An incubation study was conducted to understand the dynamics of Zn fractions in sodic soils due to the application of amendments and zinc sulphate. Various amendments viz., gypsum @ 50 GR + green manure @ 6.25 t ha-1, green leaf manure @ 12.5 t ha-1 and press mud @ 10 t ha-1 were applied alone and in combination with ZnSO4 @ 25 kg ha-1 and zinc solubilizing bacteria. The soil was incubated for 45 days. The sampling was done after 15, 30 and 45 days of incubation and then different fractions of Zn were sequentially extracted by different extracting solutions. It is evident from the data that distribution of different fractions of Zn in soil were significantly influenced by amendments and ZnSO4 application and found in order of a water soluble + exchangeable Zn (WSEX-Zn) < organically bound Zn (OM-Zn) < amorphous sesquioxide bound Zn (AFeOX-Zn) < crystalline sesquioxide bound Zn (CFeOX-Zn) < manganese oxide bound Zn (MnOX-Zn) < residual zinc (RES-Zn) fractions. The release of WSEX-Zn, OM-Zn, CFeOX-Zn attained peak at 15 DAI and declined there after upto 45 DAI whereas the MnOX-Zn, AFeOX-Zn, RES-Zn and Total-Zn fractions increased till the end of the experiment. Based on the results, it can be concluded that the transformation of Zn is largely controlled by amendments, ZnSO4 application and zinc solubilizing bacteria due to considerable changes in the chemical and electrochemical properties of soil and thereby influence the transformation of zinc. Application of amendments significantly reduced the pH and ESP of the soil and thereby create the conducive environment for enhancing the Zn availability in sodic soils.
