Role of biofertilizers in agriculture

Bio-fertilizers are eco-friendly, low-cost, and sustainable alternatives to chemical fertilizers, containing beneficial microorganisms that promote nutrient availability, enhance plant growth, and improve soil fertility.Unlike chemical fertilizers, which may cause environmental pollution and health hazards, bio-fertilizers offer an economically attractive and ecologically sound approach to agriculture.They play a vital role in biological nitrogen fixation, particularly in leguminous crops, while also benefiting intercropped and subsequent crops.As essential tools of modern organic farming, bio-fertilizers help maintain long-term soil fertility and productivity, making them especially valuable for small and marginal farmers.
