A simple rubber membrane gas sampling device is described for measuring soil oxygen and carbon dioxide levels. The O 2 measurements are compared to results from the Pt electrode method and found to show similar trends when soil respiration was low. The membrane sensor samples a larger volume of soil and so its results have lesser coefficients of variation than do oxygen diffusion rate (ODR) measurements with Pt electrodes.
