Zinc grow -Caps are capsules that contains a zinc solubilising bacteria which solubilises insoluble / fixed zinc in the soil and make it available to plants .These bacteria improve the plant growth and development by colonizing the rhizosphere and by solubilizing complex zinc compounds into simpler ones, thus making zinc available to the plants.

These bacteria improve the plant growth and development by colonizing the rhizosphere and by solubilizing complex zinc compounds into simpler ones, thus making zinc available to the plants. Zinc solubilizing microorganisms solubilize zinc through various mechanisms, one of which is acidification.
