Harpster soils are on similar or slightly lower parts of the landform and are calcareous throughout. Peotone soils are on similar or slightly lower positions, have mollic epipedons more than 24 inches thick, and lack carbonates within a depth of 40 inches. Wauconda soils lack mollic epipedons and are on slightly higher parts of the landscape. Runoff is slow and in some places, ponded in late winter and spring or after snow melt or periods of excessive rainfall. The apparent seasonal high water table is at 0.5 foot above the surface to 1.0 foot below the surface during spring in most years.
Permeability is moderate.
Most areas of these soils are used for cultivated crops. Corn and soybeans are the principal crops. Native vegetation is probably marsh grasses and sedges. These soils are of large extent with more than 200,000 acres mapped. Ford County, Illinois, 1929.
