%X The bioavailability of various Ni fractions in soils was investigated employing 63 Ni tracer technique and sequential extraction procedure as well as synthetic investigation methods including partial dissolution procedure, simulated Ni forms, seedling culture, pot experiment and statistical analysis. The results showed that soluble plus exchangeable Ni was the major fraction of soil Ni available to plant. Nickel bound to carbonate and organic matter might also play some role in Ni uptake by plant. However, Fe/Mn oxide bound and residual Ni were nearly unavailable to plant(in oxidizing environment).
