The fractions of metals remediated (%) by varying ratios of com-post and soil mixtures are shown in Fig. 2. A similar trend of metal removal was observed in the two treatments i.e., bioremediation with ‘compost-only’ and ‘compost + plant ’. The remediation ability of the treatment with compost and plant effectively removed greater percentage of metals than the ‘compost-only’ treatment.In ‘compost + plant ’ treatment, higher fractions of Mn (31%), Fe(49%), Cu (51%) and Zn (31%) were removed than in ‘ compost-only ’treatment. An exception is that, Cr showed a higher removal rate(64%) in ‘compost-only’ treated soil than in ‘compost + plant ’ treatment.
