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 *** focus areas were improving fertilizer NUE,use of livestock manures,soil health,and policy development and knowledge *** 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 *** utilization of livestock manures requires knowledge of the available nutrient content,appropriate manure processing technologies and integrated nutrient management *** carbon,acidification and biodiversity were considered as important aspects of soil *** 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 systemslevel approach to assessing improvement in the overall efficiency of N management and avoiding unintended secondary effects from individual *** this context,the management of fertilizer emissions and livestock manure at the farm and regional scales appear to be particularly important targets for mitigation.
