SOILS  OF  THE  EASTERN  UNITED  STATES  AND  THEIR  USE-AXXVI. 


THE  VOLUSIA  SILT  LOAM. 

GEOGRAPHICAL  DISTRIBUTION. 

The  Volusia  silt  loam  occurs  at  the  higher  altitudes  in  the  plateau 
country  which  stretches  from  the  vicinity  of  the  Delaware  River 
westward  along  the  line  between  New  York  and  Pennsylvania  to 
the  eastern  boundary  of  Ohio,  including  considerable  areas  in  the 
northeastern  counties  of  that  State.  It  is  not  found  south  of  the 
extreme  limits  of  glaciation.  Within  this  region  it  has  been  encoun- 
tered in  eight  ditiPerent  soil  survey  areas  and  has  been  mapped  to  the 
total  extent  of  821,184  acres.  It  is  estimated  that  the  type  covers  not 
less  than  5,000,000  acres  in  the  general  region. 

CHARACTERISTICS  OF   SOIL  AND   SUBSOIL. 

The  surface  soil  of  the  Volusia  silt  loam,  to  an  average  depth  of 
8  inches,  is  a  yellow  or  light-brown  silt  loam.  The  color  varies  with 
the  local  conditions  of  drainage  and  with  the  amount  of  organic 
matter  present.  In  poorly  drained  areas  there  is  a  tendency  toward 
a  gray  or  ash  color,  while  in  well  tilled  fields  the  surface  soil  is 
usually  brow  n.  From  8  inches  to  about  20  inches  the  subsoil  is  usu- 
ally a  pale-yellow  silt  loam,  underlain  by  a  compact  mottled  gray 
nnd  yellow  heavy  silt  loam.  The  entire  soil  mass  is  filled  with  angular 
fragments  of  shale  and  sandstone  rock  of  all  sizes.  The  underlying 
shale  or  sandstone  rock  is  sometimes  encountered  at  shallow  depths, 
but  is  usually  buried  by  3  to  5  feet  of  soil  and  subsoil  material  cariy- 
ing  a  few  scattered  bowlders  of  foreign  rock. 

The  Volusia  silt  loam  is  easily  distinguished  from  the  soils  of  any 
other  series  by  the  univei'sal  presence  of  the  flat  shale  and  sandstone. 
It  differs  from  the  Volusia  loam  in  occurring  at  higher  elevations 
and  in  the  generally  lighter  color  of  soil  and  subsoil.  In  general,  it 
does  not  possess  the  considerable  depth  to  underlying  rock  of  that 
type. 

SURFACE  FEATURES  AND  DRAINAGE. 

The  Volusia  silt  loam  covers  the  rolling  surfaces  of  the  high  hills 
which  have  been  carved  from  the  plateau  region  of  southern  New 
York,  northern  Pennsylvania,  and  northeastern  Ohio.    At  the  highest

elevations  it  is  only  rolling,  but  the  hills  are  separated  by  deep-cut, 
steep-sided  valleys,  down  the  slopes  of  which  the  type  extends.  Its 
surface  varies,  therefore,  from  nearly  level  or  gently  rolling  to 
steepl}'^  sloping  and  almost  precipitous.  The  greatest  part  of  the 
type  lies  at  altitudes  ranging  from  1,200  to  2,000  feet  above  tide 
level.  Some  portions  of  it  rise  to  an  extreme  elevation  of  approxi- 
mately 2,300  feet,  while  the  areas  found  in  northeastern  Ohio  are 
much  less  hilly  and  lie  between  900  and  1,100  feet. 

The  surface  drainage  of  the  Volusia  silt  loam  is  fairly  adequate 
over  the  greater  part  of  the  type.  Numerous  springs  found  upon 
the  hill  slopes  give  rise  to  small  swampy  areas  and  some  of  the 
more  level  tracts  are  so  closely  underlain  by  impervious  rock  as  to 
be  poorly  drained.  The  greatest  difficulty  with  drainage,  however, 
arises  from  the  compacted  and  dense  condition  of  the  subsoil  just 
below  plow  depth.  Long-continued  plowing  to  the  same  depth,  often 
at  times  when  the  subsoil  was  too  wet,  has  compacted  and  hardened 
the  layer  upon  which  the  plow  sole  rides,  forming  Avhat  is  locally 
known  as  "  hardpan."  This  hardpan  seriously  interferes  with  the 
natural  internal  drainage  of  the  type. 

Upon  the  more  level  areas  of  this  soil  erosion  is  not  a  serious  prob- 
lem, but  there  are  many  steep  slopes  within  its  boundaries  which  may 
be  protected  from  destructive  washing  only  through  remaining  in 
permanent  pasture  or  in  woodlot  or  forest.  From  many  such  slopes, 
denuded  of  forest  when  the  region  was  cleared,  practically  all  of 
the  original  soil  has  been  removed,  leaving  only  a  mass  of  shale  frag- 
ments mingled  with  a  small  amount  of  earth.  Such  slopes  should 
never  have  been  cleared.  They  comprise  possibly  15  per  cent  of  the 
total  area  of  the  type. 

LIMITATIONS    IN    USE. 

