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.
