When normally dry soils were submerged in water, the pH increased and Eh decreased in both soil and supernatant liquid, equilibrium values being attained in 80 days. This also occurred if the soil was treated with acid or compost was added, although the initial and final values were different. The iron content of the supernatant liquid was very low, but that in the ‘drained soil solution’ increased with fall of pH and Eh.
