Brookings soil series
A representative soil profile of Brookings silt loam. There is about 65 centimeters of silt loam material over clay loam glacial till. The soil is dark to a depth of about 65 centimeters. (Soil Survey of Spink County, South Dakota; by James B. Millar, Natural Resources Conservation Service)
The Brookings series consists of very deep, moderately well drained soils formed in loess overlying glacial till on footslopes and in swales. Slopes range from 0 to 6 percent. Mean annual precipitation is about 559 millimeters (22 inches), and mean annual temperature is about 6 degrees C (43 degrees F).
TAXONOMIC CLASS: Fine-silty, mixed, superactive, frigid Pachic Hapludolls
The depth to glacial till ranges from 51 to 102 centimeters (20 to 40 inches). Thickness of the mollic epipedon ranges from 41 to 76 centimeters (16 to 30 inches) and extends into the B horizon. The depth to carbonates ranges from 51 to 97 centimeters (20 to 38 inches). Some pedons have carbonates at a shallower depth due to mixing by worm activity. A stone line 3 to 8 centimeters (1 to 3 inches) in thickness is at the glacial till contact in most pedons.
USE AND VEGETATION: Most of the Brookings soils are cultivated, the principal crops are: corn, soybeans, small grain, and alfalfa. Native vegetation typically is big bluestem, Indiangrass, switchgrass, sedges, and a variety of forbs.
DISTRIBUTION AND EXTENT: MLRA-102A. Northeastern South Dakota and southwestern Minnesota. Moderately extensive.