The  Volusia  silt  loam  occurs  at  high  elevations  in  a  cold  northern 
region.  It  is  a  moderately  well  drained  soil,  of  rather  heavy  texture, 
suited  under  ordinary  conditions  only  to  the  production  of  hai*dy 
crops  which  mature  in  a  short  growing  season.  The  greater  pro- 
portion of  the  type  lies  at  too  great  an  elevation  to  permit  of  ma- 
turing any  variety  of  corn  except  the  flint,  and  even  this  can  only 
be  grown  for  silage  in  the  majority  of  years.  The  crop  adaptation 
of  the  type  is  therefore  restricted  by  its  inherent  characteristics  and 
by  its  climatic  surroundings  to  buckwheat,  oats,  Irish  potatoes,  and 
hay.  Other  crops  are  grown  to  a  limited  extent,  and  the  better 
drained  areas,  which  may  also  lie  at  lower  elevations,  possess  a 
greater  range  in  crop  adaptations  than  the  general  average  of  the 
type. 

A  considerable  proportion  of  the  total  area  of  the  Volusia  silt  loam 
lies  upon  the  rolling  tops  of  the  high  hills  and  is  unfavorably  located

with  respect  to  transportation  and  shipping  points.  Even  where 
the  actual  distance  is  not  great  there  is  frequently  a  long,  steep 
grade  from  the  farm  down  to  the  main  routes  of  transportation. 
This  limitation  has  affected  the  economic  conditions  and  methods  of 
farming  in  the  region  occupied  by  this  type.  Only  such  farm  prod- 
ucts prove  profitable  as  may  be  grown  in  a  cold  climate  and  easily 
transported  to  market. 

In  former  times  sheep  growing  and  the  production  of  beef  cattle 
constituted  a  considerable  industry  upon  this  soil,  but  competition 
with  western  ranges  reduced  the  profits  and  a  system  of  grain  and 
hay  growing  as  cash  crops  replaced  the  earlier  dependence  upon  ani- 
mal products.  A  decline  in  the  productivity  of  the  soil  has  frequently 
accompanied  the  abandonment  of  animal  feeding  since  the  former 
supplies  of  stable  manure  were  no  longer  available.  Even  dairying 
is  not  at  all  universal  upon  the  Volusia  silt  loam,  owing  to  the  lack 
of  local  facilities  for  the  shipment  of  milk  or  for  its  manufacture 
into  butter  or  cheese. 

As  a  result  of  these  limitations  the  profits  derived  from  farming 
the  type  have  frequently  declined  seriously,  and  there  has  been  a 
general  decrease  in  the  rural  population  in  many  of  the  townships 
where  this  soil  is  the  dominant  type.  Scarcity  of  labor  has  resulted 
in  a  tendency  toward  the  aggregation  of  farm  lands  into  large 
holdings  accompanied  by  the  more  extensive  forms  of  cultivation 
and  a  greater  reliance  upon  farm  machinery  instead  of  hand  labor. 
The  lands  not  so  well  suited  to  this  form  of  occupation  have  re- 
verted to  pasture  and  large  areas  of  the  poorer  pastures  have  grown 
up  to  brush. 

Thus  the  topographic  and  climatic  environment  of  the  type  has 
tended  to  diminish  the  intensiveness  of  its  cultivation  and  to  restrict 
the  area  of  its  active  agricultural  occupation. 

IMPROVEMENT  IN   SOIL  EFFICIENCY. 

One  of  the  most  necessary  steps  in  the  improvement  of  the  crop- 
producing  capacity  of  the  Volusia  silt  loam  is  proper  attention  to 
the  drainage  of  the  type.  This  soil  is  fairly  well  provided  with 
natural  surface  drainage,  except  in  places  where  springs  break  out 
upon  the  hillsides  and  steeper  slopes.  Over  a  considerable  propor- 
tion of  the  type  the  subsoil  drainage  is  scarcely  adequate  for  the 
production  of  large  yields  of  any  crops  and  it  is  rarely  sufficient  to 
insure  a  growing  season  long  enough  to  mature  com  and  other  long 
seasoned  crops.  Thousands  of  areas  of  this  soil  would  be  benefited 
by  the  installation  of  frequent  tile  underdrains,  even  in  fields  which 
possess  considerable  surface  slope  and  from  which  storm  waters  flow 
away  rapidly.  The  subsoil  of  the  Volusia  silt  loam  is  a  compact, 
retentive  silt  loam,  frequently  compacted  into  a  "  hardpan  "  layer  by

continued  plowing  to  the  same  depth  or  when  the  moisture  content 
of  the  subsoil  causes  puddling  in  the  bottom  of  the  furrow.  In  all 
such  cases  the  normal  circulation  of  water  through  the  soil  and  sub- 
soil is  disturbed  and  the  soil  is  wet  and  cold  during  the  early  part 
of  the  season,  becoming  baked  and  hard  during  the  later  months  of 
summer.  It  would  be  difficult  to  remedy  this  condition  without  the 
improvement  in  the  conditions  of  underdrainage  which  may  best  be 
accomplished  by  the  use  of  tile. 

The  surface  configuration  of  the  type  is  such  as  to  afford  sufficient 
grade  for  the  tile  systems  and  outlets  are  not  difficult  of  location. 
The  chief  difficulties  to  be  encountered  lie  in  the  high  initial  cost  of 
the  tile  and  of  the  labor  for  ditch  digging  and  covering.  The  uni- 
versal presence  of  a  large  amount  of  stone  in  the  subsoil,  the  presence 
of  rock  ledges  at  shallow  depths  and  the  distance  of  the  farms  from 
points  where  tile  may  be  obtained  cheaply,  all  tend  to  make  drainage 
operations  expensive.  Yet,  upon  the  majority  of  farms,  this  im- 
provement is  the  first  essential  step  toward  increased  profits.  Tile 
drainage  should  be  undertaken,  at  least  upon  a  small  scale,  upon 
three-fourths  of  the  farms  containing  areas  of  this  soil. 

