Soil respiration is one of most important of carbon flows between ecosystems and atmosphere.After biologic disturbances is the value of respiration increases and it contributes to the increased concentration of CO2 in atmosphere with adverse effects on climate change. We monitored soil respiration in High Tatras mountains in the research area, which is used for long-term monitoring of changes in ecological conditions in spruce ecosystems after natural disturbances in spruce ecosystems after natural disturbances. We evaluated soil respiration using three independent methods:1. portable analyzer with closable chamber (EGM4, PPSystems) 2. automatic design of its own design with IRGA sensor Vaisala GMP343 and 3. tower measurement of CO2 flows "eddy covariance". Base of the measurements was, that we determined the average hourly and daily values and value for the reference period April - October 2019. Soil respiration values obtained by different methods were almost identical (0,8 g CO2 m-2 h-1). We derived the exponential dependence of soil respiration from automatic measurements from soil temperature, whitch will be used in modeling of soil respiration in similar habitat conditions.Respiration values determined by Eddy covariance method we used to verify the accuracy of manual and automatic measurements. Synchronous operation of soil respiration values in all measurements confirms that the measurements are reliable. Values of soil respiration in 2019 were almost identical to the values from 2013 and this fact testifies to the stabilization of ecological conditions after the interruption of the wind disaster in 2004. Also measurements of C flows from the calamity area determined from the eddy covariance tower in 2019 and 2018, confirmed that C emissions are stabilized, which contributes to the current positive C balance of the calamity area.
