Abstract

Two virtual joint centers for nitrogen agronomy were established between the UK and China to facilitate collaborative research aimed at improving nitrogen use efficiency (NUE) in agricultural production systems and reducing losses of reactive N to the environment. Major focus areas were improving fertilizer NUE, use of livestock manures, soil health, and policy development and knowledge exchange. Improvements to fertilizer NUE included attention to application rate in the context of yield potential and economic considerations and the potential of improved practices including enhanced efficiency fertilizers, plastic film mulching and cropping design. Improved utilization of livestock manures requires knowledge of the available nutrient content, appropriate manure processing technologies and integrated nutrient management practices. Soil carbon, acidification and biodiversity were considered as important aspects of soil health. Both centers identified a range of potential actions that could be taken to improve N management, and the research conducted has highlighted the importance of developing a systems-level approach to assessing improvement in the overall efficiency of N management and avoiding unintended secondary effects from individual interventions. Within this context, the management of fertilizer emissions and livestock manure at the farm and regional scales appear to be particularly important targets for mitigation.

提高农业氮素利用效率的研究进展:中英氮素农学虚拟联合中心

中英两国建立了两个氮素农学虚拟联合中心，以促进旨在提高农业生产系统氮素利用效率(NUE)和减少活性氮对环境损失的合作研究。主要重点领域是提高肥料的氮肥利用效率、牲畜粪便的使用、土壤健康以及政策制定和知识交流。肥料氮肥利用效率的提高包括在产量潜力和经济考虑的背景下关注施肥率，以及改进措施的潜力，包括增效肥料、塑料薄膜覆盖和种植设计。提高牲畜粪便的利用率需要了解可用的营养成分、适当的粪便处理技术和综合营养管理做法。土壤碳、酸化和生物多样性被认为是土壤健康的重要方面。两个中心都确定了一系列可以采取的潜在行动来改善氮素管理，所进行的研究强调了开发一种系统级方法来评估氮素管理总体效率的改善和避免个人干预的意外次要影响的重要性。在这种情况下，在农场和区域范围内管理肥料排放和牲畜粪便似乎是特别重要的缓解目标。
