Sun Bio Rhizo (P) is a high-quality powder-based biofertilizer containing effective strains of Rhizobium bacteria formulated on a dextrose base. Rhizobium is a beneficial nitrogen-fixing microorganism that forms nodules on the roots of leguminous crops such as soybean, groundnut, chickpea, pigeon pea, black gram, and green gram. These bacteria convert atmospheric nitrogen into ammonia, which can be readily absorbed by plants, thus providing a natural and continuous source of nitrogen throughout the crop cycle.
