Plant roots and soil microorganisms emit nine times more carbon dioxide (CO2) than anthropogenic emissions annually. Therefore, accurate and frequent measurements of CO2 emissions from soil are essential for characterizing carbon emissions and understanding carbon sequestration in soil. CO2 concentrations can be continuously measured with automated chambers connected to an infrared gas analyser (IRGA) or laser spectroscopy instruments. However, these instruments are expensive, labour-intensive and cumbersome to transport.
