WebZinc bearing minerals can dissolve and supply zinc to the soil solution. Once in the soil solution, zinc can be immobilized, taken up by plants, retained by soil particles, or chelated with soluble organic matter. Organic matter containing zinc must undergo mineralization before it becomes available for plant uptake. WebAs soil pH falls, Zn solubility and uptake increase and potential for phytotoxicity increases. When plant leaves reach about 300–1000 mg Zn/kg DW (typical phytotoxic level is 500 mg/kg DW in diagnostic leaves), yield is reduced. At least in acidic soils, phytotoxicity is indicated by Zn-induced Fe-deficiency-chlorosis.
