Grantfork soils have a concentration of exchangeable sodium in the subsoil and contain more fine sand and coarser sand in the control section. They are on adjacent or nearby parts of the landscape. Hickory soils formed in till and contain more sand in the control section. Somewhat poorly drained. The potential for surface water runoff is medium or high.
Permeability is moderately slow.
In drained areas, depth to an intermittent apparent high water table is 0.5 foot to 2.0 feet from December to April in most years. Most areas are cropped. Corn, soybeans, milo, and small grain are the principal crops. More sloping areas are in forages for hay or pasture, or in woodland. Native vegetation is deciduous forest.