Drainage  should  be  started  by  laying  lines  along  the  natural  de- 
pressions to  carry  away  excess  moisture  which  accumulates  in  the 
spring  and  retards  the  tillage  of  the  field.  In  many  instances  a  field 
of  20  or  30  acres  may  be  greatly  improved  by  a  few  rods  of  tile  drain 
along  some  swale  or  run-off  channel  which  divides  the  field  and  inter- 
feres with  timely  cultivation  and  planting.  As  the  benefits  of  such 
drainage  are  realized  laterals  may  be  extended  into  the  body  of  the 
field.  In  all  cases  careful  surveys  should  be  made  to  establish  grades 
and  to  arrange  the  lines  of  tile  to  drain  the  largest  area  with  the 
least  expenditure  for  tile  and  labor.  Provision  should  usually  be 
made  for  the  extension  of  the  system  as  its  benefits  are  proved.  Tile 
of  less  than  3  inches  internal  diameter  should  not  usually  be  laid. 
The  depth  of  tiling,  while  dependent  upon  local  conditions,  should 
not  be  less  than  2  feet.  The  cost  per  acre  will,  of  course,  depend  upon 
the  conditions  of  the  particular  field  to  be  drained.  Experience  in 
other  areas  and  with  other  types  of  soil  show  that  fairly  good  drain- 
age may  be  secured  at  a  cost  ranging  from  $10  to  $20  an  acre. 

This  seems  to  be  a  large  item  of  expense  for  the  improvement  of  a 
soil  having  an  acreage  value  no  higher  than  the  average  of  the 
Volusia  silt  loam,  but  it  must  be  remembered  that  without  adequate 
drainage  many  of  the  other  required  improvements  upon  the  type 
can  not  be  made  at  all  and  the  majority  of  them  are  only  fully  effi- 
cient after  drainage  has  been  attended  to.  Drainage  is,  therefore, 
fundamental  to  the  profitable  occupation  of  the  Volusia  silt  loam  and 
the  agricultural  efficiency  of  this  soil  is  chiefly  dependent  upon  this 
improvement. 


THE  VOLUSIA   SILT  LOAM.  7 

In  its  present  condition  large  areas  of  the  Volusia  silt  loam  can 
not  be  made  to  grow  a  crop  of  red  clover  until  the  soil  has  been 
heavily  limed.  The  use  of  lime  is  essential  not  only  to  correct 
"  acidity  "  in  the  soil,  but  also  to  assist  in  the  proper  internal  drain- 
age of  the  surface  soil  through  its  granulating  effect  upon  the  soil 
particles.  It  also  favors  the  increase  of  the  bacteria  living  upon  the 
roots  of  the  legiuninous  crops,  such  as  clover  and  peas,  and  is  bene- 
ficial to  practically  all  crops  grown  upon  the  type.  Only  in  the  case 
of  Irish  potatoes  is  the  use  of  lime  before  the  planting  of  the  crop 
liable  to  be  harmful. 

The  greater  proportion  of  the  Volusia  silt  loam  would  be  markedly 
benefited  by  acreage  applications  of  not  less  than  one  ton  of  burned 
stone  lime,  slaked  and  applied  to  the  soil  as  it  is  being  prepared  for 
seeding  to  oats  and  the  grasses.  Instead  of  the  stone  lime,  two  or 
three  tons  of  finely  ground  limestone  or  pulverized  marl  may  be  used 
where  these  sources  of  lime  are  cheaper  in  the  equivalent  quantities 
than  the  burned  lime.  The  lime  should  be  applied  from  10  days  to 
2  weeks  before  the  seeding  of  the  land  is  attempted  and  thoroughly 
harrowed  into  the  surface  soil  to  a  depth  of  2  or  3  inches.  It  should 
be  used  once  in  a  regular  crop  rotation  of  five  or  six  years. 

The  surface  soil  of  the  Volusia  silt  loam  is  frequently  deficient  in 
organic  matter,  as  shown  by  the  pale  gray  or  ashy  color  of  plowed 
fields.  Continued  cropping  to  hay  and  grain  without  the  use  of  any 
large  amounts  of  stable  manure  has  been  largely  responsible  for  the 
present  condition  of  the  soil.  In  other  instances  the  lack  of  perfect 
drainage  and  consequent  poor  aeration  have  resulted  in  the  decay  and 
disappearance  of  the  vegetable  matter  from  the  surface  soil.  The 
restoration  of  organic  matter  is,  therefore,  one  of  the  problems  of  its 
most  effective  management.  In  extreme  cases,  where  a  run-down  field 
must  be  built  up  to  a  normal  condition,  buckwheat  may  be  sown  in 
midsummer  and  allowed  to  make  a  good  growth  until  it  comes  into 
blossom.  This  mass  of  vegetation  may  then  be  plowed  under  as  a 
very  effective  step  in  the  restoration  of  humus  to  the  soil.  It  is  a 
good  plan  to  apply  lime  to  the  soil  immediately  after  a  large  mass 
of  organic  matter  has  been  plowed  under,  especially  if  a  small-grain 
crop  is  to  be  sown. 

Winter  rye  may  be  sown  as  a  cover  crop  and  pastured  during  the 
.spring  montlis.  Later  it  may  be  plowed  under  and  a  hoed  crop — 
potatoes  or  corn —  planted.  This  method  is  effective  upon  the  steeply 
sloping  lands  where  protection  from  erosion  during  the  fall  and 
spring  is  desirable. 

