Bio fertilizers are organic fertilizers that are live microbial inoculants comprising bacteria, algae, or fungus that supplement the bioavailability of nutrients to plants and sometimes in combination. Biofertilizers are becoming increasingly significant in agriculture, particularly in light of growing chemical fertiliser costs as well as their possibly detrimental effects on soil health. Soil enrichment is accomplished utilising biofertilizers, both of which are long-term sustainable. They are also environmentally friendly and do not represent a harm to the environment, so they should be used in place of chemical fertilisers. The author discusses the role of biofertilizer in farming in this work. Biofertilizers have developed as a powerful compared to chemical fertilisers today due to its environmentally, easy-to-apply, non-toxic, and cost-effective properties. They also serve as a complement to agrochemicals by allowing plants to use nutrients found in soils or even in the environment.
