The well drained Oakville soils and the moderately well drained Ottokee soils are on higher beach ridges and dunes or on more sloping areas. Arkport, Galen, and Spinks soils are on similar topographic positions as Oakville and Ottokee soils but have argillic horizons consisting of thin lamellae. The coarse-loamy Gilford soils are in nearby loamy deposits. Somewhat poorly drained. An apparent seasonal high water table is at 1 to 2 feet below the surface during January to April of most years.
Permeability is rapid.
The potential for surface runoff is negligible to low. Most areas are cultivated. Principal crops are corn, soybeans, and wheat. Some areas are in woodland. The native vegetation was mixed hardwoods with oak, elm, and maple the principal species.
