive con- stituents of commercial fertilizers, and if we can keep up our nitrogen supply by means of clover, cow peas, or other leguminous plants, or by barnyard manure, and purchase only such phosphates and potash as may be needed, we will have accomplished a great saving.” Here, too, is a strong argument for home mixing, since it will rarely happen that we can get a ready mixed fer- tilizer exactly suited to our soil and crops without buying at the same time something we do not need. Bulletin No. 80 of the Vermont Station shows that in the past spring (1900) the average price of mixed fertilizers was $28.73, and the average value, based on the retail price of the ingredients, was $18.08, another evidence of the saving to be made in home mixing. But the most complete investigation of the value of home mixing of fer- tilizers has been made at the Ohio Agricultural Experiment Station. It is claimed by the factory mixers of fertilizers that in using tankage as a source of nitrogen they have a great advantage in the fact that they treat their tankage with sulphuric acid to render it more soluble, and hence far better than the untreated tankage used in the simple mixtures. It was shown by the experiment at the Ohio Station that this causes great loss of nitrogen from fall application to the wheat crop and “it follows, therefore, that if the treatment of tankage with sulphuric acid serves to make its nitrogen as solu- ble as that in sulphate of ammonia—and this is precisely what is claimed for it—then such treatment is injurious and not beneficial to him who would 92—CroPp GROWING AND Crop FEEDING use tankage in the fall as a carrier of nitrogen‘to wheat.* * * * Our experi- ments do not support the claim that the acidulation of tankage is necessary, unless the tankage has been adulterated with leather scraps or similar material; they rather show that it is a disadvantage. * * * The sulphuric acid used in acidulation costs only about one-third as much per pound as the fertilizer is sold for. In point of fact, the manufacturer can very well afford to pay $6 to $8 per ton for sulphuric acid to be sold again at $20 to $30. * * In the field experiments of this Station factory mixed fertilizers, made by firms of high standing, produce no greater crops than home mixed fertilizers of equivalent composition. The cost of the factory mixed fertilizers was greater by 50 to 90 per cent. than that of the equivalent home mixtures. Physical and chemical examination of the two forms of mixtures show that the factory mixed fertilizer is not more homogenous in its character than that mixed by the farmer. Fertilizer materials may be as perfectly mixed with a shovel on a barn floor or in a large box as by the most elaborate mixing machinery.” HOW TO MIX FERTILIZER. There is a widely prevalent idea that the chemical constituents of a fer- tilizer must have a “filler” mixed with them to make bulk. This notion has arisen from the fact that fertilizer mixers commonly use worthless materials for fillers in low grade goods, so as to be able to sell them at an apparently low price, while still getting full prices for all that is of value in them. The various fertilizing constituents are already combined in such a way that no further filler is needed, and they only need to be mixed in the desired propor- tions. This mixing we have shown can be as well done on a barn floor as by the most elaborate machinery. Having determined from a formula the proportions in which the articles are to be mixed, is is a simple matter to spread them out in layers on the barn floor, and then having set up an ordinary sand screen to shovel the mass through the screen repeatedly, beating up all the lumps, till a perfect mixture is made. After the mass has been shovelled through the screen two or three times it will be sufficiently mixed for all practical purposes. In fact, if we could distribute the materials over the land in the exact proportions needed, there would be no necessity for mixing them at all, but this would take a great deal more labor than mixing and spreading at one going over the ground. We give elsewhere a series of formulas adapted to various crops on dif- erent soils. These are largely for complete fertilizer mixtures containing due MIxING FERTILIZERS ON THE FARM—93 proportions of nitrogen, phosphoric acid and potash. But it must not be supposed that these are in every case necessary or profitable. They have been devised from the study of the manurial requirements of the various crops, as- suming that the soil needs them all. But we will try to show how, by good farming and a proper rotation of crops, we can avoid the constant application of commercial fertilizers to every crop grown. The Experiment Stations have devoted so much time and labor to the study of the manurial require- ments of crops that farmers are apt to imagine that all they have to do is to suit a fertilizer to the crop in order to make it. CHAPTER XI. THE MAINTENANCE OF FERTILITY. The maintaining and increasing of the productive capacity of the soil in a profitable manner should be the ultimate aim in the use of manures and fertilizers of any kind, and not the mere speculating on how much sale crop we can get through the use of a certain fertilizer mixture. This has been the course over large sections of the country, especially among the cotton farmers of the South, until with the majority of the farmers the first question asked is, “How much and what kind of fertilizer shall I use to get a certain crop?” Men frequently write to me that they have a certain field which last year made, say, ten bushels of corn per acre, and they want to know what and how much fertilizer they shall apply to that same field to make it produce 50 bushels of corn per acre. We have to reply, of course, that it cannot be done in that way. The physical and mechanical condition of the soil has as much to do with its productivity as the amount of plant-food it may contain. When a field, through a long course of bad treatment, has been deprived of its humus, and has gotten into a bad mechanical condition, no amount of fertil- izer will at once restore it to its normal state of productiveness. It took years to complete the robbery of the soil and years of proper farming will be required to restore it. USING FERTILIZERS IN CONTINUOUS CROPPING. There are many men in the South who imagine that they are farming profitably by growing cotton year after year on the same ground with an an- nual application of fertilizers, simply because they show some profit over the cost, and not reflecting that they could secure greater profits by proper rota- tion and a smaller expenditure of fertilizers. As compared with real farm- ing, their cultivation can easily be shown to be unprofitable. Especially is this true when the crops are the cereal grains. At the Ohio Station a long (94) THE MAINTENANCE OF FERTILITY—95 series of experiments have been made with various rotations and also with cereal crops grown on the same soil year after year with the use of commer- cial fertilizers. They thus summarize the results of the continuous crop- ping. “At the prices at which mixed fertilizers are sold in Ohio the attempt to furnish all the nitrogen, as well as all the phosphoric acid and potash, re- quired to produce increase in cereal crops grown in continuous culture, has invariably resulted in pecuniary loss, although very large increase of crop has been thus produced.” ‘The rotation of cereals with nitrogen gathering crops, therefore, has been shown to be absolutely essential to the profitable use of commercial fertilizers in any form.” This confirms all that we have found through a long experience in the cultivation of the soil. The constant use of complete fertilizer mixtures for the production of sale crops only, has brought poverty to the soil over large sections of the country, and of course poverty to the cultivator. It is for the purpose of aiding in the bringing about of a change in this respect, and of showing how fertilizers may be used profitably for the improvement of the condition of the farm and the farmer alike, that we have undertaken the work of writing this book. The writer is a Southern man, born and raised in the South, and it has been his life’s work to do all that he can to aid the farmers of the South especially, to the adoption of better methods, for he is convinced that the wasteful use of fertilizers and the continuous cropping of the land in sale crops is responsible for the sad condition of farms and farmers in the South. And it is not only in the South, but in, other parts of the country, where the farmers are just beginning to realize that their soil is becoming run down, and needs help, that there is danger that they, too, will imagine that in the bag of fertilizer they can find all that they need, and they are beginning to start in the same road towards “old fields” that the - South has travelled. The old, down hill road has been an easy one to follow, and required little thought; the new one calls for careful study and experi- mentation on the part of the farmer. He can no longer succeed by the old, happy-go-lucky methods, but must become a student and a book farmer to a great extent. By maintaining the fertility of his land he can alone hope to succeed. This cannot be done by an annual gambling in fertilizers and the growing of a single crop year after year on the same land. No matter what the crops are, whether wheat on the plains of the Northwest, corn on the prairies of the Middle West, tobacco in Virginia or Ohio, or cotton in the South, single cropping everywhere tends to soil exhaustion and the depleticn of the farmer’s resources. One characteristic of the Northern farmers in contrast to their brothers in the South, is the readiness with which they see errors in their work and 96—CRoP GROWING AND CROP FEEDING make a change for the better, while the innate conservatism of the Southern farmer holds him longer in the old ruts than his Northern competitor. The great decrease in the wheat crop on the plains of Dakota showed plainly that the wheat growers there were, as we have said, straight on the road to “old fields” as those of the South have long been. But of late, the farmers of Dakota are realizing their error, and are going into cattle. They can do this all the more profitably now that the sheep have driven the cattle from the great ranges of Colorado, Utah and other sections where cattle formerly were raised in immense numbers. These great ranges of public land no longer carry their herds of cattle, for sheep have gotten possession ; the cattle of the future will not be raised on the free ranges, but on the lands belonging to the farmer, and the cattle feeding of the Eastern States will once more become profitable. The Dakota wheat growers are wise enough to see the error of their one-cropping, and to take advantage of the changed conditions in the cattle industry. Having taken this step before the “old fields” were present in all their hideous barrenness, the Dakota farmer will have the great advantage of his Southern brother in the unexhausted condition of his soil and its capacity for the production of grass. But if the farmers in a section where cattle must be housed and fed for nine months and where great storage _ must be made of winter feed, can produce beef cattle at a profit, what should the farmers of sections which can produce the finest of forage plants in the greatest abundance and where the cattle can roam in the fields nearly every day in the year, do? We cannot too often insist that there can be no real prosperity on the farm, no real home making and nowhere near the profit in farming, with one crop, and selling that in the raw state. The growing of forage crops and the keeping of live stock lies at the very foundation of all rational methods of soil improvement and the maintenance of the fertility of our acres. The farmer who transforms some of his raw products into a more finished product always realizes a larger price for his product than the man who constantly sells only the raw product. Some years ago the writer made a visit to Nebraska for the purpose of studying the growth and manu- facture of beet sugar as practiced there. We were struck with the beauty of the wide spread of corn fields, and took occasion to talk with the farmers not only about their beet growing, but in regard to other crops. Asking one Ger- man farmer what corn was worth per bushel, he replied that he believed it was about 20 to 25 cents, but that he did not sell corn as some of his neighbors did. His corn went into hogs and they carried themselves to the depot, and he got 50 cents a bushel for his corn and had the manure left, though he seemed to care little for that, for like most farmers on the new prairies, he thought the soil inexhaustible, like those further east who are now buying THE MAINTENANCE OF FERTILITY—97 fertilizers. I said to this man that his course was wise, but that he might go still further, for I had noticed that in the thriving young city near him ihe grocery stores sold only the packed hams and bacon from Chicago, and that his pigs had paid the freight both ways and a profit to the packer, and that he could do some home packing and sell the bacon as well as they and probably get a better price than the packer’s meat brought. The German seemed to catch the idea and remarked that he believed he would get 75 cents for his corn. As I write, the hams of the packing houses can be bought at retail here for 10 to 15 cents per pound, while at the same stores the famous hams of the Southeast Virginia farmers are selling for 22 cents per pound. By the production of a superior quality of cured product, the farmer can realize large prices for his grain and not have to take what the market offers for the raw product. Lay it down as a law that no country or community ever became permanently rich by the sale of its raw products only. To some extent the South is beginning to learn this, and all over the country cotton mills are being built and run at a profit and the labor drawn to them from the farms has to be fed by the farms, and a new inducement is offered to the Southern farmer to produce food crops, as his market is growing more rapidly than its supply. WHY A SHORT ROTATION IS BEST. The Ohio Station, in the series of experiments undertaken for the pur- pose of demonstrating the best method for maintaining the fertility of the soil, arrived at the following conclusion: “Thus far in these experiments, the surplus nitrogen accumulated by a crop of clover, the roots only being left in the ground, has not been more than sufficient to satisfy the demands of the one crop immediately following the clover.* * * * It appears to be clear, therefore, that under the conditions of this experiment, which is made on soils of reduced fertility, and on which there has been no systematic culture of leguminous crops previous to the beginning of this test, we are not main- taining in the soil a supply of nitrogen sufficient for maximum crop produc- tion by simply growing one crop of clover in five years, the roots of which only are left in the ground, the tops being made into hay and removed from the land.” Hence it is evident that where it is desirable to have a rotation extending over five years there must be another leguminous crop introduced in order that the supply of nitrogen may be maintained for the production of maximum crops. This can easily be accomplished in a three or four year rotation, and farmers in sections where it has long been the practice to run the land in grass as long as the mowing could be kept good, before going back 98—Crorp GROWING AND Crop FEEDING to corn and small grain, are beginning to realize that they have been losing greatly by the practice, and that permanent pastures and a short rotation in the cultivated land are the things to be sought for. The reason for the desira- bility of the short rotation and the more frequent bringing in of the legumes is obvious if we reflect on the nature of the nitrogen. Most of the nitrogen collected by the legumes is in the form of organic matter in the roots left in the ground. We have shown that green plants do not use nitrogen till in the form of a nitrate. Hence this organic matter must go through the process of decay, and of change in the soil into a nitrate. This is, as we have seen, accomplished through the agency of the nitrifying microbes in the soil. When these have done their work, the nitrogen contained in the clover or pea roots is transformed into a nitrate, and if not then at once used by the plants it is rapidly washed out of the soil. Therefore, if there is a long interval between the crops of lezumes, we cannot keep up the supply of nitrogen in this way, and will have to resort to the purchase of complete fertilizers, which a short rotation would render needless. But as organic matter accumulates in the soil, forming humus, it is probable that the complete nitrification may be slower by reason of the increasing acidity which is less favorable to the activity of the nitrifying organisms. Then it is that the use of lime becomes an important adjunct and restores the favorable conditions for nitrification. With a three year rotation, a light dressing of lime once in each alternate round of the rotation (or once in six years), will be found a great aid in the development of the productivity of the soil. Or even a still lighter applica- tion every round of the rotation may prove best. A SHORT ROTATION BEST FOR SPECIALIZED FARMING. While we are convinced that the greatest evil in farming has been con- tinual cropping with a single crop, and that the only way towards the im- provement of the soil is through a diversified farming, this does not mean that a farmer should grow a little of everything his climate will produce. He should study his conditions carefully, and find out what is the best money crop for his section and his land, and then should contrive a rotation intended to best promote the success of his money crop. The wise farmer will always have a specialty, to the increased production of which he will bend all his energies, while endeavoring in every possible way to reduce the cost of its production by making his subsidiary crops aid in the defraying of the expenses. His specialty may be cotton, tobacco, wheat, corn or any other particular crop, and his aim should be to grow the money crop more cheaply and at the same time to greater perfection than anyone Ths THe MAINTENANCE OF FERTILITY—99 around him, if possible. It is not always the sign of the best farming for a man to grow a specially large crop of something on a small area of land. The phenomenal yields of corn, for instance, which have been produced in compe- titions for premiums, are interesting mainly as showing what can be done with heavy feeding and good culture, but they are usually financial failures. What we should aim at is to get the widest possible margin between the cost of the crop and its sale value. This calls for skillful management of the land, and the best of cultivation, as well as a wise selection of what is to be sold from the farm. Some of our Southern friends have imagined that the way out of the old one-crop farming is a diversification by which the farmer shall grow someting of everything his climate will allow, and shall not buy anything which he can grow. ‘This sort of aimless diversification is not what we want, but a systematized agriculture suited to the conditions under which the farmers live. The cotton farmer in the warm soils of the Southern seaboard could doubtless grow some wheat, but he will soon find that he can buy all the flour he needs more cheaply and of better quality then he can grow the wheat and have it manufactured on a small scale. The farmer in Southern Maryland could doubtless grow a little cotton, as they once did under the old home manufacturing practice, but he would soon find that he had better stick to his wheat or tobacco and buy his cotton goods. The same rule holds good in all parts of the country. The money crop of each section has become such through the operation of natural laws, and none can afford to ignore these. SOME OF THE MISTAKES MADE, When a farmer moves from one section to another having an entirely different soil and climate, he needs to study his new conditions well. He will in fact, have to unlearn a great deal and to learn things that he did not for- merly need to learn. Going into a new section, one is apt to imagine that he can do a great deal better than the people already thete, and as he has been a good farmer in his old location, he is apt to think that the same methods which were best there will be the best in his new location. The people among whom you have come may not be farming as well as they do in the section where you formerly lived, but there will always be practices in every old settled section which are the outgrowth of experience in that partic- ular soil and climate, and which a newcomer cannot afford to ignore. North- erm men coming into the cotton belt, as a rule, always want to grow something else rather than cotton. They see that under the old methods, the cotton farmers and the cotton farms have grown poor, while the fertilizer manufac- L. of C. 100—Crorp GROWING AND Crop FEEDING turers have grown rich. They therefore jump to the conclusion that cotton and fertilizers are bad things, and are wrong in both conclusions. The warm coast plain of the South could have no better money crop than cotton, and the commercial fertilizers, while bringing disaster to the farm and the farmer when used in the wasteful way in which they have been used, can be made, in the hands of a good farmer, the most potent means for building up the fertility of the soil. For a man to go into the cotton belt and engage in general farming and ignore cotton would be a great mistake, for no farmer, as a rule, can afford to ignore the money crop of his section, unless he has some specialty which takes him out of the list of general farmers. — It is true that there are large sections of the Southern uplands where cotton is grown and where it should never have been grown, and there, with the growth of knowledge in regard to farm methods, the farmers will soon learn that their lands are better adapted to grain, grass and stock than to cotton; and in other parts of the country the methods are undergoing a gradual change so that each particular section is finding out what it can best do, and what it should let alone. Specialization, with a properly arranged rotation, is the road to success. The growing of a single crop year after year on the same land, no matter how much commercial fertilizer you may buy, leads finally to poverty of soil and of the farmer, too. No matter what the crop the result is pretty sure to be the same. In the great peach growing section of Maryland and Delaware, the men who have been, as a rule, most successful in the long run, have not been the men who put their entire land into peaches; but rather those who recognized the adaptability of their soil and climate to peach culture, who made the short- lived peach trees simply a part of their farming and gave them the best at- tention, knowing that in a few years the orchard must go back to crops of a different nature, and must be kept up in its fertility to correspond with the other fields when one of these was taken for the orchard. Prof. Roberts in his book, “The Farmstead,” says, “Many farms in Western N. Y. have been almost exclusivel} devoted to the raising of grapes, which, when abundant, or moderately so, sold at ruinous prices. It is noticed that where only an eighth or fourth of a farm was devoted to vines, the yield was not only pro- portionately larger, but the quality better than where nearly all the land was used as a vineyard. Where diversified agriculture was carried on to a limited extent and plantations were restricted, the low price of grapes made no serious inroads on the income. Where all the land was given to grapes, work was intermittent, the farmer being overtasked at one season of the year and idle at another. The demoralizing effect on the farmers and their families of this army of unrestrained youths and loungers of the city, which, for a brief THE MAINTENANCE OF FERTILICFY—101 period, swarms into the districts devoted to specialized crops, as grapes, ber- ries and hops, is marked.” Single cropping is destructive to home life wherever it is practiced. In the cotton growing sections, the negro tenants, who grow no other crop, are idle during the winter; as it takes about all their share of the crop to pay the merchant who carried them during the summer, they are in a measure forced to live upon the country, and the whole system is an encour- agement to vice. If the tenants were compelled to farm in a systematic man- ner it would tend towards the building up of the land and the increased pros- perity of the tenant. There is no hope for the permanent improvement of the Southern cotton lands so long as the “cropping” system prevails. CHAPTER XII. HOW TO USE COMMERCIAL FERTILIZERS FOR THE MAIN- TENANCE OF FERTILITY. The whole of the cotton growing section of the South Atlantic States furnishes an object lesson of the ruin that comes about through the inju- dicious use of commercial fertilizers, and the growing of cotton on the same land year after year. This is most plainly seen on the rolling, red clay uplands. Steep hillsides, which a wise agriculture would have left in the protecting forest cover, have been cleared and cultivated in cotton. As the humus in the soil was exhausted, the red clay tended to wash into gullies under the great down pour of summer rains that prevail. Year after year the gullies have been made larger till cultivation became impossible, and now all over the upland country of the South these ruined and irreclaimable hillsides are staring the traveler by rail in the face, and giving a bad impression of the whole country; and all the rivers run loaded with the wasted fertility of the soil. Thousands of acres of these gullied hillsides can only be redeemed by a restoration of the great forest cover, which should never have been removed in the first place. The soil and the thousands of dollars’ worth of fertilizers which have been wasted in the culture of these hills are both gone, and the land has been literally used up for a few crops of cotton. Under former conditions, when the large plantations with their army of slaves were in their prime, a notion prevailed that cotton was the one crop that would not fit into an improving rotation. Before the introduction of commercial fertilizers the practice was to cultivate a piece of upland as long as it would pay to grow the crop, and then to take up another piece, letting the first grow up in pines. With the change in labor conditions, and the introduction of commercial fertilizers, it was found that the old land could be made to produce a crop, and then the farmers imagined that all they had to do to get a crop of cotton was to use commercial fertilizers. These have been mainly purchased on credit, with the invariable result that the manufacturers, in order to protect (102) CoMMERCIAL FERTILIZERS FOR MAINTENANCE OF FERTILITY—103 themselves against loss, have been obliged to charge high prices for their goods. So long as the cotton only, was sold, and the seed was returned to the land, the depreciation was slower. But of late years the great demand for the seed in the manufacture of oil has led to many selling the seed outright, imagining that they were making an additional profit from the crop. While it is true that some farmers exchange their cotton seed for meal and oil to advantage, there are thousands who sell them regularly. This is especially true of the tenant croppers whose interest in the land is less than their inter- est in the immediate crop. The oil, being one of the products of the plant which was derived from the assimilation of carbon from the air, has no value as a manure to the farmer, and where a fair exchange can be made, it is better for the farmer to make the exchange and get the more readily available nitro- gen in meal, while the hulls will make a good absorbent of manure. It is true that they are largely used as food for stock, but they are at best only a makeshift of the poor farmer, for there is not a section in all the cotton belt where far better food may not be grown, while at the same time the crop that furnishes the food will help the land. One of the saddest sights one sees daily in this cotton country is a farmer, or rather a man who is cultivating the soil, hauling home from the city oil mill, baled cotton seed hulls to feed his mules with. And this in a country where the finest crops of the best hay in the world can be grown from the cow pea, and the land made better for cotton production by reason of the forage growth. The whole crop, seed and all, was sold, and now the farmer buys back the poorest part of the crop to feed the mules. And this is not the worst of the whole sad business, for the cotton must not only pay for the mule feed, but for the mules themselves, for the idea of keeping a breeding animal never seems to enter the minds of the men who are working in the one crop of cotton; the cotton must carry the whole burden while the soil gets poorer and poorer. I write of these things particularly because they are daily before me, but there are farmers whose interest is in other crops, who are doing as badly as the cotton farmers. We recently traveled and spoke at Farmers’ Institutes in the State of Maryland, in sections where the farmers are improving in many respects, and are paying attention to stock and the dairy, and over the wide, level fields where the corn binder could run with profit, | saw the old time method of topping the corn and stripping the blades still practiced, and the stalks and husks left in the field; thus sacrificing a large amount of food that the shredder would have turned to profit in the feeding of cattle. In the great corn growing sections of the Central West, too, we see the same waste of food and lack of interest in the complete utili- zation of the greatest forage crop of America, the Indian corn crop. There 104—Crorp GrRowInG AND Crop FEEDING is not a section of all the corn growing belt where there is not much of this waste, and where thousands of cattle could not be fed instead of the hundreds that are fed. And even in the greatest corn growing sections of Ohio, Indi- ana and Illinois, there are farmers who write to us asking for fertilizer formulas for the restoration of the productiveness of their lands; while they are annually wasting food that would turn them a profit in feeding, and give manure for the acres that are hungry for it. Properly managed, there is no part of the corn plant that cannot be profitably utilized as food for stock, and the greatest leak today in American agriculture is in the waste of corn stover all over the land. No farmer, no matter how fresh and fertile his | soil, can afford to plow corn stalks into his land, when, by proper treatment that will largely increase the stock supporting capacity of his farm. While commercial fertilizers are useful and even indispensable in these high pressure days, no farmer can afford to neglect the manurial resources of the farm itself, or waste what would give him profit if rightly handled and fed. THE ROTATION FOR THE COTTON FARM. In all the true cotton country, the sandy and level lands along the coast and extending one or two hundred miles or more inland, and the widespread prairie lands of Texas, cotton can be grown in an improving rotation as the special money crop to the greatest advantage. In all the South Atlantic coast country the use of commercial fertilizers in some way has become a ne- cessity. The Texas cotton growers as yet may not feel the need of them, but it is only a question of a few years when they will need them, unless a wiser method of farming with cotton is adopted. The Experiment Stations in the cotton country have spent a great deal of time and labor on the study of the manurial requirements of the cotton crop, and far too little time on the dem- onstration of the most economical methods of meeting these requirements. Formulas without number have been devised for cotton and other crops, until the farmer has been led to suppose that all he needs to grow the crop is a formula for a fertilizer. While the investigations of the Stations have demonstrated the needs of certain plants in the way of food, with great pre- cision, there is now a great need for the demonstration of economical methods for the bringing about of these conditions in the soil. While it has been demonstrated that the cotton plant needs nitrogen, phosphoric acid and potash in certain proportions, it by no means follows that these should be purchased annually for the purpose, if by proper farming we can accumulate any of them in the soil for the crop. The great need in all the cotton country, the need that no purchase of fertilizers will ever fully meet, and without COMMERCIAL FERTILIZERS FOR MAINTENANCE OF FERTILITY—105 which the development of the productive character of the Southern uplands must be slow; is the keeping of cattle and sheep, and the growing of forage crops for their feeding in a profitable manner. “But,” said a cotton farmer to the writer, when he was urging the feeding of cattle as the very foundation of profitable farming, North or South, “I do not want to be pestered with eattle, for I can buy a lot of fertilizer every spring and make a profit out of it in the growing of cotton.” This man, fortunately, has a large body of very fine Jand, well supplied with humus, and on which commercial fertilizers act very finely; doubtless what he said was true and that he does make a profit in cotton farming with heavy doses of fertilizer on his land. But it would be easy to demonstrate that the profit would be much larger and the outlay for fertilizers much less by farming instead of merely planting his land. But there are thousands of farms in the South which have been so com- pletely run down by bad culture that even the application of fertilizers by a Station formula gives no profit. It is a common practice among the larger cotton farmers to figure everything by the mule. ‘The area of land does not enter into the calculation, but only what they can clear from each man and mule in the cotton field. At ten cents per pound, a man and a mule can make, on land yielding half a bale per acre, about $600 worth of cotton. This $600 must pay for the fer- tilizer used on the land, and must feed the mule and the négro for a year, while the same land probably could be, in a little while, brought to the pro- duction of a bale per acre with less direct expenditure of fertilizers, is farmed instead of being merely planted. In all of our Southern cities the refrig- erator cars from Chicago are daily bringing beef for our consumption, in a _country where more and better forage can be grown than in the West; and where men are planting thousands of acres in cotton with hardly a hoof on the land except the mules which work the fields in summer and loaf all winter. A proper rotation for a cotton farm involves the feeding of stock. The feeding of stock requires forage and grain. The growing and harvesting of forage and grain and the feeding of stock in winter, requires regular labor from year’s end to year’s end, and gives steady employment and a better class of laborers by reason of the steady work. It means cash coming in at different seasons, which enables the farmer to buy for cash, and thus lightens greatly the expense falling on the cotton crop. It makes the farmer a reader and a student, and in this way has its influence on the home, for when people get interested in books they soon improve in the home making. During the late depression in the price of cotton the writer was con- tinually being appealed to by cotton farmers for information in regard to the 106—Crorp GROWING AND Crop FEEDING culture of one crop or another, which the writers wanted to put in in the place of cotton. They had always been giving cotton too large a place, but their only idea of farming seemed to be the “making of a crop” of some kind to sell. Some wanted to go into broom corn, some into sunflowers for the oil, some into hops or some other crop about which they knew nothing, and many of which were entirely unsuited to the Southern climate, as the hop is. We have tried earnestly to impress on the writers that the only hope of the South lies in better farming with the staple crops we have, and an utter abandonment of the cotton cropping idea. “But I cannot afford to put my land in crops that will pay me less money than I can get from the land in cotton,” is what we are continually being told by men whose cotton costs them 6 to 8 cents per pound, when by better farming and the growing of forage and feeding of cattle they could grow the cotton for half what it now costs them, and this, too, with a more liberal expenditure for fertilizers than they now use, but used in a different way. WHAT IS THE BEST ROTATION FOR COTTON? Bulletin No. 43 of the Georgia Station makes the following statement in regard to the rotation practiced there. “At the beginning of the ex- istence of the Station, nine years ago, a regular system of rotation was in- augurated, and with occasional modification, it has been continued to the present time. ‘This system is what would be called a three year shift, and is as follows: First. year: Oats, liberally fertilized, followed by cow peas with 200 pounds of acid phosphate per acre. The cow peas, as a rule, were made into hay.