The main objective of this work was to evaluate the dynamics of CO2 and CH4 emissions from wetland soil of the sedge-grass marsh, which belongs to large complex of wet meadows near Třeboň town. CO2 and CH4 emission measurements realized on six places, where gas emission collars permanently inserted. Finally, samples of air were taking with using manual emission gas chambers within period from April 25th to November 24th 2014. The highest fluxes of CO2 were recorded in June and July. The lowest water level was recorded in this period together with low fluxes of CH4. Methane emissions were higher in September and October at the time where water level was above soil surface. Range of CO2-C fluxes was -9.38 mg m-2 h-1 (consumption) to 147.84 mg m-2 h-1 (emission). Range of CH4-C fluxes was -14.94 ?g m-2 h-1 (consumption) to 5561.67 ?g m-2 h-1(emission).
