Large decreases in redox potentials of saturated soil over a 25‐day incubation period were favored by high temperature and the addition of sucrose, loblolly pine needles ( Pinus taeda L.), or yellow‐poplar leaves ( Liriodendron tulipifera L.). The addition of a complete nutrient solution had no effect in soils incubated with sucrose, but it reduced the drop in potential in soils incubated with tree litter at 21–27C. The data suggest the need for care when evaluating soil aeration by means of redox potentials and the dominant role of soil microorganisms in activating redox systems.
