TYPE LOCATION: Carroll County, Kentucky; 25 yards west of
Kentucky Highway 55, 1/4 mile south of Kentucky Highway 389, about 2 miles south of Carrollton.
RANGE IN CHARACTERISTICS: The solum thickness ranges from 40 to
60 inches or more, and depth to bedrock ranges from about 60 inches to 100 inches or more. Reaction ranges from slightly acid to mildly alkaline. The weighted average of rock fragments of limestone, siltstone, sandstone, or shale range from 0 to 15 percent but individual B horizons range to 35 percent. Some pedons have a few or common black or dark brown concretions or soft concretionary-like material in some or all horizons. The mollic epipedon ranges from 10 to about 24 inches.
The A horizon has hue of 10YR, 7.5YR, or 2.5YR, value of 2 or 3,
and chroma of 2 or 3. Texture is silt loam or silty clay loam.
The Bt horizon has hue of 10YR, 7.5YR, value of 3 to 5 and chroma 2 to 4. Texture is silty clay loam, silty clay, or clay. Some pedons have transitional horizons up to 12 inches thick with the same colors of the A horizon. Texture is silty clay loam or silty clay. Some pedons have a few or common mottles in shades of gray below the upper 10 inches of the argillic horizon.
The C horizon has hue of 10YR, 7.5Y or 2.5Y, value of 3 to 5 and chroma 2 to 4. Mottles are in shades of brown, gray, and olive, or colors like those of the Bt horizon. Texture is silty clay or clay.
COMPETING SERIES: These are the Donerail, Loradale, Montello, Schapville, and Wamego series. Donerail and Loradale soils are medium or strongly acid, and their Bt horizons are not part of the mollic epipedon. Montello soils have sola less than 40 inches thick, and typically have thinner mollic epipedons. Schapville soils have sola and depth to shale of less than 40 inches. The Wamego soils have a dryer climate.
GEOGRAPHIC SETTING: Footslopes and fans with slopes of 0 to 50 percent. The soil is developed in slope alluvium or colluvium
from soils largely of limestone and shale origin. The mean
annual temperature ranges from 50 to 57 degrees F., and the mean annual precipitation ranges from 36 to 48 inches.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the
Ashton,
Boonesboro,
Cynthiana,
Fairmount,
Huntington,
Otway, and
Sees
series. Ashton soils have dark A horizons less than 10 inches
thick and less than 35 percent clay in the control section. Boonesboro and Huntington soils are on flood plains, lack argillic horizons, and have less than 35 percent clay in the control section. Cynthiana and Fairmount soils are on uplands and are less than 20 inches to bedrock. Otway soils have sola less than 40 inches thick, lack argillic horizons, and are on uplands. Sees soils have mollic epipedons 6 to 10 inches thick, and mottles with chroma of 2 or less above the upper 10 inches of the argillic horizon.
DRAINAGE AND PERMEABILITY: Well drained. Runoff is medium to
rapid, and permeability is moderately slow.
USE AND VEGETATION: Most areas are used for hay, pasture, corn,
or tobacco. Native forests have oaks, hickory, yellow poplar,
maple, ash, hackberry, and black walnut as the dominant species.
DISTRIBUTION AND EXTENT: Kentucky, Ohio, and Tennessee. Extent
is moderate.
