The wheat taskforce at South Dakota State University established a 5.26 hectare (13 acre) research area in 1979 to conduct interdisciplinary research on wheat production in South Dakota. A site near Raymond, South Dakota was selected to represent the southern black glaciated plains land resource area. The nearly level to moderately sloping areas within this research area are occupied by Houdek and Prosper soils. These two soils alone represent over 15% of the area. Houdek soils occur on the uplands with Prosper soils being found in the shallow swales. These two soils dominate the wheat taskforce research site and their chemical and physical properties were further analyzed.
