Typically, the slope range is from 2 to 18 percent but ranges from 0 to 70 percent. The Spinks soils are the well drained member of a drainage sequence that includes the somewhat poorly drained Thetford soils. They are associated with the Boyer and Oshtemo soils on lake plains or outwash plains, and Oakville or Chelsea soils on either lake plains or moraines. Dryden , Lapeer , Metea , Ottokee , and Owosso soils are on adjoining till plains or moraines. The potential for surface runoff is negligible to medium.
Permeability is moderately rapid.
Spinks soils are used mostly for hay production or pasture. Some areas are cropped to corn, wheat, oats, and soybeans. A small part is in orchards. Steeper areas are in forest or permanent pasture. The native vegetation is hardwoods, dominantly oaks and hickories.
