Hillsdale and Oshtemo soils do not have as much clay in the argillic horizon. Metea soils have 20 to 40 inches of sand or loamy sand in the surface layer. Miami soils have free carbonates at depths of less than 40 inches. The potential for surface runoff is negligible to very high depending on slope gradient. Permeability is moderate.
Most rolling areas are in permanent pasture or forest.
