Desctription:

Soil respiration measurement is the main way for carbon to return to the atmosphere from
terrestrial ecosystem, and it is also the characterization of life activities in soil. Accurate
measurement of its release is the key to evaluate the biological process in ecosystem; By monitoring
soil respiration and its related parameters, the response of root box soil microorganisms to climate
change can be estimated. Soil CO2 flux is affected by many complex physical and biological
processes in time and space. Long-term, continuous and accurate measurement of soil carbon flux
is of great significance to the study of terrestrial ecosystem carbon flux. The soil respiration meter
can simultaneously display the CO2 concentration, soil temperature, photosynthetic effective
radiation intensity, flow, air temperature and humidity of the respiration chamber.