° Second year: Cotton, liberally fertilized. Third year: Corn. At the beginning liberally fertilized, but later, mod- erately fertilized.. Cow peas were sown in the corn, sometimes in hills at second plowing, but generally broadcast at the third plowing. Peas gathered for seed supply. A part of the corn for several years past has been cut down, stalk and all, and put into the silo. After the corn, the land was again sown in oats in October or early November, thus commencing a second round of the three year rotation. The Director does not hesitate to say (and in this opinion he is sustained by the Agriculturist), that the increased productive- ness of the farm is due more to the adoption and maintenance of a regular system of rotation of crops, than to any one policy or practice.” The bulletin further states: “On most small farms that are devoted to cotton and corn and minor crops, and where very few animals are kept, there will not be more manure from this source than will be required by the kitchen garden and the COMMERCIAL FERTILIZERS FOR MAINTENANCE OF FERTILITY—107 truck and forage patches around the residence and barn. For the outlying fields, more or less remote from the house, reliance should be placed on the system of rotation already outlined, in which small grain and cow peas are leading features, aided by a judicious use of concentratetd fertilizers. As the system develops, and after it has been in operation a few years, the necessity for these concentrated fertilizers will be less urgent, a smaller quantity will be required, and increasing profits will accrue.” ' In the main there can be no great objection to the plan of the Georgia Station. What we do object to, however, is the statement that on small farms there will be proportionately less manure made than on a large one. If the rotation advised is followed, there will be a considerable amount of forage produced in the shape of oats straw, corn fodder and pea vine hay, and, whether the farm be large or small, this should be fed on the place, to cattle, and the result will be that there will be as much manure in proportion to the area under cultivation on the small farm as on a larger one under the three year rotation. A long experience in the culture of Southern lands has shown us that the great advantage of the three year rotation lies in the more frequent bringing on the soil of a leguminous feed crop, and the*practicability of finally making manure enough to broadcast one-third of the area annually. Dribbling a little manure around on the better lots about the barn will take a long time to restore the fertility of the farm, the produce of which is being used only on a limited area. The small farm is the place for the manure spreader with all of its manure-spreading economy. | In practicing a good three year rotation with cotton, and feeding all the forage grown, as well as the corn and oats, the cotton farmer can make live stock an important part of his profits while increasing his manure accumu- lation. Another point of importance in the Georgia rotation is the fact that every crop grown is supplied with commercial fertilizers in large or small quantity. At the usual market price for corn we have never been able to get back the cost of a complete fertilizer applied to this crop. The corn field is the place for the manurial accumulation of the farm, and a well arranged three year rotation will, in a few years, enable the farmer to make manure enough for his corn. Growing through the long heated season, when the nitrification is most active in the organic matter, corn can make a better use of the manure than any other crop, while at the same time there will be a residue well incorporated with the soil that will carry the oats through without the further addition of commercial fertilizers. Then with a more liberal appli- cation of acid phosphate and potash to the oat stubble the great nitrogen- collecting crop of the rotation, the cow pea, will make a great crop of forage, 108—Crop GROWING AND Crop FEEDING and leave in the stubble nitrogen enough to carry the succeeding cotton crop, with the aid of the seed made by the preceding crop, or the meal exchanged for the seed. For a few years in the first start of the improvement of a worn cotton farm it may be necessary to add some acid phosphate to the cotton seed meal; this, too, can soon be dispensed with, and the only commercial fer- tilizers that need be bought through the whole three years will be the acid phosphate and potash for the peas. When you reach this point cotton growing becomes profitable, even if the price goes lower than the ordinary cropper can grow it for. Your well fed cattle will pay all the expenses of your farming, and leave the manure and the cotton crop as profit. This is no mere theory, for it is being done successfully, and in the hands of some enterprising men the crop of winter oats has assumed an importance from the great crops grown that makes them, too, an important money crop. The way out of the slavery of the cotton farmer to the fertilizer mixer lies through the growing of forage and the feeding of cattle, and the working of his land in a systematic rotation contrived for the best success of the cotton crop through making the best success with the forage crops. A permanent pasture for summer is an important part of the improvement of a cotton farm. Fortunately there is the Bermuda grass, a plant admirably suited to the needs of the cotton farmer. It suits his soil, it suits his climate, and it grows in perfect defiance of heat, and will enable him to carry through all the cattle he needs for feeding in the winter. With a permanent pasture of Bermuda grass, the cotton farmer never needs to pasture his fields where his crops are grown, but can keep them at all times growing something either for sale or feeding. A profitable and practicable rotation, then, for a cotton farm, will be to begin with land that has yet to be improved and gotten into a more productive condition. First year: Cotton, with a good dressing of a complete fertilizer broad- cast, at rate of 400 pounds per acre. In September sow among the cotton 15 pounds per acre of crimson clover and one bushel of rye. If the clover fails, the rye will make a green cover crop to ward off waste in winter. During the winter get out and spread all the farm accumulation of manure on the rye and clover. Second year: Plow under the rye and clover with the manure for the corn crop. Turn them under deeply, and then work the crop rapidly and frequently, but perfectly level and shallow and avoid all earthing up with a plow. No turning plow should ever be allowed in the corn or cotton field. At last working, sow cow peas all through the corn. Gather your seed from these for the next year’s sowing. Cut the corn and cure in shocks and dise the peas over and sow winter turf oats. CoMMERCIAL FERTILIZERS FOR MAINTENANCE OF FERTILITY—109 Third year: Cut the oats and at once plow the land well and harrow in 300 pounds per acre of acid phosphate and 50 pounds of muriate of potash, and after a rain has followed the harrowing drill in one and a half bushels of peas per acre. When these are mature, and the first pods are turning vellow, cut them for hay and cure for feed. Disk the stubble over and sow Crimson clover in September to be plowed under for cotton in the spring. It will be well to sow a little rye as a shade to the young clover. With a good stand of clover and rye you will need little fertilizer for the cotton crop that now begins the rotation over again, but for a while it may be well to use a little acid phosphate on the cotton. One of the best plans for using the cotton seed is that devised by a good farmer in South Carolina. This is to bury the cotton seed in a furrow down the middles. If any seed sprouts it can easily be destroyed in the cultivation of the crop, and the seed will be rotted and ready to feed the plants when fruiting time comes and the roots are searching across the rows. After two or three rounds of this rotation you will find that the only place where you will need any commercial fer- tilizers is on the land to go into peas after oats. Year after year you will be getting more and more forage to feed cattle and can make more and more manure, till finally you will have no difficulty in getting enough to cover the corn-tend, if uniformly spread with the machine. And, better than all, you will have the cattle to bring in money in the spring, so that you can get upon a cash basis and reduce expenses through buying for cash. The general experience at the Stations in the cotton belt has been that the use of commercial fertilizers is of special value to the cotton crop in hastening its maturity, while in some instances the use of stable manure had the effect of delaying the maturing of the crop. The corn crop on the farm can use the crude manures from the stock to better advantage than the cotton crop, and by the time the land comes around in cotton again, the manure is better assimilated with the soil, and is in better condition to suit the cotton plant. In the continuous planting of cotton on the same land there has been noticed a cumulative effect from the previous dressings where these have been in liberal amount.. In Alabama and Arkansas it was found that nitrogenous manures increased the yield the second season without additional fertiliza- tion, but had lost their effect by the third season. In Alabama the phos- phatic fertilizers increased the yield for three seasons without further applications, and in Eastern North Carolina there seems to have been so much accumulation of phosphoric acid that acid phosphate no longer has any effect when applied as a fertilizer to most of the lands that are cultivated in cotton. In Alabama the application of pulverized rock phosphate, or what is commonly called “floats,” in which the chemist finds that the phosphoric 110—Crop GROWING AND Crop FEEDING acid is all insoluble, increased the yield for two successive seasons, and farmers are gradually finding out that this material, when placed in the soil, rapidly becomes soluble enough for plants to get the use of it, and since it can be sold for half the price of the dissolved rock it will be well for farmers to experi- ment with it, and see if the cost of fertilization cannot be further decreased. Several Stations report that the effect of kainit, or crude potash salt, is to prevent rust in the cotton, aside from the value the potash may have as a fertilizer, but it also seems to have the effect of retarding the opening of the bolls. In South Carolina it was found that the application of marl alone, or in connection with the commercial fertilizers, is of no direct value to the cotton crop. But when marl is used as an application to leguminous crops in storing up organic matter in the soil for the cotton, it has a very great indirect value. In Alabama it was found that air slaked lime mixed in the drill with acid phosphate had no apparent effect on cotton; in fact, it would seem that it might have an injurious effect in making the phosphate less soluble. Nitrate of soda has been profitably applied at two dressings between planting time and June 1st. Better results have been had from fertilizers worked in shallowly than those buried deeply for cotton. From the various experiments of the Stations, the Office of Experiment Stations reaches the following general conclusions, in regard to the cultivation and fertilization of the cotton crop, taking also into the account the experience of successful cotton growers. It is evident that cotton is a plant. that responds promptly, liberally and profitably to judicious fertilization. The practice general in the South we do not regard as judicious, since under it the productiveness of the land has gradually been decreased, until the soil is not in the best condition to apply lilberal quantities of commercial fertili- zers, by reason of the exhaustion of the humus supply in the soil, through the continuous planting of cotton aided by scanty supplies of fertilizers. But by judicious fertilization with these same commercial fertilizers in con- nection with proper farming, the maturity of the crop may be hastened and its period of growth shortened so as to materially increase the area northward where the cotton crop may be profitably grown. But this judicious use of fertilizers involves the antecedent preparation of the soil. A soil deficient in humus, or decayed organic matter, is not only in a-bad mechanical condi- tion, but is in a poor condition to receive liberal applications of commercial fertilizers, since it is more subject to drought by reason of the absence of the moisture-retaining humus, and_ hence, cannot dissolve the fertilizers. Therefore, the higher “tilth” we get our lands into, the heavier application of fertilizers we can profitably use. The culture of the cow pea as a renovating crop is essential COMMERCIAL FERTILIZERS “FOR MAINTENANCE OF FrRTILITY—111 in the cotton belt to the restoration of those new ground conditions which all planters have noticed are so favorable to the profitable culture of cotton. On lands newly cleared from the forest every cotton farmer has noticed that the crop is not only more certain without the fertilizers, but that a heavier application of fertilizers can be more profitably made than on an old field that has so long been in the crop that it has lost the black humus that the new land has so plentifully. Therefore, the effort of the farmer should be towards the keeping up of these soil conditions where they exist and the restoration of them where they have been exhausted, and in no way can this be done so economically as through the culture of the “clover of the South,” the cow pea. Not that the cotton farmer should sacrifice a valuable feed crop as manure direct to his land, for the cutting of the hay and the feeding of it to stock is far more business-like and profitable than the burying of the whole growth at once in the soil. The roots and stubble contain a large amount of the manurial value, and by saving the manure carefully the land loses little of the tops, while feeding can be made an important part of the farm profits. Barnyard and stable manures are more profitable to the cotton planter, as a means for the bulking up of his soil with organic matter, and for the forma- tion of the important humus, than as manures direct to the crop; for we have seen that crude manures may tend to delay the ripening of the crop. Drib- bling a little manure or compost of manure in the row is not the best way to get a stand of cotton, and is far from being the best way to improve the soil. All home-made manures, and all woods-mold collected, should be spread broadcast over the whole soil. As we have said, the place for these crude manures is on the corn crop following the cotton and preceding the oats or wheat, so that by the time the field comes around again in cotton, in a three- year rotation, the remaining manure has been reduced to a state of humus and aids the commercial fertilizer applied to the cotton crop in doing its work. The editor from whose work we glean these conclusions, says that cotton may be wisely assigned a place in a judicious rotation, and suggests a rotation of small grain, followed by corn with peas, and then cotton; and adds that each crop should be properly fertilized. To this rotation we see the objection that there are no peas for mowing and making hay for stock, and no mention of making manure. Now, as the feeding of live stock is at the very foundation of all rational farm improvement, in the cotton as well as the corn field, the rotation that does not provide a _ forage crop other than corn is defective. Then, too, while an application of fertilizer to every crop grown may produce an increase of the crop, it is not always profitable farming. One of the chief values of a good rotation, to my mind, is to enable the farmer to increase the productiveness of his 112—Crop GROWING AND Crop FEEDING soil, while gradually using less of the purchased fertilizer, until he needs to buy none but phosphoric acid, and perhaps potash, and these for the pea crop alone; for by a proper rotation and the production of a plentiful supply of forage crops, that will go to make together a balanced ration for cattle, he can supply his soil all the nitrogen needed; and éan accumulate fertility in the land till his money crop is produced in its highest excellence, without any direct application of commercial fertilizer. The investigations of the Stations in the study of the manurial requirements of the various crops, have had the effect of getting farmers to think that for every crop planted they must have a special fertilizer. Good farming with cotton or any other crop does not mean merely the production of large crops; but in the production of crops at the lowest possible expense, while increasing the fertility of the soil. It is not good farming to teach farmers that they need make an application of fertilizer to every crop planted, and we will never get them to see the value of a rotation, till we show that a rotation can do what we have said is good farming. One of the labor-wasting practices long in vogue among cotton farmers in the South, is what is called composting. Having but little manure from the few cattle kept, and that of poor quality from the poor and scant feed, they go to work to haul a lot of soil from woods and fence rows and mix with the manure, and turn and chop it down with the notion that they are making the whole good manure. And then this laboriously made pile of dirt, is dribbled in a parsimonious way, in the furrows under the cotton ; the only use it has being to enable the plant to use better the fertilizer they add to it. It takes our farmers a long time to realize that it is far cheaper to grow the organic matter all over the soil, ready spread, than to pile and turn it and haul to the field; and that far more of it can be grown there than can be hauled there by any one. The rotation we prefer for a three-year rotation with cotton has already been given, and the experience of those who have adopted it has abundantly proved its correctness. While in the first stages of the building up of a poor piece of cotton land, it may be advisable to apply some fertilizer to each crop planted, the farmer who strictly follows the three-year rotation we have given, will soon find that all the commercial fertilizer he needs to buy will be acid phosphate and potash for the peas, and the peas will do all the rest, if they are properly fed to stock ; while, at the same time, they are feeding the soil direct. Our Editor of the Office of Experiment Stations further says, that, on the great majority of the soils of the Cotton States it is advisable to use as a concentrated fertili- zer, a complete manure; that is one containing soluble phosphoric acid, available phosphoric acid and available nitrogen, rather than a manure containing only one or two of these ingredients. This may be true if the COMMERCIAL FERTILIZERS FOR MAINTENANCE OF FERTILITY—113 farmer is to continue to grow cotton continuously without rotation, but it is not true for the farmer who feeds stock and grows forage to feed them with from the cow pea and the corn plant. In fact, what a farmer should use will depend on the nature of his soil, for, as we have already seen, there is a considerable district in Eastern North Carolina where phosphoric acid is not needed in the soil, and there are other districts where potash is needless, while in all the cotton belt the nitrogen needed can be had in larger quantity and more cheaply in the cow pea than in a commercial fertilizer. While analysis may show that the cotton plant needs a complete fertilizer, this does not show that we need buy all the constituents of such a fertilizer, for all our soils and all conditions of culture. The editor well adds, afterwards, that the nitrogen may be omitted where it is supplied through animal manures, or what he in the language of the press calls green manuring. And right here I would repeat what I have often said, that what is called in Northern latitudes “green manuring,” is not applicable to Southern con- ditions. In the cooler climate of the North and the heavy clay of the glacial drift, it may be practicable to plow under green crops; in the sandy soil and warm climate of the cotton belt, such a practice would be simply suicidal to the interests of the cotton farmer, for he would not only sour his soil, but he would cut short the work the legumes are doing for him before they had fairly completed it. Hence, for the South at least, we should drop entirely the misleading phrase “green manuring,” since no such practice is applicable to Southern conditions. But while green manuring cannot be practiced in the South as it is in the North, there is an even greater need for the growing of the green manure crops, for the purpose of getting forage and making manure, and for getting the nitrogen collecting work of the legumes completely done. While soluble phosphates, like acid phosphate, are best for their immediate effect on the cotton crop, there seems to be no doubt that the insoluble floats may be profitably used after a while in the promotion ef the growth of the pea crop, and to accumulate there for the use of the cotton crop, that should follow the peas. Kainit, muriate of potash and sulphate of potash present the potash to the cotton plant as fertilizer in an equal manner, and the only difference is in the cost. Kainit, while of special value aside from its use as a fertilizer, in that it has a tendency to prevent blight, is, in most places, the most costly form, since it has but 12 per cent. of potash, and its use involves the freighting of a large amount of useless material; while the muriate has 50 per cent. of potash and a smaller quantity need be freighted to get what potash we want. As a nitrogenous manure for cotton, the cotton farmer can usually get all that he needs by exchanging his cotton seed at the oil mill for meal and hulls, and while he may use, if 114—Crop GROWING AND Crop FEEDING he chooses, a little nitrate of soda as a starter for the cotton, the organic nitrogen will usually be the best form for the sustenance of the crop during the season. Therefore, it is more than ever apparent that the organic nitro- gen from the pea roots is the best form of nitrogen we can get. Much work has been done by the Stations in the Cotton States in the study of the propor- tions in which the various constituents of a complete fertilizer should be used. In Georgia they claim that the proportion should be nitrogen 1, potash 1, phosphoric acid 3144. In South Carolina, nitrogen 1, potash %4, phosphoric acid 214; while in North Carolina, where in a large part of the cotton belt phosphoric acid is not needed, the law requires that a complete fertilizer allowed to be sold must not contain less than 8 per cent. of phos- phoric acid. This law is about to be changed now, however. Quoting further from the Office of Experiment Stations we find it stated that the amount of concentrated fertilizer which may be profitably used per acre on the cotton crop, varies widely with the nature and condition of the soil, the seasons and other circumstances. For an average soil in fairly good con- dition, perhaps the maximum amounts indicated in Georgia—nitrogen, 20 pounds, potash, 20 pounds, phosphoric acid, 70 pounds, or South Carolina —nitrogen, 20 pounds, potash, 15 pounds, phosphoric acid, 50 pounds, or an approximate mean between the two, would be the maximum limit of the profitable application. This would mean the application of over 800 pounds per acre of an average cotton fertilizer, an amount which, if applied to the worn uplands of the cotton country, would do more harm than good, but which can be used only on soils of a moist nature and well supplied with humus. While 700 to 800 pounds of a complete fertilizer may be used on such lands, the larger part of the old lands of the upland country, in the Cotton States, could not safely apply more than half that quantity, until through good farming and the accumulation of organic matter in the soil they have prepared the land to receive such a liberal dressing. Quoting from the same source we find it stated that the concentrated fertilizer should be applied in the drill and not broadcast, at a depth of not more than three inches, and well mixed with the soil. To the first part of this statement we have a serious objection, and there is every reason why the fertilizer should be applied not alone in the drill but broadcast. Cotton spreads its roots far and wide, and as the feeding roots’ hairs are out near the tips of the roots they soon get away from the little that is directly under them and are foraging in a poor soil, so that at the most critical time of the crop, the fruiting time, the plants have less food at their command than at any other time. Then, too, if as large an application as 700 to 800 pounds per acre of a complete fertilizer is used, the application in the drill alone of that COMMERCIAL FERTILIZERS FOR MAINTENANCE OF FERTILITY—115 amount would probably be disastrous to the getting of a stand of cotton, for it would burn the roots up. Then, further, it is stated that all things con- sidered, it is best to make the application all at one time, that where the land is in superior condition and a large application is used it is probably profit- able to apply half at planting and half at the second plowing. Then this second half would certainly not be in the drill, but would be just where we would have put it in the beginning, in the middles of the rows. We have quoted thus largely from a review of the work of the Experi- ment Stations in the Cotton States, to show that the experimenters themselves have not been able to get away from the old traditions of the cotton field. They have done a great deal of work in determining the food requirements of the cotton crop, but are as badly in the ruts in regard to the culture of the crop as the planters themselves. All the old practice of fertilizing in the furrow and making a bed of soil above it, plowing first, second or third times, are all relics of the old ruts from which it is time cotton growers were get- ting out. Fertilizing in the furrow is not the way to bring up the pro- ductiveness of the land for any crop. Deep preparation of the soil, planting on the flat surface, and then shallow and _ perfectly flat culture should be the rule. There is no more need for a plow in the cotton field after the crop is planted than there is in a corn field, and the methods that are best for the one are of equal advantage for the other. Cotton was grown here the past season on well prepared land perfectly flat. It was cultivated with a smoothing harrow and a weeder till over six inches high and then with a small tooth cultivator the rest of the season, and never hilled in the slightest degree; and that cotton went through a season of un- precedented drought and heat better than any plowed and hilled cotton around it. Then, too, the everlasting directions that have been given the farmers about the particular amount and kind of fertilizer that should be used have confused them to such an extent that they think that all they need is a formula for the preparation of a fertilizer. There is much need of ener- getic work on the part of the Stations in the Cotton States to show the farmers the best methods of improving their soil for the production of the cotton crop, and the means through which they may be relieved from the necessity of buying a complete fertilizer for every crop they plant. Good farming is needed more in the Cotton States than any more knowledge re- garding fertilizers, for those who get to doing good farming will naturally use what fertilizers they need in a more liberal manner. Then again, the experiments in fertilizers with any crop on the soil of the Experiment Station, at one point in a State as large as Georgia or North Carolina, can hardly be of much use to a large part of the farmers in those States, who are growing 116—Crorp GROWING AND Crop FEEDING cotton on a different soil, and to give to farmers the proportions in which they should mix their fertilizers to make a complete cotton fertilizer is pure quackery, and should not be indulged in by men engaged in scientific investi- gation. The methods of culture need more improvement than the fertiliza- tion of the crop, for these are the same they were a hundred years ago, and the everlasting fertilizer investigations at the Stations are only keeping up the old practices. The Southern cotton grower needs to be taught more about eeonomical methods in farming than he does about mere application of fertilizers, and he needs to be taught the most economical, and at the same time most liberal, way to use these fertilizers, in the building up of his soil rather than in the squeezing out of a little more sale crop. CURING THE PEA VINE HAY. In farming for cotton in this way, the pea vine hay is an important item. There has long been a notion that the vines are hard to cure. We have proved year after year that there is no hay more easily cured, and none better for any stock kept on the farm, from the pig to the horse. The methods in common use heretofore in the South have usually resulted in the loss of the leaves, the best part of the hay, and in the production of a mass of hard sticks, instead of the hay that can be made. We have time and again given our method of managing the hay crop. It is hard to give directions that will fit all conditions of the plant, and the weather. Peas that have grown rankly on fertile soil will make great, thick stems that are more slow to cure, and in such case the sowing should be made thicker so that the stems will not get so stout. Ordinarily one bushel of seed per acre is enough, but on strong land, where they are apt to grow too rank, the seeding of one and a half bushels per acre will make a finer hay. When the first pods are turning yellow, but none dry, cut the hay with a mower with the track marker off. If the weather is bright and warm, let them lie for 24 hours and then rake into windrows. Next day turn the wind- rows in the morning and dry them off. If the weather is still hot, the hay may get dry enough to haul in that afternoon. The test as to its dryness is to take a handful and give it a hard twist. If you can see no sap run to the twist it will do to go in the barn, provided there is no external moisture on it.- Store in as large a mass as possible, and the tighter the barn the better, but it will cure in a rather open barn. While curing in the barn do not disturb it on any account, as you will cause it to mold if you let the air into it while hot. Let it strictly alone and it will cure all right, will be per- fectly green in color and sweet for the stock. Now this is no theory, for we COMMERCIAL FERTILIZERS FOR MAINTENANCE OF FERTILITY—117 do it every year without a failure, and yet we have had farmers write that their hay molded. I suppose it requires some judgment and experience, but I have tried to give the method that has been a success with me, and can see no reason why it should not be a success anywhere. If rain falls on the hay in the field, spread the windrows and dry off well before housing. Rain will do little damage, far less than it would to clover hay, but it will darken it and should be avoided if possible. Once catch on to the right way and you will have no difficulty in making the finest hay in the world. Farming for cotton without the cow pea, the clover of the South, will always, on our worn uplands, be a losing business. RESTING THE LAND. There has long been a practice in the cotton country of “resting” the land, by allowing it to grow up in weeds and grass each alternate year. Feeling that constant annual cropping in cotton was bad, the farmers came to the conclusion that the soil was “tired,” and needed a rest. Of course the accumulation of organic matter through the idle season added a little to the land, and the resting was better than the constant culture without systematic rotation. But intelligent farmers all over the South are rapidly learning that the best way to rest land is to keep it at work growing some- thing of value between the sale crops; something that will help recuperate the land better than a crop of weeds, and the wise farmer now keeps all land, vacant of crops in Summer, covered with peas. ANOTHER COTTON ROTATION. We have given what we consider the best rotation for a large part of the coast country of the South. But there is a large section of the upland red clay country where cotton is still the money crop, and where wheat flourishes well. There the same three year rotation can be made a success by putting wheat in the place of winter oats. But where both crops are wanted, the rotation can be extended to four years and another crop of pea hay gotten in. In this case the peas after oats will ‘be followed by wheat, and this again by peas fertilized with potash and acid phosphate, preparatory to the crop of cotton. One of the chief ideas in a rotation is to keep the land covered as much as possible by growing crops. Our Southern soils have lost fertility as much by lying bare in the winter as by the summer cropping. Never let the land lie all winter without some green cover crop. This will not only add humus-making material to the soil, but it has been found that 118—Crop GROWING AND Crop FEEDING where the land is covered with green plants in winter there is little if any loss of nitrogen, but where it les bare there is a great leaching of nitrates. A cover crop is of far more importance in the South than in the North. Here we have more rain than hard freezing, and the soluble nitrates are rapidly washed out of the bare soil. What we would especially impress on the cotton farmer is the fact that thorough preparation of the soil, clean, flat culture and a good rotation, are far more important to success than the kind and amount of fertilizers he may apply to the crop. I would like to help the Southern farmer out of the slavish dependence on fertilizers, merely for the purpose of getting a little more out of the soil to sell, and to show him that the true place for the plant food in the fertilizer is where it will en- courage the crops that feed his stock, and through them feed his farm. Used in this way you may use the fertilizers liberally, and in no other way do they so well supplement the home-made supply of manure. We hear a good deal about making the manure go as far as it will and then supplement it with fertilizers, but the true way to supplement the manure is to use the fertilizers for the manure-making crop. The phosphoric acid and the potash are then retained on the farm and their use enables you to get a far greater supply of the costly nitrogen. A very intelligent South Carolina gentleman recently wrote to me: “You are continually urging our farmers to grow more peas and to cure them for cattle, but you overlook the fact that they have not the cattle to feed them to, and they have not the fences to enclose the cattle ;” and he might have added that in their single cropping they have gotten so dead poor that they cannot buy the stock nor build the fences they need. But even to these men the pea will bring help if not utilized as it should be, for we must never lose sight of the fact that the great value of the pea in the South and of clover in the North, lies in the accumulation and maintenance of humus in the soil, and that the greatest value of humus, aside from its furnishing some nitrogen, lies in its making the soil more retentive of moisture, and thus enabling the farmer to use commercial fertilizers more profitably. The most successful cotton farmers we know are the men who are growing cotton on the level black lands of Eastern North Carolina. These men are able to use an amount of fertilizer per acre that would be destructive to the cotton farm on the dry uplands. They apply from 600 to 800 pounds per acre of a complete fertilizer, and claim that they make it pay. They certainly grow fine crops. They are able to use this amount of fertilizer because of the superior capacity of their soil, which is well supplied with humus, for the retention of moisture for the solution of the fertilizers applied. Hence the plants get the use of it in the best manner. The single cropper on the COMMERCIAL FERTILIZERS FOR MAINTENANCE OF FERTILITY—119 uplands could not grow the crop the coast farmer does with any such appli- cation. The chances are that he would burn his crop instead of benefiting it. This is because his soil has lost its humus and lacks the capacity for the retention of moisture which the low farm has. Here, then, hes the secret of the improvement of the upland farm; the growing of the pea purely for the benefit of the soil, even if not fed, as it should be, to stock, for through its agency he not only gets added fertility from the air but added capacity for using increased applications of fertilizers; for it is a fact that the use of fertilizers is more profitable on a fertile farm than.on a dead poor one. The past hot and dry summer was one of the most remarkable illustrations of the truth of this we have ever seen. All over the State on the thin and dry lands the crop was remarkably short, and the fertilizers applied were almost entirely wasted by reason of the fact that the plants could not get them in the dry soil. But here and there were men who have been practicing pea culture for the benefit of their land, and have thus increased its moisture retaining character, who made a good crop and got the benefit of the fertilizers they applied to the crop. It is evident, then, that even where the cotton farmer is not wise enough, or is not able to feed stock, the peas are still the best means he can employ for the improvement of his crops and the maintenance of the pro- ductivity of his soil. CHAPTER XIII. WHERE WINTER WHEAT IS THE MONEY CROP. A study of the manurial requirements of the wheat crop, at more than one Station, have shown that potash applied alone to the crop, has, on a typical wheat soil, hardly any appreciable effect. At the Virginia Station it was found that nitrogen gave some increase of yield, but not enough to pay the cost of the application. That potash and nitrogen applied together gave no better results than when apphed separately. Their combination was in- ferior to the results obtained from a separate application of phosphoric acid. Phosphoric acid doubled (or more than doubled) the yield of straw and grain every year, and gave profitable returns. In combination with either potash or nitrogen it was unmistakably effective. It gave better results in combination with nitrogen than with potash. These experiments were made on a fertile limestone-valley soil. The Delaware Station found that the combination of phosphoric acid and potash was most effective on their soil. Many years ago the farmers in the upper counties of Maryland and Delaware, on the Peninsula, found that on their soil they got as good returns in the wheat crop, from the simple application of acid phosphate, as from the use of a complete fertilizer, when they used a short three year rotation. For many years, in the finest wheat growing section of Maryland and Delaware, hardly any fertilizer except acid phosphate, has been used by the best wheat farmers. The Delaware Station has tried to show them that a small addition of potash would be an advantage on their soil. But few have been induced to change their practice. An old and intelligent farmer of Queen Anne county, Maryland, recently wrote to me that he had used no other fertilizer than simple acid phosphate, for twenty or more years, and that with his rota- (120) WHERE WINTER WHEAT IS THE MoNEy Crop—121 tion the wheat crop had steadily improved, and he said that now his last crop was 40 bushels per acre. I have seen, the present Summer, lands in Mary- land on which 50 bushels of wheat per acre were grown the present season, where no nitrogen has been bought for many years. _ The wheat farmers of Maryland have learned that they can get all the nitrogen they need without buying it in the form of a commercial fertilizer. And this is a lesson for wheat farmers in all parts of the country where winter wheat is grown. The important thing to the wheat grower is, while getting a fair growth of straw to avoid an excessive growth, but at the same time a full crop of grain. An excess of nitrogen tends to an excessive straw growth and a consequent weakness and liability to lodge. While all the studies of the manurial requirements of the wheat crop show that the greatest yield is where there is applied a complete fertilizer, with a due proportion of phosphoric acid and nitrogen and potash, it by no means follows that it is necessary to buy all of these in a fertilizer. We should also bear in mind the fact, that on a soil where legumes have not been regularly grown in a rotation, some years must elapse before the nitrogen col- lecting crop will gather more than is needed by the immediately succeeding crop, unless further addition of nitrifying organic matter is, in the mean time, added to the soil. Hence a short rotation again comes in as the best under most conditions. ROTATIONS FOR THE WINTER WHEAT CROP. For many years, and long before the use of commercial fertilizers became general, the best farmers of the Middle Atlantic States, whose money crop is wheat with stock feeding, practiced a rotation in which the land was seeded to clover and grass with the wheat, mowed for several years and then pastured, and finally the sod plowed for corn, which was followed by oats the following Spring and the oats stubble fallowed and prepared for wheat again. Keeping a large number of cattle and raising a goodly quantity of manure, these farmers managed to keep their lands to a fair state of productiveness, with a long rotation, on farms divided up into very small fiefds with a vast amount of needless fencing. ‘This practice has since gradually given way to a four year rotation, with clover standing but one year, and the land again returned to corn. The fault of this rotation is that the important money crop, the wheat, comes on the oats stubble, and nearly two years after the clover has been plowed under, hence does not get the best use of the clover. The Delaware Station proposes to remedy this by introducing there the early varieties of the Southern cow pea, after the oats are cut, as a preparatory 122—-CroP GROWING AND Crop FEEDING crop for the wheat. In sections hke Delaware, where winter oats can be suc- cessfully grown, this plan will probably be a success; as the winter oats should there come off the first of July or earlier, and give plenty of time to make a crop of peas, from the varieties, like the Warren Extra Early, which will make a matured crop in 60 days from the sowing. ‘The rotation would then be, wheat, with a good application of acid phosphate and seeded to clover. Clover mown twice, or once and pastured. Home-made manure hauled out on the clover sod during the winter and all plowed under in the spring for corn. Oats sown in September and followed by peas cut for hay, and stubble prepared for wheat again, with acid phosphate. This will give two nitrogenous forage crops every year and largely increase the feeding capacity of the farm. In other sections, where the oats crop is of less importance, great success has attended the use of a three year rotation of corn, wheat and clover, the only fertilizer used being acid phosphate on the wheat, and an occasional dressing of lime on the sod for corn. It may be argued that the corn stubble is not the most favorable place for the wheat, and under former conditions it was not. But where the farm is stocked to its full capacity for feeding cattle, and a large amount of manure is made and apphed broadcast to the corn crop, the corn stubble, with the help of acid phosphate, is not an unde- sirable place for the wheat crop; as is evidenced by the regular increase in the wheat crop where this rotation has been practiced. As in the three year rota- tion with cotton, this can be best carried out with the aid of a permanent pasture, and thus save all interior fences on the cultivated land. In all the rolling uplands of the Upper South, in North Carolina, South Carolina and Georgia, there are elevated lands that the owners have persisted in growing cotton upon which are naturally better adapted to wheat. Some years ago, when traveling through the upper section of South Carolina on the Southern Railway, a gentleman, evidently a farmer, boarded the train, and as I am always interested in talking with the farmers I picked up an acquaintance with him and made some inquiries about the country through which we were traveling, between Spartanburg and Atlanta. I found that my friend was’an intelligent farmer, who had come there from a wheat grow- ing section in the North and had been farming for a number of years in this Piedmont section. He said that having been a wheat grower all his life, he determined to continue to grow wheat and clover, as he could not see why they should not thrive in that elevated and beautiful section. He said that the first year when he sowed wheat he was laughed at, and told that wheat would not make much of a crop there. He made, the first year, only 6 bushels of wheat per acre, but as his land was in a badly run down condition 7 WHERE WINTER WHEAT IS THE MONEY Crop—123 he was not surprised at this and simply kept on following a rotation which he had planned for the improvement of the land. Last season he said that his wheat crop, on the same field that once made 6 bushels per acre, was 35 bushels per acre, and that he was satisfied that wheat could be as successfully grown on the Southern uplands as anywhere. But this farmer had been wise enough to adapt his farming to the conditions of his environment. He had found that in the sunny South red clover is a very uncertain crop, and that its place could be well taken by the Southern pea. Accordingly he had adopted a rotation in which the pea took the place of clover, and enabled him to make more crops in a short rotation than he could with clover, which remained on the land a whole year. His rotation was corn, with peas planted among it and all the manure of the farm applied to it. Corn cut off at the ground, cured in shocks and the stover all saved for feed. Land well disced, the peas chopped up, and winter oats sown. Next spring the oats are har- vested and the land at once prepared for peas, with a dressing of acid phos- phate and potash. Peas are mown for hay and the land again disced only, and the surface made fine and sown to wheat. After the wheat is harvested the land is plowed and peas sown again and another crop of hay made. Rye is then sown as a winter cover, and during the winter the manure is gotten out, spread on the rye and all turned under in March for the corn crop; and the rotation begins again. At first he found that it was better, in the poverty stricken state of his soil, to plow under all the meagre growth of peas for the wheat and corn, but later on, as the growth became heavier, he found that this would not only be a waste of feed, but that the land could not be so well prepared for the wheat crop. He then got to feeding more cattle and utiliz- ing the forage he was growing so largely, and found that the feeding was a profitable part of his farming; and that his land was constantly improving while the farms around him, which were being worked in the old way, in cotton alone, were washing and wasting. There is no reason, however, that a similar rotation should not be fully as good for those upland farmers who wish to adhere to the cotton crop. In their case the rotation could be made, corn with all the home-made manure, followed by wheat, with commercial fertilizer without nitrogen, peas after the wheat is cut, and these made into hay, and rye sown on the stubble as a winter cover, and plowed under in early March for cotton. Commercial fertilizers used on the cotton, and crimson clover sown among the cotton in September. Then, during the winter, get out all the farm manure on the clover, and in March plow all under for corn and begin the rotation over again. In this rotation, the wheat, coming directly after the corn, to which the manure and clover was applied, will have the best chance, will need no fertilizer except acid phosphate; the cotton fol- 124—Crop GROWING AND Crop FEEDING lowing the peas and with rye plowed under, will need only acid phosphate and potash, with perhaps a small percentage of nitrate of soda, to give it an early start. Then, if the peas and corn and corn stover are utilized in the feeding of stock, there should, in a few years, be manure enough raised to cover the entire corn tend. In this connection, though not directly in regard to wheat growing, yet in this same line of soil development through the feeding of the abundant forage that every Southern farm will produce, I would call attention to the results obtained at the Tennessee Agricultural Experiment Station, connected with the University of Tennessee at Knoxville. The Tennessee Station has made a series of experiments in the feeding of cattle, primarily to determine whether the native stock of the country could be fed at a profit for beef, and in the second place to determine whether a home grown ration could not be made to profitably replace feed that they would have to buy. They used, in the experiment, two groups of four steers each. The experiment began on the first day of January, 1900, and continued uninterruptedly for 98 days. The first group were fed all the shredded corn stover they would eat and also 6 pounds of cow pea hay and 3 pounds of corn meal. The second group were also fed corn stover ad libitum, and for part of the time had 6 to 16 pounds of cotton seed bran and 4 to 7 pounds of cotton seed meal, and then were changed to 6 pounds of the cotton seed bran, 3 pounds of cotton seed meal and 4 pounds of corn meal. The cotton seed bran is the finely ground cotton seed hulls, which is being largely advertised in the South for cattle roughage. But the experiment showed that it has little food value, is heavy and indi- gestible, and does not answer for roughage as well as the crude hulls them- selves; and these, in our opinion, are little better than pine shavings. These rations were gradually increased, until, at the close, the first group received 10 pounds of cow pea hay and 11 pounds of corn meal, and the second group had 7 pounds corn meal and 5 pounds of cotton seed meal. Without enter- ing here into the details of the experiment we give the conclusions arrived at: 1. Tennessee is admirably adapted to the production of stockers, which can be successfully fed on the products of the rich valley farms. 