提高土壤肥力/生产力和减少氮肥对环境的影响对可持续农业至关重要。目前还缺乏在广泛的时空尺度上量化各种施肥制度对土壤氮素储存和损失的贡献。基于1990-2009年中国3个典型农区的田间试验数据，研究了化肥、有机肥配施化肥和秸秆还田3种施肥处理下土壤氮素动态及土壤剖面（0-100 cm）氮素变化。在考虑土壤氮素变化的基础上，采用质量平衡法估算了氮素的环境损失。结果表明，有机肥还田处理显著增加了土壤氮素贮量，氮素损失量（平均为总氮输入量的20 -24%）低于其他处理（平均为35 -63%）。土壤氮素分布和质量平衡数据均表明，在中国南方降水量较高的酸性土壤中，化学施肥的淋溶风险高于其他两个地点。有机肥配施化肥不仅可以提高氮素利用率，提高土壤肥力，而且可以将氮素的流失和对环境的破坏降到最低。
Improving soil fertility/productivity and reducing environmental impact of nitrogen (N) fertilization are essential for sustainable agriculture. Quantifying the contribution of various fertilization regimes to soil N storage and loss has been lacking in a wide range of spatiotemporal scales. Based on data collected from field experiments at three typical agricultural zones in China, soil N dynamics and N changes in soil profile (0–100 cm) were examined during 1990–2009 under chemical fertilization, manure incorporation with fertilizer, and fertilizer with straw return treatments. We employed a mass balance approach to estimate the N loss to the environment after taking into account soil N change. Results showed a significant increase in soil N storage under manure incorporation treatments, accompanied with the lowest N loss (ave.20–24% of total N input) compared to all other treatments (ave.35–63%). Both soil N distribution and mass balance data suggested higher leaching risk from chemical fertilization in acidic soil of southern China with higher precipitation than the other two sites. This research concludes that manure incorporation with chemical fertilizer not only can achieve high N use efficiency and improve soil fertility, but also leads to the lowest total N loss or damage to the environment.
