They have a thinner loess mantle and average more than 25 percent sand in the control section. Fishhook and Keller soils are on similar landform positions and contain more than 35 percent clay in the lower one-half of the control section, and formed partly in Sangamon paleosols. The moderately well drained Downs and Rozetta soils are on similar and more sloping landform positions. Ipava and Keomah soils are on nearby summits and form a biosequence with Emery soils. Somewhat poorly drained.
Surface runoff is medium.
Permeability is moderate. The seasonal high water table is 0.5 foot to 1.5 feet below the surface in spring. Soils are used to grow corn, soybeans, small grain, and hay. Natural vegetation is grass and deciduous hardwood forest. Central and western Illinois.
