Chicago-The Gypsoil Division of Beneficial Reuse Management LLC now has agreements with Southern Illinois Power Cooperative and Archer Daniels Midlands to market gypsum produced as a byproduct at these companies’ operating plants for use by growers as a source of calcium and to improve soil fertility and structure. The product, marketed as Gypsoil brand gypsum, comes from Southern Illinois’ coal-fired utility plant at Marion, Ill., and Archer Daniels’ citric acid plant at Southport, N.C. “Gypsoil is an excellent option for supplying calcium, a nutrient that is important to a wide variety of crops, but particularly essential for peanut growers,” says Ron Chamberlain, Gypsoil’s director of gypsum programs. Gypsoil is used by Midwestern agricultural producers to loosen tight clay soils. Over time, Chamberlain noted, Gypsoil neutralizes the metals and chemical salts that bind to clay particles and cause poor soil structure.
