1.. IntroductionThe global distribution (except in Antarctica) of Vertisols and Vertic intergrades indicates that an area of 257 × 10 6 ha are confined between the 45°N and 45°S latitudes of which India occupies ∼ 30% area (Dudal, 1965).Vertisols of sub-humid, semi-arid and arid climatic regions of the Peninsular India are calcareous.
The reason why a small amount of gypsum can improve the soil is that gypsum changes the gradation of soil and the reaction between the components in gypsum and the active substances in soil.
