This report presents results from soil and landform mapping at a scale of 1:150,000 in the Katanning area of Western Australia. It is accompanied by two soil-landscape maps covering 1.45 million hectares in the Kojonup and Darkan area (map 1) and the Katanning and Dumbleyung area (map 2). Most of the Katanning survey occurs within the Blackwood River catchment but also covers the upper catchments of the Pallinup, Frankland-Gordon and Tone-Warren Rivers. The Katanning survey falls within the Narrogin and Katanning advisory districts for Agriculture Western Australia. Twenty one soil-landscape systems have been identified and are represented on the accompanying maps. Most of these systems have been further subdivided into subsystems. The main soils, landforms, geology, land use and native vegetation are described for each system. Within each subsystem, the proportion of main soil series is indicated. One hundred and forty soil series were identified in the survey. Thirty-eight are described in detail including a representative soil profile plus chemical and physical analyses from this profile if available. The main land management characteristics and native vegetation are described. Seventy-three related soil series are also described briefly. Twenty-three minor soil series and six related series that occupy small areas are described in less detail without representative profiles. The report discusses the main properties and land degradation hazards associated with the main soils identified in the survey. This is designed to give a broad overview of the capability of the soils. For specific land capability assessment it is recommended that Agriculture Western Australia’s Map Unit Database be consulted for latest assessments of land qualities and land capabilities for specific land uses. Information on land use history, geology and physiology, climate, native vegetation and previous soil surveys is included. These sections provide additional background material about the land resources within the survey area. This land resource information has been collected to help improve decisions made by planners, researchers and land managers. The information can be used from regional and catchment scales or down to farm level. By improving knowledge of our land resources, more sustainable land uses can be developed within the Katanning region.
