SUMMARY

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.
