Department of Geography Soil Science and Biogeochemistry

Biogeochemistry of Soils and Sediments

roots

The group focuses on biogeochemical cycling and stability of organic matter in soils and sediments by the implementation of inorganic and organic geochemical methods, including also molecular and isotope proxies. Diverse recent and past terrestrial ecosystems are under investigation and manipulative experiments improve our understanding of the influence of environmental changes on these systems.
