The group ‘Soil Science and Soil Ecology’ of Prof. Wulf Amelung is part of the Institute of Crop Science and Resource Conservation (INRES) of the University of Bonn. A main research focus of the group is to elucidate the biogeochemistry of soil under different land-use practices and its effects on the fate and bioavailability of priority pollutants as well as on nutrient and carbon turnover in soil. Therefore, we use a wide range of analytical methods, including classical methods of soil science but also state-of-the-art techniques like on the go sensor application (e.g. mobile MIR and gamma spectrometry), mass spectrometry (LC-/GC-MS/MS-systems) and stable isotope tracing (EA/GC-c-IRMS). Our research group is involved in several German- and Europe -wide research projects and programs and is also active in Africa, Asia and South America.
