There is a great pressure on agricultural lands and other natural resources to produce more foods. The excess use of chemical fertilizers in agriculture makes the food production better but at the same time it deteriorates the environment and causes negative impacts on living beings. Complete dependence on chemical fertilizers for future agricultural growth causes water contamination and the quality of the soil is lost. The term ‘biofertilizer’ refers to a formulation containing living microorganisms which helps in improving the soil fertility, enhances nutrient uptake and increases crop yield by fixing atmospheric nitrogen, phosphorus and potassium solubilization, production of phytohormones, production of antibiotics and protection from biotic and abiotic stresses. Due to multiple advantages of biofertilizer, it is widely used in sustainable agriculture. It is cost-effective and eco-friendly in nature. The implementation of biofertilizers is considered to overcome the problems associated with chemical fertilizers, therefore research into widespread use of biofertilizers is one of the mainstreams in scientific work for the development of sustainable agriculture.
