ABSTRACT
Australia has a developed and extensive agricultural sector; grazing is especially important. Processes of land degradation and desertification are widespread in Australia, and soil science provides a necessary scientific basis for land conservation, improvement and reclamation. It is quite natural that soil classifications were developed in this country as early as the beginning of the 20th century. The objectives of the Australian classification were to serve as a basis for soil inventory and mapping. The recent version of soil classification of Australia (Isbell, 2002) has the same aim and has national coverage (Table 27.1). The scope of the Australian soil classification
