Long term exhaustive cropping practice and indiscriminate use of poor quality water can result in accumulation of salts and sodium that adversely affect crop growth. Salinity and sodicity are the major soil degradation issues primarily in arid and semi-arid regions of the world. The sustainability of agriculture is a matter of deep concern due to widespread removal of nutrients in excess of their application resulting in depletion of major soil nutrient reserves. Nitrogen (N) use efficiency of applied N in saline and sodic soils is low.
