Transformation of zinc (Zn) in calcareous vertisol under submergence was carried out at Agriculture College, Dharwad during 2007 under laboratory conditions. Stubbles + ZnSO4/ZnEDTA, stubbles + FYM, stubbles + ZnSO4/ZnEDTA + FYM  and stubbles were four different treatments imposed for the study. Treatments were replicated five times and laid out in completely randomized design. Results showed  that water soluble + exchangeable Zn values were found to decrease during initial period of incubation (0-30 days) but later increased in all the treatments (30-90 days) and higher values were recorded in stubbles +ZnSO4 / ZnEDTA + FYM. Organically complexed, manganese oxide bound and amorphous sesquioxide bound zinc values increased in all the treatments at 30 days and subsequently decreased. Crystalline bound zinc values were found to decrease (0-90 days) in all the treatments except in ZnSO4 / ZnEDTA + FYM. Residual and total zinc values were found to increase in all the treatments at 30, 60 and 90 days of incubation.
