Modern agriculture's overuse of chemical fertilisers and pesticides has sparked worries about human safety, soil health deterioration, and environmental destruction. An environmentally friendly substitute that increases crop yields while maintaining soil fertility and lowering pollution is offered by biopesticides and biofertilizers. Their varieties, modes of operation, benefits, drawbacks, and possible contribution to sustainable farming are all covered in this essay. These bio-based solutions have the potential to contribute to the development of a robust and sustainable agriculture system as awareness and technology grow.
