SUMMARY Samples of air or water were extracted daily from porous pots buried within the rooting zone of trees planted on a deep peat soil. For most pots, the O 2 concentration in the fluid increased with the number of samples taken each day, presumably because air was drawn into the pot from shallower depths. Sampling frequency should therefore be chosen as a compromise between the needs to increase precision and to minimize introduced bias.
