Abstract: A study was conducted with Leucaena as the test crop to investigate the bioavailability of heavy metals (chromium and nickel) from dumpsite soil treated with manure compost. The application of manure increased number of leaves and plant biomass, compared to unamended controls. Generally, heavy metals were higher in the plant root than in the shoot. But application of manure decreased Cr concentration in the root below the control; contrarily, Ni was increased in roots of manure treated than control plants. Cr in the shoot did not differ significantly among the treatments, but increase in manure levels further decreased Ni concentration in the shoot, compared with the control plants. Metal translocation factor (TF) >1 was noted for Ni only in the control plants, but manure application decreased Ni translocation. Chromium translocation was generally <1. Bioconcentration factor (BCF) was generally <1, but higher for Ni than Cr. Hence, Leucaena might be suitable for phytoextraction of nickel, but application of manure could make Leucaena suitable for phytostabilization in a contaminated soil.
