Elco soils are moderately well drained and are on similar landform positions. The moderately well drained Winfield, the well drained Rozetta and Fayette soils, and the somewhat poorly drained Keomah soils formed entirely in loess and are upslope on higher backslopes and shoulders or on crests of summits. The somewhat poorly drained Keller soils have a mollic epipedon, are in biosequence with Fishhook soils, and are on similar landform positions. Somewhat poorly drained. The potential for surface runoff is low to medium.
Permeability is moderate in the loess and slow in the till.
The seasonal high water table is 1.0 foot to 2.0 feet below the surface in spring during normal years. Many areas are used for cultivated crops. Corn, soybeans, and small grain are the principal crops. Other areas are used for forage, hay, pasture, or woodland. Native vegetation is hardwood forest.
