Fundamental research activities of the Rhizosphere Ecology & Biogeochemistry Group are focussed on exploring plant rhizosphere and soil processes, with emphasis on root growth, root activities and their interaction with soil and microbial processes from the molecular to the field scale. Emphasis is put on the development of new tools and applications for root exudate sampling (e.g. exudate collectors), high-resolution chemical imaging (e.g. LA-ICPMS, planar optodes) of biogeochemical processes in rhizosphere soils, and flux measurements of nutrients and pollutants using diffusive gradients in thin films (DGT). Applied research addresses some of the most crucial global challenges such as food security and safety, global warming and soil degradation by developing enhanced soil and rhizosphere management approaches for sustainable agriculture, soil protection and remediation. Currently, emphasis is given to improving bioavailability and nutrient use efficiency in the plant rhizosphere. Similarly, novel techniques of rhizosphere manipulation for pollutant management in agriculture and phytoremediation are developed and tested at various scales.
