Recent research has suggest that the utility of gypsum may extend to a greater range of soils and crops than previously acknowledged.1.1 Introduction. Gypsiferous soils are soils that contain sufficient quantities of gypsum (calcium sulphate) to interfere with plant growth. Soils with gypsum of pedogenic origin are found in regions with ustic, xeric and aridic moisture regimes (Nettleton et al. 1982). They are well represented in dry areas where sources for the calcium sulphate exist.Gypsum is a sulfate mineral that exists at variable contents of top soils, particularly those in arid and semiarid areas of the world.
