Soil Salinity Assessment Using The Em38: Field Operating Instructions And Data Interpretation, D L. Bennett, Richard George, Arjen Ryder
Agriculture reports
The Geonics EM38® is a portable instrument designed to take in situ field measurements of soil conductivity to about 1.5 m depth. If used correctly, the EM38 allows rapid, reliable estimates of soil salinity to be obtained from large areas without intensive soil sampling. The meter is very useful for delineating the extent and relative severity of saline areas. Although soil salinity has the dominant effect on the EM38 signal, other soil physical factors such as clay content, moisture content and temperature can affect the response. If the EM38 measurements are to be related to plant performance and used for …
Rangeland Reference Areas : Summary Of Cooperative Project Between The Western Australian Department Of Agriculture And The Environmental Protection Authority, D A. Blood
Resource management technical reports
The development of agriculture in south-western Australia has been characterised by the replacement of deep-rooted, perennial species of native vegetation with shallow-rooted, annual species. Except for the high rainfall areas, the native vegetation was able to intercept and transpire nearly all of the rainfall resulting in low stream flows and recharge to a groundwater system which was typically deep and restricted to the major valleys. The lack of surface or groundwater movement out of inland catchments used large quantities of cyclic salts to become stored in the regolith. Although annual crops and pastures can be high water users, they are …

Land Resources Of The Bencubbin Area, Gerard J. Grealish, John Wagnon
Land resources series
This survey of the Bencubbin area is part of the Agriculture Western Australia's regional land resource mapping program, and covers approximately 1.5 million hectares in the Merredin, Trayning, Koorda, Mount Marshall, Mukinbudin, Westonia and Nungarin Shires of Western Australia. The climate is Mediterranean, with hot dry summers and cool winters. Land is used for winter cereal production and grazing, and about 60% is cropped each year. Wheat is the main crop and is grown in rotation with lupins, field peas, barley and medic pasture. This report provides primary and interpreted information on the character and capability of the land, for …

Managing the rangelands is complex. Soils and vegetation can vary considerably over short distances in distinct or subtle ways. Separating climatic from management influences on the condition of the land has always been difficult. Whether we live on a sheep station, in a country town, in an Aboriginal community, a mining camp, or even if we only visit the Australian outback, it is vital that we understand and appreciate the unique character and management requirements of the rangelands. Learning to ‘read the rangeland’ has been a slow process, involving the knowledge and skills of pastoralists, Aboriginal people and scientists. This …
Soil Information Sheets For Ravensthorpe And Part Of The Jerramungup Agricultural Areas, Tim D. Overheu, Landcare Western Australia.
Soil Information Sheets For Ravensthorpe And Part Of The Jerramungup Agricultural Areas, Tim D. Overheu, Landcare Western Australia.
Agriculture reports
The soil information sheets produced for the Ravensthorpe Land Conservation District provide an easy reference guide to the soils for part of the Jerramungup and Ravensthorpe agricultural areas, and provide land use and soil management recommendations. Soil data are shown on the front of the sheet, and land use and land management information is given on the back. The information should be used as a guide, and encourage the user to seek further information through the relevant people and organisations.
