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.
