Abstract
Agricultural soils are accounting for 10-12% of total global greenhouse gas emissions. Nitrous oxide (N2O) is the major contributing gas accounting for 60% of global agricultural emissions. In the Netherlands, the Western fen meadow system is an area with large N2O emissions and large uncertainties in the N2O emission estimates. The area consists of cultivated peat soils. The main land use is grassland, which is intensively managed by dairy farmers. Large sources of N2O emission in this area are manure application, fertilizer application, cattle grazing and peat oxidation. The objectives of this research are to:
- identify the effects of spatial variability of N2O emission driving factors on N2O emission for the Dutch fen meadow system,
- identify the effects of small-scale temporal variability of driving factors on the annual N2O emission for the Dutch fen meadow system,
- make a detailed uncertainty analysis for the emissions of N2O at the landscape level,
- make future predictions of N2O emissions in different socio-economic scenarios.
