The potential for surface water runoff is medium. Permeability is moderate in the solum and slow in the underlying till that contains a strongly developed paleosol. Because of the underlying paleosol, these soils have a perched water table seasonally at depths of 2 to 3.5 feet. Most areas of Harrison soils are cultivated. Corn, soybeans, and small grain are the principal crops.
Native vegetation is prairie grasses.
Harrison soils are moderately extensive. Schuyler County, Illinois, 1930. The sequence of materials for the Harrison series is Peoria loess over coarser textured Roxana silts over Illinoian till that contains a paleosol. The pedon has been described to a depth of 70 inches to show the materials that affect interpretations.
