Plant-Soil-Atmosphere Exchange Processes
The aim of the Research Unit “Plant-Soil-Atmosphere Exchange Processes” is the quantification of matter and isotope fluxes between plants, soil and the atmosphere and elucidation of the biogeochemical and physical processes behind them in a range of ecosystems from cropland and grassland to forest. The analytical methods used comprise a range of techniques from enzyme assays at the leaf scale, chamber and cuvette measurements, classical gas chromatography and isotope ratio mass spectrometry up to online isotope-specific laser absorption spectrometry. The ultimate goal is to contribute to constraining global greenhouse gas budgets through process-oriented research and to help to develop management strategies for greenhouse gas emission reduction. For this, basic research is complemented with application-oriented projects.
Current research foci:
Process studies on greenhouse gas exchange and N loss
Wetlands in East Africa: Reconciling future food production with environmental protection
Effect of nitrogen availability on lignin stability in soils
Instrumental and Data-driven Approaches to Source-Partitioning of Greenhouse Gas Fluxes (IDAS-GHG)
