Soil respiration was measured by closed chamber and gradient methods in soils under
forest, sown meadow and crops. Annual total soil respiration determined with the closed …

Soil respiration forms a substantial part of the ecosystem respiration. However, the
respiration measurements conducted with chambers on the soil surface do not give …

Measurement of overall respiratory activity of litter and soil or" total soil respiration" has
interested ecologists for several decades (Domsch 1962, Haber 1958, Lundegardh 1924 …

Agricultural systems are sources and sinks for carbon and to quantify the net effect of these
systems on atmospheric CO2 concentration, the amounts of carbon fixed in primary …

A study was made of the effect of soil and crop type on the soil and total ecosystem
respiration rates in agricultural soils in southern Finland. The main interest was to compare …

The absolute values of the CO2 output from the soil and litter system obtained on an
Alopecurus-dominant site mostly varied between 9.5-23.8 g CO2m-2. day-1 in two …

An acceleration of soil respiration with decreasing CO 2 concentration was suggested in the
field measurements. The result supporrs that obtained in laboratory experiments in our …

Within terrestrial ecosystems, the soil CO2 efflux is one of the largest carbon flux
components. The global efflux of carbon from the soil is estimated between 50 and 75 Gt C …

The carbon dioxide efflux to the atmosphere and the concentrations at various depths in two
soils were measured, for more than a year, under pure stands of silver fir (Abies alba Mill.) …

Soil respiration during the growing season was calculated from CO2 profiles in a heavy clay
soil under native grass and on cultivated plots. Soil respiration of the native grass plots was …
