The poorly drained Drummer and somewhat poorly drained Elburn soils are on lower parts of the landform nearby. Warsaw soils have a strongly contrasting particle-size class and are on similar parts of the landform nearby. The potential for surface runoff is low or medium. Permeability is moderate to moderately rapid in the solum and very rapid in the substratum. Corn, soybeans, small grain, and grass-legume mixtures are the common crops.
Native vegetation is prairie grasses.
Extent is moderate. Kendall County, Illinois, 1973. This revision contains a new typical pedon. The former pedon had redoximorphic features at a depth of 25 inches.
