Abstract

Abstract: Poultry manure, which contains abundant water‐soluble organic matter (WSOM), is commonly applied in plastic greenhouse vegetable production. There is little research on whether WSOM stimulates nitrous oxide (N2 O) emission after poultry manure application. A 30 day incubation experiment and a field experiment are conducted to investigate the response of the N2 O flux after poultry manure or WSOM inputs. The cumulative N2 O emissions from soil amended with WSOM in the incubation experiment are two to four times than those from unamended soil. Similarly, in the field experiment, the N2 O emissions significantly increased by 225% (to 1.13 kg N ha −1 ) after poultry manure and irrigation application compared to a control during summer fallow season, accounting for ≈20% of the annual N2 O emissions from plastic greenhouse vegetable production. In conclusion, WSOM in poultry manure increases N2 O emissions from plastic greenhouse soil during its initial application; moreover, N2 O emissions during summer fallow season should be included in the N2 O emission inventory of plastic greenhouse vegetable production. Measures for controlling N2 O emissions such as avoiding nitrate accumulation and improving water and poultry manure management should be adopted in plastic greenhouse vegetable production. Abstract : N2 O emissions are evaluated after adding poultry manure with high water‐soluble organic matter. Extremely higher N2 O emissions are measured for the greenhouse soil with nitrate accumulated compared to cropland soil. The N2 O emissions after adding manure during the summer fallow are suggested to be included in N2 O inventory of greenhouse system.
