The Science Behind Nitrogen-Fixing Biofertilizers
Nitrogen-fixing biofertilizers are critical for enhancing soil fertility and reducing dependency on chemical nitrogen fertilizers. These biofertilizers convert atmospheric nitrogen into forms usable by plants. Key types include:
1. Rhizobium: Forms symbiotic relationships with legume roots.
2. Azotobacter: Free-living nitrogen-fixing bacteria suitable for various crops.
3. Azospirillum: Improves root development in cereal crops.
Benefits of using nitrogen-fixing biofertilizers include reduced fertilizer costs, improved soil structure, and sustainable crop yields.
