Swerts, R. Merckx, K. Vlassak] Net productions of permanent soil atmosphere gases (N2, CO2, O2) and temporary gases (N2O, NO) were monitored in soil cores using a non-interfering, fully automated measuring technique allowing highly time resolved measurements over prolonged periods. The influence of changes in available organic carbon on CO2, N2O, NO and N2 production was studied by changing the soil carbon content through aerobic preincubations of different length, up to 21 days. The aerobic preincubation caused an increase in NO3 - concentration and a decrease in available carbon content. Available carbon content dominated both CO2 and total N gas (N2+N2O+NO) production during anaerobiosis. Both CO2 and total N gas production rates decreased with increasing length of the previous aerobic preincubation, this in spite of the higher initial NO3 - concentration. Total denitrification rates were closely related to the anaerobic CO2 production rates. No relation was found between water soluble carbon content and total denitrification. The N2O/N2 ratio could be explained by an interaction of carbon availability, NO3 - concentration and enzyme status. Net N2O consumption was monitored. The balance between cumulative total N gas production and NO3 - consumption varied according to the different treatments. Cumulative N2O production exceeded cumulative N2 production for 0 up to 5 days.