2. Stock husbandry has valuable effect on soil fertility, as 90 per cent., and over, of the fertilizing ingredients in the foods consumed, are available for the restoration of soil fertility . 3. Cotton seed bran is too expensive for roughage and has an unfavorable effect on digestion, producing impaction of the rumen. Tennessee farmers cannot afford to use it in this form, and all the roughage needed in cattle feeding can be produced more cheaply on the farm than anywhere else. 4. Cow pea vine hay made an admirable substitute for cotton seed meal. As it is not so rich in protein, however, it should be fed at the rate of two to WHere WINTER WHEAT IS THE MonEy Crop—125 three pounds of the former to one of the latter. 5. It is seen from these tests that a home grown ration of shredded stover, cow pea vine hay and corn meal, can be fed with success to a fair type of native cattle. This means much to the farmers of Tennessee. Tennessee is admirably adapted to the production of the cow pea. On good land two tons of this plant can be produced per acre, yielding 431.6 pounds of protein, costing 4.63 per pound. Besides this it stores up in the soil nitrogen which it gathers from the air. In view of its value in feeding it should be cultivated much more extensively for this purpose. 7%. Cotton seed meal gave the better results when combined with corn meal, in proportion of one pound of the former to one and a quarter pounds of the latter, than when fed alone. 8. This experiment indicates that native steers can be successfully fed at home at a fair profit. It further indicates that all the corn stover now wasting in the fields should be shredded and fed. 9. The tables bring out the importance of individuality in the animal, and show the necessity of improving our feeding stocks by crossing with pure bred sires. 10. The results of this experiment favor the use of a ration of corn stover, cow pea vine hay and corn meal, in preference to one of shredded corn stover, cotton seed bran and cotton seed meal. 11. Con- formation and uniformity of type are important in cattle feeding, as they materially affect the selling price. 12. The average gain in live weight in group one was 1.99 and in group two, 1.75 pounds per day. The best individual gain was. 2.50 pounds, and the poorest, 1.53 pounds. 13. The average cost for food for group one was $9.25; for group two, $12.63, a dif- ference of $3.38 in favor of home produced rations. 14. The net cost of a pound of gain with group one was 2.65 cents; with group two, 4.21 cents. This was chiefly due to the difference in market prices of the foods fed. 15. Group one consumed an average of 7.70 pounds of dry matter; group two, 9.32 pounds; group one consumed an average of 5.2% pounds of digestible matter and group two, 5.10 pounds of digestible matter for a pound of gain. 16. The average amount of water consumed by group one per day was 42.90 pounds, and by group two, 43.51 pounds. The highest amount consumed by any one individual was 50.36 pounds, and the lowest, 39.09 pounds. 1%. The average live weight of group one was 956 pounds, and of group two, 950.2 pounds. The average dressed weight of group one was 527.6 pounds, and of group two, 529.5 pounds. The percentage of valu- able meat in group one was 55.75, and in group two, 55.52. The highest percentage of valuable meat with a single individual was 59.13 and the lowest 53.56. This is considerably below the standard for good cattle, but a single cross would materially improve these results. 18. The average net increase by feeding was $8.37 with group one, and $7.71 with group two. 19. The 126—Crorp GROWING AND Crop FEEDING average cost of a pound of gain was 4.82 cents with group one, and 7.12 cents with group two. 20. The average net gain, allowing for care at 3 cents a day, was $6.15 with group one and $3.62 with group two. The average net gain, less care, was $8.98 with group one and $5.93 with group two. We have given these results here in full for*the purpose of showing that in other sections of the South, where the cow pea flourishes far better than in the upland country of East Tennessee where these experiments were made, farmers can produce an abundance of the finest of cattle food, and can, in the feeding of beef cattle, make a larger profit than most of them are now making with cotton; and can, at the same time, be growing a crop that will improve their soil for the production of cotton and other crops. While we appreciate the great value of commercial fertilizers as fully as anyone, we cannot too often repeat that the feeding of stock lies at the beginning of all rational farm improvement, either in the North or the South; and the sooner the Southern farmer learns the wonderful advantage he has in the cow pea the sooner will permanent prosperity dawn upon him. If the feeding of native cattle on the foods so easily produced in all parts of the cotton belt can be made profitable in Tennessee, it can be made even more profitable in the soils of the Atlantic border where the cow pea flourishes far better than in Kast Tennessee. To one who has studied these things through long years of farm experience it is amazing to note how slow the farmers are, not only in the South, but throughout the wheat growing section of the Middle States, to seize upon the means that will enable them to prosper as they have never done. The experiments at the Tennessee Station simply corroborate those made at the Delaware Station in feeding cow pea hay to milch cows as a substitute for the bran the dairymen are continually buying. It was shown there with cows, as it was with the beeves at the Tennessee Station, that the protein needed in a ration can be more cheaply supplied by the cow pea than by purchased food; for it was shown in Delaware that cows that had been for a time fed on a ration in which the protein was furnished by the bran, did not shrink in milk when taken from that to one in which cow pea hay furnished the protein, but that when they were put back from the pea vine hay to the bran again, there was a shrinkage in the milk yield. ‘The significance of these results to the wheat grower in the Southern and Middle States is plain. It shows that while improving their soil through the grow- ing of the pea, they can at the same time produce a food that will take the place of costly purchased food, and will enable them to turn out the finished products at a far less cost and consequently at a greater profit. The cotton grower may imagine that he can do without stock, but the wheat grower who does not keep and feed cattle is even more shortsighted than the cotton man. WHERE WINTER WHEAT IS THE MONEY CRoP—127 FERTILIZERS FOR WHEAT. It will not do to assume that because in certain sections the farmers have succeeded in greatly increasing their wheat crops through the use of phosphatic fertilizers only, that the same practice will insure success on all wheat soils. Asa rule, most of our best wheat soils of the winter wheat sec- tion of the Atlantic slope, are not deficient in potash to the extent that they are in phosphoric acid. It is these two which most concern us, for, no matter what the soil, a proper rotation with legumes will give us all the nitrogen needed by the crop. But every farmer, no matter what his crop, should find out for himself what his land especially needs. He must be an experimenter if he hopes to farm successfully and economically. How these experiments should be made will form the subject of a special chapter. Lime, of course, is useful in wheat farming, but we do not class lime and plaster as fertilizers, but as reagents, for bringing about chemical changes in the soil. The place for lime in the three year rotation for wheat is on the clover that is to go in corn the next season, and the time to put it there is in the early spring of the season in which the clover is to be cut. Once in six years is often enough to use lime unless the application is very light. But we would use phosphoric acid, or phosphoric acid and potash, on the wheat, not only for the benefit of the wheat but for insuring a better stand and growth of the clover. The practice of using the farm manure as a top dressing for the wheat in winter, may be a good practice in some cold sections as a pre- ventive of winter killing; but, on strong land, it tends too much towards the getting of a rank growth of straw at the expense of grain, and increases the danger of lodging. The place for all the farm manure is on the sod that is to be plowed for corn in the spring. During the summer’s cultivation of the corn crop it gets mingled with the soil, and much remains untouched below, to feed the wheat that follows the corn. In the more northern section of the winter wheat belt it is doubtless necessary to put the wheat in earlier than corn land will allow, and there a longer rotation is needed. WHAT A CROP OF WHEAT REMOVES FROM THE SOIL. An average good crop of wheat of 20 bushels per acre, will remove from the soil in the grain alone—and this is all we need be concerned about since the straw will go back to the land—28.32 pounds of nitrogen, 10.68 pounds of phosphoric acid and 7.32 pounds of potash. It will be seen, then, that the relative importance of these food constituents is pretty much as they stand. But, so far as the nitrogen is concerned, we will have left over in the 128—Crop GROWING AND CROP FEEDING organic matter of the clover and manure applied to the corn crop in a three year rotation, all the nitrogen the wheat will need; and we need but con- sider the needs of the crop as regards the phosphoric acid and potash, and to ascertain what the needs of the soil are as regards these. The maturing of the seed of the plant draws more heavily on the phosphoric acid in the soil than it does on the potash, and hence the relative greater importance of the phosphoric acid in the fertilizer. Then, too, we find that in order to get best results from an application of potash it is essential that it be accom- panied by a due proportion of phosphoric acid, since neither potash nor phosphoric acid will have as good effect applied alone as in combination. With nearly all the cereal grains it will be found that phosphoric acid is the controlling factor in any mixture. But in clover the proportion of potash is considerably larger than that of phosphoric acid. Then in devising a fer- tilizer for the wheat crop on which we propose to sow clover it will be wise to regard the needs of the clover for potash, and supply it; for we may rest assured that the soil will hold on to it for the clover, even if the wheat does not need it. A practice has grown up in sections North, where the crop can be grown early in Summer, of placing boards on each side of the single rows, so that the celery is crowded for light and runs up tall and tender. This method is used only for early celery, since the boards would not be a sufficient protec- tion against the cold late in the season. The self blanching varieties are used for this crop more than others, and, in fact, the self blanching sorts are only fit for such treatment, as they are far inferior in quality to those. kinds that are commonly grown and blanched by earthing. ‘They make beautiful,- white stalks, but the quality is very inferior. While in the northern parts of the country celery is largely grown on black, peaty, marsh land, where it attains a fine size and appearance, in quality this celery is far inferior to that grown on a moist and fertile clay soil; being more pithy and hollow stalked. The finest quality of celery is that grown from a good strain of seed on a clay soil of good fertility, amd irrigated, as needed, in dry weather. While it may not be so large and showy as the product of the marshes, it is far superior in solidity and crispness, qual- ities essential to a fine celery. In regard to the fertilizing of the celery crop the following from Bulle- tin No. 182 of the Cornell University_Experiment Station will be of interest. CELERY—217 The land on which the experiments were made was flat, muck land, or half wild meadow, broken up that year. It had never grown celery nor had it ever received any fertilizers. The results of a series of various applications is summarized as follows: “All the records show that wood ashes gave the best results, although a combination of nitrate of soda, South Carolina rock and sulphate of potash promises to do well. Muriate of potash excelled the sul- phate. Nitrate of soda, alone, gave poor results. The check plats, without fertilizers, were not worth the growing.” FERTILIZERS FOR THE CELERY CROP. We have said that where the celery crop follows a heavily fertilized early crop on a good moist soil, there is little need for further manuring. But cel- ery is especially fond of potassic manures and nitrogen. Hence if there has been any deficiency in the early manuring, there should be some commercial fertilizer applied. We would not use stable manure on the celery crop direct, because of its drying tendency in heavy applications. The following, used at rate of 1,000 pounds per acre, will be found well suited to the crop: Acid phosphate or dissolyed bone black, 800 pounds; fish scrap or tankage, 800 pounds; muriate of potash, 400 pounds to make a ton. In all these formulas we give the component parts of a ton of 2,000 pounds. But of course the same proportions can be used in smaller quantities. The fertilizer should he applied at least a week before setting the plants, and should be well mixed with the soil by harrowing, as otherwise the caustic effects of the potash may injure the roots of the plants. Put the fertilizer broadcast, for either in rows or beds the plants will finally get it. The same fertilization will answer for the thick planting adopted with the self blanching sorts. VARIETIES OF CELERY. Formerly the giant sorts were commonly planted, and they are preferred still, in the South, to some extent. But by far the finest quality is found’ in the dwarf and_ half-dwarf varieties. Golden Heart or Golden Dwarf is the sort most generally popular. White Plume and Golden Self Blanching are the kinds’ generally used for self blanching. In the South the Giant Pascal is the most popular sort, and the Sandringham is also found to be excellent. The Boston growers use the dwarf sort known as the Boston Market, a very dwarf sort that makes a great many tender and crisp offshoots, and is a very good variety for bed culture. Pink celeries are sometimes praised as better than white, but the market does not care for them. CHAPTER XXX. CUCUMBERS. Cucumbers are grown by the Southern market gardeners in great quan- tities for early shipment to the Northern markets. They are also very large- ly grown in the North by those who are not regular market gardeners, for the supply of the pickle factories late in the summer. Then there are large num- bers grown near all the large cities in hot houses in winter; of this culture we will have more to say in the proper place. It was formerly thought essen- tial for all the cucurbitaceous plants, such as cucumbers, melons and squashes, that the hills should be prepared with a libers] deposit of stable manure or compost in the hills, and there is no doubt that where facilities exist for this compost it is still an excellent plan. But, in growing the early cucumber crop on a large scale and at a distance from a supply of stable manure, it has been found necessary to use artificial fertilizers. As the value of the crop de- pends on its earliness the artificial inapures are better for forcing this early growth. A mellow, sandy loam, neither wet nor too dry, is the best for the early crop. The soil should be plowed very early in the season, shallowly, to de- stroy the hardy weeds that may be appearing, or the crop may be made to follow the crop of early cabbages which have been heavily fertilized, by plant- ing hills in alternate rows. But a better crop can be grown by preparing the iand especially for the cucumbers. In preparing the land for planting it is plowed in beds six feet wide, and a subsoil plow is run deeply in each dead furrow. The fertilizer is then applied in the dead furrows heavily, and a furrow is turned from each side so as to make a ridge (or list) over the ma- nure. We then flatten this list with a hand roller, and sow the seeds while the land is fresh. The first cultivation is to plow the land to the rows so that the rows of plants will stand on top the lands and the new dead furrows are in the middles. This is done after a good stand has been secured, and the earth is drawn to the plants, so as to have the roots deep in the moist soil. The plants should be thinned to about one foot apart in the row. Subsequent cultivation is with the small tooth cultivator till the vines are running so as (218) CucuUMBERS—219 to stop further cultivation. The crop is always cut with a small piece of the stem attached, and the cucumbers are shipped in slatted crates. One thous- and bushels per acre of marketable cucumbers is a common crop with the gardeners of the South Atlantic coast, and the same method of culture is equally well adapted to the crop in any section, but the planting season must follow the disappearance of frost from South northward, as the cucumber is a tender plant and must not be planted till the soil is warmed. - VARIETIES OF CUCUMBERS. The standard variety with the market gardener is the White Spine. Every enterprising seedsman has his special strain of this variety, and it has never been superseded as a variety for field culture, and is also grown to a large extent under glass. For the late crop, for pickles, in the North, some of the strains akin to the Long Green are used. The Perfected Jersey Pickle is one of the best of these. There are some small varieties that are earlier than the White Spine, but they are of no value to the truck farmer and only of use in the private garden for their earliness. The little prickly Gherkin is also grown to some extent for pickling. The late crop of pick- ling cucumbers belongs almost exclusively to the Northern gardener and farmer, since the late crop is rarely a success in the South, owing to the drought and the borers. But in low, moist, bottom land they may be well grown even in the South. These pickles are planted in mid-summer, and commonly occupy land from which an early crop that was heavily manured has been removed, and no special manuring is given on such land. FERTILIZERS FOR THE CUCUMBER CROP. As this crop is fertilized, as noted, entirely in the furrow, the fertilizer need not be used heavier than 500 pounds per acre. Just as the plants ap- pear through the ground it has been our practice to keep them dusted with fine bone meal, to keep off the bugs. This also helps the growth of the plants. For a fertilizer mix acid phosphate, 900 pounds; fish scrap or tank- age, 700 pounds; nitrate of soda, 200 pounds; muriate of potash, 200 pounds. In localities where the phosphate made from bone black, or the Thomas slag phosphate, can be had more cheaply than the acid phosphate made from the dissolved rock, they can be used in place of acid phosphate in any of the formulas, and fish scrap, a good article of tankage, or dried blood, may be used indiscriminately without any serious change in the nitrogen con- tent. Where cotton seed meal is used as a source of nitrogen it must be used in larger quantity. The tables appended in the back part of this book will 220—CROoP GROWING AND Crop FEEDING show just what percentages of nitrogen and other ingredients are found in all of these things, and we will hereafter try to show how certain percentages may be made in the mixtures. STARTING CUCUMBERS UNDER GLASS TO ADVANCE THEM. In many works on gardening the advice is given to sow the seeds on in- verted sods, place them under glass and water them; and then transplant to the field, sod and all. This may be made to answer where blue grass sods are plentiful, but it is at best a clumsy and inconvenienteplan, and in the South, where sod is mainly Bermuda grass, it is totally impracticable. The market gardener should always be provided with an abundance of frames and sashes, and with flower pots of various sizes. These pots can now be had by the thousand so cheaply it will not pay anyone to go to the trouble of cutting sods for starting his plants. The method we have used successfully to get an extra early start with cucumbers and muskmelons is to use pots of the four inch size. These are filled with the regular potting compost used in the culture of greenhouse plants, and the soil well settled in them to within an inch of the top. They are then packed in cold frames evenly and level, and seeds are scattered on the pots, three or four to a pot, and the same rich compost is sifted over the whole. This is done after hard frosts are over, and the cover of the glass sash will be sufficient protection. But some means should be at hand to cover the glass with a mat should an unexpectedly hard frost occur. The pots must not be allowed to suffer for water, and the plants should be thinned to two in a pot as the rough leaves appear. When the weather is settled and the ground warm they are easily knocked out of the pots, with balls entire, and set in the rows. We always set them a little deeper than they were in the pots and have had very great success in getting a perfect stand. We see at times all sorts of curious contrivances advised for the starting of plants, such as hollowing out turnips, cutting sods, and melting the tops and bottoms from tin cans. But the true gardener knows that none of these things are so good or so cheap as the regular flower pot. The four-inch size can now be had for about one cent each, and with care will last for many years, and are far cheaper and better than any of the troublesome substitutes advised. A gardener, like a farmer, should be a systematic and business-like man, and never a potterer or a piddler, spending more labor over a substitute than a real garden appliance would cost. Tin cans and hollowed turnips are on a par with the plant cloth which some gardeners think as good as glass on their frames. Good gardening calls for the best garden appliances, just as good farming calls for the best tools. CHAPTER XXXII. EGG PLANTS. This crop is grown to some extent in the far South, in Florida, as a crop to ship North, but is grown very little in the Middle South; and again in the Northern market gardens it is rather largely grown. The gardener from the North, coming South, is surprised to find that in private gardens here it is rarely seen, and in the markets of the Southern cities is rarely called for. This is largely owing to the fact that, like the tomato, it is a more difficult crop to grow in the South than in the North, owing to the ravages ‘of the blight, which is worse, if possible, on the egg plant than on the tomato. The egg plant is a very tender plant, and the methods used for the production of the tomato will hardly do for it, since any effort to harden off the plants in frames is sure to result in a stunted growth and comparative failure. Our practice is to sow the seeds about the last of February in a warm greenhouse or a hotbed under glass, and as soon as large enough to handle transplant to pots two and a half inches in size. As soon as the roots show around the balls in these pots they are transferred to four-inch pots and still kept in the house. Not until the ground is well warmed and vegetation active outside should they be transferred to the open ground. We have then found that no matter how much fertilizer may have been used on the land that a top dress- ing of stable manure as a mulch to the surface is always a great advantage, particularly if the land is a dry clay and inclined to bake. We set the plants three feet apart each way, and aim never to allow a crust to form on the sur- face. The plants need as close watching from the Colorado beetle as the potato plant. In fact, we think they are fonder of the egg plants than of the potatoes. Rather than use poison we prefer to pick the mature beetles and crush the orange colored masses of eggs on the under side of the leaves. If the crop is very early it will be a profitable one, but later the price goes too low for distant shipment. Many years ago in Northern Maryland, having an abundance of vacant frames after our tomatoes had been transplanted to the field, we set 600 sashes with two egg plants each, and kept the glass over them (221) 222—Crop GROWING AND Crop FEEDING at night till June. In the rich manured soil of the frames they grew astonishingly, and were ready for market before the Charleston crop was in, and brought, for the first, $4 per peach basket; the largest price we ever got for egg plants. The gardener in the Upper South who is wise enough to in- vest largely in glass, can always compete on favorable terms with those south of him in the open ground. VARIETIES OF EGG PLANTS. The standard variety of egg plant in all the market gardens North and South is that generally known as the New York Improved. There are many strains of this. The Black Pekin is earlier, smaller and of fine quality. The Early Long Purple is the earliest of the older sorts, but not grown for market, as the market demands round sorts. We have grown this season, for the first time, a variety from Italy which seems to be a cross between the Black Pekin and Early Long Purple. It is of the same shape as the Long Purple, with the purplish foliage of the Black Pekin. It is very early and wonder- fully productive, and so far has resisted the bight which destroyed our New York Improved to a plant in the adjoining rows. Its small size and odd shape will be against it as a market sort, but in quality it is ahead of any- thing we have ever tried in the egg plant family. It is common to see as many as ten fruits on a plant ready to cut and many more forming. The fruits are inclined to grow crooked like a crookneck squash. What the name of this is we do not know, as the seed was sent us by number for trial from the division of the Agricultural Department for the introduction of new plants. We believe, at least for the family garden in the South it is a valuable acquisition. FERTILIZATION. It is useless to try to grow egg plants unless the soil is rich and heavily fertilized. They can be set on the land where the crop of early peas has been gathered and the vines plowed under. But as the pea crop does not need the heavy fertilization of other garden crops there should be an application of not less than 1,000 pounds per acre of the mixture advised for the cucumber crop, and, if possible, in the South at least, a further mulching of stable manure on the surface after or just before the plants are set. CHAPTER XXXII. LETTUCE. In all parts of the country, North and South, in the open ground and under glass, there is no crop that engages the attention of the skilled gardener more than the lettuce crop. This, of course, refers to the winter culture of the crop in frames in the South and in heated houses in the North. The outdoor crop, while an important one, is of far less profit and importance than that grown under protection. In Florida the crop is grown, all through’ the cooler part of the year, outside, and as we advance up the coast we find lettuce engaging the attention of the winter gardener in frames, protected either by awnings of cotton cloth rolled up and down on rafters, or in the reg- ular cold frames with glass sashes. In the North acre after acre of steam and hot water heated houses is devoted to the winter production of the lettuce crop. And with all this production, there has never been a time when good head lettuce has failed to bring a good price during the cold months from November to April. The gardeners along the South Atlantic seaboard use cotton cloth almost exclusively for the production of winter and early spring lettuce. We have long tried to show them that this is a mistake, but the first cost of the glass is so heavy that they hesitate to undertake a large area in glass. The cloth covered frames cost $500 per acre, and the cloth has to be renewed every sec- ond year. If a heavy snow comes, the gardener with cloth covered frames is in a bad way, for the snow will slide on his bagging cloth and press down on the plants, and hence must be removed. As cold always follows a snowfall. he then has not sufficient protection from the cloth and his plants get dam- aged. With the glass sashes a snowfall is a protection against the cold that follows, as it can be left on the frames. Experienced growers have admitted to me that they could grow a third more and better lettuce in glass frames, but they hesitate to make the expenditure of $3,000 per acre for the glass when the crop is worth that much per acre annually under cloth, and would (223) 224—CroP GROWING AND Crop FEEDING be worth more under glass. In fact, here in the Upper South, we can pro- duce in a simple cold frame, with mats for protection in unusual cold, as good lettuce in the dead of winter as the Northern gardener can get in his expen- sively constructed and heated greenhouse. he frames used in the South for the production of winter lettuce are made 12 feet wide and have a ridge pole running the length of frame, one-third the width, from the north side, so as to give a long slope to the south and a short one to the north. The canvas is sometimes on rollers, like awnings, and sometimes is merely stretched over the pole, and held in place by eyelets on hooks in the sides of the frame. Aside from the imperfect protection of the cloth there is the further disadvantage | that the whole must be taken off to give the plants full sunlight, and in cold weather this cannot be done, and the plants get drawn in the partial shade; while under glass, when the weather is too cold to uncover, they are exposed to the full sunshine and grow sturdy and short stemmed and head far better. The frames for growing lettuce under glass are made about six feet wide, so as to admit a 3x6 foot sash. The back of the frame towards the north is made 18 inches high and the front 12 inches so as to give a slope to the sun. Some make the frames wider and have a ridge pole and a short wooden span to the north, but this makes the frames unhandy, and the lettuce under the wooden slopes is poor. The chief points to be observed in growing frame lettuce after the preparation of the soil of which we will speak, are to keep it as near 40 degrees Fahrenheit at night as possible and to give air in all sunny weather to prevent too high a temperature, which would result in a flabby growth and poor crop. At all times when the sun shines, and that is nearly all the time in the South, and the temperature is above 25 above zero, we admit some air, and when there is no frost we fully expose the plants, even at night. CULTURE OF FRAME LETTUCE IN THE SOUTH. The best soil for the lettuce crop is a sandy loam. This inside the frames should have a heavy coat of black leaf mold from the forestscreened to remove all coarse roots and trash, and spread three inches deep in the frames. The frame is then ready for the application of the fertilizer. As this should be used without stint and should have, on such a soil, a large percentage of potash, it should be applied at the rate of a ton and a half to two tons per acre of area enclosed, several weeks before setting the plants, so that the caustic effect of the potash may disappear. On a clay-loam soil the fertilization is better with a heavy application of well rotted stable manure and a lighter dressing of the phosphatic and potassic fertilizers. The wide awake gar- LEtTTucE—225 dener in the South will always plan for two crops during the winter, by re- planting as rapidly as the early (or Christmas) crop is out. For the first crop, to come off from the first of December to Christmas, seed of the Tennis Ball or Boston Market should be sown the last week in August, and will be ready for the frames a month later. These varieties can be planted six inches apart when the frame is occupied by lettuce alone, but when a crop of cauli- flower is also grown in the frames they will occupy the place of ten lettuce plants and the sash will then hold 40 lettuce. | Where the frames are to be used for a succession crop of lettuce it will not be practicable to grow the cauliflower and they must have room by themselves. But where practicable it is not best to replant the same frame in lettuce, as the second crop is apt to be more or less diseased. In fact, so much trouble has been had from this, that some of the largest growers now do not try to have an early winter crop, but plant entirely for the late winter and spring market, when the price is usually highest. But where practicable it will be found best to have extra frames for second crop of lettuce, and to leave cauliflower after the Christmas lettuce is cut, with only protection of mats or cloth in cold snaps, and to re- move the glass to the extra frames for the later lettuce. These frames being prepared at the same time as the first will have gotten well sweetened by frost, and will make the finest of crops. Seed for the late winter and spring crop is sown late in September, in a sheltered spot, and a little later it is well to mulch the plants lightly with strawy manure as a protection, though they will usually winter fairly well here, unprotected. At the same time it is well to sow some seed of the varieties that are not grown under protection, so as to have them to set later in the field along between the rows of early cabbage, to be cut in the spring before the cabbages need all the room. For this pur- pose there is no better lettuce than the Improved Hanson. For the late win- ter and spring crop in the frames we sow the Big Boston and the California Cream Butter lettuce. The Big Boston is commonly used for both crops by our market gardeners here, but for the Christmas crop we prefer the Bos- ton Market, as it heads compactly at an earlier -period. The growing of lettuce under glass in the North differs from that in the South only in the place where the plants are set. There the crop is grown in wide, flat-roofed greenhouses, in which a night temperature of 40 to 45 degrees is maintained, and free ventilation given in day time. The plants are set in well prepared compost on the benches of the houses, and require far more care and attention than the Southern frame crop, as the plants are more liable to disease and the attacks of aphides and other insects; but the crop is so generally profitable and the quality so fine that the area annually devoted to lettuce is rapidly increasing. Near Boston, where, in winter, the 226—Crop GROWING AND Crov FEEDING growers are troubled with long, sunless spells, it has been found profitable to string are lights over the houses for forcing the crop. This is a refinement in horticulture that few will imitate. The culture of frame lettuce will be more fully treated in chapter on cold frames. LETTUCE IN THE OPEN GROUND. This is the crop that most farmers are more interested in than the forced crop. Anywhere from Virginia south lettuce plants can be safely wintered over outside with slight protection of manure in the northward section. In the North, however, it is best to winter the plants over in frames, as cabbage plants are there carried over. The market gardener, with his costly and fertile land will get the early outdoor crop from plants set between the cab- bages, and will have it out of the way before the cabbages need all the room. Otherwise the plants are set as soon as the ground can be worked in the spring, in well enriched soil, and make a good crop to be followed by some tender plants, which cannot be set till the ground is warm. THE MANURIAL REQUIREMENTS OF LETTUCE. Lettuce, like most foliage crops, needs an abundant supply of nitrogen, and also in the soil it prefers, a light, sandy loam, a large percentage of pot- ash with a fair proportion of phosphoric acid; though this is of less import- ance than the first two. Occupying the soil during the winter months, when there is not a great activity among nitrifying organisms, it is essential that the fertilizer be presented not only in lavish amount, but in a perfectly solu- ble form. Hence for frame lettuce we would make a mixture of acid phos- phate, 900 pounds; dried blood or fish scrap, 600 pounds; nitrate of soda, 100 pounds, and muriate of potash, 400 pounds. The large percentage of potash renders it necessary, as we have said, that the fertilizer be applied some time before setting the plants, usually one month. But the nitrate of soda should he reserved and not mixed with the other ingredients, but scattered between the rows after the plants begin to grow. The first frame crop set in the South in October, will need no protection till the later part of its growth, in late November and December, but the protection should be at hand for the first cold snap. VARIETIES OF LETTUCE. The varieties used by the growers of winter lettuce are few. The mar- kets of the Eastern States demand a well headed lettuce, while in the West the curled and loose headed sorts are popular. For the fall crop we prefer LETTUCE—227 the Boston Market, since it can be set twice as thick as the Big Boston, but - for the late winter and spring crop the Boston Market and California Cream Butter lettuce are superior, though they require a foot distance to the six or eight inches of the first named. For the open ground crop to be set in the fall in the south, or in frames for wintering over in the North, there is no lettuce equal to the’ Improved Hanson. It is the largest and most solid heading of all lettuces, and can easily be grown to weigh ten pounds or more per head. For sowing in spring the New York and the Boston Fringed lettuce stand the heat better than others, but any lettuce will soon run to seed in warm weather, and late spring and summer lettuce is milky, bitter and of little value as compared with that grown in cool weather. There are long lists of varieties offered in the seed catalogues, but many are of little value to the market gardener. The best of the loose heading sorts is the Grand Rapids, which is popular in the West, but is little grown in the East. It makes very large bunches and is of fine quality, especially for decorative purposes. To persons of discriminating taste there is no doubt that the Grand Rapids lettuce is far superior in quality to the heading or cabbage sorts, and if once a community is educated to the using of the curled sorts they will sell in preference to’ the cabbage varieties. But at present it will hardly pay the gardener in the eastern part of the country to try to educate people into taking what they are not accustomed to. If the crop is grown for any of the markets West, the Grand Rapids is the variety to grow, and perhaps after a while the Eastern cities may find out its superiority. In the mean- time, if you are growing lettuce for home use, we would advise the curled sorts as of greatly superior quality and beauty to the cabbage lettuces. CHAPTER XXXTII. MELONS. MUSKMELONS. What has heretofore been said in regard to the manurial requirements of the cucumber will apply equally well to the muskmelon crop. This crop prefers a soil of much heavier texture than the watermelon, and delights more in moist conditions in the soil. We plant muskmelons in hills six feet apart, and make wide holes where each hill is to be, using to fill these holes a com- post made of black earth from the woods and stable manure in equal parts, piled some months before in a flat heap and frequently turned until com- pletely well mixed and homogeneous. Just before planting we scatter a small handful of any good complete fertilizer having a high percentage of nitrogen in it over this, and cover with soil before planting the seed. We use an abundance of seed, as it is an important matter to get a complete stand at once. As soon as the plants can be seen breaking through the soil we dust them over with fine raw bone dust, to keep off the striped beetles that prey upon them; the bone dust is also a good fertilizer. When the rough leaves develop and danger from the bugs is past, we thin to two good plants in a hill, and cultivate flat and shallow with a cultivator till the vines get in the way, after which weeds are pulled from among them by hand. Some large market gardeners adopt a different plan and use commercial fertilizers entire- ly. They plant the melons between the rows of the early peas, running a fur- row down the middles, and applying a good dressing of high grade nitroge- nous fertilizer all along the furrow. Two furrows are lapped on the first one, making a slight ridge, which is flattened down and a shallow furrow, in which the seeds are scattered, is made on the flattened ridge. As they de- velop they are thinned to stand about two feet apart in the rows, and when the peas are off the vines are turned under and the melons cultivated. They are also planted between the rows of early snap beans and treated in a similar way. The variety mainly grown by the Southern truck growers is the small early sort known as Jenny Lind. This is early and of a size easily packed in crates for shipment, and is more largely grown here than any other. Of (228) MELONS—229 late years there has been a great deal of interest in a variety known as the Rocky Ford, from the locality in Colorado where it has been largely produced and shipped East. The high quality of the Rocky Ford melons caused them to bring fancy prices in the East, and many have tried the variety here. But it has been found that the Rock Ford is the same variety that has been long grown under the name of Netted Gem, and that it seems to be the soil