Biofertilizers play a crucial role in sustainable paddy cultivation by enhancing soil fertility and reducing reliance on chemical fertilizers. Nitrogen-fixing biofertilizers like Azospirillum, Azotobacter, and Blue-Green Algae improve nitrogen availability, boosting yields by 10-30%. Phosphorus and potassium solubilizers, such as Pseudomonas and Bacillus mucilaginosus, convert locked nutrients into plant-available forms, increasing productivity by up to 50%. Organic matter decomposers like Trichoderma accelerate nutrient cycling and improve soil health. Applied through seed treatment, root dipping, or soil mixing, biofertilizers offer eco-friendly solutions for higher yields, cost savings, and environmental protection. Their adoption supports sustainable rice farming for future generations.
