Technically called calcium sulfate, gypsum is a naturally occurring mineral that contains calcium and sulfur. It can be chemically expressed as CaSO42H20. The word ‘gypsum’ originally comes from the Greek word for ‘plaster.’. Thus, pointing back to the long history of its use as a binding agent, building material and an ingredient in

Gypsum. Gypsum, or calcium sulphate (CaSO4), is a naturally occurring mineral. 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 (SO4) form.
