Reaction is commonly moderately acid or slightly acid, but ranges to neutral in some pedons. In cultivated areas the E is commonly mixed with the Ap horizon. Some pedons have an EB or BE horizon. The Bt horizon typically is silty clay loam, but some pedons contain silt loam subhorizons. Clay content ranges from 25 to 35 percent.
Reaction ranges from moderately acid to neutral.
The BCt or BC horizon, where present, has colors in the range as defined for the Bt horizon. It is typically silt loam or less commonly silty clay loam. Clay content ranges from 25 to 35 percent. Reaction ranges from moderately acid to slightly alkaline. Redoximorphic masses of iron oxides with hue of 10YR or 7.5YR, value of 4 or 6, and chroma of 4 through 8, are present below depths of 40 inches.
