Gypsum is calcium sulfate. The most common form of it is the dihydrate which means that each molecule of calcium sulfate has two water molecules associated with it. It is expressed as Ca(SO4)2(H20). The other form called gypsum anhydrite has no water. Regular use of gypsum is essential to the sustainability of most irrigated soils.
