Role

The biogeochemical dependence of soil NOx emissions means they vary nonlinearly with region-specific agricultural management, soil conditions, and meteorology. These relationships are not currently well represented in models due in part to a lack of data capable of constraining the representation of complex soil nitrification and denitrification processes. This project aims to use existing and new data in combination with novel measurement techniques and extensive experiments to advance our process-based understanding of these complex processes. The successful applicant will use existing models of soil biogeochemical processes with existing data investigating the biogeochemical controls on reactive nitrogen emissions from agricultural soils, across a range of wheat varieties and nitrogen amendment treatments, to identify critical model failures. The model failures identified will then direct targeted experiments at the Warwick Crop Centre, including NOx isot...
