The overuse of chemical fertilisers has devastating effects on agricultural systems and the environment.Thus, environmentally friendly substitutes for chemical fertilisers are needed.The potential contribution of biofertilizer to food security and environmentally sound practises has increased its profile in the agricultural sector.Soil fertility may be improved by the use of biofertilizers, which contain microorganisms like fungus, bacteria, and protozoa that can fix nitrogen, dissolve phosphorus, and sequester iron.Biofertilizers are made up of microorganisms that are both living and dormant and supply nutrients for plant development.Nitrogen-fixing microbes, phosphorus-mobilising and phosphorussolubilizing microbes, potassium-solubilizing microbes, blue-green algae, and azolla were just some of the biofertilizers discussed in this review, along with their applications in crop production, production processes, and examples of helpful microbes used in biofertilizer industries. HIGHLIGHTSm Biofertilizers are eco-friendly contain living microorganisms are nitrogen fixer, phosphate solubilizers and mobilizes, plant growth promoting bacteria, etc. m Biofertilizers play an image role in agricultural sustainability.
