The more clayey Martin soils are on lower side slopes. The shallow Sogn and Vinland soils are on convex slopes. Surface runoff is medium. Permeability is moderate. Use is about evenly divided between cultivation and pasture.
Crops grown are small grains, sorghums, soybeans, and corn.
Pastures may be of tame or native grasses. Native vegetation is tall prairie grasses and in some areas it has scattered oak and hickory trees. The soils of this series are of moderate extent, about 42,000 acres. Shawnee County, Kansas, May 1970.
