Land resources in the northern section of the Peel-Harvey catchment, Swan Coastal Plain, Western Australia Map

Land Resources Map and Land Capability table for the northern section of the Peel-Harvey catchment. Prepared to assist nutrient management and land use planning in the southern section of the Peel-Harvey catchment

Digital Information in the Peel-Harvey Catchment Area

This paper presents a summary of the main features of the digital mapping data available in the Peel-Harvey Catchment area. This type of information is essential for Geographic Information System (GIS) users to assess projects involving the use of digital data such as plotting of mapped themes, topological overlays, area calculations and reporting

Identifying soil constraints that limit wheat yield in the south-west of Western Australia

This is a novel approach using regional-scale information. The analysis estimated that: most of the wheat-growing land in south-west WA has one or more soil constraints about 1.6 million hectares (9% of the total area) are not suitable for cropping about 2.2 million hectares (12% of the total area) are suitable for cropping but are subject to many (more than 3) constraints; soil amelioration is unlikely to significantly improve profitable yield gain subsurface acidity extends over 12.6 million hectares (about 70% of the total area); about 7.6 million hectares of that area (42% of the total area) is estimated to have only 1 or 2 soil constraints, and treating the most-limiting constraint is likely to achieve a profitable yield gain subsurface compaction susceptibility extends over 13.2 million hectares (about 73% of the total area); about 5.7 million hectares of that area (about 32% of the total area) is estimated to have only 1 or 2 soil constraints, and treating the most-limiting constraint is likely to achieve a a profitable yield gain water repellence, surface salinity, subsoil alkalinity, low soil water storage, topsoil acidity and physical crop-rooting depth each restrict yield over at least 1 million hectares

Wheat yield potential and land management constraints in the South West of Western Australia

This report provides the underpinning information to help improve the long term profitability of wheat cropping. It documents the realistic potential yield of the 18 million hectares of agricultural land in the South West of Western Australia and the gap between this potential and the actual yields, based on shire averages. This report also summarises major land management constraints that limit the yield potential. This information can be used to aid strategic planning at different levels, for example state, shire and, with care, as a starting point for farm planning

Data dictionary, Coastal land and groundwater for horticulture from Gingin to Augusta

This report summaries the primary digital data which was used to analyse the land and groundwater resources along the coastal strip between the shires of Gingin adn Augusta - Margaret River

Identification and classification of “new” semi-arid soils from the Pilbara WA with potential additions to the Australian Soil Classification

As part of the Department of Primary Industries and Regional Development’s (DPIRD) Transforming Agriculture in the Pilbara (TAP) project, a land assessment of the region was conducted to identify areas with potential for irrigated agriculture. The morphology of the dominant soils is described together with their chemical and physical properties
