Azotobacter-9%SC is a liquid biofertilizer containing
Azotobacter bacteria, which are free-living, nitrogen-fixing microbes. The "9%SC" in the name likely indicates the concentration of the bacteria in a suspension concentrate (SC) formulation. This eco-friendly product is used in agriculture to enrich the soil naturally, reduce dependency on chemical fertilizers, and improve crop growth and yield. How it works
Azotobacter bacteria function as "living fertilizer factories" in the soil by carrying out several beneficial processes.
- Nitrogen fixation: Their primary function is to capture atmospheric nitrogen (N₂) and convert it into a usable form, such as ammonium (NH₄⁺), that plants can easily absorb through their roots.
- Production of growth-promoting hormones: They produce and secrete vital plant growth regulators (phytohormones), such as auxins, gibberellins, and cytokinins. These substances help stimulate root development, improve seed germination, and promote overall plant growth.
- Mineral solubilization: The bacteria can help solubilize other soil minerals, such as phosphorus, making them more accessible for plant uptake.
- Disease resistance: Some strains produce antibiotic substances that can inhibit the growth of certain plant pathogenic fungi and bacteria in the root zone.
- Soil health improvement: They aid in the decomposition of organic matter and help bind soil particles together. This improves soil structure, aeration, and water-holding capacity.
Benefits of using Azotobacter-9%SC
- Increased crop yield: Many studies and reports indicate that using Azotobacter can lead to higher yields in non-leguminous crops like wheat, rice, maize, and vegetables.
- Reduced need for chemical fertilizers: By providing a natural source of nitrogen, this biofertilizer helps decrease the application of synthetic nitrogen fertilizers like urea, resulting in cost savings for farmers.
- Eco-friendly: It supports sustainable and organic farming practices by reducing chemical runoff and promoting a healthier soil ecosystem.
- Enhanced plant health: Besides increasing nutrient uptake, it improves overall plant health and helps plants tolerate environmental stresses like drought and salinity.
Application methods
Azotobacter-9%SC can be applied in several ways, and the liquid formulation ensures quick and uniform distribution.
- Seed treatment: Seeds are coated with a diluted slurry of the biofertilizer before sowing. This ensures the bacteria are present in the root zone from the very beginning.
- Soil application: The product can be mixed with well-decomposed organic manure or vermicompost and broadcasted across the field before or during planting.
- Drip or flood irrigation: For large-scale farming, it can be diluted in water and applied directly to the soil through irrigation systems.
- Timing: For best results, it should be applied during the early morning or late afternoon to protect the live bacteria from direct UV sunlight. The soil should be moist but not waterlogged for optimal bacterial activity.