No  better  method  for  maintaining  the  organic  matter  content  of  the 
Volusia  silt  loam  could  be  devised  than  the  feeding  of  the  crops  pro- 
duced and  the  restoration  of  the  stable  manure  to  the  soil.  When 
this  system  is  regularly  practiced  and  the  land  is  limed  to.  give  a 


8  ■  SOILS   OF   THE   EASTERN    UNITED   STATES. 

good  stand  of  clover,  the  organic  matter  content  in  the  surface  soil 
is  readily  maintained  or  even  increased,  especially  if  a  reasonably 
short  rotation  of  crops  is  practiced. 

Frequently  the  proper  rotation  of  crops  is  seriously  neglected,  and 
the  ordinary  succession  is  haphazard  in  the  extreme.  Some  sem- 
blance of  rotation  is  still  maintained  over  the  greater  part  of  the 
type.  Usually  sod  land  is  plowed  for  corn,  potatoes,  or  even  buck- 
wheat. The  following  year  oats  constitute  the  almost  universal 
small-grain  crop,  although  a  small  acreage  of  rye  is  grown  upon  some 
farms.  Tlie  land  is  then  seeded  to  grass  and  allowed  to  remain  in 
sod  as  long  as  anything  approaching  a  satisfactory  cut  of  hay  may 
be  secured.  This  includes  a  period  ranging  from  three  to  five  years 
or  more.  When  weeds  and  less  valuable  grasses  have  crowded  out 
the  timothy,  the  land  is  again  plowed  for  com  or  potatoes.  This 
system  results  in  a  great  preponderance  of  grass  land  and  of  tilled 
land  devoted  to  oats. 

The  crop  rotations  should  be  shortened  and  carefully  maintained 
in  regular  order  if  the  best  results  are  to  be  secured  from  the  crop- 
ping of  this  soil.  At  all  of  the  lower  elevations  and  upon  the  better- 
drained  areas  at  higher  altitudes  corn  should  be  planted  on  a  part  of 
the  acreage  devoted  to  an  intertilled  crop  and  potatoes  should  occupy 
the  rest  of  the  sod  land  plowed.  The  best  general  practice  will  be 
to  follow  the  tilled  crops  with  oats,  seeding  down  to  the  mixed 
grasses.  On  dairy  farms  or  where  other  cattle  are  fed,  a  part  of  the 
area  given  to  small  grain  should  consist  of  a  seeding  to  oats,  beard- 
less barley,  and  Canada  field  peas.  In  this  case  the  land  should 
certainly  be  limed  before  the  seeding.  The  crop  may  be  used  as 
green  feed  to  supplement  the  pastures  or  cured  for  hay  for  winter 
feeding.  A  good  stand  of  mixed  grasses  is  usually  secured  when  they 
are  seeded  with  this  combination.  It  is  practically  certain  to  follow 
the  liming  of  the  crop  upon  well-drained  land.  The  resulting  grass 
sliould  not  be  cut  for  hay  more  than  two  years,  and  the  land  should 
then  be  plowed  for  the  production  of  corn  or  potatoes. 

Another  rotation  especially  well  suited  to  farms  upon  which  only 
a  small  amount  of  live  stock  is  maintained  would  be  buckwheat,  fol- 
lowed by  potatoes,  followed  by  oats,  and  then  for  two  years  by  grass. 
The  buckwheat,  oats,  and  potatoes  constitute  sale  crops,  while  the 
hay  may  be  sold  in  part  and  in  part  used  for  feeding  the  work  stock. 
This  system  requires  an  abundant  use  of  mineral  fertilizers  with  the 
potato  crop  to  insure  the  maintenance  of  crop-producing  capacity. 

Another  requirement  of  many  thousands  of  acres  of  tJie  Volusia 
silt  loam  is  that  of  gradually  increasing  the  depth  of  plowing,  so 
that  a  portion  of  the  immediate  subsoil  may  be  reworked  into  the 
surface  soil  and  the  "  hardpan "  layer  broken  up.  Any  immediate 
increase  in  depth  of  plowing-by  more  than  an  inch  at  a  time  would 


THE  VOLUSIA   SILT  LOAM.  9 

be  liable  to  result  in  temporary  decrease  in  crop  yields.  With  each 
plowing  of  the  sod  land,  however,  the  plow  should  be  set  a  little 
deeper  until  the  total  depth  of  the  surface  soil  is  increased  to  8  or  9 
inches.  The  average  depth  of  plowing  at  present  is  not  over  4  or  5 
inches.  The  plow  should  always  be  in  good  condition,  and  the  land 
should  not  be  plowed  when  the  soil  or  subsoil  is  too  wet.  Even  if 
water  does  not  stand  in  the  furrow  the  subsoil  is  frequently  much 
compacted  by  plowing  the  soil  too  wet. 

The  Volusia  silt  loam  is  a  type  of  soil  easily  thrown  out  of  a  good 
condition  of  tilth,  but  it  may  usually  be  restored  to  satisfactoi-y 
condition  within  three  to  five  years  by  good,  careful  farming. 

LIMITATIONS  TTPON  SPECIAL  CROPS. 

The  Volusia  silt  loam  is  not  only  very  limited  in  the  character  of 
the  special  crops  which  may  be  grown  upon  it,  but  is  also  restricted 
as  to  the  general  farm  crops  to  which  it  is  best  suited. 

