N2 - Two virtual joint centers for nitrogen agronomy were established between theUK and China to facilitate collaborative research aimed at improving nitrogenuse efficiency (NUE) in agricultural production systems and reducing losses ofreactive N to the environment. Major focus areas were improving fertilizerNUE, use of livestock manures, soil health, and policy development andknowledge exchange. Improvements to fertilizer NUE included attention toapplication rate in the context of yield potential and economic considerationsand the potential of improved practices including enhanced efficiencyfertilizers, plastic film mulching and cropping design. Improved utilization oflivestock manures requires knowledge of the available nutrient content,appropriate manure processing technologies and integrated nutrientmanagement practices. Soil carbon, acidification and biodiversity wereconsidered as important aspects of soil health. Both centers identified a rangeof potential actions that could be taken to improve N management, and theresearch conducted has highlighted the importance of developing a systems-level approach to assessing improvement in the overall efficiency of Nmanagement and avoiding unintended secondary effects from individualinterventions. Within this context, the management of fertilizer emissions andlivestock manure at the farm and regional scales appear to be particularlyimportant targets for mitigation
