Biofertilizer enhances soil fertility by introducing beneficial microorganisms that promote plant growth and nutrient uptake. These microorganisms, such as bacteria, fungi, and algae, fix atmospheric nitrogen, solubilize phosphorus, and enhance the availability of other essential nutrients. By fostering symbiotic relationships with plants, biofertilizers contribute to sustainable agriculture practices and reduce reliance on chemical fertilizers. Farmers increasingly adopt biofertilizers due to their eco-friendly nature and potential to improve soil health over the long term.
