Although their occurrence is sporadic, the world's total area of pyritic soils is enormous. Such soils can be virtually worthless due to an accumulation of acid sulphate resulting from the oxidation of pyrite, but techniques have been developed—based particularly on careful control of the water table—to bring them into productive cultivation. This article reviews the causes of acidity and control methods used in various parts of the world.
