Cost Effective Stubble Retention Practices, Andrew Green, Ed Blanchard

Journal of the Department of Agriculture, Western Australia, Series 4

To increase the rate of adoption of stubble retention farming systems the Grains Research and Development Corporation is funding a three-year project with the Farm Machinery Unit to develop low cost, stubble handling systems from harvest to seeding

Tree Crops For Profit And Land Improvement, John Bartle

Journal of the Department of Agriculture, Western Australia, Series 4

Western Australian agriculture is deficient in good perennial species. The traditional segregation of agriculture and forestry has diverted attention from commercial wood producing trees as a potential perennial crop. Recently, scientists have made rapid progress in developing tree cropping systems suitable for extensive use in the wetter (more than 600 mm average annual rainfall) areas of the lower south-west. There is potential for a major industry based on fast-growing eucalypts for pulpwood. The foundations for this industry developed from work on agroforestry, forestry sharefarming and salinity control.

Drought Proofing The Farm : Case Studies, J L. Frith

Journal of the Department of Agriculture, Western Australia, Series 4

For many years, Western Australia's north-eastern wheatbelthas suffered chronic shortages of water for stock and domestic use. The area's averageannual rainfall is generally low - less than 300 millimetres - and droughts in the 1970s caused futher problems. manydams in the area leak or have inadequate catchmentsand groundwater is scarce ormofmpoor quality.

In March 982, the Western Australian Government provided $100 000 for the Department of agriculture to demonstrate the potential of establishing permanent, drought-proof water supplies on farms in the north-eastern wheatbelt. The methods were to use exixting techniques to build dams and catchments. In a year of low …

Contour Cultivation : Cheap Erosion Control, T R. Negus, B. Barrett

Journal of the Department of Agriculture, Western Australia, Series 4

Although the benefits of contour cultivation are well recognised, it makes cultivation more difficult, particularly if the paddock is split by contour banks and grassed waterways. However, a comparison east of Pingelly indicates that contour cultivation is little more expensive or time-consuming than ordinary cultivation.

Cost Of Farm Water Supplies : Conclusions From Surveys, I A F Laing

Journal of the Department of Agriculture, Western Australia, Series 4

The Department of Agriculture, in conjunction with the Farm Water Supply Advisory Committee, has conducted farm wster supply surveys in many districts in the wheatbelt.

The aim of the surveys was to collect data to assess the existing water supplies, the potential for further water supply developments and to compare the relative difficulty of water supply development in different localities.

Entering The Egg Industry With Laying Cages, W Ward

Journal of the Department of Agriculture, Western Australia, Series 4

DEPARTMENT of Agriculture Bulletin 3579, "Entering the Egg Industry with Laying Cages", by W. Ward, examines various aspects of the cage system of housing laying hens.

This system is by far the most popular method of housing layers, with 90 per cent, of new farms using cages and many daep litter farms now converting to cages.

Private Irrigation Systems : Do They Pay?, G D. Oliver

Journal of the Department of Agriculture, Western Australia, Series 4

WESTERN AUSTRALIA, with 71,000 acres under irrigation, can hardly claim to have an important irrigation farming industry.

However, irrigation is daily growing in importance, especially through private schemes. These account for almost half the present irrigated area.
