In order to remove soil tetracycline residue and identify the effect of tetracycline on soil nematode community, agricultural waste returning was applied in a maize monocropping field, northeast China. The results showed that plant parasites were the dominant genera in high concentration of soil tetracycline; however, bacterivores were the dominant genera in all organic matter amendments. Maturity index, structure index and enrichment index showed the highest values in biochar and compost mixed amendments and these treatments had the highest tetracycline removal rate and the highest concentration of macro-aggregates, total organic C and available N, followed by biochar seperate amendments. Overall, biochar and compost mixed amendments efficiently reduced the risk of soil tetracycline pollution below the threshold, with the characteristics of cheap, improving soil fertility and above all, environmentally friendly.
