These soils can be treated with gypsum or other Ca-containing amendments to reduce dispersion and restore friable conditions. Gypsum is widely used on the alkali soils of the Western United States, but these conditions are not typically found in Wisconsin.This practice applies where land application of gypsum products will be used to alter the physical and/or chemical characteristics of soil to help achieve one of the above purposes. To remediate sodic soils, use Conservation Practice Standard (CPS) Code 610, Salinity and Sodic Soil Management.
