The moderately well drained Catlin and Dana soils are on adjacent moraines. Proctor soils are on similar nearby parts of the landscape where the mantle of loess is thinner. The somewhat poorly drained Brenton and Elburn soils and the poorly drained Drummer and Thorp soils are on lower parts of the landscape. Elburn and Drummer soils form a drainage sequence with Plano soils in areas underlain by loamy outwash. Plano soils are well drained The potential for surface runoff is low or medium.
Permeability is moderate in the solum and moderate to moderately rapid in the underlying material.
Most areas of Plano soils are cultivated. Corn and soybeans are the principal crops. Native vegetation is prairie grasses. Kendall County, Illinois, 1941.
