The indiscriminant use of chemical fertilizers during past four decades for increasing the agriculture produce has affected the soil fertility. The water retaining capacity and the content of the nutrient like Sulpher, Boron and Zinc have decreased in soil. Considering this the concept of organic farming in which the biofertilizers are being used in place of chemical fertilizers is being promoted all over the world. The biofertilizers are cheap, eco-friendly, non toxic and their production is based on renewable energy sources. The use of biofertilizers improves the physical, chemical properties and fertility of the soil. The biofertilizers increase the humus contents, porosity and water holding capacity and maintain the nutritional balances in soil. These are natural fertilizers which are microbial inoculants of bacteria, algae, fungi alone or in combination. The organic manures compost, green manure, microbial inoculants such as the blue green algae and Azola, Rhizobium, Azoto bacter, Phosphate solubilifing bacteria and the Tricoderma are quite popular biofertilizers and their utility is well established.
