For elimination of the temperature dependency of CO2 efflux, standardized CO2 efflux R10 is used. Mean R10 was about 2.50, 5.0 and 0.97 umolCO2 m-2 s-1 for grassland, forest soil and stems. In grassland the R10 course did not show obvious trend. Whereas in the forest soil, the significant increase in R10 at the beginning and decrease at the end of the season occurred, but without any distinct maximum. Similar increase and decrease in R10 was observed in the stem CO2 efflux course as well. But there was a maximum in June and July. The temperature CO2 efflux sensitivity (Q10) was 3.04, 1.90 and 2.25 for the grassland, forest soil and stems. The temperature sensitivity in the forest soil increased shortly after rain. It resulted in a rapid increase in CO2 efflux of the soil as a response to rain.
