Impacts of fertilization optimization on N loss from paddy fields: Observations and DNDC modeling case study in Shanghai, China
Soil and Tillage Research(2020)
摘要
•N loss from paddy fields was observed with embedded lysimeter system.•Surface runoffs occurred shortly after fertilization contributed largely to the total N loss.•Combination of field and modeling research effectively optimized management practices.•Fertilization optimization significantly reduced total N loss by 31.65 % in the experimental site.
