In Sweden drained cultivated organic soils contribute to a substantial part of total emissions of greenhouse gases. The aim of this study was to investigate if it is possible for the farmer to reduce the greenhouse gas emissions by choosing a specific cropping system. In this study two different crops grown on the same field were compared regarding their emissions of CO2 and CH4. A range of different organic soils with various soil properties were used. The results show that the differences in greenhouse gas emissions are greater between sites than between crops. The conclusion in this study is that it is not possible to mitigate the greenhouse gas emission from drained organic soils by changing the cultivated crop.