and climate at Rocky Ford that has given them their fine quality. Why the difference should exist between the Netted Gem in one section or another re- mains to be determined, and several of the Experiment Stations are entering into the investigation of the effect of soil and climate on this variety. In Europe there are a number of varieties of winter muskmelons grown. ‘These mature late in the season, can be put away to ripen indoors and will keep till Christmas. For some reason these melons have never become popular in this country, but experiments are now being made with them, and it may be that there will be found some that suit our climate. For a home mixture for muskmelons we would suggest the following: Acid phosphate, 900 pounds; dried blood, 600 pounds; nitrate of soda, 100 pounds, and sulphate of potash, 400 pounds, to make a ton. Where the con- centrated fertilizer is used exclusively we would use 500 pounds per acre. As a dressing on hills of compost half this quantity will be sufficient. At the last working of the crop it is a good practice to sow cow peas among the rows, as they quickly grow up and make some shade from the sun, and after the crop is off there will be a field of peas to turn into forage. WATERMELONS. The watermelon is very similar in its manurial requirements to the muskmelon, but if grown in well manured or fertilized hills it can be profit- ably grown on poor, sandy land that would not make a good crop of musk- melons. ‘The same making of a rich bed of compost in the hills is practiced with the watermelon, but the hills are much further apart than those of the muskmelon. Ten by twelve feet is a good average distance to plant, and the sowing of peas between the rows is of more importance here than with the muskmelon, as the watermelon likes to hide in the shade and is damaged by the hot sun. The crop, like the muskmelon crop, can be grown with com- mercial fertilizers alone. One of the best watermelon crops we ever grew was on a sandy piece of bottom land where the soil was deep and moisture always in reach. This land was plowed in twelve foot lands early in the spring and the dead furrows well plowed out. A heavy dressing of the fer- tilizer given above was then scattered along the dead furrows. ‘Two furrows 230—Crop GROWING AND Crop FEEDING were lapped on this, making a sharp ridge in the dead furrow. This ridge was flattened slightly and a shallow furrow made on it in which the seeds were sown. The crest of this bed was then quite below the level of the top of the intervening lands. As the seeds appeared to germinate the bone dust was ap- plied and when washed off by rain, renewed. As the plants developed they were thinned to three feet apart and but one plant left in a place. The first working was to throw furrows to the row from each side, and this process was continued until, when the cultivation was done, the rows of plants stood on top the lands and the dead furrows were between them. In this way the roots were gotten down into the moist lower soil. and flourished as I have never seen them since; and the crop was as-fine as ever seen. About 700 pounds per acre of the fertilizer was used. This amount could not have safely been applied to sandy land at a greater elevation or on a dry hill, but on this soil, where moisture was always in reach, the fertilizer was completely dissolved and used by the crop. There are so many varieties of watermelons grown that it is hard to recommend the best. For growing for market and for long shipping, there is no variety equal to the round Kolb Gem. ‘This is of fair quality and good appearance when cut, and has a tough rind that bears handling. But for home use and a near market it is far inferior to many others. Like a great many other things, the variety best adapted to shipping purposes is not of the best quality. In our experience we have found no watermelon that can equal in quality the McIver Sugar melon. It grows to a large size, has a thin rind and beautiful scarlet flesh, which never cracks in wet weather, as most other varieties are apt to do, and in quality it leaves nothing to be desired. Next to the McIver we would place the Jones, a very large, dark green melon of a round shape. It is a very productive sort and will make melons from 50 to 70 pounds weight, or even more. With these varieties we do not think either the market grower or the home gar- dener need look further, for they combine all that is needed in a watermelon. CHAPTER XXXIV. ONIONS. There is hardly any culinary vegetable more largely grown North and South than the onion, and there is no crop to the perfection of which the commercial fertilizers are better fitted, be- cause of the tendency of stable manure to introduce weed seeds, and there is no crop that must be kept more clear of weeds than the onion. “Clean as an onion bed,” has grown into a maxim in culture. Our market gardeners grow onions very largely for bunching while green in the early spring, the main crop of onions ripened and sold in barrels are grown on lands especially adapted to the crop, and by farmers rather than gardeners. The methods for producing the crop are as various as the purposes for which it is grown. In Bermuda, and to some extent in Florida, the so-called Bermuda onion is grown by sowing the seed in the fall for the winter crop. Onions prefer a cool climate and a moist soil, and when grown in the South, they must be given the most favorable season in which to grow. Anywhere south of Virginia it would be perfectly feasible to sow onion seed in September for the early green crop in the spring. But we have found that our September weather is so uniformly dry that at ‘that time getting a stand of onions from seed is very uncertain. Hence for this green crop we are compelled to resort to the use of sets. GROWING THE SETS. We use seed of the Queen onion for the growing Gs sets, since they are only used in the production of the green bunching crop, and we want a quick growing onion rather than a large one. Growers in the South, and even in the Middle States, have gotten so much in the habit of grow- ing their onions entirely from sets, that growers in many section in the Northern States, make the growing of sets an import- S (281) 232—Crop GROWING AND Crop FEEDING ant crop, and we find on the market sets of all kinds, white, yellow and red. But the Southern grower is fast finding that he does not need sets, except for the production of the spring bunching crop, and for this purpose he wants a white set. After a number of experiments we have found that the Queen gives us the best results for this purpose. Since onion sets should be of small size, the thicker the seeds are sown the better. It is our practice here to sow seeds for sets the first of April, in rows, and so thickly that it will take about 60 pounds to sow an acre. Sown in this way they crowd each other and the product is a mass of bulbs about the size of small marbles, ripe here in early July. These are gathered and cured with the tops left on, for we find that they soon start to sprout when the tops are removed. Hence the tops are not taken off till we are ready to use or sell the sets. These sets are planted in September, as it is important that they get well started and a young bulb under way before coid weatne:. EARLY GREEN ONIONS IN THE SOUTH. We have long since found that while we can grow as fine onions from the black seed in the South the first season as can be grown elsewhere, and that for the purpose of growing a ripened crop the sets are practically worthless, we are compelled by the character of our autumn weather to use the sets for the early crop, which goes North late in winter and early in spring. The onion is one of the few crops which are better fertilized in the hill than broad- cast, since the roots have a more limited range and are better nourished by having the fertilizer placed right below them. Therefore for this early crop we mark out furrows, early in September, two feet apart. In these furrows we scatter the fertilizer and then bed on the first furrow with two others, one from each side, making a ridge over the fertilizer. This we flatten with a hand roller, and mark out a small furrow on the bed in which the sets are placed so that when the soil is pulled away in late winter the bulbs will be on the surface. We set them rather deep in the bed as a protection till hard frosts are over. As the crop is pulled and bunched when half grown, the sets can be placed two inches apart in the rows. We have said that for this early crop we use sets of the Queen onion. We have succeeded very well with the Bermuda onion in the same way, and the white potato onion, or Multiplier, is being largely used for fall planting, as it stands the winter better than most other sorts and makes a short top. The fertilizer requirements of onions are mainly for nitrogen and potash. Analysis shows a very small percentage of phosphoric acid in the onion when compared with the other constituents. OnIONS—233 Another way to produce the early onion crop in the South is to sow the seed rather thickly in August on land that is naturally mellow and moist, and which is heavily fertilized with a fertilizer mixture containing a large percentage of potash, the formula for which is given under the proper head. This crop should be well cultivated through the fall, and it will be found that if the fall weather is favorable some of the onions will grow to quite a size, and these it is best to thin out and use for pickling onions. Hence the reason for rather thick sowing. As cold weather comes on the earth is drawn to each side the rows as a winter protection and to be removed as the weather warms in early March, to give the onions a chance to bulb on the surface. In cold latitudes the cold frame can be utilized for the fall onion crop. THE GENERAL CROP OF ONIONS. When it comes to the growing of ripe onions for keeping and shipping there is no need for sets either North or South. It is simply a matter of earlier sowing and earlier ripening in the South. The onion prefers a moist soil abounding in humus, so that it can have uniformity of moisture during its growth. Hence reclaimed swamp lands are well suited to the crop and in many sections such reclaimed areas are being very largely devoted to the onion crop. At the same time, such soils are apt to be particularly deficient in the potash so essential to a good onion crop, and while the soil is apparent- ly very rich, the onion crop would fail to bulb well. It will not do to assume that any soil is rich enough to grow onions without any fertilizer. With a crop that varies so largely in quantity all the way from a few bushels per acre to over a thousand bushels, it is evident that the presence of a lavish supply of plant food in a readily available form is essential to the produc- tion of onions. 16 159.2 bus. 16 182.1 22.9 bus. The Long Island formula gave better results with each quantity of fertil- izer and produced an average of nearly 23 bushels per acre more than did 250—Crop GROWING AND Cror FEEDING the formula based on the composition of the tubers. The difference between the two fertilizers was strikingly shown by the appearance of the vines, for those upon the Long Island formula plats were one-fourth larger than those receiving the other formula, and in at least one instance the vines were of a darker green. The two fertilizers differed in the proportions of two ingredi- ents only, the Station formula being richer in nitrogen and poorer in phos- phorie acid than the Long Island formula, potash being the same in each. The variation in effect of the two combinations seemed greatest where the smaller quantities were applied, which may indicate either that the Station formula did not, in small quantities, furnish enough phosphoric acid, or that in large amount it contained an undesirable quantity of the nitrogen compounds. In either case, if future experiments substantiate the results of this trial, the claim that the composition of a crop should be the guide in mixing special fertilizers will be discredited. As the best form of potash the bulletin says that it has been thought, and has been supported by some experiments, that the liberal use of the muriate of potash tends to lower the percentage of starch and dry matter in the potato, therefore chemical analyses were made of tubers from each plat and’ comparisons were made of those re- ceiving potash in the two forms of sulphate and muriate, in hope that light might be thrown on that question. Taking the average of 16 plats for each manner of treatment, it was found that where sulphate of potash had been used the potatoes produced more of both dry matter and starch than where muriate had been applied. But the significance of these results was utterly nullified by the fact that the tubers from the unfertilized plat adjacent to those differently fertilized differed in the same way, and to almost exactly the same extent, seeming to show that it was a natural difference in the soil of the plats rather than the kind of fertilizer used. The muriate in our own experience has always given the largest yield, and so far as table tests can go of fully as good quality as those grown with the sulphate, which is the more costly form. This fact is borne out by the results at the Cornell University Experi- ment Station, where an application of 200 pounds of muriate of potash and 300 pounds of acid phosphate made 318.2 bushels per acre, and the same amount of fertilizer with the potash in the form of a sulphate made 310.5 bushels per acre. On two other plats the difference was still greater, for the plat on which the same amount of muriate of potash was used made 360.6 bushels per acre while the plat on which the sulphate was used made but 333.5 bushels. Potatoes that were cultivated thirteen times made a smaller crop than those cultivated nine times, and it was evident that nine cultiva- tions will give the better crop in an average season. Still, as the bulletin IgisH PoraTroEs—251 well states, the effects of good culture are very plain, for in spite of adverse conditions the crop was an excellent one. The average yield of potatoes per acre in the State of New York the same year was only from 50 to 65 bushels per acre, while the average on the Station grounds was over 300 bushels per acre, on soil not naturally more fertile than the average, and, in fact, showing by analysis a lower fertility than the average. In a subse- quent bulletin from the same Station it was found that six or seven cultiva- tions gave the best results, and that success with the potato crop depends largely on the preparation given the soil before the potatoes are planted. Plowing should be deep, and at the time of planting the soil should be mellow and loose, the crop planted early and deep and the cultivation frequent and level. Harrowing before the potatoes came up gave marked results. The Rhode Island Eperiment Station has done a great deal of work in the investigation of the effects of lime on soils. In regard to the growing of potatoes free from scab, the statement is made that on land in an acid con- dition and containing no lime, the potatoes may be grown practically free from scab, if only commercial fertilizers are used; that a gain in the crop may be made from an application of lime on such soils, but the prevalence of the scab is increased thereby. Wood ashes will also increase the amount of scabby potatoes. An application of the chloride of lime entirely prevented the scab, but injured the crop of potatoes. The sulphate of lime, commonly known as land plaster, is the only form of lime that was found not to injure the growth of the crop and at the same time did not favor the increase of the scab. Barnyard manure, owing to its alkalinity or the production of car- bonates from it, has probably in and of itself increased the scab. Upon an acid soil, practical immunity from scab has been secured upon three successive crops by the use of fertilizers such as the ordinary commercial fertilizers, even when scabby tubers were used as seed and were not treated for the scab. On such soils the potatoes can be profitably produced by the use of commer- cial fertilizers. At the Ohio Station it is stated that superphosphate has increased the potato crop to a profitable extent, the cost of a bushel increase being but five to six cents. There was not found much difference in the efficiency of super- phosphate from the dissolved rock and from bone black, but slag phosphate gave lower results than the other forms. Wheat bran was a better fertilizer than linseed meal. Nitrate of soda and muriate of potash, when used singly, have not given much increase. Superphosphate, nitrate of soda and muriate of potash in combination have given better results than either alone, and the crop increase has been nearly in proportion to the quantity used up to 1,100 pounds per acre. 252—Crop GROWING AND Crop FEEDING At the Maryland Station it was found that a complete fertilizer in which nitrate of soda and an organic form of nitrogen was used in conneetion with acid phosphate and sulphate of potash, gave the best results in the crop, mak- ing several bushels more than the same formula with muriate of potash used in place of the sulphate. At the Pennsylvania Station it was found that the use of nitrogen re- sulted in a profit of from $2.17 to $9.56 per acre, according to the combina- tion in which it was used. The use of phosphoric acid resulted in a gain of $7.72 per acre. The use of potash resulted in a gain of $17.39 per acre. The -use of phosphoric acid and potash together produced a gain of $52.02 per acre, while a complete fertilizer containing nitrogen, phosphoric acid and potash made a gain of $56.88 per acre. Nitrogen alone made a gain of $2.17 per acre, showing a difference in the effect of an incomplete and complete fertilizer of $54.71 per acre. The conclusions arrived at were that on that soil potatoes especially needed potash, and to a somewhat less degree, phos- phorie acid. The effect of nitrogen being shown to be small, it would seem that instead of purchasing costly artificial supplies of nitrogen, if potatoes are to be grown extensively, it would be better policy to secure the needed sup- ply of nitrogen from the air by the cultivation of leguminous crops, either used as green manure or fed to animals, and to confine the purchase of arti- ficial fertilizers to phosphate and potash. It seems altogether probable that such a method of treatment would suffice to keep the supply of nitrogen in the soil up to a point at which purchased mineral fertilizers would yield their best returns. A very important point is the using of phosphoric acid and potash together, for in one experiment, while the phosphoric acid alone gave a gain of $7.72 per acre and potash alone $17.39 per acre, when the two were combined they gave a profit of $51.02 per acre. In some other soils experi- ment has shown that while potash was as important as in these the next im- portant element was nitrogen, and this is usually the case in the early crop of potatoes grown in the South in the early spring. The Pennsylvania bulletin further states that it may be interesting to compare the amounts of nitrogen, phosphoric acid and potash applied in these experiments with those contained in the so-called “potato fertilizers” so large- ly offered by various fertilizer firms, the average of 47 samples of such fertil- izers analyzed in that State shows the following percentages: Nitrogen, 1.86 per cent. ; total phosphoric acid, 11.16 per cent. ; potash, 5.55 per cent. Twelve hundred pounds per acre of a fertilizer of this composition would have con- tained the following amounts of these ingredients, as compared with those contained in the 1,200 pounds of mixed chemicals applied in these experi- ments: Irish PorTraToEsS—253 | Average potato fertilizer.

That is, the average potato fertilizer would have supplied only 44.4 per cent. as much potash as was used with profit in these trials, while it would have supplied 148.8 per cent. as much phosphoric acid and almost exactly -half as much nitrogen. This shows that for some soils the usual potato fer- tilizers are not properly compounded, and makes it all the more evident that the farmer should test the needs of his soil by experiment. The bulletin well remarks that the conducting of an experiment involving only the use of eight small plats, and not necessarily continued more than a year or two, would be a small price to pay for knowledge which may save the unnecessary expenditure of large amounts of money for fertilizing ingredients already present in the soil in more than sufficient quantity. No farmer can afford to spend his hard-earned dollars to purchase fertilizing materials without knowing, first, that he receives the value of his money in a commercial sense, ~ and second, that the material which he buys at a fair commercial price is the exact material needed for his soil and crop. At the Kentucky Station it was shown that an application of acid phos- phate alone made a smaller crop than on the the plat where no fertilizer was applied. Potash applied alone greatly increased the yield, as did nitrogen alone to some extent, but the best results were from nitrogen and votash mixed. At the Ohio Station a comparison was made between the second crop seed potatoes from the South and Maine potatoes. The potatoes from Maine and Wisconsin were considerably sprouted, while the second crop seed hardly showed any signs of sprouting. They were in excellent condition and of the best quality. The yield was slightly in favor of the Southern second crop seed except in the case of the Early Rose. The general average was a little in favor of the Northern seed, the average yield from the second crop seed being 170 bushels per acre and of the Northern seed 171 bushels per acre. In 1894 the average from the Southern seed was 105 bushels per acre and that from the Northern seed 102 bushels per acre. It seemed that for that lati- tude there may be no advantage in the Southern seed, provided the Northern seed is as well kept. In regard to the use of fertilizers on the potato crop this bulletin says: “In the use of fertilizers the lowest cost per bushel of increase in crop has been attained in the use of superphosphate alone, but the greatest gain per 254—Crop GROWING AND Crop FEEDING acre has been with 1,100 pounds per acre of fertilizer containing phosphoric acid, nitrogen and potash. Muriate of potash and nitrate of soda, when used alone, have not given a profitable increase, but have proved beneficial in connection with superphosphate. * Phosphoric acid seems to have been the controlling element in an increase in the potato crop in all of our experi- ments.” This shows the importance of testing the needs of the soil experimental- ly, for, as we have seen in the Pennsylvania experiments, phosphoric acid had less effect than potash alone, and the same was found to be the case in. Kentucky. But in one co-operative experiment given in the Kentucky bulle- tin it was shown that on a soil different from that of the Station the same re- sults were had as detailed by the Ohio Station, showing a great variation in the manurial requirements of different soils, even in the same State. At the Texas Station it was found that potash, either as a muriate or sul- phate, produced a paying crop, and that bone black was the best one-sided fer- tilizer. In regard to the Southern second crop seed potatoes the Texas Sta- tion says: “So far as our experience goes, it seems safe to conclude that sec- ond crop potatoes are as good, if not better, for planting, than Northern grown seed.” CHAPTER XXXVII. SWEET POTATOES. Our sweet potato is a member of the morning glory family and is not of the same family as the Irish potato. Unlike the Irish potato, too, it is a true root and not a tuber, though tuberous in form. The sweet potato de- lights in a warm, sandy soil, and will not reach its best condition in any other, though fair success can be had in heavier loams. Though differing in character from the Irish potato its manurial requirements are very similar. But as the plant grows through the long, hot season, when nitrification is active in the soil and is still further promoted by the rank cover of the vines, the crop needs far less nitrogenous manures than the early crop of Irish potatoes. In fact, any excess of nitrogen will lead to a rank development of tops at the expense of the roots, and while these rank vines are capable of storing large quantities of the starch and sugar so important in the tuberous roots, they cannot do this unless there is plenty of the mineral elements over and above that needed for the perfection of the top-growth. Hence phos- phoric acid and potash are far more important for the crop than nitrogen, and the slowly available organic matter is better than the immediately avail- able nitrogen of a nitrate. While on the northern limit of the culture of the sweet potato it may be desirable to use stable manure in its production, such would be rather a hindrance than a help in the South. The large market growers understand the requirements of the plant very well and they under- stand that the humus forming matter in the rakings of a pine forest are de- sirable as an application to the soil, not alone for their manurial effect but for the mechanical lightening of the soil and the retention of moisture. There- fore the skilled market grower of sweet potatoes uses the forest mold only, as the organic matter, and supplements it with liberal applications of the mineral elements. (255) 256—Crop GROWING AND Crov FEEDING MANURING FOR THE SWEET POTATO CROP. ' There is no doubt that the organic matter needed by the sweet potato could be more cheaply grown on the land by a crop of legumes than by the laborious raking up and hauling and spreading of the forest mold, and it is hoped that the growers will soon find out this fact. There need be no fear that there will be an excess of nitrogen, provided it is balanced by a liberal application of phosphoric acid and potash. It is not the amount of nitrogen that is harmful but the excess in proportion to the other constituents, and a very rank growth of vines may produce a fine crop of roots if the food is at hand which is needed for the storing of starch and sugar. It is the unbalanced ration in the soil that does the harm and not the amount of plant food present. We have explained that in discussing the garden culture of the Trish potato in which similar conditions exist. The rotation of crops and the growing of legumes is just as important to the vegetable grower as to the farmer, and in no way can he so economically stock his soil with the needed humus as by the growing of legumes between sale crops. But no matter whether we haul the rotten leaves from the forest or get the vegetable decay from a crop of pea vines, the getting of it in the soil in abundance is an important matter to the success of the sweet potato crop. Having this organic matter then there will be no need for the application of any nitrogenous fertilizer whatever, except in Northern localities where the - short season requires that the crop be hurried. In such cases the top dressing along the rows of nitrate of soda at rate of 25 pounds per acre at two applica- tions, will be the best. The general mixture for use in the Middle and South- ern States will then be: Acid phosphate, 1,600 pounds; sulphate of potash (high grade), 400 pounds. Five hundred pounds per acre of this mixture will be an abundant dressing for the sweet potato crop. GROWING THE PLANTS. Sweet potatoes are always grown from plants sprouted in the spring from roots kept over for this purpose. That is, these plants are always used for the first planting in the South and for the entire planting in the North. The late crop in the South is produced from cuttings of the vines of the early planted crop. In the North it is the common practice to bed the potatoes in a hotbed under glass, and in the potato growing section of the Middle States fire-heated beds are often used. In the South the bedding is general- ly done in the open ground with a cover of straw to assist in keeping out cold. As the plants cannot be set in the open ground till it is settled and warm, SweEetr Porators—257 it is useless to start the plants too early. There are few localities in the North where it will be available to set the plants before the last of May or the first of June. We have adopted a method of sprouting sweet potatoes which we prefer to any other. We use the ordinary cold frame, and place in it a layer of clean sand. On this we place the small potatoes just near enough not to touch. They are then covered with clean sand about two inches above the top of the potatoes. The sand is settled with a sprinkling of warm water, and the sashes are put on and kept close until the potatoes begin to sprout, when they are opened a little every sunny day to keep the temperature from getting too high. This bedding is done the last of March. We prefer the frame to the manure heated bed, as it is less provocative of fungus growths that dam- age the plants, and though the sprouts are rather slower in appearing they are stout and strong, and in the sand get well rooted, far better than if in a rich soil. If the potatoes are sound and free from disease there will be little dan- ger of “black shanked” plants, and they will be ready as early as it is safe to set them. CULTIVATION OF THE SWEET POTATO. A few days ago a gentleman from Georgia, seeing the low ridges on which my sweet potatoes were growing, was very much surprised. He said: “We throw up large beds with the-plow and then go over them and pull them up higher with the hoe so as to have high beds to set the plants in.” It is strange how long this useless practice has held its ground in the South, in- volving an unnecessary amount of labor and making a less valuable crop. The sweet potato is the one crop for which we always plow shallow, as we want a hard bottom right under the ridge in which they grow so that the potatoes will form short and stout rather than long and crooked. The upper four inches of the soil we prepare as thoroughly as possible, and then lay off furrows, three feet apart, in which the fertilizer is scattered. A furrow is thrown from each side with a single plow, so as to form a list over the first furrow. Just before planting the top of this ridge is flattened with a rake, leaving the ridges only about three inches high. Plants are carefully drawn from the bed so as not to disturb the potatoes, and are set at once with their roots in a bucket of water. They are set thus dripping, are placed so that only the tip of the shoot is above the ground, and the earth is pressed firmly to them. If the land is moderately moist this will be successful without any watering. If planted when the soil is very dry, it is better to pour a cup of water in each hole and at once drop the plant in and cover. Cultivation 258—Crop GROWING AND Crop FEEDING with the small tooth cultivator is begun as soon as the plants get hold of the soil, and is kept up shallowly till the vines cover the ground. The last work- ing is after the vines get quite long. A hand goes ahead and throws the vines over into the adjoining space and the cotton sweep is used to throw a furrow to the row. Each alternate row is thus laid by and then the vines in the other rows are thrown over and the remaining rows earthed up. No hand work is done except to remove any grass or weeds that may appear in the rows. No effort is made to throw back the vines from the last working, as they can wander wherever they list. Some growers go through the field later in the season and pull the vines loose where they have rooted to the ground, but we do nothing of the sort as the labor in doing it is wasted. PLANTING THE LATE CROP IN THE SOUTH. The sweet potatoes from the spring planting of sprouts make the earliest potatoes, but it has been found that those grown later in the season are more easily kept in winter than the spring planted ones. Hence all large growers produce the winter keeping crop from cuttings set in summer from the vines of the early crop. This late crop is grown for two purposes. First, for the production of a crop for table use in winter, and, secondly, a crop of small potatoes for bedding in the spring. For the table crop a piece of land is selected from which some early crop which was fairly well fertilized, has been taken off. Furrows are run three feet apart, and cuttings a foot long of the tips of vines are laid along the furrow slice 15 inches apart, and an- other furrow is thrown on them so as to cover all but the tip of the cutting. Men follow and tramp the earth to the cuttings and the work is done. If the ground is rather moist and the weather favorable nearly every cutting will grow and they are worked just as the first crop. This planting is done early in July. For the seed crop cuttings about a yard long are made in August Ridges are made as for spring planting, the planter coils the long cutting around one hand, and inserts the whole coil in the ground so as to leave only the tip exposed. A cluster of small potatoes will form at every covered joint, and these “slips,” as they are called, make far better and more productive seed for the spring bedding than the cullings from the main crop. HARVESTING SWEET POTATOES. The crop always grows till frost cuts the vines. When the first light frost has blackened the leaves, lose no time in taking off the whole of the vines from the hills, even if you do not dig them at once, for the decaying - SWEET PoTATAOES—259 vines, if left on, will soon affect the roots. Choose sunny and warm, dry weather for digging. Throw a furrow from each side with a small plow and then take the potatoes out carefully in whole bunches, with the forked hoe. Lay them carefully along the rows to dry in the sun, and on no account allow them to thrown in heaps, as that will be sure to bruise them. Gather in baskets and haul to where they are to be stored, handling at all times as care- fully as eggs. The storing is the most important thing in the keeping of the crop. KEEPING SWEET POTATOES IN WINTER. This has always been the great difficulty North and South. Where the crop is grown on a large scale there should always be a building especially constructed for the purpose of wintering the crop. With such a building as we will hereafter describe the keeping in winter is comparatively easy and certain. Late in August, 1900, I met a gentleman in South Carolina to whom I had given directions for a potato house. He told me that the house had been a great success, and that he was then feeding hogs on sweet potatoes a year old, grown in the summer of 1899. The common practice in the South is to keep the potatoes in “banks,” or hills. When well done, and the potatoes are carefully handled before storing, this may be done with very good chance for success. Our method of hilling is as follows. The banks are made, if possible, under a shed open to the south. If no such shelter is available we make a shed at least to keep the rain off. A thick layer of pine straw, gathered in dry weather and kept dry, is laid on the ground, and the potatoes piled in conical heaps on this straw about 25 bushels in a pile. The piles are then thickly covered with the same dry pine leaves, and left till they go through the “sweat,” which they are certain to take when stored. After they have dried off and the weather is getting cool, we cover the heaps with earth lightly, and gradually increase the cover as the weather gets cold, till they have a foot of earth over them. As the shed keeps the rain off the dry earth will keep out any frost, and if the potatoes were free from disease and were carefully handled in storing they will usually keep well. CONSTRUCTION OF A POTATO HOUSE. A heated building for the keeping of sweet potatoes is by far the best method for their preservation. Such a house should not be over ten feet wide, and may be as long as needed, but it will be better not to make it over fifty feet long, if heated by one furnace. Height of the walls is a matter of 260—Crop GROWING AND Crop -FEEDING convenience. The side walls and the roof should be made double and packed with dry sawdust. Along the roof a ventilator should be made, which can be operated from one end with the same apparatus used in the ventilation of a greenhouse. Shelves should be made with slatted bottoms, on both sides of the house, four feet wide and far enough apart to store the potatoes a foot deep. Ina shed at the north end build a brick furnace and take from it a brick flue straight through the middle of the house to a chimney at the further end. Planks can be laid above this flue as a walk in filling and to be removed before any firing is done. Put the potatoes carefully on the shelv- ing, and then start a fire in the furnace and run the temperature up to 90 degrees until all the’sweat is dried off the potatoes, keeping the ventilator open slightly all the time to let off steam. When the potatoes are thoroughly dry, close the house and then only in very cold nights may there be any need for more fire heat. So long as the temperature can be kept up to 50 degrees there will be no need for fire heat, and if the walls are well deadened, in the South this will be easy. In such a house it is perfectly practicable to keep sweet potatoes till the new crop of the following year is large enough for the table. The whole secret in keeping sweet potatoes is to handle them with care and then dry them off as completely as possible, then maintain a temperature of 50 degrees during the winter. SWEET POTATOES NORTH AND SOUTH. There is a wide difference in the character of the sweet potatoes preferred by people in the North and jn the South. Those who grow potatoes for the Northern markets are compelled to grow potatoes which no Southerner will eat if he can help it. The Northern market demands a smooth, yellow potato, with very dry flesh, while the Southerner wants the sweeter sugary and jelly- like “yam.” The Southern yam is not a true yam, but merely a sweet variety of the sweet potato. Tastes of people North and South have been largely formed by their different methods of cooking the roots. Northern people steam or boil sweet potatoes, and the Southern yam is worthless for any such cooking, while the dry and chokey yellow potatoes sold North are well adapted to such a method. A yellow Nansemond, or “Yellow Bark,” as they are called in the South, if cooked by baking as the Southern people always cook sweet potatoes is such a chokey article that it is difficult to eat, while the Southern yam steamed, will lose its sugary character and be a mass of mush. If the Northern users of sweet potatoes would cook the Southern potatoes as the Southern people cook them they would soon find that the dry Nansemonds are SWEET PoTraToEs—261 becoming tasteless to them as they are to the Southerner. When well ma- tured in winter the baked yam, with its jelly-like meat, is adelicious morsel, and far sweeter than any dry potato. But the market grower must consult the tastes of his patrons, and it will probably be a long time before there is « demand North for the vastly superior potatoes the Southern people eat at home. VARIETIES OF THE SWEET POTATO. The most popular potato in the great cities of the North is doubtless the Yellow Nansemond, which is largely grown in New Jersey and Delaware, and a similar potato known in Virginia as the “Red Nose,” which is largely grown in the Peninsula of Virginia for the Northern market. All potatoes of this class are known as “Yellow Barks” in the South, and are there grown only by those engaged in shipping North. In some sections of Virginia a large, light skinned potato with yellow flesh, known as the “Hayman” or “Southern Queen,” is grown both for home use and Northern shipment. It is intermediate between the yams of the South and the yellow barks. This was brought to North Carolina many years ago by a sea captain named Hayman, from Brazil; hence the name, Hayman. Years ago it got into the hands of a Northern seedsman, who introduced it as the “Southern Queen.” It is one of the most productive of sweet potatoes, and is early and the easiest of all to keep in winter. Hence it is well adapted to Northern culture as it can be planted there late in June and make a crop. Of the distinctively Southern varieties the most popular are the “Pumpkin Yam” and “Norton Yam,” with deep pumpkin colored flesh ; the Barbadoes in two varieties, white and yellow, and the Jewell yam, of a yellow color. There is a variety known as “Nigger Choker,” which would suit the Northern taste. It is a deep, pur- plish red on the outside, but the flesh is pure white and very dry, and hence not popular in the South. The most productive of all sweet potatoes is the “Peabody.” This grows to a very large size and is used in the South largely for hog feed, on account of its productiveness. It is too dry and lacks the sweetness which the Southern taste demands, and is only eaten here when partly grown, because it reaches a table size earlier than others and is salable till better potatoes are on the market. There are many other sorts in dif- ferent parts of the South, and a good deal has been said of late about the vine- less yam. The fact is that there are a number of vineless sweet potatoes, or sorts that do not make a running vine, and we have had several varieties to sport into this character among the ordinary sorts. We have failed to see any particular advantage in the vineless sweet potatoes. 962—Crop GROWING AND Crop FEEDING EVAPORATING SWEET POTATOES. There is no vegetable grown that is so easily and rapidly dried as the sweet _ potato. Cut in slices and evaporated in any of the porta- ble evaporators, they can be kept in sacks in winter without diffi- culty, and can be made into a variety of dishes and puddings, after being soaked over night to restore them; or they can _ be pulverized and used for the many nice dishes that the Southern house- wife knows so well how to prepare. We have often thought that if some one would go into the business of evaporating and pulverizing the sweet potato, and then pack them in neat papers, such as corn starch is packed in the North, a large and profitable trade could be established, especially if the packages gave the recipes for custards and pies and such things that the sweet potato makes so perfectly. There is a great opening in the South for the invest- ment of capital in such a business, for the potatoes can be contracted for as cheaply as Irish potatoes are contracted for at the starch factories in Maine. YIELDS OF SWEET POTATOES FROM LARGE AND SMALL TUBERS. The experiments at the Texas Station show that the sweet potato is just apt to produce large crops from smal] tubers, or rather tuberous roots, as from large ones. In fact, the small roots gave the largest yields. Cuttings of the vines set in June were usually smoother potatoes than those raised from the spring plants. They are also much less liable to disease, and hence are better for the seed for the following year. arly plants are set for the pur- pose of giving cuttings for the late crop. The Texas Station also gives the following results from the application of fertilizers to the sweet potato crop: Plat No. Yield bushels. 1 “Nitrate ‘of ‘sodas. 460." TbstROd.

