Clay content averages from 27 to 35 percent in the particle-size control section but ranges from 20 to 40 percent in individual subhorizons of the argillic. Volume of gravel ranges from 3 to 15 percent throughout. Volume of cobbles ranges from 0 to 5 percent throughout. Reaction naturally is moderately acid or slightly acid in the surface layer and upper subsoil but ranges to slightly alkaline, where the soil is limed. Reaction ranges from moderately acid to slightly alkaline in the lower part of the subsoil and is slightly alkaline or moderately alkaline in the substratum.
Free carbonates are in the substratum and in some pedons, are in the lower part of the subsoil.
The Ap horizon has hue of 7.5YR or 10YR, value of 3 or 4, and chroma of 2 or 3. Dry value exceeds 5.5. The Ap or A horizon is fine sandy loam, loam, or silt loam. Some pedons have an E horizon with hue of 7.5YR or 10YR, value of 4 to 6, and chroma of 2 or 3. It is fine sandy loam, loam, or silt loam.
