Abstract

A literature review on quantitative relationships between environmental factors and nitrous oxide (N2O) emissions. Consequently, a database was constructed of measured N2O fluxes from natural ecosystems in temperate and boreal climate, combined with measurements or estimates of influencing variables, i.e. pH, clay content, bulk density, organic carbon content, C/N ratio, mean temperature, mean precipitation, fraction of months with temperatures below zero, N deposition, vegetation class and parent material. All fluxes were natural emissions measured in the field. The result was a database with 162 records from field measurements in natural soils in the temperate and boreal climate zones. Results of regressions analysis showed that only 15-25% of the variation in measured N2O emissions was explained by these environmental factors. Depending on the type of data used (only measured environmental factors or also estimated values) N deposition, temperature and vegetation class were among the most influential factors
