Solubilization of Insoluble Zinc Compounds by Gluconacetobacter diazotrophicus and its Influence on Maize

Zinc deficiency was created in maize seedlings in the sand culture and deficiency was rectified with the addition of insoluble zinc sources and G. diazotrophicus. The basic strategy behind this approach is decreasing the pH and making zinc soluble and as a consequence, the available zinc will get increased in the soil system. Since lowering of soil pH to 5 or below increases the Zn solubility. The plant growth, chlorophyll content and plant zinc content were found to be enhanced due to inoculation of G. diazotrophicus with insoluble zinc compounds.
