The upper part of the argillic horizon is typically part of the mollic epipedon. Reaction is slightly acid through slightly alkaline. Texture is clay loam, loam, silt loam, or silty clay loam with 18 to 35 percent clay and more than 15 but less than 35 percent fine or coarser sand. Carbonates range from 2 to 8 percent. EC is 0 to 4 mmhos.
Reaction is slightly or moderately alkaline.
Texture is loam, clay loam, or sandy clay loam. Carbonates range from 4 to 15 percent when averaged. Inconsistent accumulations of carbonates may exceed 15 percent but are discontinuous throughout the pedon. EC is 0 to 4 mmhos. Reaction is moderately or strongly alkaline.
