Some pedons have a BC horizon. The C horizon has hue of 10YR or 2.5Y, value of 5 through 7 and 4 through 6 moist, and chroma of 2 or 3. This horizon typically is silt loam, ranging to include loam and very fine sandy loam. In places, thin wind stratification is common and includes material ranging from loam to sand. Reddish or brownish mottles are in the C horizon of some pedons, but are not related to a present water table.
Reaction is mildly alkaline or moderately alkaline.
The Graybert and Lowry series in the same family and the Cozad, Gates, Nuckolls, and Uly soils. Graybert soils are deeper to free carbonates and have buried horizons. Lowry soils are typically shallower to free carbonates. Cozad soils are stratified and formed in alluvium. Gates soils lack mollic epipedons.
