| Abstract: |
| Phenols, a part of soil organic matter, play important roles in soil organic matter turnover, greenhouse gas emissions and soil nutrient supply. This study investigated the contents of phenols, ammonium, nitrate, total nitrogen and organic matter in fifteen soils under different land uses in Hubei Province. Phenol contents in different soils ranged from 45.64 mg C·kg-1 to 198.48 mg C·kg-1（expressed as carbon content）, with order of vegetable soils>paddy soils>upland soils>woodland soils. Soil texture and pH influenced phenol contents. Phenol accumulated in soils was positively correlated with soil ammonium nitrogen, total nitrogen and organic matter, but negatively with soil sand contents. Our research implies that soil phenols may affect soil nitrogen transformation and mitigate soil organic matter mineralization. |
