TYPE LOCATION: Red River County, Texas; about 3.5 miles
south-southeast of Boxelder and 100 feet east of private road; 1.2
miles south of Boxelder on county road; 0.5 mile east and 1.0 mile
south on county road; 1.3 miles south on private road and 100 feet
east of road.
RANGE IN CHARACTERISTICS: Solum thickness ranges from 60 to more
than 80 inches.
The A horizon is very dark grayish brown (10YR 3/2), dark grayish
brown through dark yellowish brown (10YR 4/2, 4/3, 4/4), or dark
brown (7.5YR 4/3, 4/4). Mottles of very dark grayish brown (10YR
3/2), pale brown (10YR 6/3), dark brown (7.5YR 4/4), or strong
brown (7.5YR 5/6) are in some pedons. It is sandy clay loam or
clay loam and is very strongly through slightly acid. The
boundary is clear or gradual.
The B21t horizon is red (2.5YR 4/6, 4/8), yellowish red (5YR 5/6,
5/8), or reddish brown (5YR 4/4). In most pedons this horizon has
mottles of gray (10YR 6/1; 5Y 6/1), yellowish brown (10YR 5/4),
grayish brown (2.5Y 5/2), light brownish gray (10YR 6/2), brown
(10YR 5/3), or dark grayish brown (2.5Y 4/2). It contains 45 to
60 percent clay and is very strongly or strongly acid.
The B22t horizon is similar in clay content and is gray (10YR 5/1,
6/1; 5Y 5/1, 6/1), or light brownish gray (10YR 6/2), mottled with
red (2.5YR 4/6, 4/8) very dark grayish brown (2.5Y 3/2), dark
grayish brown (2.5Y 4/2), or yellowish brown (10YR 5/6). It is
medium acid throuh neutral.
The B3ca horizon is light olive brown (2.5Y 5/4, 5/6), brownish
yellow (10YR 6/6), yellowish brown (10YR 5/6, 6/8), light brownish
gray (10YR 6/4), gray (10YR 5/1, 6/1; 5Y 6/1), olive brown (2.5Y
4/4), pale olive (5Y 6/4), or olive (5Y 5/3). It is mottled in
shades of red, gray, olive, and brown and is clay or shaly clay.
It is mildly or moderately alkaline and calcareous and contains
few to common soft bodies and concretions of calcium carbonate.
The Cca horizon is light olive brown, gray, olive brown, pale
yellow, or olive and is mottled in shades of red, gray, olive, or
brown. It is clay or shaly clay and contains few or common soft
bodies and hard concretions of calcium carbonate.
COMPETING SERIES: These are the Annona, Axtell, Boswell, Colbert,
Crockett, Gore, Kipling, Normangee, Oktibbeha, Sacul, Susquehanna,
Wilcox, and Woodtell series. Annona and Woodtell soils have an
abrupt textural change between the A and Bt horizons, and in
addition, Woodtell soils are very strongly through slightly acid
throughout, including the C horizons. Axtell, Crockett, and
Normangee soils are dry in the moisture control section for longer
periods of time. In addition, Axtell and Crockett soils have an
abrupt textural change between the A and Bt horizon. Boswell,
Susquehanna, and Wilcox soils lack a zone of carbonate
accumulation in any part of the Bt horizon within a depth of 80
inches. Colbert and Oktibbeha soils have over 60 percent clay in
the control section. In addition, Oktibbeha soils have no gray
colors in the upper 10 inches of the Bt horizon. Gore soils have
mixed mineralogy. Kipling soils are somewhat poorly drained and
lack soft powdery lime in the lower solum. Sacul soils have base
saturation of less than 35 percent.
GEOGRAPHIC SETTING: Bryarly soils are on uplands. Slope
gradients are 0 to 8 percent but dominantly 1 to 5 percent. These
soils formed in calcareous clayey marine deposits. At the type
location, average annual rainfall is 45 inches, mean annual
temperature is 64 degrees F., and Thornthwaite P-E index is 78.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the competing Woodtell
series and the Deport series. Deport soils have clay textures
throughout and lack argillic horizons.
DRAINAGE AND PERMEABILITY: Moderately well drained; medium to
rapid runoff; very slow permeability.
USE AND VEGETATION: Principal use is pine, hardwood forest, and
pasture. Native forests include red oak, post oak, sweetgum,
hickory, and shortleaf and loblolly pine. Native grasses include
longleaf uniola, little bluestem, purple top, and indiangrass.
DISTRIBUTION AND EXTENT: Southern Coastal Plain of Northeast
Texas. The series is of moderate extent.
SERIES ESTABLISHED: Red River County, Texas; 1972.
REMARKS: These soils were formerly classified in the Red-Yellow
Podzolic great soil group.
