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.
