They formed in 20 to 40 inches of a loamy mantle and clayey residuum over channery or cobbly soft limestone or siltstone. Mean annual temperature is about 45 to 52 degrees F, and mean annual precipitation is about 28 to 33 inches. The Mottland and Rossfield soils are associated in similar upland positions but have mollic epipedons. These soils are well drained. They have moderate permeability in the solum and moderately rapid permeability in the underlying material.
Surface runoff is medium.
Commonly used for cultivated crops. Some areas are in woods and some are used for pasture. Native vegetation was principally oak. The soils are inextensive in southeastern Minnesota and possibly in northern Iowa. Mower County, Minnesota, 1986.
