Changes in the concentration of LiCl‐extractable sulphate were measured after an atmospheric polluted brown earth soil was saturated or waterlogged (at 4°C or 25°C) with either acid rain, dilute H 2 SO 4 or deionized water. An initial marked flush of sulphate occurred in the soil following these treatments. Sulphate concentrations then decreased, however. After five weeks of saturation or waterlogging, the soils were allowed to dry out, and sulphate concentrations again increased. The results suggest that (a) sulphur may be cycled in atmospheric polluted brown earths and (b) the form and solubility of the element is influenced by soil water status.
