TYPE LOCATION: Casey County, Kentucky; about 3 miles southwest of Liberty, Ky; 1/2 mile south of Pricetown; 500 yards west of U.S. Hwy 127; 10 yards north of farm road; Latitude 37-16-36N, Longitude 084-57- 51W.
RANGE IN CHARACTERISTICS: Thickness of the solum and depth to bedrock is more than 60 inches. Reaction ranges from very strongly to neutral in the Ap and BA horizons,very strongly acid to medium acid in the Bt horizon, and is very strongly acid or strongly acid in the 2Bt horizon. Rock fragments are mostly gravel size chert and range from 0 to about 5 percent in the Ap, BA, and Bt horizons, and from 0 to 35 percent in the 2Bt horizon.
The Ap horizon has hue of 10YR, value of 4 or 5, and chroma of 3 to 6. It is silt loam.
The BA horizon has hue of 10YR, value of 5, and chroma of 4 to 6. It is silt loam.
The Bt horizon has hue of 7.5YR or 10YR, value of 5 or 6, and chroma of 4 to 6. It is silt loam or silty clay loam.
The 2Bt horizon has hue of 2.5YR or 5YR, value of 4 or 5, and chroma of 6 to 8. Mottles are in shades of brown yellow, or red. Texture is silty clay loam, clay loam, silty clay, or clay, or the gravelly modifier.
COMPETING SERIES: The Pricetown series is the only member of this family. Soils in similar families are the Bewleyville, Crider, Mountview, and Ryker soils. The Bewleyville and Mountview soils have thermic temperature regimes. The Crider and Ryker soils have more than 35 percent base saturation.
GEOGRAPHIC SETTING: Pricetown soils are on nearly level to sloping broad ridgetops and upper side slopes. Slopes range from 0 to 12 percent. These soils formed in a silty mantle over residuum from cherty limestone.
Mean annual temperature is about 57 degrees F, and mean annual precipitation is about 51 inches.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Caneyville, Christian, Dickson, Frankstown, Frederick, Garmon, Lonewood, Sango and Teddy soils. All of the geographically associated soils are on similar landscape positions as the Pricetown soils. Caneyville soils are moderately deep and have a base saturation greater than 35 percent immediately above the lithic contact. Christian and Frederick soils are in clayey families, and have mixed mineralogy. Sango and Teddy soils have fragipans. Sango soils are in the thermic temperature regime. Garmon soils lack an argillic horizon, are moderately deep, and are in a fine-loamy family. Lonewood soils have less clay in the lower solum, are in a fine-loamy family, and lack a lithologic discontinuity.
DRAINAGE AND PERMEABILITY: Well drained. Surface runoff is slow to rapid and permeability is moderate.
USE AND VEGETATION: Most areas are cultivated. Principal crops are corn, soybeans, tobacco, small grains, hay, and pasture. Native forest was red, white and black oaks; hickories, gums, and maples.
DISTRIBUTION AND EXTENT: Pennyroyal of Kentucky. Extent is moderate.

SERIES PROPOSED: Casey County, Kentucky; 1988. Source of name is a small community in Casey County.
REMARKS: Pricetown soils were mostly mapped as mesic taxajuncts to Mountview soils in the past. Diagnostic horizons recognized in this pedon are:
Ochric epipedon: 0 to 7 inches (Ap horizon)
Argillic horizon: 13 to 70 inches (Bt1, Bt2, 2Bt3, 2Bt4, 2Bt5, 2Bt6)
