The objective of this work was to present and discuss some aspects of the soil CO2 efflux. We definedherein, some terms associated to the soil respiration concept, we tackled some aspects regarding the influence oftemperature, humidity and soil pH on soil respiration and we presented the principle of soil respiration measurement byusing dynamic closed chamber system. %K respiration %K carbon cycle %K dynamic closed chamber system %U http://proenvironment.ro/promediu/article/viewFile/4838/4492
