The Bss horizon has hue of 5YR to 10YR, value of 4 to 6, and chroma of 2 to 4. Concretions and powdery masses of calcium carbonate range from none to 10 percent. Texture is silty clay or clay in the upper part of the subsoil with clay content of 40 to 60 percent. Texture is silty clay loam, silty clay or clay in the lower part of the subsoil with clay content of 35 to 60 percent. Calcium carbonate equivalent ranges from 20 to 40 percent in the upper subsoil but ranges to 50 percent in the lower part.
Reaction is slightly alkaline or moderately alkaline.
These are the Hollister , Indiahoma , Irion , Leeray , Lockney , Roscoe , and Teagard series. Hollister soils do not have coarse fragments of limestone in the upper part of the solum and have cooler mean annual temperature. Indiahoma soils formed in Permian age sediments, have linear shaped microhighs and have cooler mean annual temperature. Irion soils have indurated platy limestone at 60 to 80 inches. Leeray soils have SAR of 8 to more than 15 within 40 inches of the surface.