Muriate of potash lowered the yield, and nitrate of soda increased it but once. The special sweet potato fertilizer contained a large percentage of phosphoric acid. The analysis of this fertilizer was: Total phosphoric acid, 8.5 per cent. ; potash, 1.93 per cent.; nitrogen, 0.80 per cent. From -our own experience in the fertilization of the sweet potato we would say that this fertilizer was too low in potash for the best results, on the average sandy soil in which the sweet potato is grown in various parts of the country. It will be found that the sweet potato as grown in New Jersew will bear heavier applications of nitrogen than it will in the South. CHAPTER XXXVIII. TOMATOES. There is no vegetable crop grown that has so increased in popularity in the past forty years as the tomato. The writer can remember when in the markets in the city of Philadelphia but a few bushels could be sold on each market day, and canning was then unknown and few people ate the fruit at all. Now the use of the tomato has grown to enormous proportions, and where fifty years ago a peck would supply a market stall, it would take many bushels today. In many sections the crop has grown to the proportions of a farm crop and extensive fields are planted for the supply of the canning es- tablishments in all parts of the country. Starting in the winter in Cuba and South Florida, the tomato is a staple for the market gardener all up the coast to the most northern point where they can be ripened in the open air. And not only in the open air is the crop grown, but acres and acres of glass are devoted to the forcing of the crop in winter, when the superior quality of the forced fruit finds it a ready sale at prices far above that of the inferior product of Cuba and Florida. There is probably more capital invested in the cultivation of the tomato in the open ground and under glass than any other garden crop. Hence the varying conditions under which the crop is produced should have careful attention. From the tender nature of the plant and its tropical origin it might be supposed that it would be more successfully grown in the South than North; but, in fact, the reverse is true. The crop in the South is never so large per acre as in the Middle and Northern States. The plants are there subject to disease to a greater extent than in the North, and the early crop is generally suddenly cut short by the access of drought and extreme heat about mid-summer, so that while the South can produce an early crop, and can produce the forced winter crop more cheaply than the North, the general crop for canning purposes will probably be always mainly produced in the Middle States , East and West. While farmers in Maryland can grow the fruit on contract for the canning houses at $6 per ton, the man in North Carolina who undertook to do the same thing (outside the mountain (264) ToMATOES—265 country) would not make the cost of his plants. We write this to show that each section of the country has its particular season and crop from the tomato, and that climatic conditions which cannot be overcome, determine to what extent each shall grow the crop. Manurial requirements also vary in the different sections. The amount of manure and fertilizers that the crop absolutely requires in the South would be a disadvantage in its growth in the canning sections of Maryland. GROWING THE PLANTS. o With the advancing season from Florida northward, the sowing of tomato seeds is done at different times. ‘The Florida growers who depend mainly on the advantage of their climate, sow the seeds late in the fall and grow the crop during the winter, taking some risk of frost, of course. As we come up the coast, in sections where frost is certain and sometimes severe in winter, a different method must be used, and the only real difference in the plans of the gardener in the South and in the North is in the time when he sows his seed. In our experience there is nothing gained by sowing the seeds earlier than ten weeks before the time when they can safely be transplanted to the open ground. Every grower will know when this is in his locality, and can make his sowing accordingly. The seed can be sown, of course, in a manure heated hotbed under glass sashes, or in-the far South in a cold frame, to be transplanted as soon as large enough to handle to other frames to develop size and to harden off for planting outside. But we find that when the facilities are at hand a greenhouse is the best place for the sowing of the seed, and every market gardener should have a greenhouse for the early starting of his plants of various kinds, since it is far less troublesome and far less risky than a hotbed. We find that here we can set properly hardened plants the first week in April. Hence we sow the seeds about the last of January in shallow boxes or flats in the greenhouse, where a night temperature of 55 degrees is maintained. They are sown quite thickly, and as soon as large enough to handle and even before they have any but the seed leaves, we trans- plant them to other boxes about an inch and a half apart and set them down to near the seed leaf. As soon as they begin to crowd in these boxes, they are again transplanted into other boxes about two and a half inches apart By the time they crowd each other in these boxes it will be about the first, of March, and then they are transplanted to the cold frames, are given four inches beween the plants, and are set quite deeply in the soil. If severe frost comes, the frames are protected by mats, but the plants are exposed to the air at every favorable time until finally the sashes are left off at night and the 266--—Cror GROWING AND CROP FEEDING plants fully exposed a week or more before finally transplanting. We find that the more frequently the plants are transplanted and the earlier they can be gotten out to stand, the earlier the crop. Tomato plants that are properly hardened off before transplanting will endure a slight frost without injury. Once, in Northern Maryland, we set 55,000 tomato plants in the open ground the last of April, which was a very early date for the latitude, above 39 de- grees. But the plants were large and stocky, and had been carefully hard- ened off in the frames. In the early part of May we had a white frost that covered the plants. The stems turned: blue-black, but they were not hurt, and the result of this risk was that I began to ship tomatoes the last week in June, or nearly three weeks ahead of the gardeners on the western side of the Bay in the same latitude, and for that time I had the Baltimore market for nearby tomatoes all to myself. Some years ago, here in North Carolina, we had an exceptionally warm March. All the earlier part of the month was characterized by hot, summer-like weather, and everything got to growing and the trees leaved out. Concluding that spring was here to stay, I set tomatoes March 17th. On the 25th the Weather Bureau reported frost coming severely that night. I went to work and bent each plant to the earth, covered it with hay and then piled a mound of soil on each plant. The next morn- ing the mercury stood at 21 degrees above zero, but the sun soon warmed things up. The following night there was a light frost and the next day I uncovered my tomatoes and found them all unhurt, and the crop was a very early one. Setting as early as the first week in April we run some risk of frost, but it is far better to stand ready to shovel the earth over them than to keep them inside longer. The same plan can be made available in the North at a later period, and gardeners everywhere will find it a great advant- age to get the plants in the open ground early, provided they have been well hardened in the frames where they were spotted out. The skill of the gar- dener is shown in getting ahead of the growers around him and getting near- hy tomatoes on the market in competition with the inferior fruit shipped from the South. FERTILIZING THE TOMATO CROP. From the fact that the tomato in old and rich gardens sometimes grows so rankly as to be an inconvenience, and noting the occasional pro- ductiveness of volunteer plants that come in the corn field at times, there has grown up a notion that heavy manuring is a disadvantage to the tomato. An accurate study of the manurial requirements of the tomato plant at the various Experiment Stations has demonstrated the fact that special fertiliza- ToMATOES—267 tion is of great value in the productiveness and the early maturity of the plant. Prof. Voorhees recites the results at the New Jersey Station in the use of nitrate of soda as a special fertilizer for the tomatoes grown for the early crop, and that the results showed that when used at the rate of 160 pounds per acre at one application, or 320 pounds per acre at two applications, it increased the yield materially and not at the expense of maturity, and this was also true when it was used in a complete fertilizer mixture, with phos- phoric acid and potash. But when the whole of the 320 pounds was applied at once with a sufficient proportion of phosphoric acid and potash, the yield was increased at the expense of early maturity. It was found that nitrate of soda was better than barnyard manure or mineral fertilizers alone, but when used alone was less effective than when a component part of a com- plete fertilizer. We have found, here, that the best fertilizer application for the tomato crop is made by mixing acid phosphate, 900 pounds; dried blood, 600 pounds, nitrate of soda, 200 pounds, and high grade sulphate of potash, 300 pounds, to make a ton. Of this we would use 700 pounds per acre broadcast before setting the plants. North of Virginia we would reduce this to 500 pounds per acre. When growth is well under way, and fruit is setting, we find it an advantage here to give a further dressing of nitrate of soda at rate of 100 pounds per acre. On land that had been heavily manured the previous year for garden crops, or on which a crop of legumes had been grown the previous season, we would reduce the amount of the dried blood and increase the amount of acid phosphate proportionately, or would substi- tute cotton seed meal for the dried blood. A light, mellow loam inclined to sand is the best soil for the early tomato crop, and it is useless to try to grow it on a heavy clay or a cold and poor soil. As to the source of the plant foods used, the nitrate of soda and the dried blood we prefer as the sources of nitrogen, and we think it an error to depend on nitrate alone for this crop if a continuous growth and productiveness is desired. The phosphoric acid canebe supplied by superphosphate made from rock, or bone black, as may be most available in the locality, and the potash is best furnished by the sulphate free from chlorides. In any crop in which sweetness of the fruit is a desirable feature we have found the sulphate the best form in which to use potash. If it is desired to get the best use of the nitrate of soda it would probably be better to mix the other constituents and reserve this to be applied alongside the plants after setting. But the second application of the nitrate should be over the entire surface, since by that time the roots are running far and wide. Where stable manure is abundant and cheap we would greatly prefer here to plow under a heavy coat, mix it well with the soil, and then add simply the phosphoric acid and potash, with a 268—Crop GROWING AND Crop FEEDING light dressing of 50 pounds per acre of nitrate of soda at time of setting the plants, on the surface around them, but not in contact with the roots. © No further dressing will be needed and for this climate this is far better than a heavy application of a complete commercial fertilizer. In old gardens that have been manured for years with stable manure, we would use no nitrogenous fertilizer whatever, but would use a good dressing of acid phosphate and potash, say 400 pounds of acid phosphate and 100 pounds of sulphate of potash per acre. We would note that in the South the organic forms of nitrogen in a tomato fertilizer are of far more importance than in the North. Otherwise, in the very hot weather we are apt to have in June, the plants will fail if no nitrogen but that from the nitrate is at hand. In the North the case seems different, and it is found undesirable to keep up too much growth rather than devote the whole energy of the plant to fruiting. THE FIELD CROP OF TOMATOES. This crop is produced for the canning establishments, and earliness is not an object. The plants are grown in beds in the open ground and trans- planted to the field when large enough, setting them in rows five feet. apart and four feet in the rows. Cultivation is as for a crop of corn. The same fertilizer mixture advised for the early crop will do as well for the canning crop, but the second application of the nitrate of soda will not be needed nor profitable. On soil that will make a good crop of corn 500 pounds per acre of the mixture will be ample. We have found that for this summer crop a top dressing of stable manure between the rows is a great advantage in our dry and hot summers, as a mulch as well as plant food. Prof. Vor- hees shows that a good crop of ten tons of tomatoes per acre, with their vines, would contain 57 pounds of nitrogen, 16 pounds of phosphoric acid and 94 pounds of potash. This shows very well the relative importance of the differ- ent food constituents, and that nitrogen and potash are the largest part of the food consumed by the tomato. THE SOUTHERN BLIGHT. While this work is not intended to take up plant diseases, which would take a volume for the proper treatment, we must, nevertheless, say a few words in regard to this terror of the Southern tomato grower. There is more than one blight which attacks the tomato, but the one known distinctively as the “Southern blight” is a bacterial growth in the tis- TOMATOES—269 sues of the plant, and the first intimation of its presence which the ordinary observer has is the sudden wilting of a large plant full of fruit. If the wilted plant is allowed to remain, the disease extends to others till the whole may be destroyed. It is the great bane of the Southern tomato grower, but unfor- tunately no sure preventive has as yet been discovered. A year ago we gave a piece of ground, where tomatoes had blighted badly the year before, a dressing of lime at the rate of about 30 bushels per acre, and set it again in tomatoes. There was little or no blight that season. This year we set the same plat in tomatoes without any further liming; every plant died from blight. So it would seem that whatever influence the lime had in the pre- vention of the blight was but temporary. Hence the only advice we can give is to avoid land where tomatoes, potatoes or watermelons have been lately grown; as all of them, with the egg plant, are subject to the same disease. The soil gets infected and any remedy that is to be effectual must deal with the soil. Fresh soil from the forest should be used for the growing of the plants for the infection doubtless takes place at an early stage of the growth of the plant. VARIETIES OF TOMATOES. These are now so numerous that the inexperienced planter is often puz- zled to know what sorts will be best for him to plant. The tomato yields so readily to selection and breeding that the varieties do not long retain their original character. The names of old varieties are continued on the lists of seedsmen, but they are far from being the same as they were when first sent out. One man forms an ideal of what he wants in a tomato, and works at it till he gets nearly what he is after, and the tomato is put into commerce. Then other growers go to work to produce it for the trade, but they work on entirely different ideals from the originator, and the variety in the hands of one grower is still further improved, and under the treatment of another is al- lowed to deteriorate; but both are sold for the same thing year after year. The Trophy tomato, for which we paid to the late Col. Waring $5 for twenty seeds, is still on the seed lists, but it is no longer the Trophy of Col. Waring ; some stocks have run back while others have been selected to an entirely differ- ent type. The earliest and most productive tomato we have ever grown is the variety known as Maule’s Earliest. Its fault is lack of smoothness, especially in the earliest syecimens. We are at work on this tomato, and hope to evolve from it a tomato with a smooth skin and still as early and prolific as the present type. Fordhook First is another very early tomato of a different type. Atlantic Prize is early but small and unproductive. Early Ruby is 2%0—Crop GROWING AND Crop FEEDING very early but is also, in our experience, rough and a poor cropper. For the main crop and for canning Livingston’s Beauty, Matchless, Crimson Cush- ion, Stone and Queen are all good. FORCING TOMATOES IN WINTER. There are few varieties well adapted for this purpose. The one known as Lorillard has been more generally used than any other. If we can suc- ceed in getting a smooth type of Maule’s Earliest it will leave nothing to be desired in a forcing tomato. Dwarf Champion, while not usually recom- mended for forcing, has, with us, always beaten Lorillard, and we are in- clined to consider it one of the best. ‘Tomatoes for forcing are sown about the last of August for the first crop. We sow the seed in the open ground and transplant them there once, to get them stocky. They are potted in four- inch pots late in September and transferred to a greenhouse where the night temperature is not over 55 degrees, if possible, at this season. They are kept close to the glass to keep them stocky. As soon as the balls are well covered by the roots, but before the plants got “pot bound” or stunted, they are trans- ferred to the fruiting pots. We always grow tomatoes in pots. Some use large wooden boxes for them, and some plant out on the benches in soil over the hot water pipes. If the crop is being grown commercially, and the house is a narrow lean-to constructed for the purpose, the planting should be on the benches in a bed of soil and the vines trained on wires in the same way we train grapes under glass. But in a span-roof greenhouse, where the glass is used later in the season for other purposes, the pots are far more convenient and for the one crop fully as good. We transfer the plants from the four- inch pots to those of ten-inch size. Arranging for drainage at the bottom we place the plant near the bottom of the pot and fill around with soil merely to the height of the ball turned from the four-inch pot. Then, as soon as the white roots are seen running into the fresh soil, another inch of compost is added, and so on till the pot is filled enough. This gives the plant a very strong root system. When the pot is well filled with roots we give dilute manure water, or nitrate of soda one ounce to a two gallon can of water, week- ly. The plants are trained to a single stem and all side growths rigorously pinched out. When placed in the fruiting pots the plants are put into a house where it is possible to maintain 70 degrees at night, though 60 is about the usual average. As soon as the blossoms set we go over the house daily at noon and brush the pollen on the stigmas with a soft camel’s hair brush. This is more rapidly done and is far more effective than any effort to collect pollen in a spoon, as some advise. The early crop should begin to ripen about ToMATOES—271 Christmas and will continue into March. If the house is to be used for toma- toes entirely, another crop should be coming on to take the place of those that are exhausted, and the seed for this is sown in early December, and will make a crop to follow on till tomatoes are ripe in the open garden. With the proper structures for the purpose the winter crop of tomatoes can be made a very profitable one, as we have sold them right alongside the Florida tomatoes for 25 cents per pound, when the Floridas were selling for one-fourth the money. ‘The superior quality of tomatoes grown under glass attracts at- tention at once. There is no vegetable plant more generally forced than the tomato and none that has been more uniformly profitable when forced; nor is there any crop grown that so readily responds to commercial fertilizers. We have had a long experience in growing winter tomatoes and much prefer to use commer- cial fertilizers than stable manure for them. In fact, the only real failure we ever made was from using stable manure exclusively in our compost, and a liquid manure of cow dung instead of nitrate of soda. We got a tre- mendously rank growth but a very poor bloom and fruitage, and we have dis- carded manure in the culture of tomatoes under glass. If the potting ma- terial known as jadoo fibre was funished more cheaply we would prefer it to any soil mixture we have ever tried; but the commercial grower cannot afford to use it at the price charged. The best soil is made from sods from a mellow loam pasture, piled and rotted one summer in advance of use, and frequently turned till it is perfectly fine and homogeneous. We have always had better success with plants grown in ten or twelve-inch pots than with those planted out in beds. Wooden boxes may be substituted for the pots if desired. We sow the seeds for the winter crop about the last of August, and as soon as large enough pot them into three-inch pots and set them in 2 frame where they can be watered regularly. As they fill these pots they are transferred to four-inch pots and replaced in the frame. As the nights get cool we take the plants into the house and put them in their fruiting pots. In these pots we use plenty of broken crocks for drainage and cover the drain- age with moss to prevent the soil choking it. The large pots are only filled enough to cover the four-inch balls at first, and as the roots are seen on the surface of the soil another layer is added until finally the pot is sufficiently filled. In this way the roots get complete possession of the soil. I should have said that in this soil we use a liberal mixture of raw bone meal, which furnishes nitrogen and phosphoric acid in sufficient quantity to keep up a fair growth. As soon as the plants show bloom we go over them daily at noon and apply the pollen to the stigma of the blossoms with a camel’s hair brush. If this setting of the flowers is neglected there will be little perfect fruit, 2%2—-Crop GROWING AND Crop FEEDING and what there is will be small and seedless, for under glass there are no in- sects to do this for us. As soon as the roots can be seen to have taken pos- session of the last layer of soil we begin to use liquid fertilizer, made by dis- solving one ounce of nitrate of soda in a two gallon can of water, and give this once a week. Do not begin this till you see that the roots have possession of the soil, for there is otherwise a tendency to sour the soil. The plants are kept trained to a single stem and two feet square is allowed to each plant. Daily attention is needed in pinching out the side shoots and keeping the plants to a single stem. Pinch these out as soon as seen, so that all the strength of growth will be thrown into the main stem. The stems are trained to strings or wires from the roof above. When the stems have reached the height of the house the ends are nipped and no further development allowed. In the meantime, about the middle of December, sow seed for a succession crop to replace these as the crop is gathered. These succession plants can be grown on the side benches of the house until they are ready to take their places in the fruiting pots. The tomato house should be kept during the fall and warm weather, well ventilated, and when the nights get frosty a little fire heat is given, so that the temperature does not go below 55 degrees. As the plants get into bloom the temperature of the house should never he allowed to go below 60 at night and should be kept, by ventilation, at 80 or less in day time. The tomato under glass is subject to the attacks of fungus diseases, the worst being the Cladosporium Fulvum, which attacks the leaves, begin- ning on the lower leaves, and if not checked will defoliate the entire house. We manage to keep clear of it by painting the hot water pipes at times with a solution of the sulphide of potassium, and by keeping sulphur scattered around under the leaves in the sun, so that it gradually evaporates in the air. These precautions should precede any attack, for if the fungus once gets started it is hard to stop. Some recent experiments have shown that when the tomato plants are planted in pure coal ashes and supplied with the proper fertilizers the result- ing crop has been better than when grown in the most carefully prepared compost. Whether this will be true in all cases or not we cannot say, but there seems to be a sort of affinity between coal ashes and tomato plants, for the most wonderfully prolific and long lived tomato plant we ever saw grew in an old heap of coal ashes, where it started as a volunteer and was allowed to remain. While coal ashes have little of what is classed as plant food in them they do certainly assist in the mellowing of the soil and the retention of moisture. We have greatly improved a piece of stiff clay soil by heavy dress- ings of coal ashes, and nowadays we never throw them away, but always find use for them. One of the most valuable uses for coal ashes is for plunging ToMATOES—273 plants in pots in the cold frames. A bed of coal ashes makes the best place in which to plunge pots to save watering and to protect them from frost. Pots set upon the ground soon get filled with earth worms to the detriment of the plants, but when set on coal ashes or plunged in them the worms have no chance, for they will not crawl through the ashes. ‘Then, too, there is no inducement for the roots to run out through the hole in the bottom of the pots, as when they are placed on soil, and if any do get out they are easily removed from the ashes entire. Coal ashes applied to a sandy soil will make it more retentive of moisture and less inclined to be leachy. THE FORCING HOUSE FOR TOMATOES. For the purpose of winter forcing tomatoes we prefer a full even-span house twenty feet wide, with a space in the centre for setting the boxes of pots, and benches on the sides that can be used for the forcing of beans or other dwarfer growing plants, that need about the same temperature as the toma- toes ; or for bringing on the second crop for the replanting of the house. The house should be not less than ten feet to the ridge in the centre, the glass should have a slope of 45 degrees, and the house should run north and south so that both sides will have sun at different times of the day. A narrow lean- to house may be used and the plants set on the front bench and trained on wires under the glass, as we do grapes, but in this case the slope of glass should be to the south. In a very narrow house of this kind, with the glass a steep incline to the south, the crop may perhaps be earlier in setting and the house more easily heated than in the span-roof house, and the second crop may be started against the back wall and get the sunlight after the front vines have been taken out; but we greatly prefer the span-roof house. In such a house, with each plant trained to a single stem and allowed two feet square of space, there should be, during the winter, a crop of two pounds for every square foot of space in the house. The crop here usually commands 25 cents per pound in winter, hence a house with 1,000 square feet of surface should produce 2,000 pounds of fruit, worth $500. Whether such a crop will be profitable or not will depend on the cost of heating the house, and here the Southern forcer will have a great advantage over the grower in the colder sections, in the fact that he needs to use less coal and has far more sunlight in winter, and sunlight counts for far more under glass than does fire heat. It is probable that the best style of house, though we have never tried it for the tomato, would be that known generally as the Rose house, because it is the form generally adopted for the winter forcing of roses for cutting in winter. The shape of such a house is what is called three-quarters span ; that 2%4—Crop GROWING AND Crop FEEDING is, there is a high back wall and a low front one, a short slope of glass on the back and twice as long a slope in front. Then if the benches are made at different heights the plants can be brought to uniform distance from the glass and all have an equal chance at the sunlight. Prof, Bailey says that he prefers to grow tomatoes on the side benches in 7 or 8 inches of soil and on benches, too, in the centre of the house. Our objection to this would be that the tomatoes on the side benches would too much shade those in the centre. While in all the earler stages of the growth of the plants the house should be kept moist, very great care is needed in the watering of the plants. We keep the walks damp at all times and water the pots only when needed, having no set time to do this, but varying with the state of the weather and the amount of sunshine. A slight thump on the side of a pot will tell if water is needed even when it looks moist on the surface. If the pot sounds hollow water should be given, if not, none. Moisture is maintained by water- — ing the sand on the benches where the pots stand, and watering the walks, but sprinkling overhead on the plants is never done. Various plans have been proposed for the pollenation of the flowers, such as shaking off the pollen in a spoon or watch glass, but we have never succeeded in this, and find no difficulty in rapidly setting the flowers with a camel’s hair brush. Prof. Bailey says that all varieties of tomatoes are more inclined to be irregular in shape under glass than in the open ground. We have found the very re- verse of this to be the case. They always, for us, grew more smooth and per- feet under glass than out doors. Perhaps the difference is climatic and due to our abounding sunshine, even in the coldest weather. He, too, claims that the Dwarf Champion is the least satisfactory under glass, while here it has always been one of the best, while-the Lorillard, which is claimed in the North to be a special forcing variety, is an utter failure here every time it has been tried; the poorest crop we have ever had was with this variety. Forced tomatoes are marketed in baskets similar to those used by the Florida shippers, and packed in what are known as Southern carriers. Hach fruit should be wrapped in soft tissue paper, and the baskets lined with white paper, and with some clean excelsior shavings under the fruit to prevent jarring in transportation. COMMERCIAL FERTILIZERS IN TOMATO FORCING. Our own experience in the winter forcing of tomatoes has led us to prefer chemical fertilizers to stable manure. On this point we are glad to refer to the work done at the Connecticut Experiment Station as detailed in their report for the year 1895. “To those who are raising or contemplating rais- ToMATOES—275 ing winter crops under glass, the question of substituting fertilizers for ma- nure, in part at least, is a very important one. Forcing house soil as usually prepared, consists of rich garden soil or rotted turf, composted with from one-fourth to one-half its bulk of horse manure. Aside from the labor of hauling and repeatedly working over this material to secure the fine mellow condition which is desired, the cost formerly was not great. But the in- troduction of electric cars enormously cut down the production of horse manure in the cities, which has been the main dependence of our market gardeners. In consequence, the preparation of suitable soil for forcing houses is increasingly expensive. Besides this it is found that even a rich natural soil cannot carry forcing house tomatoes to their highest productive- ness, and therefore liquid manure is often used to water the soil after the plants have come into bearing. The admirable work on the use of commercial fertilizers on field tomatoes, done at the New Jersey Station, has proved that the ripening of the crop may be very materially hastened by the proper use of fertilizer chemicals, especially of nitrate of soda. To hasten the ripening of crops under glass, where the expense of growing them is so much greater than in the field, must greatly increase the profits of the business. A further question also connected with these, is, whether the humus of rotted manure, generally regarded as necessary to regulate the storage and circulation of moisture in the soil under natural conditions, can be replaced by some cheap substitute, or dispensed with altogether in forcing- house culture, where the supply of soil moisture can be well regulated by artificial means. : “Our first endeavor was to find out how much nitrogen tomato plants — raised under glass take from the soil, in their fruit and vines, and how much nitrogen needs to be in the soil to meet fully this demand of the plants. These questions we studied by raising tomatoes on the forcing- house bench filled with soil known to be practically free from available nitro- gen, but believed to contain all other ingredients necessary for a maximum tomato crop. To these plats were added known quantities of nitrogen in the form of nitrate of soda. The weight of the fruit harvested, and of the vines which bore it, with the chemical analysis of both, furnish the means of deter- mining how much nitrogen, phosphoric acid and potash a crop of tomatoes takes from the soil. Comparison of the quantities of nitrogen applied to the several plats, with the weights of the crops ard of their nitrogen, gives some indication of the amount of nitrogen necessary to apply in order to secure a maximum crop.” The house used in the experiments was specially con- structed and was a three-quarter-span-roof house, 16x40 feet running east and west, with a partition across the centre, making two apartments. The 276—Crop GROWING AND Crop FEEDING ~house is heated by steam from a boiler that heats all the Station buildings with a pressure of five pounds The steam enters the house, passes over- head to the further end and then returns in pipes under the benches. Venti- lation is by a continuous line of ventilating sashes along the south side, hinged at the top. North and south walls are both solid (without glass). The front wall is twenty-one inches above the top of the bench, and the back wall thirty-eight inches. The experiments were made on the centre bench of the house at the east end section. This bench is nine inches deep, with a bottom of six inch boards laid three-fourths of an inch apart for drainage, the cracks being covered with coarse peat so that none of the soil could escape. Five plats were made, each three feet six and one-half inches by three feet eleven inches, having an area of 13.87 square feet. The soil was filled in to the depth of eight inches, leaving room for settling after watering, and six plants were set in each plat. “The soil for each plat was separately mixed, as follows: 300 pounds of anthracite coal ashes, sifted to pass a wire screen with four meshes to the inch, were spread on a cement floor, and 9 pounds of peat moss, such as is sold in the cities for stable bedding, screened like the ashes, were scattered over them. ‘To these were added three and a half ounces of precipitated carbonate of lime, to neutralize a slight acidity of the peat and give to the whole a mild alkaline reaction. ‘These materials were shoveled over twice carefully and then spread as before. “The fertilizers designed for the plat were sprinkled over this mixture and the whole carefully shovelled over twice again, to secure as perfect a mix- ture as possible of fertilizers and soil, and then carried in a hand barrow to the designated plat in the forcing house. “The north bench in the same division of the house was filled with a rich soil prepared by composting good thick turf with one-third its bulk of stable manure. Plants were set in this bench mainly to make a rough comparison between crops grown on the two radically different soils. The exposure of the two benches is slightly different, that of the north bench being, perhaps, some- what less favorable as regards light. “Three varieties were used: Ignotum, Acme and Dwarf Champion, two plants of each variety being set in each plat, and all receiving the same treat- ment. The method of training adopted was the single stem system, which has been successfully used at the New York Cornell Station. By this system ‘plants can be set closer, and while the yield may be much less per plant than under other systems of training, it is as large or larger per square foot of bench area devoted to the crop. The plants blossomed soon after setting. The first pollenating was done January 5th. Pollenation was effected by ToMATOES—277 holding a spoon directly under,each flower and gently tapping the upper part of the blossom with a pencil or small stick. Pollen is thus shaken into the spoon and at the same time the stigma is driven into the mass of loose pollen in the bottom of the spoon. The stigmatic surface which is on the end of the style is thus coated with pollen, and as flower after flower is visited on many different plants, cross fertilization is insured. Flowers were pollenated about every other day throughout the blossoming period.” All the plants grew finely for a while, though as early as the 8th of Janu- ary there was observed a shght difference in the color of the plants in the plat which had received no nitrate of soda, and this difference of a lighter color increased during the season. First ripe fruit was on the 27th of February, being three [gnotums in one plat and one in another, both of the artificial soil, and two Ignotums and three Acmes from the natural soil. Temperature ranged from 60 to 65 degrees at night and often on warm sunny days 85 to 90 degrees Fahrenheit. The following summary is given of the results: 1. A forcing-house tomato crop yielding about two pounds of fruit for each square foot of bench room, takes in the vines and fruit, for every hun- dred square feet of bench space, not less than: Grams Lbs.

