Nitrogen-fixing bacteria fertilizers
Nitrogen-fixing bacteria fertilizers naturally fix nitrogen in the soil and provide the nitrogen needed by crops. These bacteria convert nitrogen (N₂) available in the air into ammonia (NH₃) or nitrate (NO₃⁻) that is useful for plants.
1. Free-living Nitrogen Fixing Bacteria
These bacteria live independently in the soil and fix nitrogen.
🔹 Azotobacter
Mainly useful for wheat, rice, corn, vegetables and other crops.
Along with nitrogen fixation, these bacteria improve the growth of plant roots.
🔹 Azospirillum
Useful for cereal crops (wheat, corn, sorghum, millet, sugarcane).
Produces hormones that help in root growth.
🔹 Clostridium
Anaerobic (growing without oxygen) bacteria, which fix nitrogen in agriculture.
🔹 Beijerinckia
Bacteria that work well in tropical and humid climates.
2. Symbiotic Nitrogen Fixing Bacteria
These bacteria fix nitrogen by symbiotically attaching to the roots of plants.
🔹 Rhizobium
Very useful for legume crops (e.g. tur, gram, moong, urad, soybean).
Nodules of these bacteria form on the roots and fix nitrogen.
🔹 Frankia
Symbiotically fixes nitrogen in some shrub plants (e.g. alnus, casuarina).
3. Blue-green algae (Cyanobacteria / Blue-Green Algae - BGA)
These naturally fix nitrogen in reservoirs or rice fields.
🔹 Nostoc and Anabaena
Especially useful in rice fields.
Help increase organic matter in the soil.
🔹 Tolypothrix and Oscillatoria
Help fix nitrogen in wetlands.
🌱 Benefits:
✔ Reduces dependence on nitrogen-containing chemical fertilizers.
✔ Increases soil fertility.
✔ Improves the microbial cycle in the soil.
✔ Increases crop production.
✔ Suitable for environmentally friendly and sustainable agriculture.
✨ Conclusion:
Nitrogen-fixing bacterial fertilizers provide nitrogen naturally and make agriculture more sustainable. These fertilizers are very useful for organic farming and increasing production.
✅ Natural farming – rich soil, bountiful produce! 🌱🚜
