Zn in the soil can be found in the form of bivalent ion, the absorption complex of the soil binds it strongly.
Its solubility increases with rising H+ ion concentration; its complex forming ability is similar to that of copper. The solubility of different zinc compounds decreases with the increasing pH
Zn first of all plays important role in the function of enzymes of the intermedier metabolism
Zn in plants is necessary for triptophan synthesis. Since triptophan is the precursor of indol-acetic-acid plant growth is indirectly regulated by Zn.
