A Method for Measuring Oxygen and Carbon Dioxide in Soil1

  1. J. W. Cary and
  2. C. Holder2



A simple rubber membrane gas sampling device is described for measuring soil oxygen and carbon dioxide levels. The O2 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.
