Agriculture Futures: Potential Rural Land Uses On The Palusplain, Rodney Safstrom, Nicolyn Short Dr

Resource management technical reports

The purpose of this project was to identify agricultural land use options and opportunities within the Serpentine–Jarrahdale and Murray Shires, with particular focus on the Palusplain wetland section. The report will contribute to the Department of Planning’s natural resource management plan for the region and guide development of regional and local planning strategies. Historically, the Palusplain was a slowly moving, interconnected, seasonal wetland system with areas of higher ground. Extensive clearing and drainage occurred in the late 1800s through to the mid-1900s to facilitate agriculture; however, agriculture has been found to be a major contributor of nutrients to the system. …

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 …

Groundwater Chemistry Of The Weaber Plain: Preliminary Results, Adam Lillicrap, Paul Raper, Richard J. George Dr, D L. Bennett

Resource management technical reports

In 2008, the Ord Irrigation Expansion Project was approved by the Western Australian Government to develop irrigated agriculture on the Weaber Plain. Construction of the M2 supply channel connecting the ORIA and the Weaber Plain, and the final period of irrigation design, environmental management and related approval processes, commenced later in 2009. This process followed a protracted period of public and private industry planning and environmental assessment (Kinhill 2000). This report summarises an analysis of groundwater salinity trends on the Ivanhoe and Weaber plains and the preliminary results of an intensive water-quality sampling program carried out in 2010 as part …

Surface Water Characteristics Of The Weaber Plain And Lower Keep River Catchments: Data Review And Preliminary Results, D L. Bennett, Richard J. George Dr

Resource management technical reports

In 2008, the Ord Irrigation Expansion Project was approved by the Western Australian Government to develop irrigated agriculture on the Weaber Plain.

An important concern is the effect the Weaber Plain agricultural development may have on the water quality of the downstream Border Creek and Keep River

This report assembles and reviews all available physico-chemical water quality data for the lower Keep River and Border Creek systems and presents data from the initial year of a targeted baseline monitoring program (June 2010 – June 2013).

Soil Assessment Of The Weaber Plain (Goomig) Farmlands, Henry Smolinski, Justin Laycock, Jim Dixon

Resource management technical reports

In 2008, the Ord Irrigation Expansion Project was approved by the Western Australian Government to develop irrigated agriculture on the Weaber Plain (Goomig)

As part of the environmental planning and approvals process, the WA Government was required to prepare a groundwater management plan and a hydrodynamic plan.

As a result, the Department of Agriculture and Food, Western Australia (DAFWA) was requested to lead an investigative program to support a second phase of modelling. The project was divided into five components: two addressing deficiencies related to groundwater, two relating to soils and subsoils, and one addressing surface and groundwater quality aspects. …

Designing A Soil Ph Monitoring Network For The Western Australian Wheatbelt, Karen Holmes, Pat Bellamy, Jim Dixon

Resource management technical reports

Natural resource managers in Western Australia require a purposely designed soil pH monitoring network to identify areas at higher risk of soil acidification and to observe changes in soil pH through time. This monitoring network, in conjunction with field experimental work and acidification modelling, will identify state and regional trends and help shape state natural resource management policy and regional extension programmes, as well as directly inform industry and land managers.

Weaber Plain Hydrogeology: Preliminary Results, Richard J. George Dr, John Andrew Simons, Paul Raper, Robert J. Paul, D L. Bennett, Rosemary H. Smith

Weaber Plain Aquifer Test Results, Robert Paul, Paul Raper, John Andrew Simons, Grant Stainer, Richard J. George

Resource management technical reports

As a part of the environmental planning and approvals process, the state government was required to prepare Groundwater Management and Hydrodynamic Plans. These plans are to address potential issues of salinity and water quality that could result from the development of irrigated agriculture on the Weaber Plain. The Weaber Plain groundwater modelling report (KBR 2010a) identified several options to manage watertables and salinity

Production bores 10WP35PB and 10WP36PB were drilled in the palaeochannel on sites selected from the interpretation of airborne geophysics.

Hydrological Impacts Of Integrated Oil Mallee Farming Systems, D L. Bennett, John Andrew Simons, Russell Speed

Resource management technical reports

This study reports on the results from investigations at four sites into the effect of commercial-scale oil mallee systems on localised groundwater systems over seven years. It also reports the results of the use of a numerical model to forecast potential longer term impacts.

Wheat Yield Potential And Land Management Constraints In The South West Of Western Australia, Dennis Van Gool

Resource management technical reports

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.

Mapping Acid Groundwater In Western Australia’S Wheatbelt, Karen Holmes, Adam Lillicrap

Resource management technical reports

The extent of the area affected by deep drains in Western Australia (more than 11 000 km of drains installed as of 2002: Australian Bureau of Statistics 2002) and their continuing installation by land managers make understanding the distribution of naturally occurring acid groundwater a priority for land managers working toward sustainable agricultural production in the wheatbelt. This report describes development of a map of the likelihood of acid groundwater occurrence. It is meant to guide state agencies, natural resource management groups, landholders, and community stakeholders on where acid groundwater may occur.

Esperance Area Acid Sulfate Soil Hazard Mapping, Paul Galloway, Simon Clarendon

Resource management technical reports

This project created a regional scale (1:100 000) acid sulfate soil (ASS) hazard map for the Lake Warden and Esperance town areas, using a combination of existing soil-landscape mapping information and elevation data, supported by field observations and laboratory data from 18 soil cores and 29 additional borelogs with descriptive information useful for identifying ASS and potential ASS materials. All data gathered during this project used common standards and protocols developed in Australia for identifying and mapping ASS materials. The project extends the mapping for acid sulfate soil in the region, complementing existing maps compiled for other parts of the …
