Table 2 Cumulative amounts of CO2 respired in soils amended with MilliQ-water (CO2eCMilli-Q water) or glucose (CO2eCGlucose) during a 5 h incubation at 25 C. Theoretical additional heat dissipated from Milli-Q water (DQMilli-Q water) and glucose (DQGlucose) amended soils due to the reaction between CO2 and bicarbonate. Mean values and standard errors of four technical replicates.
