Slopes range from 0 to 5 percent. The mean annual temperature is about 48 to 53 degrees F., mean annual precipitation ranges from 30 to 42 inches, frost free days range from 130 to 180 days, and elevation ranges from 580 feet to 1530 feet above sea level. These are principally the Brems , Granby , Maumee , Morocco , Newton , and Oakville soils. The moderately well drained Brems and somewhat poorly drained Morocco soils are on slightly lower elevations in the landscape. The very poorly drained Granby, Maumee, and Newton soils are in depressions.
Oakville soils are well drained and are on higher elevations.
Moderately well drained. This soil has a seasonal high water table that ranges from 3 to 6 feet below the surface from December to April. The potential for surface runoff is negligble. Permeability is rapid or very rapid. Most areas of Denham soils are used for raising corn, soybeans and wheat.