The  best  special  crop  for  this  soil  type  is  late  Irish  potatoes.  A 
small  acreage  of  potatoes  is  annually  grown  upon  almost  every  farm 
located  upon  the  type.  It  is  the  aim  of  the  farmer  to  grow  enough 
to  supply  his  own  needs  and  possibly  to  furnish  a  few  bushels  for 
sale.  Under  average  conditions  of  tillage  yields  are  not  large,  owing 
to  poor  seed,  faulty  preparation  of  the  land,  and  the  neglect  of  the 
growing  crop.  Under  such  conditions  of  production  the  yields  range 
from  75  to  125  bushels  per  acre.  With  modem  methods  of  manage- 
ment the  crop  is  productive  and  profitable.  In  some  portions  of 
southern  New  York  potatoes  are  grown  upon  a  commercial  scale. 
The  land  is  well  prepared,  organic  manures  and  commercial  fer- 
tilizers are  liberally  supplied,  the  crop  is  carefully  tilled  and  sprayed, 
and  yields  ranging  from  150  to  250  bushels  per  acre  are  secured.  In 
(his  region  potatoes  constitute  the  chief  sale  crop,  and  one  New  York 
county,  containing  large  areas  of  the  Volusia  silt  loam,  ranks  among 
the  leading  counties  in  potato  production  in  the  United  States. 

In  many  areas  where  the  type  has  been  encountered  it  has  been 
recognized  as  the  best  soil  for  potato  growing.  The  tubers  are  smooth 
and  of  good  cooking  quality.  Even  neglected  crops  3aeld  fair  re- 
turns. Potatoes  should  form  a  valuable  supplementary  crop  upon 
many  of  the  farms  upon  this  type  now  chiefly  given  to  dairying  or 
stock  raising. 

The  areas  of  the  Volusia  silt  loam  best  suited  to  potato  growing 
possess  effective  natural  drainage  in  both  soil  and  subsoil.  The  soil 
should  be  well  supplied  with  organic  matter  either  from  applications 
of  stable  manure  or  through  turning  under  clover  sod  or  buckwheat. 
Any  area  showing  a  pronounced  tendency  toward  a  "  hardpan  "  con- 
dition in  the  subsoil  should  he  avoided. 


10  SOILS   OP   THE   EASTERN   UNITED   STATES. 

In  addition  to  the  liberal  use  of  stable  manure,  many  growers  apply 
from  250  to  500  pounds  i^er  acre  of  some  commercial  fertilizer  high 
in  potash.  Very  few  crops  are  properly  sprayed,  and  this  practice 
should  be  extended  wherever  potato  growing  is  undertaken  upon  a 
commercial  scale. 

EXTENT  OF  OCCUPATION. 

The  entire  area  of  the  Volusia  silt  loam  has  long  been  occupied 
for  agricultural  purposes.  This  soil  was  cleared  from  its  heavy  stand 
of  mixed  hardwood  and  evergreen  trees  in  the  pioneer  days  and 
occupied  for  general  farming  purposes  and  cattle  raising.  Some 
sheep  were  kept  upon  the  majority  of  farms,  the  farm  being  divided 
between  tilled  land,  pasture,  and  considerable  stretches  of  forest. 
The  merchantable  timber  has  been  cut  from  practically  all  of  the 
type  at  present,  and  only  small  woodlots  upon  the  steeper  slopes  re- 
main. It  is  probable  that  fully  C)0  per  cent  of  the  Volusia  silt  loam 
is  at  least  nominally  under  tillage,  about  BO  per  cent  is  in  pasture, 
and  the  remainder  is  occupied  by  partially  wooded  tracts,  lying  upon 
<he  steeper  slopes. 

The  improvement  in  the  agricultural  efficiency  of  this  soil  must  take 
the  fonn  of  better  cultivation  of  the  land  now  in  farms  and  of  the 
rejuvenation  of  the  pastures  which  occupy  a  large  proportion  of  the 
rype.  Drainage,  liming,  the  restoration  of  organic  matter  to  the  soil, 
and  the  adoption  of  proper  crop  rotations  which  shall  make  use  of 
the  crops  best  adapted  to  the  type  are  the  most  essential  steps  for  its 
more  profitable  occupation.  Coupled  with  this  attention  to  the  soil, 
some  form  of  animal  husbandry,  either  dairying,  where  market 
facilities  are  favorable,  or  the  feeding  of  heei  cattle  or  sheep,  in  the 
more  remote  locations,  should  become  general. 

The  restoration  of  profitable  grasses  to  the  badly  neglected  pas- 
tures upon  the  type  is  essential  to  its  improvement.  In  many  in- 
stances the  old  pastures  must  be  plowed  before  a  profitable  reseeding 
can  be  obtained.  In  other  cases  the  cutting  of  brush,  sweet  fern 
and  other  weeds  and  the  harrowing,  liming,  and  reseeding  of  the 
pastures  will  be  sufficient  to  improve  their  conditions.  Timothy, 
redtop,  Canada  blue  grass,  and  alsike  and  red  clover  are  all  avail- 
able for  the  mixing  of  a  good  pasture  combination.  Brome  grass 
should  be  tried  alone  and  in  mixtures  for  pasturage  purposes  and 
might  be  valuable  for  mowing  lands. 

CROP    ADAPTATIONS. 

