Gypsum is a soft sulfate mineral compound that is composed of calcium sulfate dihydrate. Since it is water soluble, gypsum usually does not occur in the form of sand.It provides the essential nutrients calcium and sulphur but does not affect soil pH; it is neutral (pH is ~6.7). Gypsum is typically 20-22% calcium and 16-18% sulphur. The sulphur is in a plant available sulphate (SO 4) form. In addition to providing needed nutrients, the calcium in gypsum is soluble, even at a pH that is greater than 7.Gypsum comes from sedimentary rock and is formed by the evaporation of water that contains sulfates and calcium, such as saltwater.
