Bio-Fertilizers like Rhizobium and Azotobacter are natural, eco-friendly products that enhance soil fertility by promoting beneficial microbial activity. Rhizobium is a nitrogen-fixing bacterium that forms a symbiotic relationship with leguminous plants, helping them absorb atmospheric nitrogen for optimal growth. Azotobacter, a free-living bacterium, also fixes nitrogen in the soil, improving nutrient availability and supporting plant health. These bio-fertilizers enhance soil structure, reduce the need for chemical fertilizers, and promote sustainable farming practices. They improve root development, increase crop yields, and strengthen plant immunity against diseases. Easy to apply, Bio-Fertilizers can be used for soil inoculation, seed treatment, or foliar application. They are particularly beneficial for legumes, cereals, and vegetables. Bio-Fertilizers boost soil biodiversity by encouraging the growth of beneficial microorganisms
