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.

Tree Windbreaks In The Wheatbelt, Robert Sudmeyer, David Bicknell, Neil Coles

Bulletins 4000 -

Windbreaks comprising trees, or tree and shrub combinations, can offer many benefits on wheatbelt farms, particularly for protection of soil, stock, crops and pastures from damaging winds and erosion. Additional benefits include reduced evaporation from farm dams, reduced groundwater recharge, their use as nature conservation corridors and habitats, increased biodiversity including predators of crop and pasture pests, fire control, tree products and improved lifestyle and aesthetics.

In other areas and farming systems such as intensive horticulture, man-made windbreaks may be used, but their higher cost makes them unsuited for broadscale agriculture. Man-made windbreaks can be effective in reducing evaporative losses …

Outcomes Of The Wetline Review. The Minister For Fisheries’ Decisions In Relation To The Future Management Of The West Coast And Gascoyne Commercial “Wetline” Fisheries, Department Of Fisheries Western Australia.

Fisheries management papers

This document details my final decisions on the new management arrangements for the West Coast and Gascoyne commercial ‘wetline’ fisheries. The decisions that are set out in this document will form an important part of the holistic management package required to ensure the long-term sustainability of our demersal scalefish resources in the West Coast and Gascoyne bioregions. The new Management Plans will provide the framework within which commercial scalefish catches can be explicitly managed to sustainable levels and will promote greater commercial certainty and confidence for those operators who gain access to the fishery.

Sedimentology Of Acid Saline Lakes In Southern Western Australia: Newly Described Processes And Products Of An Extreme Environment, Kathleen Counter Benison, Brenda Beitler Bowen, Francisca Oboh-Ikuenobe, Elliot A. Jagniecki, Deidre A. Laclair, Stacy L. Story, Melanie R. Mormile, Boyoung Hong

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

Naturally acid saline systems with pH values between 1.7 and 4 are common on the Yilgarn Craton of southern Western Australia. a combination of physical and chemical processes here yield a previously undescribed type of modern sedimentary environment. Flooding, evapoconcentration, desiccation, and eolian transport at the surface, as well as influx of acid saline groundwaters, strongly influence these lakes. Halite, gypsum, kaolinite, and iron oxides precipitate from acid hypersaline lake waters. Shallow acid saline groundwaters affect the sediments of the lakes and associated mudflats, sandflats, channels, and dunes by precipitating early diagenetic halite, gypsum, iron oxides, clays, jarosite, and alunite. …

The aim of this Resource Management Technical Report is to assess the current extent of salinity and other natural resource degradation issues in the Boyup Brook - Upper Warren area and provide landholders with the best current management options to address natural resource management issues and enhance sustainable agricultural production.

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.

West Midlands Region Catchment Appraisal 2007, Angela Stuart-Street, Northern Agricultural Region Catchment Appraisal Team

Resource management technical reports

Annual run-off likely to occur was calculated for farm-scale catchments within the 500-825 millimetre rainfall zone of the South West Catchment Council [Western Australia] area. When compared with historical flow measurements, this method was found to be accurate (or conservative) in 85% of all measured years, indicating its usefulness for predicting reliable annual flows.
