Reaction is mildly alkaline or moderately alkaline throughout. The A horizons have hue 10YR to 5YR, with value of 3 to 5, and chroma of 2 to 3. The lower part of the A horizon is usually redder than the upper part. Texture of the A horizon is clay, or silty clay. The Bw and Bk1 horizons have hue of 10YR to 5YR, with value of 4 or 5, and chroma of 2 or 6.
Texture is clay or silty clay.
Soft masses of calcium carbonate range from 0 to 10 percent by volume. Structure of the solum below the plow layer ranges from moderate to strong very fine and fine angular blocky. The Bk2 and Bk3 horizons have hue 10YR to 5YR with value of 6 or 7, and chroma of 4 to 6. The soft masses and weakly to strongly cemented concretions of calcium carbonate range from about 15 to 40 percent by volume. These include the Chatt and Rowena series and the similar Dant and Uvalde series.
