A review of Swedish crop residue statistics used in the greenhouse gas inventory

Factors for recalculating primary crops into the nitrogen content of crop residues for different arable crops are compiled and summarised here. The data is included in the calculation of nitrous oxide from the turnover in crop residues and was used in the inventory of greenhouse gases in the 2006 Submission. The data is compared to data for both Denmark and Finland. In addition, sources of uncertainty are discussed. The suggested revision decreases the estimated emissions from crop residues by 18 % in 2003. The emissions from crop residues correspond to 6 % of the N2O emissions from agriculture in this year.
