It takes several growing seasons to regain back the soil. However, studies have revealed that adding gypsum to soils didn’t show any effect on the pH, fertility, and permanent structure of the soil, yet you can still benefit from it if you have compacted soils or soils with calcium deficits or high-levels of sodium. Before you consider applying gypsum as a soil remedy, a soil analysis must be conducted first.
