This project will use synthetic organic chemistry, biochemistry, root and rhizosphere biology and rhizosphere modelling to establish detailed mechanistic knowledge of the nitrogen (N) transport and uptake processes at the soil-root interface to develop new, efficient urease and nitrification inhibitors for reliable provision of N to the plant/root system. The reduction of excessive N fertilisation has significant environmental benefits by reducing greenhouse gas emissions and water pollution. This project will lead to a breakthrough for the triple challenge of food security, environmental degradation and climate change, while improving plant productivity and increasing the profitability of agriculture through lower fertiliser costs.

本项目将利用合成有机化学、生物化学、根和根际生物学以及根际模拟，建立土壤-根界面氮素运输和吸收过程的详细机理知识，以开发新的、有效的脲酶和硝化抑制剂，为植物/根系系统提供可靠的氮素。减少过量的氮肥施用，通过减少温室气体排放和水污染，具有显著的环境效益。该项目将为应对粮食安全、环境退化和气候变化这三重挑战带来突破，同时通过降低化肥成本提高植物生产力和农业盈利能力。
