Soil carbon and greenhouse gas exchange
In our work with soil carbon and greenhouse gases we apply (1) field measurements of greenhouse gas exchange and DOC fluxes, (2) analysis of large-scale trends in soil carbon stocks, and (3) modeling.
Measurements of greenhouse gas exchange and DOC fluxes
Measurements of carbon dioxide, methane, nitrous oxide and dissolved organic carbon (DOC) are made within several different projects. We study for example effects of tree-stump harvest and soil scarification on the soil carbon budget, or effects of ditches in peat soils on fluxes of carbon dioxide, methane and nitrous oxide.
Analysis of large-scale trends in soil carbon stocks
The Swedish Forest Soil Inventory is an important tool for our work. We sample approximately 2000 sites each year and measure, among many other things, carbon and nitrogen content. These data are used for the official national reporting of greenhouse gases from the land use sector to the UN climate convention and the Kyoto protocol. We also make own scientific analyses and collaborate with other scientists who need soil data.
Modeling
We use several different computer models to simulate carbon and greenhouse gas fluxes. Modeling is made to increase the understanding of processes and to upscale and analyze consequences of changes in for example land use.
