An incubation experiment was conducted at ADAC & RI, Trichy, to study the effect of ZnSO4, chelated Zn and Zn enriched organics on dynamics of Zn in sodic soil at different incubation period. The organics viz., FYM, press mud, poultry manure and vermicompost were enriched (10:1 ratio) with ZnSO4 @ 37.5 kg ha-1 (recommended dose for hybrid maize). The ZnSO4, chelated Zn and Zn enriched organics were added @ 37.5 kg ZnSO4 ha-1 . Incubated soil sample were analysed for Zn fractions viz.
