    The Soil Respiration System consists of the SRC-1 Soil Respiration Chamber and either the EGM Environmental Gas Monitor or CIRAS Differential CO2/H2O Infrared Gas Analyzers.The method of measuring soil respiration is that described by Dr. K.J. Parkinson in 1981, where a chamber of known volume is placed on the soil and the rate of increase in CO2 within the chamber is monitored. In the original method, air samples were withdrawn at one minute intervals and separately analysed. With this system, the air is continuously sampled in a closed circuit through the EGM or CIRAS, and the soil respiration rate is calculated, displayed and recorded by the analyser. The air within the chamber is carefully mixed to ensure representative sampling without generating pressure differences which would affect the evolution of CO2 from the soil surface.
