TOKY CO2 Z KRASOVÝCH PŮD DO VNĚJŠÍ ATMOSFÉRY
Roč.19,č.1-2(2012)
CO2 fluxes from soils into external atmosphere were studied at selected sites of the Moravian Karst. CO2 escaping from soil surface was gathered in a special measuring chamber. From time evolution of the CO2 concentration in the chamber, CO2 fluxes and soil CO2 concentrations were calculated. Both the fluxes and concentrations showed strong seasonality at all sites with maximum during the spring-summer season and minimum during autumn-winter season. The maximum of CO2 fluxes and concentrations reached 6 × 10-6 mol.m-2.s-1 and 2000 ppmv, respectively. The CO2 fluxes were significantly affected by rainfall.
