Comparing the closed static versus the closed dynamic chamber flux methodology: implications for soil respiration studies

The study found that the closed static chamber (CSC) approach typically underestimates soil CO2 fluxes compared to the closed dynamic chamber (CDC) system when using long sampling periods, but provides comparable results when sampling is limited to the initial 15 minutes.

• The closed static chamber (CSC) approach tends to underestimate CO2 fluxes due to the asymptotic increase of CO2 concentrations in the headspace during long manual sampling periods.
• When calculated over a 75-minute period, the CSC approach underestimated fluxes by 30% for combined samples, 21% for mineral soils, and 39% for peat soils compared to the CDC system.
• CSC measurements are comparable to the CDC system if sampling is conducted at an appropriate initial frequency, specifically over the first 15 minutes.
