Evaluation of organic amendments to remediate a trace element-polluted mine soil. Trace element mobility was reduced in the order: MSWC > OPSW > peat > leonardite. Microbial functionality was enhanced in the order: peat ≥ MSWC > OPSW > leonardite. Trace element immobilization levels about 75% were achieved at a MSWC dose of 5%. Mine soil microbial respiration and dehydrogenase activity were greatly enhanced at a MSWC dose of 5%.
