The BE and Bt horizons have hue of 10YR, value of 5 to 7 and chroma of 1 to 6, and has redox depletions. Texture is silt loam or silty clay loam, and averages 20 to 32 percent clay and 4 to 10 percent sand. Reaction is strongly acid or very strongly acid. The 2Bt and 2Btx horizons have hue of 10YR or 7.5YR, value of 5 to 7 and chroma of 4 to 8, and has redox depletions. Texture is silt loam or silty clay loam, and averages 24 to 32 percent clay and 8 to 15 percent sand.
Reaction is strongly acid or very strongly acid.
The 3Btb horizon has hue 10YR or 7.5YR, value of 5 to 7 and chroma of 4 to 8 and has redox depletions. Texture is silty clay, clay, or their gravelly and very gravelly analogues. The clay content averages from 40 to 75 percent and sand content from 4 to 10 percent. Reaction is very strongly acid to moderately acid in the upper part and ranges to neutral in the lower part. The Hatfield series which average less than 40 percent clay in the lower part of the series control section.
