Aberdeen soil series
A representative soil profile of Aberdeen silt loam. This soil is dark to a depth of about 85 centimeters. (Soil Survey of Spink County, South Dakota; by James B. Millar, Natural Resources Conservation Service)
The Aberdeen series consists of very deep, moderately well drained soils formed in glacial lacustrine sediments on lake plains. Permeability is slow in the solum and moderate to slow in the underlying material. Slopes range from 0 to 2 percent. Mean annual precipitation is about 19 inches, and mean annual air temperature is about 43 degrees F.
TAXONOMIC CLASS: Fine, smectitic, frigid Glossic Natrudolls
The depth to carbonates ranges from 16 to about 40 inches. Depth to accumulated salts is typically greater than 20 inches.
USE AND VEGETATION: Most areas are cropped to small grains, sunflowers, and alfalfa. Native vegetation includes western wheatgrass, green needlegrass, little bluestem, big bluestem, sideoats grama, blue grama, porcupinegrass, needleandthread, sedges, and forbs.
DISTRIBUTION AND EXTENT: Northeastern South Dakota and eastern North Dakota. The series is of moderate extent.
