- Abstract:
- This project will investigate the amount of, and spatial and temporal variation in, N2O coming from a fertilised agricultural system, in drain water and in surface waters fed by the field drains. The purpose is to determine the seasonal flux of N2O leaving the soil by this route, the relationship between mineral N concentrations and N2O production and emission, and the relative contributions of nitrification and denitrification processes in soil and sediment/water to the production. Results will be upscaled to catchment, regional and national scales. Much of the fieldwork will be on an already intensively monitored MLURI site; flux chambers, water sampling and tracer techniques will be used. Laboratory work will include studies with sediment cores and flumes, investigating effect of turbulence on rate of N2O production and rate of emission from the water surface.
