Benefits And Costs Of Saltland Pastures On Moderately Salt-Affected Land, Justin Hardy, Arjen Ryder
Benefits And Costs Of Saltland Pastures On Moderately Salt-Affected Land, Justin Hardy, Arjen Ryder
Resource management technical reports
Summary The analyses in this report show that there could be significant economic benefits to the state, regions and affected farm businesses from establishing improved saltland pasture systems on moderately salt-affected land. The report clearly describes the methods of analysis and the assumptions about prices, productivity and adoption levels. The price of grain has been used as the key factor controlling the economic value of the saltland grazing because grain is the alternative supplementary feed for sheep over the summer and autumn period. Therefore, where yield is below break-even on moderately salt-affected land, it has a higher economic value and …

Pastoral Lease Assessment Using Geospatial Analysis, T P. Robinson, P E. Novelly, R Corner, Philip Thomas, A Russell-Browm
Resource management technical reports
Seven remote sensing based Vegetation Indices (NDSVI, STVI-3, NDVI, Green + Red, Red, Land Monitor and STVI-1) were tested for their potential to discriminate between “poor” and “good” range condition assessments in Western Australia’s pastoral rangelands. Indices were computed using the Australian Greenhouse Office National Carbon Accounting System (AGO NCAS) repository of calibrated Landsat TM/ETM+ mosaics. Discrimination potential was assessed at two levels of stratification – station level (identical to the stratification used to collect the traverse data), and functional group level (an aggregation of similar land systems);
Observations Of Localised Effects Of The Busselton Compensating Basins On Surface Water, Groundwater And Soil Salinity, D L. Bennett, Richard J. George Dr
Observations Of Localised Effects Of The Busselton Compensating Basins On Surface Water, Groundwater And Soil Salinity, D L. Bennett, Richard J. George Dr
Resource management technical reports
Between 2001 and 2009 the Water Corporation constructed three flood-compensating basins on farmland in the Vasse and Sabina river catchments, upstream of in the city of Busselton. The basins are designed to reduce the risk of flooding in urban areas of Busselton by temporarily storing and then regulating runoff during flood events. This report fulfils the reporting requirements of a contract between the Water Corporation and the Department of Agriculture and Food. Data relating to the local groundwater and surface-water dynamics, salinity, nutrients and pH, plus changes to shallow and deep-soil salinity (from repeat ground-based electromagnetic induction [EM] surveying), was …
A Report On The Gascoyne River Catchment Following The 2010/11 Flood Events, P A. Waddell, P W.E Thomas, Paul A. Findlater
A Report On The Gascoyne River Catchment Following The 2010/11 Flood Events, P A. Waddell, P W.E Thomas, Paul A. Findlater
Resource management technical reports
In December 2010 an extreme tropical storm resulted in widespread flooding at Carnarvon and across the catchment. Another two flood events followed during the summer of 2010–11
The rationale for this assessment is to provide illustrative evidence on the role that perennial vegetation groundcover management has in influencing the risk of flooding and soil loss in the catchment. It may be possible that the impact of flooding associated with extreme storm events can be reduced. This report focuses on catchment condition and is not a review of the pastoral industry’s economic viability.

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

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

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