13CO2 released global activity15N2O, 15N2 nitrification / denitrification activity
C and N flow trough the soil food web components : labelling experiment
Follow the fate of added 15N and 13C in the plant-soil system and quantify the impact of drought and management on the C and N flow through soil food web
