CO2 soil respiration

The CO₂ respiration from soil is a good indicator of overall biological activity of the soil, and is often used when studying the carbon cycle. The CO₂ flux can be measured on the soil surface in respiration chambers. Belowground CO₂ profile measurements can be made at variable depths in the soil.
