Abstract/Contents:Discusses the use of gypsum (CaSO4) on sports fields, stating that it "is often applied but seldom needed on Iowa sports fields. The classic misunderstanding with gypsum arises from its association with improving water movement and soil structure on sodic (high sodium) soils that are not typically found in Iowa." Explains that "gypsum is correctly used on sodic soils that have undergone a process of deflocculation. In this case, gypsum will likely improve soil structure and water infiltration." States that "the misconception arises when there is a belief that gypsum can improve structure and drainage in any heavy clay soil, even those not necessarily affected by Na+."
