Summary
Pitfalls in the use of the platinum micro-electrode method of determining soil oxygen flux are described, together with an example of its use. Interpretation of current measurements as oxygen fluxes is possible only if, a) an oxygen limitation to current has been demonstrated, and then b) a suitable applied potential is used. Oxygen flux values in a well drained soil can be as low as those in a seasonally waterlogged soil. However such low flux values are usually of short duration.
