(Combined thickness of the Bg horizon is 10 to 24 inches thick)
2Cg--32 to 35 inches; 25 percent dark gray (5Y 4/1), 25 percent olive brown (2.5Y 4/4), 25 percent strong brown (7.5YR 5/6), and 25 percent gray (10YR 5/1) clay; massive; very firm; common yellowish brown (10YR 5/8) and black (10YR 2/1) iron and manganese concretions; approximately 15 percent by volume fragments of chert; slightly alkaline. (0 to 12 inches thick)
2R--35 inches hard limestone rock.
TYPE LOCATION: Rutherford County, Tennessee; 2 1/2 miles northeast of Fosterville; 1,000 feet west of Short Creek; 300 feet south of gravel road. USGS Quad: (unknown); latitude: (unknown); longitude (unknown).
RANGE IN CHARACTERISTICS: Depth to bedrock ranges from 20 to 40 inches. Reaction is moderately acid to slightly alkaline. Fragments range from 0 to 15 percent throughout. The mollic epipedon ranges from 10 to 24 inches in thickness.
The Ap and A horizon, and the AB or BA horizons, where present, have hue of 10YR, 2.5Y, or 5Y, value of 2 or 3, and chroma of 1 or 2. Texture is silt loam, silty clay loam, or silty clay in the Ap, A, and AB horizons, and is clay, silty clay, or silty clay loam in the BA horizon.
The Bg horizon and BCg or CBg horizons, where present, have hue of 10YR, 2.5Y, or 5Y, value of 4 or 5, and chroma of 2 or less. Redoximorphic features are few to common in shades of brown, black, and gray. Texture is silty clay, clay, or rarely silty clay loam.
The Cg or 2Cg horizon has the same range in colors and textures as the Bg horizon or is an evenly mottled pattern and lacks a dominant color.
COMPETING SERIES: The Pitco series is the only other series in the same family. Pitco soils are from a climate with less than 7 mean annual precipitation and they are greater than 60 inches to hard bedrock.
GEOGRAPHIC SETTING: Eagleville soils are on flood plains.. Slopes range from 0 to 3 percent. These soils formed in clayey alluvium. Near the type location the mean annual temperature is 58.1 degrees F. and the mean annual precipitation is 53.1 inches.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Egam, Dilton, Godwin, and Roellen soils on flood plains and the Capshaw, Gladeville, and Talbott soils on uplands and terraces. Egam and Godwin soils have mollic epipedons more than 24 inches thick. Dilton soils have bedrock at less than 20 inches deep. Roellen soils have bedrock deeper than 40 inches. Capshaw soils are on terraces and have argillic horizons and do not have a mollic epipedon. Gladeville soils, on uplands, have solum thickness of less than 12 inches. Talbott soils, also on uplands, have argillic horizons and do not have a mollic epipedon.
DRAINAGE AND PERMEABILITY: Somewhat poorly drained; negligible runoff; and slow to very slow permeability. The soils are subject to flooding and ponding and the water table commonly is within 12 to 18 inches of the surface during winter and spring.
USE AND VEGETATION: About 75 percent is used for crops and pasture. Crops include corn, grain sorghum, soybeans, and hay. Native hardwoods including oak, hickory, elm, maple, sycamore, and ash; also much of these areas were in canebrakes in places.
DISTRIBUTION AND EXTENT: The Nashville Basin of Tennessee.. The series is of small extent.