In a further discussion of the subject the Connecticut report says that they are not ready from one experiment to recommend a departure from 278—Crop GROWING AND Crop FEEDING present methods, but they feel justified in calling attention to certain appar- ent advantages of the artificial soil for forcing purposes. For every 100 square feet of bench space there will be required 2,200 pounds sifted ashes and 63 pounds of dried peat or leaf mold to fill the bench 8 inches deep, and experiments may show that the peat is not necessary About , 10 pounds of commercial fertilizers are needed for this much bench space, cost- ing at present ton rates less than 21 cents. In very many cases, then, the cost of filling the benches with the artificial soil will be very much less than the cost of fillmg them with rich garden soil or compost. The tomato plants grown in natural soil made much slower growth and were slower in fruiting than those in artificial soil supplied with nitrates. Another consideration is the freedom from insects and fungi in the ashes, which constitute 97 per cent. of the bulk of the artificial soil, and even the peat which is hardly needed, is not so apt to convey these as the rich garden soil. It was found that there was a special freedom from the nematode worms which cause root galls on plants. The rich garden soil becomes so infested with these that it cannot be used for tomatoes more than one season. In the artificial soil no nematodes were found beyond the ball of earth set with the plants, but they were very abundant in the natural soil. We have given such full space to the tomato because, for both culture in the open ground and under glass, it is about the most important of our vege- table crops. It will readily be seen from the experiments of the Connecticut Experiment Station, which we have given in detail, that the manurial re- quirements of the tomato are mainly for nitrogen and potash, and it may be remarked that this is the case with a large proportion of our garden crops, few of which, if we except the cruciferous family, the cabbage and its allies, require such a large percentage of phosphoric acid as is usually found in the various brands of fertilizers sold ready mixed on the market. SHALL TOMATOES IN THE OPEN GROUND BE PRUNED? We have made a number of experiments in the pruning and training of tomatoes. In the house, before the plants go into the frames, we do not hesi- tate to top them if they threaten to get too tall, but we had rather not do this, and would try to keep them growing slower. In the open ground there have been numberless contrivances invented for the support of the plants, and we have tried different methods of training and pruning. The conclus- ions we have arrived at are these: When tomatoes are grown on a large scale for market it will not pay to prune them or to make any effort to support them. The rot is not caused by the tomatoes touching the ground, but from TOoMATOES—279 the attacks of a specific fungus disease, and if we ward off the attacks of dis- ease, there will be no rot, even though the fruit may rest on the ground. I have often gathered the finest of tomatoes half buried in the soil. Begin the spraying with Bordeaux mixture as soon as the tomatoes are set, keep it up at intervals till the fruit is half grown, and there will be less rot than if they are trained off the ground and no spraying done. It is an advantage, . of course, in small gardens where space is scanty, to plant close like we do in the forcing-house and train to single stems supported by stakes, and in this way a larger crop may perhaps be gathered from a limited space by the use of more plants. Where a support is used the best thing we have ever tried for the support of anything in the garden needing it, is the wire poultry net- ting, now sold in various widths so that it can be adapted to plants of various heights. Stretched to stakes along the row the tomato plants can be pruned to a single stem and set two feet apart in the row, there is always a point to tie to, and the leaves, growing through the meshes will of themselves aid in the support of the plant. While in the North it is perfectly practicable to carry the early forwarded plants through the whole season it is not so in the South, for the early plants of the garden are usually either checked badly or killed by the heat and drought we usually have about the last of June. If we then do not have a_ supply of fresh plants coming on from seed sown in the open ground in April, there is apt to be a cessation of tomatoes; so we always try to provide this set of plants, and these, too, will usually fail by the late fall; hence we have adopted the plan of sowing seed for a third crop about the first of June. These plants get the advantage of the rainy season we usually have during July and August, get into full fruiting in the fall, and are generally full of green fruit when frost comes. We usually get more tomatoes from these plants than from either of the other sowings, for when the frost comes we gather all the green tomatoes and wrap them singly in paper and pack in boxes and place in a room where they will be kept cool but clear of frost. Then a few are taken out from time to time and placed in a warm room, where they soon color up and are ready for the table. In this way we are able to keep up a regular supply of tomatoes for slicing, till the forced tomatoes of the hothouse are ready in January. On a large scale we are sure that this late crop might be made a valuable one in the South, as the fruit can be had in good condition for shipping, and better than the Florida crop, about the Christmas holidays when they will bring a good price. One would sup- pose from the tropical nature of the plant that the tomato would be a more successful crop in the open ground in the South than in the North, but, as we have shown, the difficulties in the growing of the crop increase as we come 280—Crop GROWING AND Crop FEEDING southward, and the quality of the product in the open air is not equal to that of the Northern crop. But in the forcing-house we have a great advant- age over the Northern grower, and we have treated of this part of the subject fully because we believe that winter forcing in the Upper South is destined to become a great interest. FURTHER REPORTS ON CHEMICAL FERTILIZERS IN FORCING TOMATOES. In the report of the Connecticut Station for 1899 we find the following statements. In the season of 1897-8 two crops of tomatoes were forced, and the compost and coal-ash beds were made to alternate with each other through the house. 'T'o each plat of coal ashes and peat were added 411.64 grams of nitrate of soda, 700 grams cotton seed meal, 141.36 grams dissolved bone black, and 215 grams of muriate of potash. For the second crop the amounts of these removed by the first crop were added. ‘The application was too heavy and the plants were injured by it. In 1898-9 nitrogen was furnished to the plats of coal ashes and peat with same materials and also with bone meal. The yield from the plats dressed with bone was below that of the others. The soil of coal ashes and peat made a heavier yield of tomatoes than the pot- ting compost, and the same result was found in all the crops. CHAPTER XXXIX. SOME SPECIAL FORMULAS FOR TRUCK CROPS.

In a bulletin published in 1893 the Ohio Station, from a series of four years experiments, concludes: “While, therefore, these experiments demon- strate the possibility of producing a regular and certain increase in the yield of cereal crops by the use of a complete chemical fertilizer, yet they show that if such fertilizers are to be used in Ohio in the production of cereal “crops with any prospect of profit and as a part of a regular system of agri- culture, that system must provide for the accumulation in the soi! of the largest possible quantity of organic nitrogen, through the culture, in short rotations, of plants which have the power of obtaining nitrogen from sources inaccessible to the cereals.” The following year the same Station made the following additional statement: “At the present prices of cereal crops and of fertilizing materials respectively the profitable production of corn, wheat and oats upon chemical or commercial fertilizers, or upon barnyard manure, if its cost be proportion- ate to that of the chemical constituents of fertility found in commercial fertilizers, is a hopeless undertaking, unless these crops be grown in a sys- tematic rotation with clover or a similar nitrogen-storing crop; and the poorer the soil in natural fertility the smaller the probability of profitable crop production by means of artificial fertilizers.” All of which makes more emphatic what we have said in regard to the need for the renovation of the soil and the storing of it with humus, through the growing of cow peas or clover, thus making it not only richer in the nitrogenous matters, but making it more retentive of moisture for the proper dissolving of the chemicals applied. The richer the soil in humus the more lavish may the application of fertilizers be made with profit. And yet all over the South there are thousands of farmers dribbling a little fertilizer on soil almost barren, for the purpose of growing a little more cotton without ever inquiring whether or not the increase in the crop pays for the fertilizer.

Then, too, the phosphoric acid could be more cheaply gotten in South Carolina dissolved rock than in bone black, though the percentage might not have been so high, but as the percentage of phosphoric acid is too high anyway, this would be no disadvantage, unless the soil is known to be very deficient in phosphorie acid.

We are of the opinion that the yield must have been much above the average and the price of the crop. still further above the average for the farmer to have gotten the cost out of the crop. The same grower stated that this formula, applied at the rate of a ton per acre, produced a yield of 280 bushels of potatoes per acre on an old sandy-loam pasture. This would not have been considered an extraordinary yield for such fertilization by the grow- ers of the early potato crop in the South Atlantic coast, and it would have been more satisfactory to know how many potatoes could have been grown on the old sod without such a heavy application, for it is not the largest crop that is always the most profitable.

From repeated inquiries made in many sections of the State it appears that the beneficial effect of wood ashes is, almost without exception, attributed to the direct manurial action of the potash which they contain, yet it is usual to hear that the effects from a single application are often visible for from ten to fifteen years. When we consider, however, that 100 bushels of ashes weighing about 4,500 pounds would, upon the average basis of 5 per cent. of potash, contain but 225 pounds of actual potash, which is equivalent to but 450 pounds of muriate of potash, it would seem at least astonishing that an after-effect from such an application should be visible for from ten to fifteen years unless it were due in a considerable measure to something other than the small amount of potash it contains. An appli- cation of a ton of potato or vegetable fertilizer containing 10 per cent. of pot- ash would supply 200 pounds of potash, equivalent to 400 pounds of muriate of potash, or an amount nearly equal to that supplied by 4,500 pounds of wood ashes; and yet we practically never hear of any long continued after effect from the use of muriate or sulphate of potash, or of chemical fertilizers which contain them. Wood ashes contain on an average about 1.5 per cent. SoME Stration INVESTIGATIONS IN FERTILIZERS—291 of phosphoric acid, which would amount to an application of 67.5 pounds of phosphoric acid for each 4,500 pounds of wood ashes, an amount equivalent to what would be furnished by about 300 pounds of fine ground bone. Now if the action of the ashes is based upon the combined manurial effect of the potash and phosphoric acid, then 450 pounds of muriate of potash and 300 pounds of ground bone would be expected to exert an effect analagous to that obtained from the wood ashes. As a matter of fact we believe that the farm- ers of Rhode Island and many other parts of New England have obtained results with wood ashes which are not due to, and which doubtless would not be attainable, by the use of the quantities of muriate of potash and bone above mentioned. It would appear to be equally unsatisfactory to attribute the beneficial action of wood ashes solely to small quantities of magnesia, soda, or whatever else they may contain, regardless of the lime. The experiments thus far conducted at this Station, as well as others at Hope Valley and Wes- terly, together with experiments by farmers in West Kingston, Usquepaugh, and several other localities without the State, point strongly to the value of lime on many soils; not only as direct plant food, but also in putting the soil into a condition suitable for the growth of certain plants, and into such a condition that the nitrogenous plant food stored up in the soil, as well as that in organic nitrogen and ammonium sulphate employed, may exert its maxi- mum effect. In this connection, also the well known value of lime in improy- ing the physical condition of sandy as well as clayey soils should not go un- mentioned. In other words, our experience and observation in this State leads us to believe that the chief cause of the long continued after effect of wood ashes is the lime which they contain and not the potash, as has been heretofore generally supposed. Certainly if such is the case it behooves the farmers of the State to try. the lime experiment for the purpose of testing this question, for the same amount of lime and other fertilizing elements which wood ashes contain can be purchased in other, probably equally effective, forms at a lower price. It will be evident from what has just been said, that wood ashes contain but little phosphoric acid, and it is also true that they contain no nitrogen. Therefore if they are to be used on a rational and economical basis they must be supple- mented by phosphatic and nitrogenous fertilizers. The following materials used upon one acre would be about equivalent, so far as concerns potash, phos- phorie acid and nitrogen, to one ton of fertilizer containing 10 per cent. of potash, 6.5 per cent. of available phosphoric acid, and 4 per cent. of nitrogen: oo 1S lg A et SR Si 4000 pounds © Dissolved phosphate rock ........ 1000 pounds Nitrate of sodaiiis2...0100 227007 510 pounds 292—Crop GROWING AND Crop FEEDING Practically the same amount of lime and other ingredients would be con- tained in the following: Air slaked Jim) 2): 2 oc). -.0:0 «0:0 sfasaisiels 2000 pounds Dissolved phosphate rock ........ 1460 pounds Muriate of potash................ 400 pounds Nitrate of soda........ pas OG 510 pounds.”’ All of which we assume is probably theoretically true, and yet in the effort to make an artificial substitute for the wood ashes, would there not be a danger of a great loss of nitrogen? We are of the opinion that these matters may well be applied to some soils, but that the fertilizing chemicals should be mixed and applied, and the lime applied separately and not in mixture with the fertilizers. So far as the long-continued after effect of the wood ashes is concerned, we are of the opinion that the Rhode Island Station is to a great extent correct in attributing at least part of it to the lime they con- tain, and especially we would add to the extremely fine condition in which the lime exists in the wood ashes. But we consider it an error to advise the use of air slaked lime as an application to the soil. Freshly water slaked lime is far better. Then, too, while ashes have a long after effect, we cannot agree to the statement that similar after effects are not found from applications of potash salts and phosphoric acid. In a considerable section with which we are familiar the long continued use of phosphoric acid to the soil has resulted in an accumulation, so that farmers there no longer find any effect from new applications of superphosphate, and it is a well known fact that potash ac- cumulates in a similar manner. To the following remarks from the Rhode Island Station we heartily agree: “Barnyard manure contains relatively more nitrogen than potash, and is notably deficient in phosphoric acid, so that if the manure is to be used on the most economical basis a small amount of potash and a much larger quantity of phosphoric acid should be used in connection with it. Owing to the great variation in the composition of such manure, depending upon the cattle food used, the care of the manure, and the amount of foreign matter mixed with it, no attempt to give the exact amounts for use will be made. A motto in relation to manures which should find its place on every farm would read somewhat as follows: Save what you have, supplement it wisely and buy economically.” We would add that this saving and supplementing can well be done by mixing the manure daily, when taken from the stable, with a mixture of acid phosphate and kainit in equal parts. It has long been the practice with some to use plaster for this purpose, but while plaster, if properly used, is Some STATION INVESTIGATIONS IN FERTILIZERS—293 effectual in preventing the loss of nitrogen, it fails to add the potash and phos- phoric acid needed, and the above mixture will be as effective in preventing loss of nitrogen, and will at the same time add what the manure is deficient in. The Rhode Island Station has done perhaps more in the investigation of the value and effects of lime than any other of our Stations, and we add here, as an addition to what we have already said upon the effects of lime, the fol- lowing quotation from Bulletin 46 of that Station: CHEMICAL ACTION OF LIME. “Time unites with acid substances in the soil, by which the soil is sweet- ened, or its natural acidity (sourness) overcome or reduced. In case certain injurious iron compounds are present in soils, these are so transformed by lime as to be rendered harmless. It also acts upon the potash compounds in the soil in such a way that the lime takes the place of the potash, setting the latter free for the use of plants. If lime is present in a soil to which ordinary commercial fertilizers, dissolved boneblack, dissolved bone, dissolved phosphate rock, or double superphosphate, have been added, it is probable that some of the soluble phosphoric acid will further combine with lime, in which condition it would be expected to be more readily available to plants than would have been the case had lime been absent, and a more favorable op- portunity been given for all the phosphoric acid not quickly utilized by the plants to combine with iron and aluminum oxids. BIO-CHEMICAL EFFECTS OF LIME. “The presence of lime in soils favors the decomposition of the organic matter which they contain, and in this process carbonic acid is produced, which in turn acts upon the ingredients of the soils in such a way as to render the natural plant food much more readily assimilable. It plays, likewise, an important part in facilitating the change of ammonia into nitric acid, or, in other words, in placing at the disposal of plants the stored up nitrogen of the soil, as well as that applied to or left in it, in the form of animal ma- nures, meat, blood, fish, plant roots, ete. “Clover, alfalfa, and certain other of the plants which have the power of drawing their nitrogen supply chiefly from the air within the soil, are unable to make a satisfactory growth and to thus utilize the vast amount of nitrogen about them, provided the soil exceeds a certain degree of acidity, but by the application of lime they are made to thrive and to gather for the farmer stores of nitrogen, for which he must pay a fertilizer dealer, at present prices, at the rate of about thirteen cents per pound.” 294—Crop GROWING AND CROP FEEDING But it is unfortunate, perhaps, that the same effect the lime has in sweet- ening the soil for the bacteria that promotes the nitrogen collection of the legumes, will also sweeten it for the growth of other and injurious fungi, and hence it has been found that an application of lime to a soil well filled with decaying organic matter and planted in potatoes, will have the effect of pro- moting the growth of the fungus that causes potato scab. Hence it is well to avoid the direct application of lime to the potato crop. But if the lime is used to promote a previous growth of clover it will not injuriously affect the potatoes when planted on the clover sod. While most of the legumes are benefited in their growth by an application of lime, the Southern cow pea is an exception, and it seems to be injured rather than helped by the direct applica- tion of lime. But after a crop of peas has been grown on the land, the ap- plication of lime on the stubble will greatly aid in the work the peas do for the succeeding crop. Therefore, in a rotation of corn, winter grain, peas and cotton in the South the lime should always be applied on the small grain, especially if a large amount of organic matter has been applied to the pre- — ceding corn crop, either by the turning under of a winter crop or the appli- cation of the barnyard manures, or both. Quoting further from the same bulletin of the Rhode Island Station: “Lime applied to stiff clays causes them to become more friable, more perme- able to the air, easier of tillage and better capable of supplying water to plants as needed. Sandy soils, on the other hand, are rendered by it more compact and more retentive of water and fertilizers. On very dry, sandy soils smaller applications of lime must be made than upon moist ones, and the use of large quantities of lime upon such soils, in single applications is inadvisable. WHEN TO APPLY LIME. “For the reason that lime, while in its caustic state, is Injurious to cer- tain crops, and by lying in the soil its causticity is soon lost or materially de- creased, it is evident that the ideal time to apply it would be in the autumn. When autumn seeding is practiced, either with grass alone or in connection with winter grain, the lime should be sown upon the furrows after plowing, and then most thoroughly harrowed in, for the degree of benefit from liming will depend to a great extent upon its even distribution and complete incor- poration into the surface soil. Where seeding Indian corn fields to grass at the last hoeing is practiced, as is common in the Connecticut Valley in Mass- achusetts, it would be advisable to apply the lime in the manner outlined above after plowing the land in the spring for the Indian corn crop. Under other circumstances it is probably better not to lime just before Indian corn 5 SOME STATION INVESTIGATIONS IN FERTILIZERS—295 or rye, for these crops are liable to be slightly injured by fresh applications of lime, some of which is in a caustic state. [We would remark that we have never found this the case, and have used lime freely just before planting corn with the best effects —W. F. M.| “These statements, in relation to care in liming just prior to growing rye, Indian corn and millet, apply to cases where the nitrogen supply is chiefly in the form of nitrates, such, for example, as nitrate of soda, and where the soil conditions naturally induce rapid nitrification of the soil-nitro- gen, or of the nitrogen applied in natural and artificial manures, such as ammonium salts or organic matter. If the soil is very sour and ni- trates are not employed, then the use of lime immediately before these crops may prove of great service, for the reason that the benefit derived from the lime by virtue of its facilitating the transformation of the nitrogen into a form immediately assimilable by the plant, may far outweigh any direct in- jury that the lime might otherwise have exerted.” And we would add that ~ no good farmer will be so ignorant as to buy nitrates for his corn in a properly devised rotation, and no harm can come from applying lime to a soil where manure has been plowed under for the corn. IMPROVEMENT OF WORN LANDS. We find the following in Bulletin 62 of the Louisiana Station. How can the worn lands of Louisiana be most speedily and economically restored to their primitive fertility? The answer would be, by proper rotation of crops, with or without fertilizers. What crops shall be taken for this rota- tion? Any combination which omits our cow pea would be injudicious. Several years ago this rotation was decided upon as the best one attainable in this section: Corn, oats, followed by cow peas and cotton. This rotation is faulty in principle but correct in practice, and was adopted last season after two years’ trial. The corn should precede the cotton, but experience has demonstrated that Rust Proof oats, the only variety successfully grown here, must be planted in October if maximum results are desired. [In North Carolina they should be sown in September.] Cotton cannot be removed in time for this crop, while corn can; hence this metathesis of crops. This rotation was adopted with and without fertilizers. It was begun in 1889. Three parallel strips, one-half acre wide and two acres long, were selected for the experiments. The eastern half of each was manured regularly with a fertilizer adapted to the crop, while the western half remains without fertil- izer. The oats in the foregoing fertilized plat were fertilized with the Sta- tion’s grain fertilizer at rate of 200 pounds of cotton seed meal 296—Crop GROWING AND Crop FEEDING and 100 pounds of acid phosphate, mixed and scattered and harrowed in with the oats. The peas, fertilized with 50 pounds of acid phosphate and 50 pounds of kainit. The pea, being a nitrogen gatherer, no nitrogen was applied additionally. The cotton was fertilized with the Station’s compost for cotton, consisting of: One ton of acid phosphate; 100 bushels of stable manure; 100 bushels of green cotton seed; built in the following proportions: First layer, 5 bushels of stable manure ; second layer, 5 bushels of cotton seed ; ihird layer, 100 pounds of acid phosphate, etc. The cotton seed is made perfectly wet before spreading. The corn received the compost for corn, the ingredients the same as above, the proportion only being different, being one ton acid phosphate; 200 bushels of stable manure; 200 bushels of cotton seed, built as above, except proportion of 50 pounds of acid phosphate, 5 bushels of manure, and 5 bushels of seed. The cultivation of the above plats, for this year, was as follows: For corn, plat A, land was broken with three- mule disc plow, 8 inches deep in February. Rows marked off four feet apart and compost applied in the furrows at rate of 30 bushels per acre. A flat list was made on this and corn planted March 31st. At last cultivation peas at rate of two bushels per acre were sown broadcast. For oats followed by peas, the land was deeply plowed in October and the fertilizer named was scattered, and two and a half bushels of oats per acre harrowed in with it. After the oats were harvested peas were planted in rows, one bushel per acre, with the fertilizer named. For cotton the pea stubble was plowed in Febru- ary and manured with compost. A careful study of the results of this rota- tion experiment will convince the most skeptical farmer of the wisdom of the system. The fertilized half has been built up 400 to 500 per cent. in eleven years, while that without fertilizer has gained twelve to twenty-five per cent. It should be the aim of every farmer to so handle his land as to make it grow richer instead of poorer. By this system it can be done, and at the same time getting better crops and profits. It is of special interest to note that the plat on which no fertilizers were used, in 1889 made seven and a half bushels of oats per acre, and 4.22 tons of green pea vines; the second year after, when it came again in oats, made 25.5 bushels oats, 816 pounds of straw, 24 tons of pea vines, the increase being simply due to the rotation and the peas. An examination of the results will show the immense advantages to be derived from the moderate use of the proper fertilizers in the rotation. Incidentally it may be observed that each bushel of corn will give about 70 pounds of stover, which, when cured, is a most excellent forage for cattle, sheep and horses. The report would have been far more valuable and exact if the result from the use of fertilizers on each plat had been given as com- pared with the corresponding unfertilized plat and the cost of the gain com- SoME STATION INVESTIGATIONS LN FERTILIZERS—297%7 pared. The only statement given is that in one very dry season when the fertilized plat made over ten bushels per acre the unfertilized plat did not make even a nubbin. But we are not informed whether the ten bushels on the fertilized plat paid the expenses. If it accorded with the experience of the writer it did not. While there is certainly shown a gratifying increase in the crops on the land, and the rotation is the same that this writer has been advocating for the cotton growers of the South for many years, it would be interesting to have such a course of fertilization for every crop grown compared with the same rotation in which no fertilizer is used except a liberal application of mineral fertilizers to the pea crop following the oats, and all the home-made manures and cotton seed are applied broadcast to the corn field. From our own experience and that of some others whom we have in- duced to try the plan we feel sure that in the financial profit, if not in the ag- gregate results, this last plan would make a far better showing than the fer- tilization of every crop in the rotation. The bulletin does not give any infor- mation in regard to the use made of the pea vines. If simply used as manure direct, there was a serious loss as compared with the feeding and returning to the soil of the resulting manure. What the Southern farmer needs to learn more than the mere use of commercial fertilizers is that there is a profit to him and a larger profit to his farm, through the feeding of all forage grown on it. There will be a greater and more valuable accumulation of humus in the soil through the feeding of the peas and corn stover than in any other way in which they can be used, as the resulting manure from the straw, peas and corn stover of two fields would be added to one of them to go into corn. Another fault in the rotation is that there is nothing to come in between the cotton and the corn, and our Southern soil especially needs a green winter cover as a nitrogen trap; even rye will do better than nothing, and will at least add more to the humus accumulation on the corn field. With this modi- fication and the use of a larger application of phosphoric acid and potash to the pea crop, and no further fertilization with purchased plant food, this three year rotation will do more for the building’ up of the Southern soil and the prosperity of the Southern farmer than any course we can devise. CHAPTER XLI. FRAUDS IN FERTILIZERS. - There are in the manufacture of fertilizers today, men who are as hon- orable and correct in all their dealings as those in any other line of business, but in States where the fertilizer laws are not as strict, or are not as strictly enforced, as they should be, there are those in the fertilizer business (as in every other line of human effort), whose object is to live by their wits, and to give as little as possible for the money they receive. If the law and the in- spectors do not watch for him, the farmer is perfectly helpless to discover these frauds. If the stuff has a rank smell he is apt to conclude that it is a good article, when it may not be worth hauling home. Owing to the increas- ing stringency of the fertilizer laws, there is less of fraud in fertilizers than formerly, but the rogues are still about, and the farmer should take care in the purchase of fertilizers to deal with men of established reputation in busi- ness affairs. It is far better to pay what may seem a high price for an article of proved merit than to get a mixture at an apparently low price in which you will pay a high price for all that is valuable in it and then have to freight a lot of utterly worthless stuff put in to make weight and to make the price look low. There is hardly a manufacturer who will not make for customers any particular description of fertilizer mixture, and in many cases it may be better to get the mixture made according to your formula than to make it yourself. But it is not of the honorable fertilizer manufacturer we would speak now. It is of the rogues and their dodges. THE MAN WITH A SECRET. One of the most common frauds is the man who has a fertilizer formula for sale. We struck one of these fellows recently, in North Carolina. A cor- respondent wrote to us that there was a man in his section selling a formula and farm rights for $3.00, and he sent me the secret, asking my opinion in regard to it. The whole thing was a mixture of a few well known chemicals used in mixing fertilizers. These were to be mixed with a certain quantity (298) FRAUDS IN FERTILIZERS—299 of stable manure, and lime and woods earth, and the resulting mixture was claimed to be equal to any fertilizer sold and the cost was to be but $4 per ton. I explained to my correspondent the result of mixing sulphate of ammonia, and stable manure with lime, and published the fraud in one of the State papers. The editor soon got a letter from the “professor” enclosing one of his circulars and saying that I had attacked him and he wanted space for an answer. Since I had simply shown up the article he was selling and knew nothing of the man, the editor did not notice his request, but sent me the circular. In this he states that a certain noted chemist (himself) had made a wonderful discovery, which had astonished the scientific world, and that the process would put millions in the farmers’ pockets, when, in fact, the self styled professor had never been heard of as a chemist, and the scientific world had never been astonished at his mixture. But this fellow doubtless sold hun- dreds of dollars’ worth of his recipes to men who could not afford to take a paper, and who did not get the Station bulletins, and did not know that the Stations are always ready to furnish practicable formulas for fertilizers with- out charge. These compost peddlers seem to have found a rich field in the South, for the same thing was tried here several years ago, and the North Carolina Experiment Station at that time issued a bulletin of warning to the farmers. But the men who bought “farm rights” from the last man had not, of course, read that bulletin. “NATURAL PLANT FOOD.” Some years ago we received a circular from another correspondent,,giv- ing an account of another wonderful discovery, which was the natural food of plants. The circular gave the following analysis of this wonderful article. It was evidently gotten up for the purpose of bewildering the farmer, and I wrote to my correspondent that the article was simply pulverized phosphate rock and green sand marl, as was evident from the analysis. It read as follows: Per cent. Phosphoric acid. Total (P205)............. 21.60 to 29.49 Equivalent to bone phosphate of lime......... 27.20 to 64.38 Potash, (K20) from glauconite............. 1.00 to 2.00 {quivalent to common sulfate of potash...... 2.00 to 4.00 miigiervadd (S102) ey. tyne k ae 5.26 to 8.10 Carbone acid?

