Thickness of the horizons having moist value and chroma of less than 3.5 is 20 to 58 inches. The A horizons have hue of 5YR, 7.5YR or 10YR, value of 3 to 5, and chroma of 2 or 3. The A horizons are silty clay, clay, or clay loam. Concretions and powdery masses range from less than 1 percent to about 5 percent by volume. Depth to carbonates ranges from 10 to 26 inches.
Texture is silty clay loam, clay loam, silty clay, or clay.
Calcium carbonate equivalent ranges from 15 to 30 percent. Visible calcium carbonate in the form of concretions, pebbles or powdery masses range from 5 to 20 percent. There are no competing series in the same family. Similar soils are the Garvin , Knippa , Krum , Lewisville , Matoy , and Rowena series. Garvin soils are moist in the soil moisture control section for longer periods, contain exchangeable sodium within the control section, and have an irregular decrease in organic matter with depth.
