Abstract

The aims of this study were i) to determine differences in soil CO2 efflux and temperature measured at different times of day and night, ii) to assess how can the time of soil CO2 measurements bias the parameter of temperature sensitivity (Q10) of CO2 efflux, and iii) to compare seasonal sum of carbon released from soil as calculated from continuous measurement and from models based on measurements at different times. The experiment was carried out in a Norway spruce forest stand, situated in Moravian-Silesian Beskydy Mountains. Estimation of the total seasonal amount of released soil carbon based on models of individual data sets differed by as much as 7.2% from continuously measured data. The study shows that the times at which manual measurements are taken should be considered in the subsequent data processing
