Abstract Nitrous oxide (N2O) emissions from agricultural soils are influenced by several factors, including fertilizer and water management. A 4-year study (2012–15) was conducted to evaluate the impact of different types of fertilizer and water table management systems on N2O emissions under a corn-soybean rotation. The types of fertilizers assessed were inorganic fertilizer (IF) and a combination of inorganic fertilizer and solid cattle manure (SCM) (applied in 2012 and 2014, for corn only), while the water table management systems were regular tile drainage (DR), and controlled drainage with sub-irrigation (CDS). The IF and SCM were combined with DR and CDS in separate plots arranged as a two by two factorial design. The results show that, in 2012, 2013 and 2014, N2O fluxes were significantly (2012, 2013 p

玉米-大豆轮作下肥料和地下水位管理对一氧化二氮排放的影响

摘要 农业土壤中的一氧化二氮 (N2O) 排放受多种因素的影响，包括肥料和水管理。进行了一项为期 4 年的研究（2012-15 年），以评估不同类型的肥料和地下水位管理系统对玉米 - 大豆轮作下 N2O 排放的影响。评估的肥料类型是无机肥料 (IF) 和无机肥料和固体牛粪的组合 (SCM)（2012 年和 2014 年应用，仅适用于玉米），而地下水位管理系统是常规瓷砖排水 (DR)，和辅助灌溉 (CDS) 控制排水。IF 和 SCM 与 DR 和 CDS 结合在单独的图中，排列为二乘二因子设计。结果表明，2012、2013 和 2014 年，N2O 通量显着（2012、2013 p
