Introduction
Soil acidification is a major concern in Australia (Donald and Williams 1954; Williams 1980; Coventry and Slattery 1991), especially in the wheatbelt area of eastern Australia (Greenland 1971; Cregan et al. 1979; Helyar et al. 1990). Acidification may not be confined to the surface soil but may extend to depths of 30 cm (Williams 1980) to 60 cm (Bromfield et al. 1983) into the subsoil in eastern Australia and to 80 cm in Western Australia (Dolling and Porter 1994). In some studies the investigation of profile acidification has been determined for soil samples taken in depth intervals of 5 or 10 cm (e.g. Williams 1980; Bromfield et al. 1983; ...
