Crop and Soil Sciences

Research Interests I am interested to advance our general understanding of biogeochemical cycles of carbon and nutrient elements in soil, providing important insight into regional and global element cycles such as the carbon or sulfur cycle. This field of research has global and local relevance with implications for climate change and environmental pollution. The strong background in the chemistry, biology and physics of soils and its cycles provide the basis for the development of intelligent solutions for sustainable soil and land use management. The most exciting examples include the discovery of stabilization mechanisms of organic matter in soil nano-structures and the development of a biochar soil management technology that improves soil fertility, sequesters carbon and reduces off-site pollution. Recent efforts include the combination of bio-energy and biochar applications to soil, which offer the opportunity to develop a carbon-negative energy technology which at the same time improves the environment.
