•Straw is quickly decomposed and increases CO2 emissions and only to a lesser N2O emissions.•Straw-N is released only in marginal amounts as N2O from soil.•Straw amendment and N addition to wet soil (80% WHC) triggers extensive release of N2O. The sustainable production of bioenergy from crops like...
