At the Chair of Soil Ecology, we work on the interactions between plants, soil organisms and the abiotic components of soils, especially in forests. In research and teaching, we deal with soil science fundamentals as well as application-oriented issues that arise from changing environmental conditions for the soil ecosystem and have consequences for the sustainable management of soils and soil protection.

Soil of the year

2025: Rendzina

On the annual World Soil Day, December 5, the Soil of the Year for the following year is presented at a ceremony. The “Soil of the Year” committee of the German Soil Science Society (DBG) and the German Soil Association (BVB) make the selection.

Rendzina was named Soil of the Year 2025 on December 5, 2024 at the Mecklenburg-Vorpommern State Representation in Berlin. Rendzina has developed from limestone, dolomite or gypsum rock and forms a dark-colored, highly revitalized topsoil through the accumulation of humus.

Forestry Conference 2025

FoWiTa 2025
29.09. – 02.10.2025
Freiburg

Current and future social and ecological challenges make it imperative for us to ‘Rethink the forest’ – the title and motto of the Forestry Science Conference 2025, which will take place from 29th September 2025 to 2nd October 2025 in Freiburg im Breisgau.
We aim to foster a scientific dialogue on the future of forests, not only within the field of forestry science but also across forestry practice, politics, and the public sphere. We seek to incorporate the ongoing discussions in these areas. In this context, we also plan to address the forest strategies of both federal and state governments and discuss them in light of current research findings. To achieve this, we invite you to submit ideas for events and encourage you to propose innovative formats aligned with our motto.

Research Group ForestFloor

Functionality, Dynamics and Vulnerability in Change (DFG FOR 5315)

Forest floors can store large quantities of CO2, they nourish special biotic communities and can have a decisive influence on the vitality and stability of forests. The influence of climate change on this soil layer, which is central to forest soils and extremely sensitive to environmental changes, is being investigated by this international research group.

Cluster of Excellence Initiative “Future Forests”

The adaptation of complex social-ecological systems to global change is the subject of a Cluster of Excellence Initiative at the German Research Foundation. The aim of the cluster initiative is to develop, analyse and evaluate transformation pathways towards resilient forest-based social-ecological systems, their governance, management and use. The head of the Chair, Fritzi Lang, is one of the co-spokespersons of the cluster initiative.
