The purpose of this publication is to describe the kinds of soils on the Glacial Lake Dakota Plain in Spink County. The soils of the Lake Plain are Solonetz soils, and due to the character of the subsoil, their value of irrigation is less than that of the friable associated soils which are classified as Chernozem soils. Since both Solonetz and Chernozem soils are developed from the same parent materials, and since there is some basis for relating Solonetz soil formation (solonization) to poor drainage, there is concern that irrigation may “salt out” or cause solonization to occur in the friable Chernozem soils. An understanding of the genesis of Solonetz soils can prevent this from happening and provide clues for successfully irrigation of Solonetz soil.
