Our Research


Video 2 - Hochleistungsorganismus Boden

Based on long-term ecosystem research, soil ecology and ecological theory we are working on sustainable solutions for a healthy environment. Main research areas are prospective environmental hazard assessment, interactions between primary producers and soil animals and their impact on carbon cycling. At present, major research topics involve projects on the impact of engineered nanomaterials on the environment and the application of biochar for improving soil fertility and soil health. Additionally, emphasis is given on critical assessment of standardised testing procedures for assessing environmental effects of nanomaterials.

27.04.2023: Campus Award
Henry Spencer Badet IV was one of the nominees for the "Campus Award". The "Campus Preis - Forschen für nachhaltige Zukunft" is awarded by the university's trust foundation "Kellner & Stoll Stiftung für Klima und Umwelt". Spencer (Picture: in white shirt in the middle) had completed his Master Thesis on "Soil properties and microbial activity in three different farming systems on gleysols in northwestern Germany" in our group in 2022.

09.02.2023: Warburg!
Another long-term project was finished today: the showcase with our oldtimer, the Warburg apparatus dating back from the first years of the university. Former technician Ute Uebers came to help with the details, and from now on the instrument decorates the entrance of the UFT building.

01.09.2022: Today Dr. Borbála Szabo from the Institute of Ecology and Botany at the Centre for Ecological Research in Budapest, Hungary, joined our group. In the next two years she will study "Extreme climate events modifying the effects of pesticides on Folsomia candida (Collembola)" - a research fellowship financed by the Alexander von Humboldt foundation and ideally complementing our ongoing research. Good success, and a very warm welcome!
