Nitrogen fertiliser use is essential for adequate food production, but the low efficiency of use makes agriculture the main anthropogenic source of nitrogen pollution and nitrous oxide. Enhanced efficiency fertilisers (EEFs) show promise for improving nitrogen use efficiency. However, the impact of EEFs depends on complex interactions with plant growth, soil conditions, water management, and weather. This project will assess the benefits of EEFs in major agricultural systems in Australia, pastures in NZ, and wheat-rice systems in China. Comprehensive laboratory and field trials will inform development of a soil-water-plant atmosphere model, leading to a decision support tool guiding the use of EEFs.
