Soil management and crop production present many problems on the irrigated farms of western South Dakota. The farmer on the clay soils has a particularly vicious set of these. That the seriousness of these problems was recognized early is evidenced by the establishment of research on the irrigated clay soils at the United States Belle Fourche Field Station in 1912. During the past 38 years much valuable information has been gained. Whether this information is yet sufficient to guide the development of a profitable and stable agriculture on the clay soils is still questionable. However, it is believed that the information gained may be of considerable help. New work on many of the more pressing unsolved problems is now underway. It is the purpose of this circular to present the more important findings3 as they apply to the irrigated clay soils of the region.
