摘要：Present paper describes current status of biofertilizers in Indian agriculture. Biofertilizers are natural fertilizers that are microbial inoculants of bacteria, algae, fungi alone or in combination. They are defined as a product containing carrier based (solid or liquid) living microorganisms that are agriculturally useful in terms of nitrogen fixation, phosphorous solubilization or nutrient mobilization. They augment the availability of essential elements like nitrogen, potash, phosphorous, sulphur by directly supplying them or transforming them into soluble form. In addition, they also help plants to uptake several micronutrients. Types of biofertilizers viz., Rhizobium, Azospirillum, Azatobactor, blue green algae, blue green algae (BGA) inoculation, Phosphorous solubilizing biofertilizers, Mycorrhizea etc., are used predominantly in India.
