Methane is a potent greenhouse gas and does not only account for up to 17% of global warming but also is a key target in climate change mitigation actions. Agricultural soils have always been regarded as a very weak sink or a source of methane. However, recent research by the Bodelier group has shown that under laboratory conditions, these soils are capable of (circum-)atmospheric methane uptake after the application of bio-based residues - especially compost. The mechanisms of this residue-stimulated uptake of methane are as yet unknown and are the subject of this project. The project focuses to a large degree on compost and the microbes in there, which seems to be partly responsible for the observed stimulation. We cooperate closely with a number of companies and aim at product development (e.g. engineered compost) for contributing to more climate-friendly agricultural soils.
