Theme III. Agricultural use of peat and peatlands
When natural peat soils are drained, emissions of nitrous oxide (N2O), a strong greenhouse gas, may increase considerably. Estimation of N2O emissions is challenging due to high variation in emissions and because many factors affect processes producing and consuming nitrogen and further to N2O emissions. The aim of this work is to find explanations for the high spatial and temporal variation in N2O emissions from peat soils under different land use. Biogeochemical processes in nine different study sites in Finland, Sweden and Iceland were studied with different techniques in the laboratory.
