Changing Land Use On Unproductive Soils, Andrew Blake, Mike Clarke, Angela Stuart-Street

Resource management technical reports

A three year study completed in 2010 examined farming systems in the north-eastern agricultural region and eastern wheatbelt of Western Australia which experienced a succession of variable seasons from 2000. This culminated in severe drought in 2006 and 2007. At that time, farmers experienced labour shortages and declining terms of trade triggered by cost inflation outpacing growth in commodity prices. As a result, farm business equity was eroded as farm debt escalated. This left many farm businesses in a highly vulnerable state. At the time of the study many farmers were facing an uncertain future.

These experiences, coupled with a …

Soil Survey Of The Bettink Dairy Farm, Riverway Road, Northcliffe, Peter J. Tille, Tilwin Westrup

Resource management technical reports

This soil survey of the Bettink dairy farm in Northcliffe, Western Australia aimed to: provide detailed soil descriptions to add to information associated with the environment in which the dairy industry in Western Australia is located; collect soil samples at predetermined standard depths from documented farm locations for nutrient analysis; map soils with similar characteristics based on description and analysis.

Farm Water For The North-Eastern And Eastern Wheatbelt Of Western Australia (Zones 2 And 5), Susan Murphy-White

Resource management technical reports

Large proportions of Western Australia's dryland farms suffer from water supply problems in the form of shortages, poor quality or combinations of these two factors ... A regional study for the North-eastern and Eastern Wheatbelt of Western Australia was undertaken. The base data used to develop water supply areas included soil type, landscape units, geology, hydrogeology, native vegetation and existing far water resource infrastructure.

Agricultural Sub-Regions Of The Avon River Basin, Paul D. Galloway

Resource management technical reports

This report identifies, describes and locates nine sub-regions within the land cleared for agricultural uses in the Avon River Basin in Western Australia. The sub-regions are: Darling Range; Dale/Upper Avon; Avon Valley; Yealering Lakes; Mortlock; Northern Sandplain; south-east Lakes; Carrabin; Southern Cross. The sub-regions are described in terms of their distinguishing biophysical characteristics of: soils and related original vegetative cover; general topography; surface and sub-surface hyrdological stus; underlying geology; and rainfall and evapotranspiration range. Current dominant land use, economic drivers and land use pressures are identified for each sub-region.

High Water Use Plant Options For The Fitzgerald River Catchment : A Case Study, P L. Hill, Nadene Schiller

Resource management technical reports

This report summarises the outcomes of a project initiated to examine the potential to integrate high water use plant options into existing farm systems to combat rising watertables and reduce salinity and waterlogging. Planting options investigated include commercial trees, perennials, fodder shrubs, annual crops and native grasses. The research uses a new GIS based methodology for undertaking catchment scale land capability analyses.

Land Capability Assessment For The Wellington-Blackwood Survey, Peter J. Tille

Resource management technical reports

This report has been produced to provide more detail on the land capability assessments presented in the Wellington-Blackwood Land Resources Survey (Tille 1996). In that report, the land capability of each of the soil-landscape subsystems has been summarised with a brief description. Capability ratings are provided here for each of the map units (including subsystem phases) which appear on the two map sheets (Tille et al. 1996) accompanying the Wellington-Blackwood Land Resources Survey.
