This land resource survey of the Corrigin area covers some 1.8 million hectares of the central wheatbelt over the shires of Beverley, Brookton, Bruce Rock, Corrigin, Cuballing, Cunderdin, Dumbleyung, Kellerberrin, Kondinin, Kulin, Lake Grace, Merredin, Narembeen, Narrogin, Pingelly, Quairading, Tammin, Wandering and Wickepin. The survey is part of a regional scale soil-landscape mapping program designed to deliver seamless soil information for the agricultural area of south western Australia. The information provided will assist planners, researchers and land managers make decisions affecting sustainable land use and is designed for use at regional and catchment scales. This report and accompanying CD-ROM summarizes primary and interpreted information on the soil-landscapes of the Corrigin area. The report outlines the main degradation issues and supplies background information on climate, native vegetation and geology. An important additional outcome of the survey is a new theory on soil formation that has wide-ranging ramifications for agriculture, soil science, botany and geomorphology. Thirty-six soil-landscape systems, together with their component sub-systems and phases were recognised, mapped and described during the survey. This information, together with unmapped soil types and land qualities, is provided in the CD-ROM. The CD also showcases the main soils, provides geo-referenced soil pit and auger descriptions, maps of soil-landscapes and maps of selected degradation hazards
