Biofertilizers are substances that contain living microorganisms, such as bacteria, blue-green algae, and mycorrhizal fungi, that increase soil fertility and promote plant growth. When applied to soil, seeds, or plant surfaces, biofertilizers colonize the plant's rhizosphere and provide nutrients to the plant.
There are various uses of biofertilisers that prove their importance. They include – improving the soil quality, protecting the plants from pathogens, avoiding environmental pollution, destruction of harmful substances present in the soil, etc. Thus, biofertilisers are very important.
Biofertilizers fix atmospheric nitrogen in the soil and root nodules of legume crops and make it available to the plant. They solubilise the insoluble forms of phosphates like tricalcium, iron and aluminium phosphates into available forms. They scavenge phosphate from soil layers.
