Agriculture has an enormous environmental footprint. One of the best ways to mitigate climate change is to create balanced food systems based on sustainable agriculture. To reduce the chemical dependence scientists are engineering crop plants for N 2 fixation and they are focused on the biological process BNF (Biological Nitrogen Fixation) for the needs of N2 for crop plant soils. N2 fixed by the BNF process reduces the production cost, Green House gas (GHG) emissions, pollution of surface and ground water. Several management practices are there which influence BNF process in agricultural system. They are N- fertilization species genotype and cultivar and seeding ratios. Better management practices can help to improve N2 fixation. This review highlights the agro-economic importance of BNF and shows it as a cost effective, non- polluting way to improve the soil fertility and crop production.
