Emissions of CO2 from some soils

Emissions of carbon dioxide were measured from diverse soils in the surroundings of Málaga (Spain). These measurements were carried out by two methods. A direct method using a static open chamber technique and another indirect method obtained from simultaneously measured 222Rn flux and concentration profile measurements of 222Rn and CO2 in the air of soil. The directly measured CO2 fluxes at investigated sites is slightly higher than CO2 fluxes derived from the indirect method. Carbon dioxide emitted by soils, showed a mean direct flux to the atmosphere of 5 mmol M−2 h−1.
