Soilorganic matterandconditioners
The SOMAC research group focuses on the physicochemical and molecular description of soil organic matter and the development of approaches for soil protection, amendment and revitalisation. It studies humic substances, biochar, lignite, hydrogels, soil conditioners and bioinoculants, as well as their interactions with soil.
The research includes the isolation, characterisation and evaluation of soil organic matter and the study of transport processes in soil, such as the sorption, diffusion and mobility of metals, pollutants and pharmaceuticals. The aim is to connect basic research with practical applications in improving soil quality, water retention, organic matter stability and nutrient availability through an interdisciplinary combination of physical, materials and environmental chemistry with microbial approaches.
