An important bacterium in agriculture for its role in the nitrogen cycle, Azotobacter vinelandii helps in enriching soil nitrogen content, which is vital for the growth of non-leguminous crops.
It exhibits biocontrol activity against various plant pathogens, thereby reducing disease incidence and promoting healthier plant growth.
Production of Growth-Promoting Substances
It produces growth-promoting substances such as vitamins, auxins, and gibberellins, which stimulate plant growth and development.
Nitrogen Fixation
Azotobacter vinelandii converts atmospheric nitrogen into ammonia, which is readily available for plant uptake, thereby enhancing plant growth and reducing the need for nitrogen fertilizers.
Phosphate Solubilization
Azotobacter vinelandii solubilizes insoluble phosphates in the soil, making phosphorus more accessible to plants, thereby improving their nutrient uptake and growth.
