The mollic epipedon includes the upper parts of the Bt horizon in most pedons. The depth to a consistent horizon of secondary calcium carbonates ranges from 10 to 36 inches. The depth to the base of the argillic horizon is 8 to 20 inches. Rock fragment content is 0 to 35 percent and is mainly pebbles. Reaction is neutral or mildly alkaline.
Reaction is neutral or mildly alkaline.
Btk horizons are present in some pedons and are moderately alkaline. Clay content is 18 to 35 percent silt is 15 to 35 percent, and sand content is 40 percent or more with over 30 percent being fine sand or coarser. Common textures are gravelly or non gravelly sandy loam and sandy clay loam, loam, and coarse sandy loam. Fine or coarser sand content is 35 percent or more. Calcium carbonate equivalent ranges from one to 14 percent.
