BINNSVILLE SERIES
The Binnsville series consists of well drained soils that formed mainly in material weathered from the Selma Chalk Formation of the Cretaceous Period. Permeability is slow. These are very gently sloping to steep soils on uplands in the Blackland Prairie. Slopes range from 1 to 17 percent.
TAXONOMIC CLASS: Clayey, carbonatic, thermic, shallow Typic Haprendolls
TYPICAL PEDON: Binnsville silty clay loam--idle. (Colors are for moist soil unless otherwise stated.)
Ap--0 to 4 inches; very dark gray (10YR 3/1) silty clay loam; weak fine granular structure; friable; slightly sticky; many fine roots; moderately alkaline, very slightly effervescent; abrupt smooth boundary. (4 to 6 inches thick)
A--4 to 8 inches; very dark grayish brown (2.5Y 3/2) silty clay loam; moderate fine subangular blocky and granular structure; firm, sticky, plastic; common fine roots; few fine light gray soft fragments of chalk in lower part; many wormcasts; moderately alkaline, slightly effervescent; clear wavy boundary. (3 to 6 inches thick)
C--8 to 12 inches; light olive gray (5Y 6/2) silty clay loam, few distinct streaks of pale yellow (2.5Y 7/4); massive; firm, sticky, plastic; few fine roots; many wormcasts; 20 percent light gray (5Y 7/1) platy fragments of chalk; moderately alkaline, strongly effervescent; clear wavy boundary. (o to 8 inches thick)
Cr-- 12 to 48 inches; light gray (5YR 7/2) chalk; few fine splotches and streaks of yellowish brown; horizontal platy rock structure; can be dug with spade when moist; moderately alkaline, violently effervescent.
TYPE LOCATION: Clay County, Mississippi; 3.5 miles southeast of McCondy Community, or 0.25 mile northeast of State Lime Plant. NW1/4NE1/4 sec. 25, R. 4 E., T. 15 S.; lat. 33 degrees 46 minutes 20.06 seconds N. and lat. 88 degrees 51 minutes 31.97 seconds W., WGS84.
RANGE IN CHARACTERISTICS: Thickness of the soil ranges from 7 to 20 inches. The chalk of the Cr horizon has hardness of 1 or 2 on Mohs scale, and it can be dug with a spade.
The A horizon has hue of 10YR, value of 3, and chroma of 1 to 3, or it has hue of 2.5Y, value of 3, and chroma of 2, or it is neutral with value of 3, and chroma of 0. It is silty clay loam or silty clay. Some pedons contain few to common fine to coarse fragments of chalk. These and the chalk fragments in the C horizon have hardness considerably less than 3 on Mohs scale.
The C horizon has hue of 5Y or 2.5Y, value of 4 to 6, and chroma of 2 to 6, or it has hue of 10YR, value of 4 to 6, and chroma of 2. It is silty clay loam or silty clay. The C horizon contains from 10 to 30 percent by volume of chalk fragments ranging from less than 2 to 60 mm in diameter. From the surface to the top of the Cr horizon, the soil averages about 40 percent clay and the range is from 35 to 50 percent.
The Cr horizon and the chalk in the C horizon have hue of 5Y, 2.5Y, or 10YR, value of 6 or 7, and chroma of 1 or 4, or it is neutral with value of 6 or 7, and chroma of 0.
COMPETING SERIES: There are no competing series in the same family. Closely related soils are the
Demopolis,
Stephen, and
Sumter series. Demopolis soils, which do not have a mollic epipedon, are loamy-skeletal in the control section. Stephen soils have a ustic moisture regime. Sumter soils, which do not have a mollic epipedon, have a thicker solum.
GEOGRAPHIC SETTING: Binnsville soils are on erosional uplands in the Blackland Prairie. Slopes range from 1 to 17 percent. These very gently sloping to steep soils formed mainly in the weathered Selma Chalk Formation of Cretaceous age. The climate is warm and humid. Near the type location the mean annual temperature is 64 degrees F., and the mean annual precipitation is 52 inches.
GEOGRAPHICALLY ASSOCIATED SOILS: These include the
Demopolis and
Sumter soils of the competing series and the
Brooksville,
Eutaw,
Houston,
Kipling,
Okolona,
Oktibbeha,
Vaiden, and
Watsonia series. Demopolis and Sumter soils are on similar positions as the Binnsville soils, and, in places, they are in geographic mixtures that form complexes. Brooksville, Houston, and Okolona soils have a thick dark solum and are in broad, fairly large areas. Eutaw, Kipling, Oktibbeha, and Vaiden soils are more than 20 inches thick, have a Bt horizon, and are acid in reaction;
Eutaw soils are on nearly level slopes;
Kipling and
Vaiden soils are on narrow to broad areas in uplands;
Oktibbeha soils are on hillsides and ridgetops.
Watsonia soils, which do not have a
mollic epipedon, are in uplands of the Blackland
Prairie that are characterized by short, complex slopes.
DRAINAGE AND PERMEABILITY: Well drained; rapid runoff; slow permeability.
USE AND VEGETATION: Most areas of the soil are in native grasses or a sparse forest of redcedar and osageorange. Some areas are used for growing pasture and hay.
DISTRIBUTION AND EXTENT: The Blackland Prairie section of Alabama, Florida, and Mississippi. The series is of moderate extent.
