It typically is stratified. Textures include loam, sandy loam, sandy clay loam, clay loam, silt loam, and silty clay loam. Some pedons have thin strata of loamy sand. Clay content ranges from 10 to 32 percent and sand content ranges from 15 to 80 percent. Content of rock fragments is less than 15 percent.
Reaction ranges from neutral to moderately alkaline.
These are the Chalmers , Chetomba , Dolbee , Dunham , Elpaso , Elvira , Garwin , Hartsburg , Madelia , Mascoutah , Maxcreek , Maxfield , Ossian , Patton , Pella , Rushmore , Sable , and Wacousta series. Chalmers, Maxcreek and Maxfield soils are less than 40 inches to subhorizons that average more than 15 percent sand. Chetomba, Madelia, Pella, Rushmore, and Wacousta soils contain carbonates at depths less than 40 inches. Dolbee and Elvira soils formed in silty alluvial sediments on flood plains and river terraces and are subject to flooding. Dolbee soils do not have stratification and typically have less sand in the substratum than the Drummer soils.
