In this Hydrology Research Group meeting, Fotis Sgouridis (the department lab manager for those who don't know him) will give a talk on 'Denitrification and greenhouse gas emissions from natural and semi-natural terrestrial ecosystems in the UK'. For those of you who need further convincing I've attached an abstract below:

Abstract
Soil denitrification is considered the most un-constrained process in the global N cycle, hampering our ability to assess its contribution to reactive N (Nr) removal at regional to global scales. This uncertainty emanates from the difficulty in measuring in situ soil N2 production and from the high spatio-temporal variability of the process itself. This seminar will present an overview of the work undertaken, as part of the NERC Macronutrient Cycles programme, in the natural land use types (peatlands, forests and grasslands) in the Conwy and Ribble river catchments, where denitrification was measured using 15N tracing techniques in order to inform national scale terrestrial N-cycling models.