The cireular stated all these things were available to plants in the soil. The mixture was sold all the way from $20 to $28 per ton, according to locality. The New York Station took up the examination of the article in a bulletin, and showed that it contained in a ton but 28 pounds of available phosphoric acid and 2.6 to 4.5 pounds of potash, and at trade values for these, a ton of the great natural plant food was worth $1.52. This fraud, which was simply, as was evident from the analysis, a pul- verized phosphate rock and green sand marl (glauconite) has been so fully exposed that nothing has of late been heard of it. All that a farmer needs to know in regard to any fertilizer mixture is how much nitrogen, phosphoric acid (in an available form) and potash it con- tains. That a certain percentage of phosphoric acid is equivalent to what would be contained in another combination, such as bone phosphate of lime, has nothing to do with the matter, and is only put there to make the farmer think there are bones in it; as these fellows know that most farmers have a high - opinion of the value of bones, though they know that the article has no bone in it whatever. They also know that farmers consider sulphate of potash the best form, and hence they say that the percentage of potash in their stuff is the same amount that would be found in a certain amount of sulphate of pot- ash, while there is not a particle of sulphate in the stuff. .5o far has this habit of putting “equivalent to,” on the sacks obtained, that firms that should know and do better sometimes add these meaningless figures. I have before me a sample of “Pure Raw Bone.” he analysis printed on it says: “Ammonia, 3.65 to 4.15 per cent.; phosphoric acid, 22.00 to 24 per cent., equivalent to bone phosphate of lime, 48.00 to 52.00 per cent.” This simply means that the article contains about 3 per cent. of nitrogen and 22 per cent. of insoluble phosphoric acid. Fertilizer manufacturers have always put the nitrogen content on their sacks in the form of ammonia, because as they say, “the farmers understand ammonia but not nitrogen.” How it is easier for a farmer to understand a combination than a simple ele- ment we cannot understand. The figures are put there simply because they look larger in the form of ammonia, a compound of nitrogen and hydrogen, than they would if only the actual nitrogen was printed. The 3.65 per cent. of ammonia is simply 3 per cent. nitrogen but it looks larger to put on the combination figures, and so the practice has grown. The above analysis does not show a very high grade of raw bone meal, and the sliding scale is deceptive also, as it gives the FRAUDS IN FERTILIZERS—301 dealer a loophole to crawl out of. The law in North Carolina does not allow a manufacturer to say 3.65 to 4.15 per cent. He must give the lowest percentage he claims and no more, and this law also requires that noth- ing be printed on the sacks except the percentages of nitrogen, available phos- phoric acid and potash. Only this and nothing more, unless, as is proposed, the source from which the constituents are derived be added. In some of the States no value is allowed for insoluble phosphoric acid, while in others it is valued at 2 cents per pound. In regard to this we quote from Dr. Roberts’s book on the “Fertility of Land.” He gives a table show- ing that “the average of forty-nine soil analyses shows that more than 4,000 pounds per acre of phosphoric acid are contained in the first eight inches of surface soil, the larger part of which, presumably, is insoluble under pres- ent methods of tillage. Would it be wise or profitable to purchase, at 2 cents per pound, additional insoluble phosphoric acid, when the soil contains such vast stores of this low grade plant food? ‘True, a part of the so-called insolu- ble phosphoric acid may become available and produce beneficial results, but since the soil is usually abundantly supplied with the same kind of material, would it not be wiser to make it available by tillage than to purchase more of this lazy plant food ?” We quote the above largely because there has been special effort to put insoluble phosphoric acid on the market in the form of “floats,” or pulverized phosphatic rock, and the soft phosphates of Florida, which are not adapted to the making of acid phosphate. There is abundant evidence, however, that on some soils these insoluble forms of phosphoric acid do produce good results, though seldom on the immediate crop. If offered at a reasonably low price there is nothing fraudulent in the selling of these articles to the farmer, pro- vided a fair price is charged for the same. It would be noted that the value to the farmer of insoluble phosphoric acid depends largely in the material that carries it. In ground raw bones, the phosphoric acid is in an insoluble form, but the material decays rapidly in the soil, when finely ground, and the acid becomes available more quickly than that in the rock phosphate, but the chances are the farmer will have to pay more for it than if he could buy solu- ble phosphoric acid in a superphosphate. . As we have before remarked, the frauds in fertilizers are becoming fewer annually, as the laws of the different States become more stringent and are more strictly enforced. In the Cotton States, where fertilizers have long been sold in immense quantities, the laws are better than in those States where the use of these has but recently begun, and there should be some united effort on the part of those in control of the fertilizer inspection in the various States » to get uniformly good laws and to enforce them. These laws are as much 302—Crop GROWING AND Crop FEEDING for the benefit of the honest manufacturer as the farmer, for he has to con- tend with an unfair competition. Recently the peddlers of secret formulas for fertilizer mixtures have been very active in the South, where the farmers buy fertilizers largely, and, by extravagant tales of what their fertilizers will do and the cheapness of the mixtures, they have been able to sell a good many of their recipes to those who think they cannot afford to take a paper, and who never think of calling on their Experiment Station for the proper formula, which they could get free of charge. One of the most recent circulars issued by these humbugs and sold to farmers reads as follows: HOME FERTILIZERS. Recipe price, $5.00. The greatest fertilizer known for the farmer. Results much better from using the home fertilizer than any other made. Cost, $3.00 per ton. Box to hold one ton four feet square. INGREDIENTS. No. 1. Stable manure one inch thick. No. 2. Chemicals one gallon on layer. No. 3. Lime one-eighth of an inch thick. No. 4. New dirt one inch thick. No. 5. Ashes one-half inch thick. No. 6. Salt 60 pounds per ton. CHEMICALS FOR ONE TON. Potash, 8 pounds: nitrate of soda, 4 pounds. coperas, 4 pounds, muriate of ammonia, 12 pounds, phosphate acid, 5 pounds Mix with 12 gallons of warm water The name of the concocter of this mixture is not given, but at the bot- tom is written “John Green, Agent, from Sullivan Co. Tenn.” Now as to the ingredients of the mixture. Muriate of ammonia is never used for fer- tilizing purposes, for the nitrogen in it can be had far more cheaply in other forms. The chemicals are to be mixed with warm water. This would make the ammonia be set free by the potash, and be lost. Copperas (which the ignoramus spells “coperas”) is the sulphate of iron and of no use as a fertil- izer. Nitrate of soda is, of course, valuable, but it, too, would be lost in the mixture, and if not, the amount of it in the ton would, as one chemist has said, be about equal to three dead cats per acre. Commercial potash is not used as a fertilizer ingredient, since its caustic properties would set ammonia free, and the lime would not only have this effect but would revert the little FRAUDS IN FERTILIZERS—303 phosphoric acid in the mixture. The salt is of no value whatever as a fertil- izer, and the ashes would have the effect of releasing the ammonia in the sta- ble manure, with only the “new dirt” to catch it. One ton of this mixture would contain about 7 pounds of phosphoric acid. 6 pounds of nitrogen (if it did not get away) and 22 pounds of potash. As an average commercial fertilizer contains about 170 pounds of available phosphoric acid, 50 pounds of nitrogen and 45 pounds of potash, the bulletin of the North Carolina Sta- tion, from which we get these facts, well remarks that it would take over two tons of the home fertilizer to furnish the potash in one ton of the average commercial fertilzer, over eight tons to furnish the nitrogen and over twenty- four tons to furnish the phosphoric acid. Those who read this, or the bulle- tin of the North Carolina Station, will hardly be swindled out of their $5 bills. The same bulletin, No. 173, of the North Carolina Experiment Station, of the College of Agriculture and Mechanic Arts, gives the following won- derful circular, the original of which is embellished with a portrait of “Col. I. J. Britain, Inventor, Winston, N. C.,” and is as follows: “THE PROCESS OF COMPOUNDING THE FARMERS COMPOUND FERTILIZER. “First dig a stable pit size of stall or stable three feet deep. After dig- ging the pit take a rich loamy soil, or swamp muck. After being good and dry place in the pit to the depth of six inches, then place a thin layer of tobacco stalks, rotten straw or cotton seed. Then apply liberally by hand over the entire surface of the pit, the following compound or mixture: “T'wenty-five pounds saltpetre, one bushel of common salt and one quart of carbolic acid, one gallon on each layer of the rich soil. Then dilute the carbolic acid in ten times the amount of water, and sprinkle each layer. Then fill in another layer of rich soil and straw, and apply another sprinkle of the compound, and continue as above stated six inches of loam and another sprinkle of compound until the pit is filled to the surface of the ground. Then floor the stall or stable by laying small poles on the compound and floor the stable. The stock should be kept in the stall six months. The’ drainage of the stock and stall adds a great deal to the compound. This is the single process of compounding the Farmers Compound Fertilizer. “Then construct alongside of stables a pen or pens with water tight floor, slanting downward. Place a V trough by the side of pens to catch the con- 304—CroPp GROWING AND Crop FEEDING tents of said pen and run off in a barrel. Fill the pens with barnyard, chip manure, tobacco stalks or any rubbish, leave the pens uncovered. Construct by trough, the water from eaves of barn or stables into the pens. Care should be taken not to let too much water go into the pens. Thus you have a com- plete leaching system. When the barrels are filled with lye from the pens it should be poured in stall or stable and sink into the pit with the com- pound. This is the double process of manufacturing the Farmers Com- pound Fertilizer. STOCK IN THE STALL IS A GOOD CONDUCTOR OF amonia from the air. Established by which the amonia phosphoric acid and Potash from the solid manure, is conducted into the pit under the stall or stables and is there joined by the same ingredients in a safer and more abund- ant form, from the liquid manure deposited by the stock: making a powerful and available plant food in a much more concentrated and availible form than is found in high priced commercial fertilizers. At the end of six months your pits are ready to throw out, the contents of which has by this time be- come out as black as ink and as strong as lye. If you now want to use this through a drill it will be necessary to dry by spreading thinly on barn lot or floor and run through a sieve, or what is better, if you have one, an old fan- ning mill. If you wish to use in the drill on any crop when a drill is not nec- essary the drying sieving may be dispensed with. An ordinary stable, say 10x14 feet will furnish 200 bushels of the compound sufficient to fertilize 20,000 hills of tobacco or twenty acres of wheat with the highest grade fer- tilizer known to science. The public is warned not to infringe upon my in- vention unless they are authorized by myself or lawful agents, for my rights must be respected. Copyright secured. I. J. BRITAIN, WINSTON, N. C.” We have copied this singular circular in full, spelling, punctuation and all, to show with what sort of stuff some men try to fool farmers The bulletin well says that the prominent statement that “stock in the stall is a good con- ductor of amonia from the air” is not true. Neither is the statement that the result of all this waste of time and labor is a powerful and available plant food in a much more concentrated form than is found in high priced fertil- izers, true. Still further from the truth is the statement that the mixture is “the highest grade fertilizer known to science,” for it is nothing of the sort. Inquiry of the Librarian of Congress reveals the fact that their indexes do not FRAUDS IN FERTILIZERS—305 show any entry of a copyright for the process of compounding the Farmers’ Compound Fertilizer by I. J. Britain. The directions are a jumble which no one can follow. He uses 25 pounds of saltpetre. or nitrate of potash The nitrogen and potash can be had in far cheaper forms. The bushel of common salt is of no use whatever. Carbolic acid is used, and this is of no value as plant food, and, in fact, would be a preservative from decay and a hindrance to germination. But the whole process is so absurd and wasteful of time and labor that it would seem it is only needed to state it to see this. But many simple minded folks are annually caught by just such pretenders, and our lists of humbugs would hardly be complete without this one, which flourishes close to the home of the author. The way to deal with all these secret process fellows is to report them at once to your Experiment Station, and their secret will be gotten, and pub- lished and shown up in its true colors. There is not a Station in any of the States that will not furnish, free of charge, correct formulas for the mixing of concentrated fertilizers to the farmers of the State on application. As we have said, it is the men who do not read and do not take the agricultural papers who get caught with these baits, and pay far more than the correct information to be gained by reading would cost them. CHAPTER XLII. THE STRAWBERRY AS A FIELD CROP. The great extension southward of the culture of the strawberry as a mar- ket crop has made its proper fertilization a matter of great importance to the growers. ‘There is now a regular succession of the strawberry, from the earli- est that come from Florida to the latest that reach the great cities of the North from points north of their latitude. At the distant points the growers ure, of course, entirely dependent upon commercial fertilizers for the produc- tion of the crop, and they have found that the strawberry needs liberal feed- ing. Fortunately the soils on which the strawberry thrives best are also the soils on which commercial fertilizers have their best effect. Low, flat lands, where the permanent moisture is not far below the surface, and where the soil is well filled with humus, are always the best soils for the strawberry, and even where they seem less fertile than the dry uplands they will produce better crops of strawberries simply by reason of the presence of moisture al- ways in reach. Not that strawberry lands should not be well drained, but that the soil should have the water table not too far down, so that capillary moisture can always be depended upon. MANURIAL REQUIREMENTS OF THE STRAWBERRY. As in most fruits and vegetables potash plays an important part in the production of the fruit of the strawberry, while phosphoric acid is the con- trolling factor in the growth of the plants and the maturity and firmness of the fruit. While a due percentage of nitrogen is needed for a luxuriant growth, an excess of this element will be apt to cause the fruit to be soft, and to carry badly. We can see, therefore, that the crop demands a well propor- tioned complete fertilizer in which, with a due percentage of nitrogen there (306) THE STRAWBERRY AS A FIELD Crop—307 will be an abundant supply of phosphoric acid and potash. As the plant analysis shows the need of the plant for potash, and the soils in which the market culture of the strawberry, in the South especially, are deficient in this constituent, the percentage and form of the potash becomes an important matter to the strawberry grower. While nitrogen is an important element, we are of the opinion that the growing of a crop of cow peas the summer be- fore planting the strawberries will usually supply a sufficient amount of ni- trogen for the first growth of the plants, and that subsequent growth can be maintained by top dressings of nitrate of soda. The growing of the peas will not only supply nitrogen forming organic matter, but will make a profita- ble forage crop to precede the strawberries, and a large part of the phosphoric acid and potash needed by the strawberries, can be advantageously applied to the pea crop to encourage its growth, and to enable the plant to do the great- est possible amount of nitrogen catching for the strawberries. The common practice of the strawberry growers in the South is to set the plants in August cr September, and to heavily fertilize the ground so as to get a fair crop of fruit the following spring. In the spring, as growth begins, a top dress- ing of nitrate of soda is added. The plants are allowed to mat along the rows, and to bear a crop the following year, after which they are plowed under. In this system a field is planted every year, so as to have always one to turn under after the crop is off. But owing to the fact that there is apt to be long continued dry weather at the time usually selected for planting, many growers are making a practice of setting later in the fall, even in November and De- cember whenever the ground is not actually frozen. In the North, there is no doubt we believe that spring is the best time to set the plants, but here our finest success has been from November setting. We once set a patch of straw- berries in November and cold weather set in at once, but no harm was done, and much to my surprise the plants set a very good crop of fruit in the spring, and were so well grown that we allowed it to ripen. If we were at all certain of seasonable weather in September, we would prefer that month for the set- ting to any other, but we are usually compelled by reason of the drought to be later in setting. Fertilizer formula for the strawberry: Acid phosphate, 900 pounds; cotton seed meal, 700 pounds; nitrate of soda, 200 pounds; sulphate of potash, 200 pounds. Of this the best growers would use not less than 1,000 pounds per acre, on land where no previous crop of peas has been grown. Where a growth of dead pea vines has been plowed under, the amount of organic nitrogen in the shape of cotton seed meal can be dispensed with; and the ni- trate of soda should be reserved for the spring dressing where the plants are set late in the fall. 308—Crop GROWING AND Crop FEEDING FORCING THE STRAWBERRY. There is no fruit so easily and profitably forced under glass in winter as the strawberry. But let no inexperienced person suppose that a strawberry plant can be taken up in the fall, placed under glass and given a forcing temperature and succeed. For the purpose of forcing, the plants need to be grown for months previous, and properly handled so as to make strong crowns that will bloom and fruit well. We always force strawberries in six-inch flower pots. We begin with the first rooted runners in early sum- mer. As soon as these have started to form white roots an inch long we take them up and set them in three-inch pots, in the ordinary compost of rotted sods and manure which we use for general greenhouse potting. The plants are set in a frame on a bed of coal ashes to prevent the earth worms from get- ting in, and are shaded with lath screens in place of sashes, thus giving them a varying shade and sunlight; and special attention is given to the supplying of the plants with water. As soon as the roots have matted around the balls of earth in these pots, they are transferred to the 4-inch size, replaced in the frame and treated as before. Then, as soon as the 4-inch pots are well filled with roots, they are again repotted into six-inch pots in which they will be fruited. These pots are now plunged to the rim in the coal ashes and at- tended to carefully. As the pots get well filled with roots some liquid ma- manure is applied, once a week, to encourage a luxuriant growth and to aid in the formation of strong crowns, for no weak plant can be successfully forced. As cold weather approaches less water is given, the plants are allowed to be- come semi-dormant, and are allowed to be exposed to the frost for a while, since the forcing must be preceded by a short period of rest. The first plants are put in the houses in December. All the old leaves are trimmed off, the plants well watered and started in growth with a night temperature of about 45 degrees, and kept moderately cool in day time. As they begin a new growth we give, once a week, a watering with a solution of an ounce of nitrate of soda to four gallons of water, taking care to apply it only when the plants are moist at the root and not when needing water, and to pour it on the soil end not over the foliage. See that the drainage of the pots is right so that the abundant watering that is needed will not sour the soil. The side bench of the house near the glass is the best position for the plants. As the blossoms appear it is well to brush them over daily at noon with a camel’s hair brush, {o insure fertilization; and no variety should be forced unless it has perfect flowers, and it is naturally an early bloomer in the open ground. Flowers of sulphur dusted on the hot water pipes is valuable for keeping down fungus troubles. Do not pack the pots so closely as to touch each other, but have a THE STRAWBERRY AS A FIELD Crop—309 space of two inches around every pot. Carefully avoid watering overhead, on the whole plant, when blooming, but always apply water by pouring it under the leaves. When well grown, and the variety is a good one, the crop should be a profitable one. They are sold in paper boxes holding half a pint. We have found, as with the tomato, that bone dust added to the soil is better than stable manure, though the ordinary potting compost, if old and well rotted, answers very well. If earth worms get into the pots they will paste the soil together and cause it to sour. If there is evidence of their presence pour a little lime water on the pot to draw them out, and at the same time sweeten the soil. The plants that have been forced in winter can be planted in the open ground in the spring and will make a late crop there as they get into growth. During their growth in preparation during summer, and in the house in winter, it is needless to add that no runners should be allowed to grow; and the keeping of them off will be one of the chief attentions needed in the preparation of the plants, aside from keeping the pots watered and free from weeds. CHAPTER XIIII. | BLACKBERRIES AND RASPBERRIES. The requirements of these are so similar that we treat them together. Both are fond of a comparatively heavy loam, but are not very particular as to soil, provided it is in a fertile condition and well supplied with humus. Plants of the red raspberry and the blackberry should always be grown from root cuttings, as such plants are far better than those from the suckers around the old plants. The black caps are grown from tips of the canes, which should be buried along the rows after the growth of the season is about ma- ture. The running blackberry (or dewberry) can be grown in the same man- ner. We set the plants in rows six feet apart and three feet in the rows, and train to stakes, or to a single wire stretched from the stakes about four feet from the ground. Dewberries should be allowed to trail along on the ground along the rows the first season, and should not be tied up until the spring they are to fruit. The best way to train them is to set forked stakes about two feet from the ground, and lay slender poles like hoop poles from stake to stake to which to tie the vines. These poles are better than wires, as the wire is apt to chafe and cut the canes. After the fruit is gathered, cut away the old canes and train out as many new ones from each stool as are sufficient, and train them along the rows out of the way of cultivation and injury. MANURIAL NEEDS OF BLACK AND RASPBERRIES. If the growing of peas or clover previous to the strawberry crop is desira- ble, it is far more so with the blackberry and the raspberry, and success will not be certain with these unless the soil is kept well supplied with organic matter. As they will keep the ground longer than the strawberry this is one of the points to look after during their growth. We have found it a great advantage to plant a single row of cow peas between the rows of blackberries, after the fruiting season is over, and to cultivate them as long as it is practi- cable, letting the whole growth die on the land to be plowed under in the (310) BLACKBERRIES AND RASPBERRIES—311 spring. Treated in this way there will be no need for the application of nitrogenous fertilizers, but a fair supply of the mineral elements should be given annually, making the mixture about 4 parts of acid phosphate to one of sulphate of potash. Allow no more canes to grow in the hill than can have room for full development, and shorten them back annually, or, what is better, pinch in summer to induce the growth of side shoots and to make bushy canes. PROPAGATING THE PLANTS. Many growers depend on the suckers from the base of the blackberry and red raspberry plants for planting. But it will be found that far better plants can be grown from cuttings of the roots made in the fall. We make these cuttings about three inches long, mix them in moist sand in boxes. and bury the boxes outdoors during the winter, with a mound of carth over them to prevent access of water. They remain there till early spring and are then planted in the open ground in rows wide enough for horse cultivation, and dropped about four inches in the rows. These root cuttings make a strong growth during the summer, and are far better plants than those cut from the old plants as suckers. With new and rare varieties that are high priced we have adopted another and more rapid way. Years ago when there was a furor over the Herstine raspberry a friend bought two large plants for which he paid $5. He received them late in the fall and asked me how he had better treat them. I told him that if he would give me the plants I would propagate them and give him one-half the plants I made, as I thought I could put him just as far ahead in the spring as with the plants he had. He brought me the plants, which were very fine ones, with long roots. These were cut into pieces about an inch long, placed thickly in shallow boxes of light soil, and covered half an inch. The boxes were then placed on the propagating bench in the greenhouse, where there was a good bottom heat. There they started rapidly and as soon as leaves developed were set in two and a half inch pots, with the ordinary potting compost, and placed in a cool greenhouse, and a lit- tle later were shifted into three-inch pots. By the time frost was over in the spring I had 250 strong plants with tops a foot or more high, and these, planted in the open ground, each, during the summer, made a plant as strong as we would have had from the original plant had it been set, and we had 250 plants instead of two for the $5. Of course, with raspberry plants at the usual price per thousand it would hardly pay to adopt this method, but with plants selling at fancy prices it will enable the grower to get a stock in advance of the lower rates. Blackberries are propagated from root cuttings in the same way as red raspberries. 312—Crore GROWING AND Crop FEEDING Blackeap raspberries are grown from the tips of the canes, which are covered with soil in summer and by fall have formed a strong plant, which can be then separated from the cane. Some of the blackberry family, such as the dewberry, are also grown from the tips. Raspberries are far more diffi- cult to grow in the South than they are in the North, and require for their best suecess a moist soil and partial shade during the heat of the day. The blackcaps are far more certain croppers in the South than the red raspberries, but the red varieties can be grown if attention is paid to the summer pinching of the canes to induce a bushy growth, for if long canes are exposed to the sun they will certainly be killed. The Michigan Experiment Station has published a descriptive catalogue of over 400 varieties of raspberries, which those interested can get for con- sultation. . CHAPTER XLIV. FERTILIZERS IN THE VINEYARD AND ORCHARD. After years of patient experiment in the growing of grapes with commer- cial fertilizers on a soil nearly pure sand, we think that we have learned some- thing in regard to the food necessities of the vine. The soil of the sand hills of Southern North Carolina was selected for the series of experiments car- ried on to determine the food requirements of various fruits and tobacco for . the very reason that the soil was nearly a barren sand and had never been in cultivation, and hence was not altered by manuring. ‘These experiments were conducted by the North Carolina Agricultural Experiment Station through a series of years, and were managed with the most minute care to avoid any source of error. The land was cleared from the original pine forest, and every stump was dug up and hauled off the land, since the burning would have made changes in the food content of portions of the land, and this we aimed to avoid. The little humus that would naturally have collected in a forest had been regularly destroyed by the forest fires which annually ravaged that section. The forest growth was long leaf pine and scrub oak, and between these the land was covered with the tall growth of wire grass (Aristida Stricta), the great feeder of the fires. This sand hill region has been found peculiarly favorable as a winter home for people suffering from throat and lung diseases, and considerable settlements have grown up with hotels for the transient guests, and many homes of those who have found health there and have remained to make permanent homes. These residents made some experiments in fruit culture, at first only with grapes, and they found that with the aid of fertilizers the apparently barren sand grew grapes in wonderful profusion and of remarkably fine quality. Later on other fruits were attempted, and now the peach is the leading market fruit. The experiments were inaugurated for the purpose of studying the needs of the various fruits as to food, and to show the growers how most economically to grow the fruit. Of course the amounts applied on such a soil are no indi- cation of what should be applied on a different soil and in a different climate. (313) 314—Crop GROWING AND Crop FEEDING Still, the evidence is that trees and vines, like other plants, need a proper pro- portion of all the leading forms of plant food usually deficient in many soils. ‘The same question arises in the fertilzation of fruit trees and grape vines as with the annual crops. How shall we accomplish their feeding in the best and most economical manner, and what forms of plant food are most generally needed by orchard and vineyard products? We think that our ex- perience has taught us something in this regard. FEEDING THE APPLE ORCHARD. A study of the tables in the appendix to this book will show that in the leaves of the apple and the whole structure of the tree, the chief needs are nitrogen and potash, while in the fruit potash takes the lead, and phosphoric acid cuts a small figure. The complaint is general in most parts of the country, that apples do not grow as they formerly did. Men keep an apple ‘ orchard and make a hay field or a pasture of it, and expect the soil to continue to give them fruit while in every crop they are taking away from the soil the plant food the trees need. It is easy to convince farmers of the need for using fertilizers on their wheat, oats and corn crops, but most of them seem to im- agine that an apple tree does not need feeding, but can take care of itself like the trees of the forest. The great reason for the failure of apples where they once did well is the depletion of the soil of the mineral matters which the trees need. A crop of apples of fair proportions will remove more potash from the soil than three good crops of wheat. No farmer would be surprised that wheat finally fails to grow on land receiving no fertilizer, but the idea of ap- plying fertilizers to apple trees never seems to occur to them. ‘There are endless theories in regard to the proper method of planting, pruning and feed- ing apple trees. Some prominent authorities insist that deep plowing during the whole of the tree’s existence is essential to sueccess, and point to the old apple orchards in sod as examples of bad treatment. 'To some extent they are right, for the common method of keeping orchards in sod for the purpose of pasturage or mowing hay from them is certainly an evil practice. But there is a right way and a wrong way of keeping trees in sod, as we will endeavor to show. PLANTING AN APPLE ORCHARD. The most common mistake made at the start is in planting trees too old. Nurserymen commonly root-graft apples in winter, and set them in nursery rows in the spring. ‘The first season’s growth in the nursery is a tall, straight FERTILIZERS IN’: THE VINEYARD AND ORCHARD—315 stem with few or no branches. The man who wishes to do the best with his orchard will select these “maiden,” or one-year-old trees for setting. There are several advantages in this. The trees can be had for less money than the two or three year trees commonly planted. The planter can start the head of his trees uniformly, just where he wants to start it, and the young tree, not being crowded in a nursery row, can develop a head of proper proportions, and by the time it has reached the age at which most people want to plant from the nursery it is a far larger and better proportioned tree than the one left in the nursery row. The nurseryman heads back the trees in his rows the second year, but he does not head them down so low as they should be in the orchard ; and when we plant a two or three year old tree we generally have an ill shaped head started, and started where we do not want it. The result is that if we are to get the uniformity of head we want there must be a great deal harder pruning done at planting time, and the trees are never as symmet- vical as they would have been had they been planted as yearlings and properly started. Writers on fruit culture have various notions as to what should be the method used in starting a tree in the orchard. Many insist that the central siem should never be shortened, while others would head back as the nursery- men do, and form an open headed tree. We certainly prefer this plan. Five years ago we planted two apple trees of the same variety within 30 feet of each other. The trees were planted in a close sod and have never had any cultivation. They are in a soil of fair fertility and on a lawn near a dwelling. One tree at planting was headed back to the point where we wished the head to start; the other had the leading shoot left, and the side branches merely shortened. Both have been properly pruned to keep the head clear of becoming a tangle of shoots, and both have grown fairly well. But the tree headed back and formed into a round, open head has far outstripped the other, is now about twice the size and bearing apples. while the other has not reached this stage. The headed back tree has a trunk of not over 20 inches from the ground. The other has a trunk of four feet. The growth of the tree headed back has been rather phenomenal, and is fully as great as that of trees set at same time in the orchard and kept cultivated annually. But the lawn where it stands has merely been mown, and nothing has been re- moved from the soil. All the grass decays where it falls, and no manure of any kind has been given to either tree, but there will be some applied now that they are getting into bearing. It seems evident, however, that the decaying organic matter from the grass has furnished the trees all the nitrogen they needed, since all the organic matter produced has been returned to the soil,and they will need only light dressings of acid phosphate and plenty of petash. I 316—CropP GROWING AND CROP FEEDING said they had had no manure, but they have been twice limed, and this has, of course, helped in the nitrification of the organic matter, and in the release of potash from the clay soil in which they stand. Still, while it is evident that apple trees can be planted in sod and do well, we do not think that this one instance warrants us in recommending the general planting of apple trees in sod. What we want in the young tree for the first years of its life is vigorous growth, and as a rule this is promoted by good cultivation and manuring. But we do object to the advice given by & prominent writer on orcharding, to plow and cultivate the orchard deeply so as to force the roots down in the soil. We prefer to work all plants shal- lowly, so as to keep the roots in the best soil and in reach of the influences of the air and fertilizers, and not to force the roots of trees down into the unim- proved and unaerated subsoil. If the roots are forced down by deep cultiva- tion there must inevitably be a great loss of the fertilizing matters applied before the deep set roots can get the benefit of them. Prepare the soil deeply and well before planting and then cultivate shallowly, every summer till July, until the trees get into a bearing state, and then put the orchard in grass and treat it as you would a lawn, by frequent mowing and letting the cut grass lie to help the trees. In short, plant and grow an upple orchard for apples alone, and you will get them. STARTING THE TREES. Having selected one-year-old trees with a single stem, we prune all the roots that have become in any way bruised or broken in digging, and cut off all the fibrous roots, as they are commonly dried up. Make the holes no deeper than the plowing was done, for a deep hole in the hard subsoil will simply be a reservoir for the water to settle in and damage the roots. Put no manure of any kind around the roots of a young tree, but simply put the surface soil in the bottom and work it in among the roots, and then ram the earth as though you were setting a post. Never pour water in the holes to settle the earth, for the wet earth will crack and admit air in drying. A good ramming of moderately dry soil is all that is needed. In the North it is probable that spring planting will be best, but anywhere south of Pennsyl- vania we would, as a rule, set trees in the fall. Nurserymen advise planters to get the trees in the fall, even if they set them in the spring, and heel them in ready for planting; the recommendation is mainly for the convenience of the nurserymen, for we had rather plant than heel in. Having set the trees, the next thing is to head them back to the point where you wish the head to start. Low headed orchard trees are best in any locality, and south of the Potomac no orchard tree should have a stem of over FERTILIZERS IN THE VINEYARD AND ORCHARD—317 two feet, and we make ours about 20 inches. Farmers say they want the trees tall enough to get under in cultivating. The fact is that there is no need for getting under them, for if the cultivation reaches the outer branches it is sufficient ; for the feeding roots of a tree are all, as a rule, out where the drip falls and beyond, and there is the place where cultivation and manur- ing are needed. Therefore we head back the young tree to the height we want the stem. The low head protects the stem of the tree from the hot sun and the trees do not get blown over as tall stemmed ones are sure to be. When growth begins in the spring we select the three or four best situated buds that start near the top as the limbs of the future tree, and rub off all others; and allow no others to start during the summer but those we have selected for the main limbs. ‘These, at the next pruning in winter, are short- ened back to make them branch and gradually form a round and open headed tree, and care is afterwards taken that no sappy sprouts are allowed to grow in the centre of the tree. These are rubbed out as soon as they start, so as to throw the whole strength of the tree into the desirable form. An orchard started in this way will seldom need any pruning at all after it gets to a bear- ing size, except keeping out the water sprouts in the centre and around the base of the tree. We have given these methods of practice as a necessary preliminary for the feeding of the orchard. We have said that the feeding roots are out where the limbs reach. There is, then, little use for putting manure or fer- tilizers up against the stem of the tree after it has developed much top. In our experiments at Southern Pines, N. C., we proportioned the amount of fer- tilizer applied to the size of the tree, and did not apply it ail over the ground until the roots of the trees had occupied the land between the rows. We began by applying the fertilizer to a small circle around the tree, making the amount applied proportionate to the space occupied by the roots, and enlarged the circle every year as the roots extended. In ordinary orehard culture this minute care, is, of course, not needed, and as some crops are com- monly grown between the rows the whole soil should be fertilized at once. CULTIVATING AND CROPPING THE ORCHARD There can be no possible objection to the growing of vegetable crops in a young orchard to help in paying the expense of cultivation; but the com- mon practice of planting the orchard in corn is objectionable. Tall growing plants like Indian corn and the like, which occupy the land during the whole summer, are objectionable for more than one reason. The crowding prevents the proper development of the head of the tree, and the wide reaching roots rob the soil of too much moisture. Low growing crops that occupy the land 318—Crorp GROWING AND Crop FEEDING during the earlier part of the summer, like early Irish potatoes and other early garden crops, are far better, for all cultivation in the orchard should cease by the first of July; and then some soil cover crop like crimson clover should be sown, to keep a green cover on the land during the winter and to plow under for the furnishing of the organic matter that is to supply the trees with the needed