Owing  to  its  physical  characteristics,  its  high  altitude,  and  its 
northern  location,  the  Volusia  silt  loam  is  better  suited  to  hay  than 
to  any  other  farm  crops.  Fully  60  per  cent  of  the  tilled  area  of 
the  type  is  annually  devoted  to  grass  growing  for  hay  with  an  addi- 


THE  VOLUSIA   SILT  LOAM.  11 

tional  large  area  for  permanent  pasture.  Timothy  is  most  extensively 
grown  among  the  grasses.  Sometimes  alsike  clover  is  seeded  witli 
it.  Red  clover  is  little  grown  because  of  the  increasing  difficulty  in 
securing  a  good  seeding.  Without  the  liberal  use  of  lime  clover  is  an 
extremely  difficult  crop  to  grow  upon  any  large  areas  of  the  Volusia 
silt  loam.  The  yields  per  acre  of  hliy  vary  widely  in  the  different 
areas  where  the  type  has  been  encountered.  In  southern  New  York 
and  north-central  Pennsylvania  a  yield  of  1  ton  per  acre  is  about 
the  average  production  upon  this  soil.  In  these  areas  the  hay  crop 
ranges  in  yield  from  less  than  three-fourths  ton  to  more  than  1| 
tons.  The  grass  lands  are  allowed  to  remain  in  seed  for  too  long  a 
period.  As  lime  is  never  applied  and  a  top  dressing  of  stable  manure 
is  rarely  used  crops  are  necessarily  small.  In  northwestern  Penn- 
sylvania and  in  northeastern  Ohio  better  management  produces 
larger  yields  averaging  about  1^  tons  per  acre.  Even  this  production 
may  be  considerably  increased  by  attention  to  drainage,  liming,  the 
use  of  stable  manure  as  a  top  dressing  upon  the  meadows,  and  the 
shortening  of  the  crop  rotation. 

There  is  no  question  that,  rightly  managed,  the  Volusia  silt  loam  is 
an  excellent  grass  soil.  Its  fair  average  yields  persisting  under  long 
years  of  mismanagement  are  proof  of  this.  There  is  no  crop  which 
can  be  made  to  give  as  large  clear  profits  with  as  little  expenditure 
for  labor  upon  this  type  as  hay.  Even  fields  which  now  produce  too 
small  a  crop  to  pay  for  the  cutting  may  be  brought  within  three  to 
five  years'  time  into  condition  to  yield  1^  to  1^  tons  of  hay  to  ihe 
acre.  Better  treatment  will  increase  the  yields  even  above  this 
amount. 

Oats  rank  next  in  acreage  to  hay.  The  yields  range  from  25  to 
40  bushels  per  acre  with  a  general  average  for  the  type  in  the  vicinity 
of  30  bushels.  When  good  seed  is  used  the  grain  is  heavy  and  bright 
and  the  straw  of  good  quality.  Improved  seed  of  varieties  suited 
to  northern  latitudes  would  increase  these  yields. 

Buckwheat  occupies  an  acreage  nearly  equal  to  that  given  to  oats 
upon  the  Volusia  silt  loam.  It  is  not  a  common  farm  crop  in  regions 
outside  of  that  dominated  by  this  soil,  where  it  constitutes  the  main 
catch  crop  of  the  farmers.  It  is  commonly  sown  between  July  1 
and  July  10  upon  land  not  prepared  in  time  for  corn,  or  upon  which 
the  latter  crop  has  failed  to  make  a  stand.  It  matures  early  in 
September,  giving  an  average  yield  of  about  15  bushels  per  acre,  but 
with  a  range  between  12  and  25  bushels.  Midsummer  droughts  or 
early  frosts  frequently  blight  the  grain  and  care  should  be  taken  to 
see  that  only  well-drained  land  is  occupied  by  this  crop  to  give  it  an 
opportunity  to  mature  before  the  first  frosts. 

As  a  soil  renovator  buckwheat  ranks  high  in  clearing  land  from 
noxious  weeds  and  insect  pests.     It  is  frequently  sown  as  a  first  crop 


12  SOILS   OF   THE  EASTEBN   UNITED   STATES. 

upon  old  pasture  lands  which  it  is  desired  to  bring  under  tillage. 
The  grain  is  sold  for  milling  and  large  amounts  are  shipped  out  of 
the  area  for  this  purpose.  Grinding  at  local  mills,  where  these  are 
properly  equipped  to  produce  a  good  grade  of  flour,  would  give  rise 
to  the  production  of  buckwheat  middlings,  high  in  protein,  and 
admirably  suited  to  supplement  the  other  feeds  grown  for  the  dairy 
herd.  The  buckwheat  crop  is  worthy  of  more  careful  attention  in 
planning  crop  systems  for  the  Volusia  silt  loam. 

Only  a  small  acreage  of  corn  is  attempted  at  the  higher  elevations 
on  the  Volusia  silt  loam,  since  above  an  altitude  of  1,500  feet  the 
growing  season  for  the  crop  is  too  short  to  permit  the  maturing  of 
grain  in  ordinary  years,  except  upon  particularly  well-drained  land. 
At  all  elevations  com  may  be  grown  for  silage  if  the  flint  varieties 
like  the  King  Philip  or  the  Genesee  River  flint  are  planted.  At  the 
lower  elevations  occupied  by  the  Volusia  silt  loam,  in  northwestern 
Pennsylvania  and  northeastern  Ohio,  corn  constitutes  one  of  the 
crops  grown  in  regular  rotation,  both  for  grain  and  silage.  The 
yields  range  from  80  to  45  bushels  per  acre  of  grain  and  from  8^  to 
10  tons  of  silage  per  acre. 

