Knute soil series

(Soil Survey of Polk County, Minnesota; by Charles T. Saari and Rodney B. Heschke, Natural Resources Conservation Service)

 

The Knute series consist of very deep, moderately well drained soils formed in calcareous loamy glacial till. These soils are typically on convex positions on ground and end moraines. The permeability is moderate. Slopes range from 0 to 3 percent. Mean annual air temperature is about 40 degrees F. Mean annual precipitation is about 22 inches.

 

TAXONOMIC CLASS: Fine-loamy, mixed, superactive, frigid Oxyaquic Argiudolls

 

Depth to the base of the argillic horizon typically ranges from 14 to 24 inches. The mollic epipedon ranges from 7 to 16 inches in thickness. The depth to the calcic horizon ranges from 16 to 30 inches. A thick solum phase is recognized where the depth to carbonates is 28 to 60 inches and the depth to the base of the argillic is more than 24 inches. Rock fragments of mixed lithology make up 2 to 10 percent by volume of the profile. The soil moisture control section is not dry in any part for as long as 45 consecutive days during the 120 days following the summer solstice. It is also not dry in any part for as long as 90 cumulative days per year in 6 out of 10 years.

 

USE AND VEGETATION: Most areas are cropped to small grain, corn, soybeans, and hay.Some areas are in woodland. Native vegetation is mixed hardwoods and prairie grasses.

 

DISTRIBUTION AND EXTENT: Northwest and West Central Minnesota. Inextensive.
