Carbon dioxide is one of the greenhouse gases responsible for the effects of climate change. The soil respiration process is an important component of the carbon circuit in nature, through which carbon dioxide returns to the atmosphere. The concentration of CO 2 in the atmosphere is directly influenced by any change of carbon flow produced in soil, as the latter is the largest carbon sink in terrestrial ecosystems. The objective of this paper is to present the experimental results obtained using CO 2 flow determination with portable GHG analyzer with closed static chamber, and the relation and influence of the main pedoclimatic parameters, namely temperature and humidity. Future research directions will consider the development of a plan to monitor CO 2 flow from the soil, for different types of land use, in different climatic conditions. During one month of data collection, has been found that soil CO 2 efflux was influenced by soil moisture and soil temperature. Also, the processed data showed how soil respiration rates were dependent on soil moisture.
