Abstract
In India, the extents of salt affected soils are increased enormously to 6.74 million hectare. Soil salinity is one of the major problems restricting crop production in the arid and semi arid regions of the world. Area distributed in India viz., Saline soil (2.96 mha) and Sodic soil (3.78 mha) and in which the worst affected areas were found in Gujarat and Rajasthan states. These problem soils namely, saline, sodic, saline sodic soils should be managed through integrated approach for the reclamation through various practices to nullify these problems for better crop yield as well as soil fertility. Mainly we could recommend the practices of soil amendments, crop rotation, choosing of crops, soil drainage, leaching, gypsum application, lime application for reclamation of salt affected soils for sustainable development for crop production and soil fertility management.
