Forschungsschwerpunkt

Soil microbial communities and their functional traits are the key for understanding nutrient cycling in soils and the fate of pollutants in our environment. It is therefore important to investigate the distribution of microbes and their activities on different spatial scales. While nutrient accessability drive carbon turnover in microbial hotspots such as the rhizosphere and detritusphere, soil properties highly determine microbial performance on the field scale.

Upscaling of microbial turnover processes, however, is still a challenge in soil microbial ecology. In my current project 'ProScale' I am interested in predicting microbial activities and pesticide degradation potential in arable soils on the field scale using proximal and remote sensing techniques, e.g. multispectral imaging from UAVs.

ProScale is part of the FACE project ('Fate and management of chemicals in ecosystems') within the Integration Platform Tapping Nature's Potential.
