These are the Carmi , Longlois , and Rodman soils. The well drained Carmi soils have dark colored surface layers 10 or more inches thick and are on less sloping areas in the landscape. The well drained Longlois soils average more than 18 percent clay in the particle size control section and are on less sloping ridge tops. The excessively drained Rodman soils are on more sloping areas. Runoff is medium on sloping areas and rapid on strongly sloping areas.
Permeability is moderately rapid in the subsoil and very rapid in the underlying material.
Most areas are used to grow corn, soybeans, or small grain. A few areas are used for hay or pasture. Native vegetation is a mixture of tall prairie grasses and deciduous trees. The Desker series is of small extent. Tippecanoe County, Indiana 1993.
