The discard and landfill of by-product gypsum cause significant environmental problems. About 100–280 million tons of phosphogypsum and a large amount of waste plasterboard are produced every year in the world, but the utilization rate of phosphogypsum is about 10%. Most by-product gypsum is directly landfilled or discarded without treatment, only …

Gypsum tackles soil sodicity in two ways. It has a short-term effect at the soil surface and a longer-term effect throughout the soil profile. Short-term: the salt effect. Gypsum starts working as soon as it rains. As gypsum dissolves, the salinity (ionic strength) of the soil solution increases.