nitrogen. It is a good plan to set a stout stake on each side of the tree a foot or more high in the line of cultivation, to prevent a careless plowman from striking the trees with the singletree. What we want in the trees is a good but not too rank and sappy a growth. Therefore, as 2 rule, we would avoid the use of stable manure and depend on the promotion of the growth of the legumes by liberal applications of phosphoric acid and potash, to furnish all the nitrogen needed. In fact this will, in a few years, be found a superabundance, and after the orchard is put in grass there will be no need for any nitrogenous application, but liberal applications of potash and phosphoric acid will be needed to replace the mineral matter carried away in the fruit. An orchard in a mown sod on which no animal is allowed to graze and from which no grass is taken away, will be longer lived, more healthy and fruitful than a cultivated orchard, if the mineral matters are kept sup- plied to the soil. The outcry against orchards in grass on the part of some writers has been caused by the old method (or lack of method) with orchards in grass. We wish to especially impress upon our readers that it is not this kind of grass-orcharding we advise, but the keeping of the orchard in grass purely for the benefit of the trees. The grass, mowed frequently during the growing season, will be constantly adding humus to the soil, and tending to promote rather than impair the moisture content. The fertility of the soil must be kept up by regular applications of phosphoric acid and potash, and if this is done the soil loses nothing but what is carried off m the fruit, and the fertilizers applied will more than make good this loss. Another advant- age in this method of keeping an orchard in grass is the fact that a soft cushion is formed under the trees, and the windfalls are not bruised. In fact, if the trees are headed as low as we advise there will be little trouble in gather- ing the greater part of the fruit without ladders. An annuai dressing of the following mixture will keep the grass in fine condition, and the dead grass itself will furnish organic matter, forming nitrogen sufficient for the trees. Acid phosphate, 1,600 pounds; muriate of potash, 400 pounds to make a ton. Of this use 400 pounds per acre annually in bearing vears at least. If at any time there should be evidence of lack of vigor in the trees, replace the acid phosphate with raw bone meal, which will furnish about 4 per cent. nitrogen. One caution about the distances for planting. Most of our apple trees will do better planted not less than 35 feet apart each way. Crowding FERTILIZERS IN THE VINBYARD AND ORCHARD—319 is a general fault with inexperienced planters. On very fertile soil even a wider distance will be better. ANALYSIS OF THE APPLE TREE AND ITS PRODUCTS. Apple leaves collected in May contain water, 72.36 per cent.; ash, 2.33 per cent. ; nitrogen, 0.74 per cent. ; phosphoric acid, 0.25 per cent., and potash, 0.25 per cent. Collected in September they contain water, 60.71 per cent. ; ash, 3.46 per cent.; nitrogen, 0.89 per cent.; phosphoric acid, 0.19 per cent., and potash, 0.39 per cent. The fruit of the apple contains 85.30 per cent. of water, 0.39 per cent. of ash, 0.13 per cent. of nitrogen, 0.01 per cent. of phosphoric acid and 0.19 per cent. of potash. ‘The wood of the whole tree, roots and branches, averages 60.83 per cent water, 1.50 per cent. ash, 0.35 per cent. nitrogen, 0.05 per cent. phosphoric acid, and 0.17 per cent, potash. Estimating 40 such trees per acre, there would be removed from the soil in a crop of ten bushels per tree, in the fruit alone, 32 pounds of nitrogen, 8 pounds of phosphoric acid, and 45.6 pounds of potash. A crop of wheat of twenty bushels per acre removes from the soil in rain and straw about 29 pounds of nitrogen, 9 pounds of phosphoric acid and 5 pounds of potash. It will be seen then that the draft on the soil, especially in potash, is far heavier from a crop of apples than a crop of wheat. It has taken a large amount of plant food to build up a big tree, and to supply its an- nual crop of leaves and fruit; and in most cases the owner of the orchard expects to get a crop of hay or pastureage from the orchard, too. And then we hear people wonder why they do not get fruit as their fathers did on the same farm. They manure their wheat, but starve the orchard which is draw- ing on the mineral resources of the soil more than three times as much as the wheat is. To supply the manurial needs of the fruit alone on a bearing orchard as above, would require per acre 200 pounds of nitrate of soda, 60 pounds of acid phosphate and 100 pounds of muriate of potash. If, however, the orchard is in sod and the grass is kept mown for the benefit of the trees, there will not be the need for that amount of nitrogen, as there will be a large amount of organic matter returned to the soil, and for the benefit of the trees themselves we would increase the amount of phosphoric acid, and make the dressing of nitrogen in the form of tankage or cotton seed meal, and use 300 pounds of acid phosphate, 200 pounds of cotton seed meal and 100 pounds of muriate of potash per acre. Or it might be as well to put the phos- phoric acid in the form of floats or pulverized rock, which would be more slowly available it is true, but would, nevertheless probably be better for trees than the more readily available acid phosphates. CHAPTER XLV. THE PEAR. The climate and soils of the Atlantic coast of the United States, from Boston to Cape Hatteras, are peculiarly adapted to the successful culture of the pear, and the section of this range best adapted to pears is that known as the Delaware and Maryland Peninsula. In this favored region the pear attains a size and quality unknown in most other sections. We once showed pears from the eastern side of the Chesapeake Bay, at an exhibition in Baltimore, in competition with the best Boston growers, and our pears of the same varie- ties were so far superior to the Boston pears that the Boston men did not recognize the varieties. But the pear has a wide range over the country where it will succeed very well. It likes a deep and fertile clayey loam, and during its early growth should have about the same treatment as to feeding that we would give the apple. Much attention was formerly given to the cultivation of the pear on the Angers quince stock, in order to produce a dwarf and early fruiting habit, as the small range of the quince roots would for a while, check the naturally rapid growth of the pear, and thus throwing it into the making of fruit spurs would still further check the rapid growth of the tree and continue it in a fruitful condition. Some varieties on the quince did not fruit excessively and finally developed into standard trees, and then unobservant men said that the trees had formed roots from the pear stem. The fact is that when we put a pear on a quince root, and allow no further shoots of quinee to grow, all the subsequent growth of roots is pear and not quince, for the leaves of a tree form all the material for growth, and pear leaves form focd for pear growth for limbs and roots alike. Hence all subsequent growth of the tree is pear overlaying and extending from the old quince roots, and if the growth of the tree is not retarded by excessive fruit bearing, it will finaliy develon into a standard tree, and not a root can be found directly proceeding from the pear stem. This fact in vegetable physiology has been strangely overlooked by all (320) THE PraAR—321 writers on fruit culture. Any nurseryman of experience knows that while he may graft a large block of various kinds of apples on the same lot of seed-— ling crabs, each variety will form from the piece of crab root its own peculiar root system. Some of the trees will be easy to dig while others will form a root system which makes them harder to lift. What has made this difference ? Not the stock, for the stocks are all the same, but the top which was grafted on it has made the root system peculiar to the variety. No matter what the stock used in working a tree, the subsequent growth will be that of the top, whatever that may be; for all elaboration of material for growth is done by the leaves, and partakes of the nature of the plant from which the leaves come. The quince stock, with roots feeding in a more limited space than the pear roots, will for a time check the rapid growth of the pear and throw it into fruiting earlier. But of late years so many varieties of pears have been introduced which bear at a comparatively early age on the pear stock, that less attention is now paid to dwarf trees on the quince. The introduction of hybrids with the Chinese sand pear has given an impetus to pear culture in the South, where the old varieties are seldom a success; and while the Kieffer and Leconte are not of the highest excellence, they flourish and give large crops in sections -of the country where no other pears can be grown, and torm the starting point for improved varieties adapted to Southern conditions. Only a few days ago we, as Judge, examined a seedling pear from the Kieffer which marks a real advance. It is supposed that the Kieffer is a seedling from the Bartlett crossed with the Chinese sand pear, and this seedling seems to give further evidence that this is true, for while it has the general shape and ap- pearance of the Kieffer, it has a brilliant red cheek, and one with his eyes shut would pronounce it a Bartlett. When seedlings of such excellence can be produced from Kieffer there is a wide field for the workers in the South, in improving the pear that will succeed there. While this book is not intended to treat of the fungus diseases of fruits and other plants, but rather on their growth and feeding, we cannot refrain from saying here a few words in regard to the disease which, so far, has baffled fruit growers in preventing it. This is the fire blight of the pear, which also at times attacks apples and quinces, but hardly to the same extent that it does the pear. All sorts of odd notions have prevailed among intelligent growers as to the cause of pear blight, and some still have a notion that it is caused by frozen sap in winter. But the investigations of scientists have fully demonstrated that the blight is caused by one of those microscopic forms of plant life known as bacteria, which gets into the shoot in the early spring, probably by means of the bees which visit the blossoms. As these grow down- 322—-Crop GROWING AND CRoP FEEDING wards, destroying the young growing tissues between the bark and wood, there ‘is no way to get any fungicde material to them. Though the blight begins its growth early in the season, its presence is only known to the ordinary observer by the sudden wilting and blackening of the foliage on the affected mb. The only way to check it is to cut the affected limb off well into the sound wood, and to keep the knife used constantly sterilized by dipping it into a solution of carbolic acid, to prevent transferring live bacteria to sound wood. ‘Then burn all the cut-off wood at once, and keep on planting more pear trees. Some varieties are less liable to the bight than others, but all are to some extent, subject to it, and if anyone tells you that a certain variety is blight proof you can be sure he does not know what he is talking about. Since writing the foregoing I have visited one of the famous Pippin or- chards in the mountains of Albemarle County, Virginia. ‘The owner wished me to give him some advice in regard to the twig bight, which was very trou- hlesome. I spent some hours in the study of a large number of trees, and what struck me most was the fact that there was no signs of blight on the trees which were destitute of fruit, but on those carrying a crop there was uniformly blighted twigs. This fact seems to confirm the experiments made at one of our Stations, showing that the point of infection with the blight bacteria is the blossoms, and when these fill without setting fruit there was - no infection. 'The important point in preventing fire blight in pears and apples is to watch its first start in spring and cut it out before the whole limb is affected, for there is no infection later in the season. One thing that we have learned by experience, and that is that pear trees growing in sod are far less affected by blight than those cultivated and heavily manured. The rank growth induced by heavy manuring is peculiarly the prey of the blight. We once had two plantations of pears in a similar soil, and only separated by an evergreen hedge. One lot were in a piece of land which was used as a vegetable garden and annually manured and well culti- vated. These blighted continually, with the sole exception of a tree of the Buerre D’ Anjou, which had such a luxuriant growth and spreading habit that nothing would grow near it, and the land there was only cultivated to the extent of the wide spreading limbs. Over the other side of the hedge was an- other plantation of pears which were set on a lawn and had never been culti- vated from the start. The lawn was constantly mown and kept in perfect order, and all the cut grass allowed to remain where it fell. It was also an- nually top dressed with bone and potash. We never saw a blighted limb on these trees in the six years we had them in charge, and while they did not make as heavy growth as the trees in the cultivated land, they bore annual crops of fine fruit. THE PEAR—323 Hence, with the pear as with the apple, we would cultivate the trees in grass as soon as they have attained to a bearing size. No one ever has trees to blight, so far as we have observed, till they get to blooming, and this is ad- ditional evidence that the bacteria gain entrance through the blossoms. The pruning of the pear tree from the start must be done in accordance with the particular habit of the tree, for pear trees vary greatly in their habit of growth. Seckel needs hardly any pruning to keep it in perfectly round and symmetrical growth, except to prevent too dense a head. Sheldon tends to grow up into a Lombardy poplar form and needs shortening back to buds on the outside of the shoots, to induce a more spreading habit. Some of the books are fond of showing pears trained in a pyramidal form, but we have al- ways found that for our climate the round and open headed form is the best for all our fruit trees. Branched low to the ground and trained into this form they are better for our purposes than pyramids which need the constant care of an expert. With trees like Kieffer and Leconte, which are inclined to make long shoots, it is important to practice summer pinching to induce the formation of a compact head. We have seen many Kieffer trees which have been allowed to take their natural habit, and which soon load the long shoots with fruit and break with the weight. If these long shoots had been checked by pinching the terminal buds when a foot or two long, they would have branched and become more compact. Summer pinching is often of greater value than winter pruning with such rapid growers as the Kieffer and Vicar. With feeble and crooked growers like the Bartlett, hard and close pruning should be the rule while young, and no summer pinching should be done, for the Bartlett needs encouragement to grow rather than checking. Winter cutting increases growth and summer pinching checks it. Bear this in mind in all your pruning. FEEDING THE PEAR. What we have said in regard to the feeding of the apple orchard will ap- ply with equal force to the manuring of the pear. Avoid too much nitrog- enous manure, and too rank a growth if you want to avoid the blight; but after the trees have come to bearing age put them in grass and keep the grass as you would a fairly good lawn. An annual topdressing of raw bone meal and muriate of potash, in proportion of five of the first to one of the latter, will keep pears in sod in a sufficiently thrifty condition, and they will be far less liable to blight than if cultivated. Even in the young and formative stage of the trees of apples and pears, the cultivation should not be kept up later than July, so as to give the trees time to ripen the wood growth of the 324—-Crop GROWING AND Crop FEEDING season, and to be in a better condition to pass through the winter. Remember too, what we have said in regard to cultivation, that if the land is cultivated to the outer edge of the limbs it is sufficient, since the feeding roots are out beyond the limbs and not at the base of the stem. The New Jersey Station suggests the following in regard to feeding the pear: “T'wo good mixtures of fertilizers to apply are, first, equal parts of ground bone, muriate of potash and acid phosphate; second, one and on-half parts of ground bone and one part of muriate of potash ; 500 pounds per acre is usually applied. Where nitrogen is needed, nitrate of soda is one of the best forms, but it may be omitted when crimson clover is grown.” CHAPTER XLVI. PEACHES, PLUMS AND CHERRIES. The so-called “stone” fruits all require nearly the same treatment. The peach, being a short lived tree, needs constant and regular cultivation annu- ally during the whole term of its existence. But, as in the case with young apple trees this cultivation should not be continued too late in the season, and some cover crop should be sown to protect the soil during the winter and to be turned under in the spring for the benefit of the trees. In the peach growing region of Delaware and Eastern Maryland it has become a common practice to sow the orchard in crimson clover in July, at the close of cultivation, and to plow it all under in the spring. PLANTING A PEACH ORCHARD. Peach trees should always be but one year old from the bud when set. In the South the planting can be best done in the fall, at any time after the leaves fall up to Christmas, but in cold latitudes the planting should be deferred till spring. We always prune the roots of a peach tree rather closely, leaving only the stout roots five or six inches long, as the small fibres will all be dry and worthless in any event and the young roots put out more rap- idly from a clean cut surface. We are not yet ready to adopt the plan recom- mended by Mr. Stringfellow, of Texas, to cut off the roots to a mere stub and set the trees in holes made with a crowbar, in sod land. though trees thus treated will live and grow. We prefer to dig a moderate sized hole, no deeper than the plowing has been, and then to ram the soil tightly to the pruned roots. After planting, we trim off all side shoots closely, and then head back the main stem to about twenty inches from the ground. In the Spring, when growth begins, we select the best situated buds, three or four, near the top, to form the head, and rub off all others. | During the summer we watch the young shoots and if one limb is inclined to grow too fast for its fellows. and thus form a one-sided head, we pinch its tip and check it. (325) 326—Crop GROWING AND Crop FEEDING The second spring the pruning needed will be to shorten back the young growth of the previous year nearly one-half, and to thin out the shoots that may interfere with each other in the centre of the tree. The peach bears its fruit on the wood of the previous year, and the tendency of growth is toward the extremity of the branches, and finally to leave the centre of the tree des- titute of young wood. The annual pruning, then, should be directed towards the maintenance of fruit wood well distributed throughout the head of the tree, so that the load of fruit will be carried without overloading the extremi- ties and causing the limbs to break. FEEDING THE PEACH. Heavy applications of nitrogenous fertilizers are to be avoided in peach culture, as encouraging too rank and sappy a growth and conducing rather to wood than fruitfulness. If the orchard is sown annually in crimson clover or some other legume growing during the winter, it will get all the nitrogen needed without artificial application of phosphoric acid and potash, and es- pecially potash. Frequently an unhealthy and yellowish condition of the tree has been cured by the application of potash, and this fact has caused some to believe that the disease known as “yellows” can be cured by potassic appli- cations, which is hardly possible. The yellows is caused by a fungus, some think, on the roots of the tree; a species of the mushroom family. If this is true, it would seem that the best way to fight the yellows is with fungicides applied to the soil. The application of phosphoric acid and potassic fertil- izers in liberal amount will greatly aid the growth of the clover, and the in- creased growth will enable the plant to do more nitrogen catching, so that in « few years it may be found best to cut the clover for hay rather than to con- tinue the accumulation of humus material in the soil. Of this, however, every grower must judge for himself. After plowing under the clover, the clean and shallow cultivation of the soil is important, for no weed growth should be allowed on the land to withdraw moisture from the trees during {heir early summer growth. Some of the best work with the peach has been done by the Connecticut Agricultural Experiment Station. The report of the Connecticut Station for 1895 has the following state- ment in regard to the composition of the peach: - “When peach trees are set 18 feet apart each way, as is the common prac- tice in this State, there are 130 trees to an acre. Experienced growers reckon three baskets to a tree, an average yield for orchards five years planted. Four baskets per tree is a maximum crop. From the above data are calculated the quantities of nitrogen and mineral matter removed from an acre of 130 trees by the average crop of three baskets of peaches per tree, viz.: PEACHES, PLUMS AND CHERRIES—327 NITROGEN AND ASH INGREDIENTS IN A PEACH CROP OF 390 BASKETS PER ACRE. “Nitrogen, 19.7 pounds; potash, 21.9 pounds; soda, 1.2 pounds; lime, 1.0 pounds; magnesia, 1.0 pounds; oxide of iron, 0.4 pound; phosphoric acid 4.2 pounds; sulph. acid, 1.0 pounds; chlorine, 0.4 pound. “Contrary to the commonly received idea, the pulp of the fruit contains the greater part of both the nitrogen and mineral matters. Only about one- fourth of the nitrogen and one-tenth of the ash elements are contained in the stones. While these quantities of nitrogen and mineral matters are smaller than those removed by many other garden or field crops, it does not follow that peach trees need less care for their proper manuring. The quantities of plant food required for the yearly growth of wood and leaves must be considerable. Young twigs contain a larger proportion of nitrogen, phosphoric acid and potash than old wood. But we have no exact data at hand from which to compute the yearly demand of the growing peach tree on the plant food in the soil. Field experiments demonstrate that liberal fertilization is neces- sary to secure the most profitable returns from peach orchards.” The figures given simply show what is carried off from the acre of land by the crop of peaches, and indicate that an annual return of 20 pounds of nitrogen, 22 of potash and 5 of phosphoric acid will restore to the land what the average peach crop requires, and that 27 pounds of nitrogen, 30 of potash and 7% of phosphoric acid will make good the deficit caused by a maximum crop, provided there are no other sources of loss besides the export of fruit. But it is one thing to return to the soil what the crop has removed and, to some extent, another thing to maintain the fertility of the soil so far as relates to the suitable supply of plant food. The active feeders of the tree in the soil are the young rootlets and root hairs that are put forth the current: year. The roots of five or two years ago are probably themselves totally incapable of feeding the plant. Even last year’s roots are of little use except as they are necessary bases of the new rootlets that develop this year. The young roots of each successive year of growth thus occupy different positions in the soil, and since most of the plant food in the soil is incapable of movement, much of it, at any time, is out of the reach of the rootlets, and to be fertile the acre of soil must contain many pounds of plant food in order to insure to the crop the few pounds which it requires. “Tf the soil is very rich to begin with, the trees may produce -well for years without fertilizers, but the New England hills that furnish the best orchard sites, are, as a rule, not fertile, and must be well enriched to make them profii- able. It is now no doubt well known to orchardists that soils have the power 328—Crop GROWING AND Crop FEEDING of changing the solubility and availability of the plant food which may be put upon them in fertilizers. It is well proved that phosphoric acid applied in water-soluble form, becomes, in many soils within a few days or weeks, quite insoluble in water, and for a considerable time gradually diminishes in availability. Cer- tain soils contain enough phosphoric acid to serve many large crops if it were freely accessible to their roots, but that this phosphoric acid is not imme- diately available is demonstrated by the fact that moderate dressings of plain superphosphate strikingly increase the yield. What has just been stated of phosphoric acid is equally true of potash. As to nitrogen, we know much but not nearly enough of its incomings and outgoings. | We know that the soils of forests, meadows and moist pastures gain in nitrogen, while dry, naked or tilled ground loses nitrogen from year to year. We know that clovers and legumes generally rapidly enrich or may enrich the soil they grow upon, as respects nitrogen, while the culture of cereals, root and fibre crops, and garden truck, diminishes and exhausts the soil nitrogen. As a rule in case of soils that have a fair proportion of fine clayey matters, all the phos- phoric acid and potash that may be needed to aid any crop, if once applied cannot escape from the soil and will be retained near the surface, will not in any event descend much below or spread from where it has been placed. With nitrogen it is very different and loss of this element may occur in three ways: First, by leaching out in the drainage water as nitrates; second, by escaping into the air as nitrogen gas, and, third, by conversion into compara- tively inert forms, such as exist in leaf mold, swamp muck and peat, or in the cell tissues of fungi and shells of insects. For this reason, soluble and active and therefore costly, fertilizers are best applied in small doses, at or near the surface of the ground and at short intervals; while cheap, insoluble and slowly-acting manures may be used in large applications and deeply mixed in order to establish a more permanent state of fertility. The amount of any needed fertilizer element to be supplied annually, must be learned by experi- ence and experiment, since soils vary greatly in their composition and quali- ties; and the supply must commonly be several or many times larger than the amount annually taken off in the crop. One fertilizer element that is scarcely noticeable in the export of the peach crop, is nevertheless important to its production. The chief ingredient of the ash of the wood, bark and leaves of all trees is generally lime. The wood of healthy peach twigs of one year’s growth contained 1.87 per cent. of ash, of which 54.2 per cent. was lime, 9.5 per cent. magnesia, 16.3 per cent potash, 4.3 per cent. phosphoric acid and 6.9 per cent. sulphuric acid. The mature leaves of oak and chestnut trees con- tain about 30 per cent. of water, 3 to 4 per cent. of ash, and of the latter 30 PEACHES, PLUMS AND CHERRIES—329 to 40 per cent. is lime. Where the water of wells or springs coming from the soil, is soft or but slightly hard, the orchard needs lime to be supplied. This substance dissolves rather freely in the drainage water and is, therefore, sub- ject to constant waste. Wood ashes and lime should be broadcasted at the rate of 500 pounds per acre annually, and this dressing will be of the greatest benefit to the crimson clover now so commonly used in the orchards.” Our own opinion is that no peach or other orchard would need so frequent an ap- plication of lime, and that the above amount in connection with grass in the apple orchards and the annual clover in the peach orchard during the latter part of the season, would be ample for all needs if applied once in three years. These remarks in regard to the fertilization of the peach are equally applica- ble to the fertilzation of orchard trees of any kind, and the lime is even more important in the apple and pear orchard than in the peach orchard. THE PLUM. While the statement that plums require a heavier soil than peaches is true, especially of the European (or Domestica) sorts, the Japanese and American varieties will thrive on a great-variety of soils, and we have seen them bearing heavy crops on a deep sand. Many nurserymen bud their plums entirely on peach seedlings, but this has one difficulty. While the peach stock makes a vigorous tree it is just as liable to the peach tree borer at the crown of the root as the peach; hence many have begun to use the Marianna plum as a-stock and find that it is better than the peach, as it thrives on a greater variety of soils and resists the borer better, while it has root develop- ment enough to promote a vigorous growth. The budding is done in August, at the same time the general budding of the peach is done, and the buds re- main dormant till the following spring. Some nurserymen insert buds of the plum and peach in June and get a small growth the same season, but the practice is not to be recommended as a general rule, though careful growers can make just as good trees from the little June-budded stocks as any, and for our own planting we rather prefer them; but the average planter had better take the yearling trees. In planting, we prune the roots to four to eight inches long. The finer rootlets will have all dried and become useless and new roots are produced on the ends of the clean cut roots sooner than from the dried up fibres. |The peach and all other fruit trees we treat in the same way. Of late years there has been a great deal of controversy over a method of planting advocated by a grower in Texas. He prunes off all the roots of the tree and leaves only a stub 3 or 4 inches long. He then makes a hole with a crowbar in the sod, sticks the tree in and rams the earth to it. He claims 330—Crop GROWING AND Crop FEEDING that trees treated in this way will make better trees and better roots than if planted in a big hole with all the roots. Climate has a good deal to do with these things, and experiments in a more northern latitude have not been as favorable as those made in the South, where trees planted in this way certain- ly do grow and thrive remarkably. The planting should be done in the South as soon as the leaves are off in the fall and up to Christmas, and in the North probably April would be the better time. For most of the Japan plums a dis- tance of 16x20 feet will be about the proper space for the planting. As with the peach, the plums should, during the early stages of their growth at least, receive careful culture during the early part of the summer, and after July should have a crop of crimson clover sown among them. After the trees have gotten well to fruiting, they can safely be put into grass and used as a chicken yard. The pruning is about the same we give the peach, and the manuring we have already men- tioned. If the clover or other nitrogen collecting legume is grown among the trees, with a good application of phosphoric acid and potash, there will be no need for any nitrogenous manures, but the application of the phosphoric and potassic fertilizers should be faithfully kept up annual- ly if the production of maximum crops is desired. All the Japan plums are inclined to overbear, and there is no fruit grown that can be so improved by systematic thinning of the young fruit. Thinning not only improves the size and quality of the fruit and takes off the strain from the vitality of the tree, but it also lessens the tendency to rot where the fruit grows touching each other. But pick the fruit by hand and do not merely shake the trees or thresh off the fruit with a pole and thereby bruise many that are left. With the domestica (or Kuropean) sorts it is essential that daily jarring of the trees be practiced so as to catch the curculio which lays eggs in the fruit and makes them wormy. © If the chickens, as I have said, are allowed access to the trees and the jarring is done daily, they will gather up the bitten fruit and insects, and keep the trees comparatively free. A large machine like an inverted umbrella is used in large orchards for the collecting of the insects. It is made on a stout frame with cotton cloth and a slit on one side so that it can be slipped around the body of the tree. If the machine has an opening at the bottom under which a pan of kerosene is attached, the insects and bitten fruit roll into this and are at once destroyed. Plums prefer rather a heavier soil than the peach, and thrive well in sod. We have here an old plum tree, growing in a hollow in the woods, where it has never received any cultivation whatever. It stands in the shade of large oaks and other trees of the original forest, and yet, year after year it bears crops of the finest plums. How old it is we do not know for it was there many PEACHES, PLUMS AND CHERRIES—331 vears before we came into possession. It would hardly be classed as a remark- ably thrifty tree, and yet it is healthy, free from black knot, and does not seem to be troubled by the curculio. Our chickens have the free range of the woods where it grows, and this fact may, to some extent, account for its free- dom from insects. In fact, from our experience in the past, we believe that a chicken yard is about the best place for plum trees. All the old European varieties are peculiarly liable to the attacks of the curculio, and a regular jarring of the trees in a poultry yard will keep them down as effectually as any plan we have ever tried. Then, too, the droppings of the poultry will give much plant food to the trees. Plums of the more recently introduced Japan- ese varieties are inclined to grow long, rank shoots and to get overloaded. The pruning should be similar to that of the peach to preserve the trees in a round headed shape, and to keep the fruit spurs well distributed over the tree. One fact in regard to plums, and especially the native and Japanese sorts is the repugnance they have in many varieties to self impregnation. Hence it is important that the varieties should be well mixed together in the orchard. A farmer who had an orchard of the Wild Goose plum asked me one day why it was that only one corner of the orchard bore heavy crops. | asked him if there were any other plum trees near that corner. He said that there was a hedge row of the native Chicasa plums there. The reason was then quite apparent, for the wild plums were helping to set the fruit. While plums do well in a sod after they have attained a bearing size, we would, as in the case of apples and pears, grow the sod solely for the benefit of the trees and would not cut hay from it, but simply keep it mown and let the grass decay where it falls. In addition to this an annual application of 300 to 400 pounds per acre of a mixture of acid phosphate and muriate of potash, in proportion of five parts of the phosphate to one of the potash, will keep up the fertility of the soil and the health and productiveness of the trees. CHERRIES. Cherries, like plums, will thrive well in uncultivated soil, as is well at- tested by the immense trees along the fence rows in the Middle Atlantic States. But the Morello class of pie cherries thrives best under the same treat- ment as the peach, and should be well cultivated if fine crops are expected. The sour cherries are the only ones that can be grown with success in the South Atlantic coast region, though the finer sorts thrive in all the mountain country of the Southern Alleghanies. The same treatment as to manuring that has been advised for the peach will suit the cherry as well. In the South, the trees of the larger cherries should always be upon the Mahaleb stock, and 332—Crop GROWING AND Crop FEEDING headed very low to shield the trunks from the sun. In fact, this low heading of fruit trees, while the best anywhere, is absolutely essential in the South, if we are to prevent sun scalding on the southwest sides of the trees. Cherry trees in more northern sections are budded for the sweet varie- ties on the Mazzard stock, as this makes a larger tree than the Mahaleb; there only the sour cherries are worked on the Mahaleb stock. The trees are usu- ally set at two years old, but we prefer to set one year trees, as we can then better start the formation of the low head the cherry should always have. With the sour cherries it is essential that the orchard should have good culti- vation throughout its entire life, and the same is true for the best success in orchard culture of any of the varieties, though there are thousands of the most magnificent cherry trees along the fence rows on the Delaware and Maryland Peninsula which have never received any cultivation at all further than that given the fields on which they border; and yet the trees are vigorous and healthy and produce enormous crops. The sweet cherry tree is a gross feeder and will find food by means of its wide-spreading roots in a soil where the dwarfer, sour cherries would not thrive, and if the soil for these is made too rich they may run merely into an annual wood growth and bear little fruit. The sowing of a crimson clover crop in the cherry orchard is just as import- ant and useful as in the peach orchard, and all the nitrogenous matter the trees need can be supplied in this way. But, as has been well said in the bul- letin of the Delaware Station, the plowing under of this clover in the spring should be done as soon as the land is in order to plow, for early plowing and subsequent shallow cultivation, is an important matter for the retention in the soil of the moisture the cherry needs for its best development. The Delaware Station advises the application of 300 to 500 pounds of acid phos- phate and 150 to 250 pounds of muriate of potash per acre to the cherry orchard. One of the most extensive cherry growers in Western New York applies three pounds of muriate of potash and two pounds of acid phosphate per tree, either in the spring or when seeding to crimson clover. The regu- lar application of phosphoric acid is an important thing for the proper ma- turity of the wood in the fall. As with all the stone fruits that bloom early, the cherry will be safer in a northern exposure in most parts of the country, so that the blossoming period may be retarded. The most profitable sour cherries for. market are the Montmorenci and the Early Richmond. The same jarring that is practiced with the plum and peach is useful in catching the curculio on the cherry, and should not be neglected. The best remedy against sun scald and bursting of the bark is to head the trees close to the ground and get the protection of the top as soon as possible. CHAPTER XLVII. THE GRAPE. The wide range of soils and climates in the United States in which grape culture succeeds is an evidence of the great adaptability of the vine for varied conditions. The grape thrives well on soils of very different character, and is at home anywhere in a soil abounding in the plant foods it needs; provided it has a well drained location, for it will not thrive with wet feet; a compact clay is about the poorest soil for the grape. The Delaware, which is inclined to be a feeble grower in such a soil, grows with the utmost luxuriance on a shaly hillside and finds its most congenial home in the sandy uplands of the South. On these sandy lands we found that there is no plant grown which is so readily affected by the commercial fertilizers as the grape. And we have also found that a complete fertilizer, in which there is a fair percentage of nitrogen and a large percentage of phosphoric acid and potash, is the best for the grape. With such a fertilizer we grew the Niagara grape to such a size that we were compelled to pack them in the carrier baskets used for peaches, as the smaller grape baskets were entirely too small for the clusters. Our vines were planted in rows ten feet apart and eight feet from each other in the row. We used a modification of the Munson trellis. Posts were set in the rows, and cross pieces two feet long nailed across their tops four feet from the ground. Wires were stretched along the line of posts and two others along the ends of the cross pieces. The arms were taken along the central wire and the fruit shoots hung over the outer wires so as to completely shelter the grapes beneath. This style of trellis is convenient for the cultivation, pruning and harvesting of the grapes, and there is far less rot than on an unsheltered, vertical trellis. For a fertilizer we would advise the following, tomakeaton. Acid phosphate, 1,000 pounds; cotton seed meal, 600 pounds ; and muriate of potash, 400 pounds. Of this we would use 400 to 500 pounds per acre, annually on a sandy soil. A ton of fresh grapes will remove from the soil 3.2 pounds of nitrogen, 0.2 of a pound of phosphoric acid and 5.2 pounds of potash. In the wood- growth the amount of phosphoric acid is greatly larger than in the fruit, and the amount of potash nearly three times as great. The main requirements, (338) X 334—Crop GROWING AND Crop FEEDING then, evidently are phosphoric acid and potash. As in the case of the orchard cf peaches, the vineyard will be greatly better off if the cultivation ceases at midsummer, and the spaces between the rows are sown with a leguminous crop that will remain during the winter. With such a growth there will soon be no need for any applications of nitregen in the fertilizer, which can then be reduced to the two constituents, acid phosphate and potash. The Southern species of the Vulpina (Rotundifolia) genus, the “Seup- pernong,” are commonly grown from Southeastern Virginia southward along the coast on horizontal arbors, and there is a belief that they should never be pruned; and there are, in the South, immense vines that cover acres with the growth from a single trunk, and bear profusely. But proper pruning is just as good for the Scuppernong and other grapes of this class as for others, with the difference that these grapes produce fruit from two-year-old wood, while the Labrusca varieties grown in the North bear on one-year wood. cede, <5 os 10.00 12.10 0.12 0.25 Ce GAD AWG oo ee ae Fists a ele eles) s 5 0 ou 10.00 0.77 0.07 0.17 Opke ATO eaileg ta) 2 24 intake mbes sees 10.00 6.29 0.10 0.18 CHE ROY WOOK sf 2 5 oa.c owe nterhnn dee soe 10.00 0.57 0.06 0.14 OUR Aw tine.
