The two water molecules are structurally bound to the calcium sulfate, giving gypsum its characteristic hydrated form. 2. Gypsum Helps Reclaim Sodic Soils. Gypsum is used in the reclamation of sodic soils (Aldrich and Schoonover 1951). Where the exchangeable sodium percentage (ESP) of sodic soils is too high, it must be decreased for soil improvement and better crop growth. The most economical way is to add gypsum which supplies calcium.Both lime and gypsum are easily applied using lawn spreaders. Lime can burn a lawn if misapplied, but gypsum will not.
