Nodine and Southridge soils are on similar positions but Nodine soils have a loamy 2B horizon and Southridge soils have a thicker loess mantle. Seaton soils are typically upslope where the loess mantle is thicker. Runoff is medium to very rapid. Permeability is slow. Corn, small grain, and legume hay are the principal crops on the less sloping area.
Steeper areas are in pasture or woodland.
