Calcium sulfate (or calcium sulphate) is the inorganic compound with the formula CaSO 4 and related hydrates. In the form of γ- anhydrite (the anhydrous form), it is used as a desiccant. One particular hydrate is better known as plaster of Paris, and another occurs naturally as the mineral gypsum.Gypsum Decrease Bulk Density of Soil. Gypsum-treated soil has a lower bulk density compared with untreated soil (Shainberg et al. 1989). Organics can even decrease it more when both are used.
