To evaluate the effect of organic wastes on the PAHs removal efficiency of plant-microbe remediation system, the contaminated agricultural soils were amended with different dosages of sewage sludge (SS) and cattle manure (CM) in the presence of alfalfa (Medicago sativa L.) and PAHs-degrader (Bacillus sp. and Flavobacterium sp.).