A  small  acreage  of  Irish  potatoes  is  grown  upon  nearly  every  farm 
found  on  the  Volusia  silt  loam.  An  area  sufficient  to  produce  pota- 
toes for  home  use  and  sometimes  a  surplus  for  sale  is  planted 
each  year.  In  some  portions  of  southern  New  York  the  crop  has 
become  an  important  one  upon  a  commercial  scale.  In  the  majority 
of  areas  where  the  tj'^pe  has  been  encountered  the  special  adaptation 
of  the  Volusia  silt  loam,  under  proper  conditions  of  management,  to 
the  production  of  late  Irish  potatoes  has  been  recognized.  The  tubers 
are  usually  smooth  and  of  good  cooking  quality.  Where  modern 
methods  of  production  are  employed  the  yields  range  from  150  to  250 
bushels  per  acre.  Usually  the  crop  is  badly  neglected  and  the  general 
average  of  the  yields  outside  of  the  commercial  potato-growing  dis- 
tricts ranges  from  75  to  125  bushels  per  acre.  The  crop  should  con- 
stitute the  chief  reliance  of  the  farmers  upon  the  Volusia  silt  loam  for 
sale  as  a  money  crop  to  supplement  dairying  or  stock  raising. 

In  the  more  western  areas  of  its  occurrence  a  small  acreage  of 
winter  wheat  is  grown  upon  the  Volusia  silt  loam  giving  yields  rang- 
ing from  12  to  20  bushels  per  acre. 

Formerly  hops  were  grown  to  a  limited  extent  upon  this  type  in 
central  New  York,  but  the  crop  has  nearly  disappeared  at  present. 

Nearly  every  farm  upon  the  Volusia  silt  loam  has  a  few  apple 
trees,  planted  to  furnish  a  home  supply  of  fruit.  Frequently  these 
are  neglected  to  the  point  of  ruin,  and  very  few  apples  are  sold  from 
orchards  upon  this  type.  In  all  of  the  better-drained  areas  of  the 
Volusia  silt  loam,  particularly  in  northwestern  Pennsylvania  and  in 
northeastern    Ohio,   where   elevation   and   exposure   are   favorable, 


THE   VOLUSIA  SILT   LOAM.  13 

apples  might  be  made  a  paying  commercial  crop.  The  Northern  Spy, 
Twenty  Ounce,  and  Rhode  Island  Greening  are  fairly  well  suited 
to  production  upon  this  type  if  locations  possessing  a  depth  of  soil 
and  subsoil  of  not  less  than  4  or  5  feet  are  chosen,  with  proper 
I'egard,  also,  to  the  subsoil  drainage  and  the  selection  of  a  site  not 
unduly  exposed  to  prevalent  storm  wiuds. 

The  Volusia  silt  loam  is  best  adapted  to  the  growing  of  oats,  buck- 
wheat, potatoes,  and  hay  at  all  of  the  higher  elevations,  with  corn 
as  a  supplementary  crop,  to  be  cut  for  silage.  At  lower  elevations 
and  upon  the  best-drained  areas,  corn  may  be  grown  for  grain  pro- 
duction, and  winter  wheat  is  a  fairly  valuable  crop.  Among  the 
grasses  timothy  and  redtop  are  best  suited  to  this  soil.  Red  clover 
can  be  grown  only  with  difficulty  upon  the  greater  proportion  of  the 
iireas  of  this  type,  but  alsike  is  more  readily  seeded.  Attention  to 
the  reseeding  of  pastures  is  necessary. 

Because  of  the  high  altitudes  at  which  this  soil  is  developed,  its 
distance  from  shipping  points  and  markets,  and  particularly  because 
of  its  definite  crop  adaptations,  the  raising  of  live  stock,  includ- 
ing beef  cattle  and  sheep,  constitutes  the  best  development  of  agri- 
culture upon  it.  It  is  also  desirable  that  animal  husbandry  should 
constitute  the  chief  reliance  of  farmers  upon  this  soil  since  it  is  in 
need  of  the  restoration  of  organic  matter,  and  this  treatment  is  diffi- 
cult or  impossible  under  the  prevalent  system  of  oat  and  liay  produc- 
tion for  sale  away  from  the  farm. 

FARM    EQUIPMENT. 

The  present  farm  equipment  of  the  Volusia  silt  loam  is  too  fre- 
quently antiquated  or  defective.  This  is  especially  true  of  the  areas 
lying  at  high  altitudes  and  in  positions  rather  remote  from  principal 
highways  and  railroads.  The  dwellings  and  barns  in  the  majority 
of  cases  Avere  built  50  years  ago,  and  many  of  them  have  not  been 
kept  in  good  repair.  With  the  aggregation  of  the  lands  of  this  tyi)e 
into  larger  holdings  and  with  the  corresponding  decrease  in  rural 
population,  many  dwellings  have  been  abandoned  and  are  rapidly 
falling  into  decay.  Contrasted  with  these  local  conditions  are  areas 
in  many  localities  where  the  building  equipment  has  been  well  main- 
tained, and  many  comfortable  farm  homes  exist  upon  the  type.  In 
fact,  the  differences  between  good  equipment  and  poor  within  a  single 
township  are  frequently  veiy  noticeable. 

Nearly  all  of  the  older  homesteads,  cleared  and  equipped  in  the 
earlier  days,  are  furnished  with  a  one  and  a  half  story  dwelling  and 
one  or  several  of  the  30  x  40  foot  hay  barns  built  in  the  center  of  the 
old  hay  fields.  More  modern  equipments  include  a  good  dairy  bam 
and  sometimes  a  feeding  shed,  if  sheep  are  still  kept. 


