In this study,
soil CO2 effluxes determined from CO2 concentration
gradients were compared to effluxes obtained with automated chamber
measurements. The CO2 concentrations showed a diurnal pattern following
the soil temperature the concentrations increasing with increasing soil depth.
Both methods gave comparable CO2 effluxes indicating that the
gradient method provides an alternative method for monitoring soil CO2
effluxes.
