Reaction ranges from strongly acid to neutral. Some pedons have a BE horizon. The Bt horizon has 10YR or 7.5YR hue, value of 3 to 5, and chroma of 3 or 4 in the upper 10 inches or more and 2 to 4 in the lower part. It is silty clay loam, silty clay, or clay. The particle-size control section averages between 35 and 45 percent clay.
Reaction is neutral or slightly alkaline.
Carbonates are in the lower part of some pedons. The BC or BCt horizon has hue of 10YR or 7.5YR, value of 4 or 5, and chroma of 3 or 4. It is silty clay loam. Reaction is slightly alkaline or moderately alkaline and contains carbonates. The C horizon has 10YR or 7.5YR hue, value of 3 to 5, and chroma of 3 to 4.
