Abstract

This report presents soil and landform mapping of about one million hectares in the Avon Valley and central wheatbelt of Western Australia at scale of 1:100,000. The study area spans from the lateritic plateau of the Darling Range to the broad, flat landscape of the wheatbelt and covers four broad physiographic regions: • the Zone of Ancient Drainage; • the Zone of Rejuvenated Drainage; • the West Kokeby Zone; and • the Darling Range Zone. Twenty-five soil landscape units were identified and mapped on the accompanying map sheets. A soil landscape unit is an area of land that occurs in a recognisable position in the landscape and contains a specific set of soil types. The landform, location, parent material, native vegetation and soil types of each soil landscape unit are described within the text. Forty-two soil types were identified and described and a brief comment made on their capability for agriculture. Section 4.1 rates the capability of these soil types to support common agricultural land uses and lists their limitations. The area of each soil landscape unit and each soil type were calculated. An estimate of the percentage occurrence of individual soil types within each soil landscape unit is given. The major use of this study will be regional land use planning. The soil landform maps have been interpreted to produce land degradation hazard maps and land capability maps for common land uses.
