Tag Nano NPK is a unique consortium of NPK bio-inoculants such as rhizobium, acetobacter, phosphobacteria, and potash solubilizing bio-fertilizer. This microbial blend synthesizes macro-nutrients – atmospheric nitrogen, solubilizes phosphorous, and mobilizes potassium into an easily absorbable form, thereby enhancing nutrition to crops. The individual inoculants used in the consortia have their specific roles to play, namely – The Azotobacter chroococcum bacteria present in Tag Nano NPK fix molecular nitrogen from the atmosphere and releases it in the form of ammonium ions into the soil & make it available to the plants. Bacillus megaterium grows in the rhizosphere and secrete organic acids, which dissolve unavailable phosphate into a soluble form and make it available to the plants. This PSB strain enables the plants to endure drought. Frateuria aurantia produces organic acids and enzymes that help solubilize the fixed potassium into exchangeable form and make it assumable by plants.
