The waterlogged and saline soils are found all over the country. About 9.03 M ha of land is affected by salinity and alkalinity problem in India. Due to improper management of water in agriculture, the area under problematic soils increasing every decade. Inorder to meet food security of nation on sustained basis, both salt affected soils and waters need to be managed using appropriate techniques. These techniques employ mechanical, chemical and bio-control measures. Bio-control measures involve selection of more salt-tolerant crops, residue management, and bio-drainage. Sugar beet, sugar cane, dates, cotton and barley are among the most salt tolerant crops. Crop residues left on the soil surface reduce evaporation. Thus, less salt will accumulate towards soil surface and thereby managing salinity. The bio-drainage concept is based on utilizing the consumptive water use of plants with aim to remove excess groundwater through the process of transpiration by salt tolerant vegetation and thereby reducing problem of salinity. This is achieved by enhancing the transpiration capacity of the area by introducing high-water use vegetation in large areas to maintain groundwater balances below the root zone of the crops. Therefore, bio-control could be utilized to manage soil and water salinity for sustainable agriculture.
