Reaction is slightly alkaline or moderately alkaline and contains carbonates in most pedons. Typically some part of the matrix has chroma of 1 or 2 and redoximorphic features of higher chroma. This part is stratified silt loam, loam, silty clay loam, clay loam, or sandy loam, and some pedons contain thin lenses of sand or loamy sand. Sand content averages more than 10 percent and is not dominated by fine or very fine sand. Some pedons contain as much as 20 percent coarse fragments.
Reaction is moderately alkaline, or less commonly, slightly alkaline and contains carbonates.
Chalmers, Chetomba, Drummer, Elpaso, Patton, and Sable soils do not have carbonates in the upper half of the series control section above a depth of 40 inches. Dunham soils average more than 15 percent gravel in the lower part of the series control section. Hartsburg, Mascoutah, and Sable soils average less than 10 percent sand in the lower half of the series control section. Madelia soils have in the lower half of the series control section a sand fraction dominated by very fine sand or fine sand. Maxcreek and Rushmore soils have well graded sand fractions lower two parts of the series control section.
