cotton since the advent of the boil
weevil.
Iredell series consists, of, so-called
"flatwoods" With poor drainage. The
surface soil is brown O. dark gray
| with a greenish yellow plastic sticky
subsoil. The surface is practically
level and is usually somewhat lower
than the adjacent soils. The poor
drainage and plastic nature of the
subsoil makes it :. very undesirable
| soil. The texture is usually a loan
| or fine indy loan. Corn and small
grain are the main crops grown.
The Congaree series consists of
bottom soils in the Piedmont pla-
teau. The material is composed of
| wash from adjacent or upstream
upland soils, and usually is a silt
| loan or silly clay loan in texture.
These soils are very productive and
| are valuable for corn and forage
| crops where danger from overflow
| is not o great. t.s
The soils from crystalline rocks
occurring in the Blue Ridge noun
! tain section are somewhat different
! from hose derived from similar ma
terial in the Piedmont plateau owing
to the influence of climate. In this
section the Porter series is predomi-
nant. 1t is similar in appearance to
| the Cecil series o. the Piedmont pla-
| teau except in altitude and topog
raphy, which is high and more rug
| ged.
The soils in this section are used
| for forage crops and corn. Tho eli
| mate is favorable for the CONNER
| cial growing, of apples and is devel-
oping rapidly.
| In the region of sedimentary rocks
a variety of soils are developing.
The Decatur series comes from
| pure limestone and consists of
! brownish red surface soil and bright
red subsoil. The texture is usually
| a clay loan. These soils are valu-
| able for general farm crops, grasses
and alfalfa r' ,- ,."a -
The Hagerstown series is aleo de-
veloped from pure limestone, but has
brown surface soil with a red or
reddish brown subsoiI. The texture
is from fine sandy loan to a silly
loan. The crop adaptations are SIM
liar to the Decatur soils.
| The Conasauga series consists of
| soils from shale and linn stone. The
surface soil is yellowish brown silt
loan, while the subsoil is a yellow
| ish silly clay or sandy clay loan.
| This type is used for cotton, corn
| and small grain. 1t is characterized
| by rather poor drainage and a high
! line requirement
The Colbert series comes from
mixed and limestone and consists r
| fiatwoods soils having eXtr mely
moor drainage. The texture is usu-
ally silt loan or silt clay loan,
| very close and tight in structure
The topography is level. These
types are of little agricultural value
except for pastures. =
| The Christian series consists of
| reddish brown surface soils and red
subsoils developed from limestone

The Dekalb series includes noun
tain soils derived from sandstone.
They have gray surface soils and
yellowish subsoil. The texture is
predominately a sandy loan. Where
the topography is too rough they are
useful for growing corn, cotton and
: other general crops.
J. The Huntington series. is compos.
ed of alluvial material along stream
bottoms in limestone regions. The
topography is flat and the land is
! subject to overflow. The soils are
valuable for corn and forage crops
/ The soils of marine origin are pre-
dominantly sandy in texture. They
consist of material washed from the
Piedmont plateau and mountain Sec
tons and deposited in the ocean.
The Triton series consists of
brownish gray surface soils and yell
low sandy subsoils. This series is
characterized by numerous brown
iron connections from IA to inch
in diameter and is locally known as
red pebbled land. 1t is a valuable
soil for all of the general farm crops
of the section -.-
The Norfolk series is similar to
the Triton series with the exception
that it is practically free from peb-
bles. Also it has a greater variation
in texture, varying from deep sands
to sandy loans. The sandy loan
types are valuable for the general
farm crops, such as melons, truck
crops, pecans and tobacco.
The Greenville series include red
soils of the coastal plain section. The
surface soil is red to brownish red
| sandy loans to clay loan, while the
subsoil is a bright red friable soil.
1t is valuable for cotton and other
general farm crops.
Orangeburg series consists of
brown surface soils and bright red
friable sandy clay subsoil This Sc
ries is used for general farm crops,
pecans and peaches.
A consideration of some of the
special crops shows a marked pref.
erence by some of them for particu-
lar types Of soils. Peaches grow
best on the Orangeburg sandy loan
and Greenville clay, loan in. the

quality of fruit.
