LOCATION CALEAST KYEstablished Series
TAXONOMIC CLASS: Fine, mixed, active, mesic Mollic Hapludalfs
TYPICAL PEDON: Caleast silt loam--cultivated. (Colors are for moist soil unless otherwise stated.)
Ap--0 to 7 inches; dark brown (10YR 3/3) silt loam, brown (10YR 5/3) dry; moderate fine and medium granular structure; friable; many fine roots; neutral; clear smooth boundary. (6 to 10 inches thick)
Bt1--7 to 13 inches; dark yellowish brown (10YR 4/4) silty clay; moderate fine and medium angular blocky structure; firm; many fine roots; many faint clay films; few fine (1-2 mm) black (10YR 2/1) Mn nodules; neutral; gradual smooth boundary. (0 to 10 inches thick)
Bt2--13 to 23 inches; dark yellowish brown (10YR 4/4) silty clay; moderate fine and medium angular blocky structure; very firm; common fine roots; many faint clay films; few fine (1-2 mm) black (10YR 2/1) Mn nodules; slightly acid; gradual smooth boundary. (5 to 20 inches thick)
Bt3--23 to 54 inches; yellowish brown (10YR 5/4) clay; common medium faint light yellowish brown (2.5Y 6/4) and dark yellowish brown (10YR 4/4) lithochromic mottles; moderate fine and medium angular blocky structure; very firm; few fine roots; many faint clay films; few fine (1-2 mm) black (10YR 2/1) Mn nodules; common black (10YR 2/1) Mangans on faces of peds; slightly acid. (10 to 35 inches thick)
R--54 inches; limestone interbedded with thin strata of calcareous shale and siltstone.
TYPE LOCATION: Madison County, Kentucky; about 4.7 miles southwest of Richmond and 1.5 miles west of Caleast, thence 0.1 mile north on farm road on ridgetop, and 175 yards east in pasture field.
RANGE IN CHARACTERISTICS: Depth to limestone bedrock is 40 to more than 80 inches. Solum thickness is 40 to 60 inches. reaction ranges from moderately to mildly alkaline. Fragments of limestone range from 0 to 5 percent by volume.
The A horizon has hue of 7.5YR to 2.5Y, value of 3, and chroma of 2 to 4. Value dry is less than 6. Texture is silt loam or silty clay loam.
Some pedons have thin BE or BA horizons up to 8 inches thick with colors and textures similar to the upper Bt.
The upper part of the Bt horizon has hue of 7.5YR to 2.5Y, value of 4 or 5, and chroma of 3 to 6. Texture is silty clay loam or silty clay.
The lower part of the Bt horizon has similar colors, but commonly has lithochromic mottles in shades of brown, yellow or gray. Texture is silty clay or clay.
A BC or C horizon with textures similar to the lower Bt is in some pedons. It is commonly variegated without dominant hue or chroma and includes chroma of 2 or less.
COMPETING SERIES: These are the Belpre, Brooke, Fleming, McAfee and Salvisa series in the same family. Belpre soils have redder colors in the argillic horizon and lack Mn nodules. Brooke, McAfee and Salvisa soils are moderately deep to bedrock. Fleming soils have paralithic contact and redder colors in the argillic horizon.
GEOGRAPHIC SETTING: Caleast soils are on upland ridgetops and side slopes. Slopes range from 2 to 20 percent and some areas are karst. The soils formed in clayey residuum weathered from limestone interbedded with thin layers of shale and siltstone. The average annual temperature is about 54 degrees F., and average annual precipitation is about 45 inches.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Cynthiana, Lowell, Fairmount, Faywood, and Lowell, Maury, Salvisa and Shelbyville series. Cynthiana, Faywood, Lowell, Maury and Salvisa soils do not have mollic epipedons. Shelbyville soils are fine-silty. Cynthiana and Fairmount soils are shallow. Faywood and Salvisa soils are moderately deep.
DRAINAGE AND PERMEABILITY: Well drained with moderately slow permeability. Runoff is medium on slopes less than 5 percent and high on slopes greater than 5 percent.
USE AND VEGETATION: Nearly all areas are used for growing hay, corn, tobacco, and small grains or as pasture. Native vegetation is chiefly hardwoods interspersed with grassy glades. The dominant tree species are oaks, black walnut, hickory, ash, hackberry, elm and maple.
DISTRIBUTION AND EXTENT: The Bluegrass region of Kentucky and possibly southwestern Ohio. Total extent probably is moderate.
