Navratan BIO ZINC comprises of highly potent Zinc Solubilizing Bacteria ( ZSB ), which naturally supplies Zinc from soil to the plant root after solubilization of insoluble Zinc present in the soil. ZSB produce organic acids such as gluconic acid, citric acid, oxalic acid, and lactic acid.

These acids lower the pH around the root zone and dissolve insoluble zinc compounds. Zinc deficiency causes considerable yield losses and plants are subject to disease.
