These are the Nenno and Theresa soils. The somewhat poorly drained Nenno soils form a drainage sequence on gentle gradients with the Hochheim soils. Where the loess mantle is thicker, Theresa soils are common associates in less sloping areas. Well drained and moderately well drained. Surface runoff is rapid to medium.
Permeability is moderate or moderately slow.
Native vegetation was principally maple-basswood forest. The Hochheim soils are extensive. Dodge County, Wisconsin, June 1970. Laboratory data from two pedons indicates a dry bulk density of 1.8 to 1.9 in the C horizon within depths of 40 inches.
