Managed agricultural ecosystems (grassland and cropland) are an important source and/or sink for greenhouse gases (GHG) as well as reactive trace gases. Due to the simultaneous influence of management activities (e.g. fertilizer application, harvest, grazing) and various environmental drivers, the flux patterns are often complex and difficult to attribute to individual drivers. Management related mitigation options may result in trade-offs between different GHG (CO2, CH4, N2O) or between emission of GHG and reactive gases like NH3.
The session addresses experimentalists and modelers working on fluxes and exchange processes on plot, field, landscape, and regional scale. It is open to a wide range of studies including the development and application of new devices, methods, and model approaches as well as field observations and process studies.
Particularly welcome are studies on the full carbon, nitrogen or GHG budgets, as well as studies comparing GHG and reactive gas exchange. We also encourage contributions about N2O, NH3 and NO emission factors.
