O Seles THE FERTILIZER INSPECTION FOR 1915. The samples of fertilizer for the 1915 inspection were collected by Mr. A. G. Weeks for the Commissioner of Agriculture, Andrew L. Felker. One hundred and fifty- eight samples were taken and analyzed. This is the small- est number of brands sampled for a number of years. This condition is due to the potash situation which caused a curtailment in the number of brands manufactured. The amount of potash in many of the brands has been reduced, but for the most part the guaranteed amounts have been found or closely approximated. The potash situation does not promise any improvement for another year. Unless shipments can be resumed very shortly, practically no potash can be supplied in next year’s goods. The owners of hill lands in New Hampshire are particularly fortunate at this time because the potash is the least necessary of the fertilizer constituents. It might be well to point out here that two brands of fertilizers have been sampled and analyzed this year which do not fall into any class with the other brands. The ‘‘New Mineral Plant Food,’’ widely advertised, is not a fertilizer in the commonly accepted sense of the word. It is a ground rock product containing very limited amounts of fertilizer constituents, all of which are practically in- soluble. ‘‘Prepared Humus’’ is another product which sells at a relatively high price and contains relatively small amounts of soluble fertilizer constituents. This product appears to be little more than peat which has been dried and ground. The analytical work in this report has been prepared with the assistance of Messrs. M. J. Broggini, A. J. Grant, J. Barnardi, E. N. Sanders, P. S. Willand and C. B. Tibbitts.
