I take an interest in carbon and nitrogen cycling in cropping systems, with a focus on how management and systems design influence greenhouse gas emissions, nitrogen dynamics and soil carbon sequestration.
I am responsible for the course ”BI1220, Sustainable soil management in agroecosystems”, which is part of the Lantmästare program. My teaching is mainly related to soil science and climate change.
- ”Residuegas” (FORMAS-ERA-net Cofund; ERA-GAS). My part of the project includes field and incubation experiments with measurements of greenhouse gas emissions. Improved estimation and mitigation of nitrous oxide emissions and soil carbon storage from crop residues (ResidueGAS)
- ”Turning catch crops into intermediate crops for higher productivity and reduced N and P losses” (SLF). I investigate how emissions of nitrous oxide are affected by incorporation or removal of residues from an intermediate crop. Turning catch crops into intermediate crops for higher productivity and reduced N and P losses
