A look below ground: soil and cycles
Main menu
Forests can only provide ecosystem services like clean water, pure air and nutrients for plants when the soil is healthy. We examine how external factors like pollutants, climate change and land management affect the functions and biogeochemical cycles in the soils of near-natural ecosystems.
External influences such as pollution, rising temperatures and human interventions alter the water and nutrient cycle and therefore the growth conditions for roots and microorganisms in the soil. The composition of the soil community also changes as a result. Managing woods using heavy forestry machinery, for example, consequently has an impact on soil fertility.
We investigate these interactions through field and laboratory experiments and long-term monitoring projects. With the findings, we are able to draw conclusions on the living conditions encountered by trees, their roots and soil organisms – both now and in the future – in forest soils and other uncultivated soils as well as the networks in which they are linked.
