Surface Soil Acidity (ASRIS)

Soils are classified according to the pH of the surface layer, according to the lower pH values recorded among similar soils, i.e. it is assumed that each soil class has a characteristic level of acidity, or is prone to that level of acidity under current climate and typical agricultural land use expected for that soil and locality. Surface soils are classified according to degree of acidity, and surface buffering capacity. This analysis is based on Soil Landscape Mapping of SA's agricultural districts using soil class information in the nationally-consistent Australian Soil Resource Information System (ASRIS) data format.
