| Abstract: |
| Livestock and poultry manure as an organic fertilizer are used to resolve environmental treatment of wastes . The long-term application of manure which often contain heavy metals and antibiotics and other pollutants may pollute the soil, affect soil key process, and reduce soil quality；The article reviewed the effect of agricultural application of manure on the soil ammonia oxidation process and functional microorganism. The research progress show that: heavy metals have an inhibitory effect on the ammonia oxidation process and functional microbes, and the inhibitory degree is closely related with heavy metal species and soluble heavy metals, but no correlation with heavy metal total; The process and mechanism of antibiotic effects on soil ammonia oxidizing process and microorganisms has interspecific differences. Fluoroquinolone antibiotics inhibited ammonia oxidation at high concentrations, while tetracyclines showed opposite trend. Interaction of antibiotics and heavy metals on soil ammonia oxidation should be further studied. This review provides the reference for the evaluation and indication of the feces of livestock and poultry farm soil ecological risk. |
