Miscellaneous Publication 42/93 - Development And Dissemination Of Design Methods For Rangeland Paddocks Which Maximise Animal Production And Minimise Land Degradation, Shane Cridland, Mark Stafford Smith
Animal production and livestock published reports
Surveys of rangeland resources in Western Australia to date have shown that 23% of the area surveyed is in poor range condition. Poor condition is characterised by the loss of perennial vegetation allowing wind and water erosion. Approximately another 37% is in only fair range condition (Curry and Hacker 1990).
The loss of range condition is partly due to uneven use of paddocks by sheep and cattle. The areas close to water and the preferred pasture types are often over-utilised, while areas well away from water and less preferred pasture types are under-utilised. The result is that rangeland in good, …

Bulletin 4267 - Growing Macadamia Nuts, John Dick, Alec Mccarthy
Bulletins 4000 -
The macadamia (Macadamia integrifolia and M. tetraphylla) are native Australian trees that have been developed as a commercial food crop.
About two million macadamia trees are planted in Australia over 6000 hectares. These produce about 12,000 tonnes of nuts. New South Wales and Queensland account for 90 per cent of the trees.
Unfortunately, Western Australian conditions are different again to the eastern States. Therefore, local trials will be required before varieties particularly suited to this State's conditions can be developed.
Bulletin 4247 - Introduction To Commercial Mushroom Growing, Margaret Graham
Bulletin 4247 - Introduction To Commercial Mushroom Growing, Margaret Graham
Bulletins 4000 -
Mushroom cultivation began in Australia in the 1930s in the then incomplete and unused Circular Quay railway tunnel in Sydney. In the 1950s most mushrooms were grown in heaped or 'ridge-beds' of compost in disused railway tunnels.
In the last 15 to 20 years there has been considerable technical change in the method and degree of sophistication of mushroom cultivation techniques. Most growers have invested large sums of capital in specially designed and insulated buildings that control temperature, humidity and ventilation and where pest and disease prevention and control is less difficult.
The bag method also helps to alleviate pest …

Bulletin 4274 - Tree Planting On The High Rainfall Coastal Plain, Don Bennett, Richard George
Bulletins 4000 -
Careful planning can mean the difference between the success or failure of a tree planting program . Healthy , well-e stablished trees stand a better chance of survival, grow faster and are more resistant to insect attack. The need for time-consuming watering in summer is also eliminated.
The high rainfall coastal plain extends from Perth to Busselton and inland to the Darling Scarp. It receives about 800 to 1000 mm annual rainfall.
Site preparation is ideally started in summer. For a winter planting, decide before March where to plant, which varieties and how many trees to plant. Early planning allows …

Jerramungup "Moort Type" Soils - Soil Description, Analyses And Discussion, Tim Overheu Mr
All other publications
Hard Setting Grey Clays, colloquially termed Moort Clays by the Central South Coast farmers of Western Australia, fall into the typical class of Sunday soils (i.e. too dry to sow a crop on Saturday and too wet on Monday) - acknowledgment that these soils can be difficult to manage. The local soil name derives from the dominant endemic vegetation growing on this soil (Eucalyptus platypus ssp) usually with no competing understory vegetation. Moort clays are most often found on mid to upper valley slopes and depending on parent material and pedogenesis are often alkaline (sometimes acidic), hard setting, sometimes cracking, …

Bulletin 4256 - Pecan Nut Cultivation, Aldo Labrosciano
Bulletins 4000 -
Pecans Carya illinoensis, an indigenous species to Northern America, are successfully grown between the latitudes of 25° and 35°. There is considerable variation in size and flavour of the 1000 or more varieties of the nuts.
Large scale production is concentrated in north America, Israel and South Africa. Plantings in Australia are in Victoria and New South Wales, and are developing slowly in Western Australia.
Pecans are well suited to Western Australian conditions where the soil is well drained. Though the trees are deciduous, they have no chill requirement and will flourish if water is not limiting.

Visions For Agriculture, Department Of Agriculture, Western Australia
Agriculture reports
This workshop grew out of a conversation between Maurice Barnes, a Trayning farmer and member of the Research Advisory Committee of the Dryland Research Institute, and Steve Porritt, the officer in charge of the Dryland Research Institute at Merredin. