In general composting, gypsum provides a source of sulphur that can easily be assimilated by growing plants.
One particular area of application is the production of compost for mushroom growing. The flocculating action of the calcium sulphate helps the compost to maintain an open structure, preventing it from turning sour. It also provides a buffering effect that assists the compost in staying within a pH range of around six to eight. This ensures that chemically combined nitrogen levels are maintained.
