Short summary

This study focused on the modellisation of two important drivers of soil greenhouse gas emissions: soil contamination and soil moisture change. The aim was to include a Cu function in the soil biogeochemical model DNDC for different soil moisture conditions and then to estimate variation in N₂O, NO₂ or NO_x emissions. Our results show a larger effect of Cu on N₂ and N₂O emissions than on the other nitrogen species and a higher effect for the soils incubated under constant constant moisture.