14  SOILS   OF   THE  EASTERN   UNITED   STATES. 

In  general  the  farm  equipment  of  work  stock  and  tools  is  not 
abundant.  Small  horses  are  chiefly  used,  and  are  scarcely  adequate 
to  the  proper  tillage  of  such  a  heavy  soil.  There  is  also  a  consider- 
able variation  in  equipment  between  the  larger  and  better  farms  and 
that  of  the  more  remote  and  scarcely  profitable  holdings. 

In  certain  areas  dairying  is  the  general  form  of  farm  management 
upon  the  type.  Many  of  the  dairy  farms  are  well  equipped  with 
good  herds,  adequate  barns,  and  silos.  Milk  is  produced  for  ship- 
ment, for  the  creamery  or  cheese  factory,  or  for  home  manufacture 
into  butter.  The  herds  are  usually  either  grade  cows  of  some  of 
the  dairy  breeds,  or  else  native  stock  of  no  particular  breed.  Upon 
farms  where  some  sale  crop  is  produced  in  addition  to  the  dairy 
business,  good  profits  are  made.  Oats  for  sale,  buckwheat,  and 
potatoes  are  the  chief  crop  interests  upon  such  farms  aside  from 
the  growing  of  the  grain  and  roughage  for  the  herds.  Even  when 
no  great  profits  are  derived  from  this  system  of  farming  the  land  is 
maintained  in  better  condition,  and  a  living  income  is  derived  from 
the  capital  and  labor  invested. 

SUMMARY. 

The  Volusia  silt  loam  is  an  extensive  type  of  soil  developed  at 
the  higher  altitudes  in  the  glaciated  northern  portion  of  the  plateau 
country  which  extends  westward  along  the  New  York  and  Penn- 
sylvania line  from  the  vicinity  of  the  Delaware  River  to  the  north- 
eastern part  of  Ohio. 

The  type  lies  at  altitudes  ranging  from  approximately  900  feet 
above  sea  level  in  northeastern  Ohio  to  elevations  of  2,300  feet  in 
south-central  Xew  York. 

The  surface  drainage  of  the  type  is  fairly  well  established,  since 
the  surface  configuration  of  this  soil  is  rolling  to  hilly,  or  even 
steeply  sloping.  The  internal  drainage  of  the  subsoil  is  poor  over 
considerable  areas,  and  numerous  springs  give  rise  to  small  swampy 
areas  even  upon  some  of  the  steeper  slopes.  Tile  drainage  is  one  of 
the  chief  requisites  to  the  better  farming  of  large  areas  of  this  soil. 

The  Volusia  silt  loam  is  chiefly  devoted  to  the  production  of  grass 
for  hay  and  pasture.  Fair  yields  of  timothy  hay  are  cut,  but  there 
is  general  difficulty  experienced  in  securing  a  good  seeding  to  red 
clover.     Alsike  clover  is  fairly  successful  upon  this  soil. 

Oats  constitute  the  chief  small  grain  grown  upon  the  Volusia  silt 
loam.  Buckwheat  is  most  commonly  seeded  upon  lands  which  have 
not  been  prepared  in  time  for  the  growing  of  any  other  crop,  or  upon 
fields  which  have  been  planted  to  com  without  securing  an  adequate 
stand. 

Corn  can  be  successfully  grown  as  a  grain  crop  only  at  the  lower 
elevations  and  upon  the  best-drained  portions  of  the  type.    For 


THE  VOLUSIA   SILT   LOAM.  15 

silage  it  may  be  grown  at  higher  altitudes.  The  flint  varieties  are 
best  suited  to  production  upon  this  soil,  since  they  mature  in  a  short 
growing  season. 

Potatoes  are  generally  grown  in  small  acreage  upon  nearly  all  the 
farms  located  upon  the  Volusia  silt  loam.  In  some  areas  the  crop 
IS  grown  commercially  with  good  yields  of  smooth  tubers  of  good 
(piality.  Potatoes  constitute  one  of  the  best  money  crops  to  be 
grown  upon  this  soil  in  conjunction  with  some  form  of  animal  hus- 
bandry. 

Apples  are  chiefly  grown  in  small  home  orchards.  There  are  Imi- 
ited  opportunities  for  commercial  apple  orcharding  at  the  lower 
elevations,  where  the  total  depth  of  soil  and  subsoil  is  over  4  feet 
and  where  drainage  and  exposure  are  adequate. 

The  farm  equipment  upon  the  Volusia  silt  loam  diffei's  materially 
within  single  townships  and  in  the  different  areas  where  the  type  has 
been  encountered.  In  the  more  remote  localities  the  buildings  are 
old  and  in  poor  repair,  especially  at  the  higher  altitudes,  where  the 
decrease  in  rural  population  has  been  most  marked  within  the  past 
20  years.  Elsewhere  the  farm  equipment  is  fair  to  good.  Upon  the 
dairy  farms  the  equipment  of  buildings,  stock,  and  tools  is  usually 
better  than  upon  the  majority  of  farms  devoted  to  a  system  of  grass 
and  grain  farming  for  cash  sale.  ' 

For  its  improvement  the  Volusia  silt  loam  requires  drainage,  the 
liming  of  the  soil,  the  restoration  of  organic  matter,  the  adoption  of 
shorter  crop  rotations,  and  the  general  return  to  a  system  of  farming 
in  which  the  crops  raised  are  chiefly  fed  to  live  stock.
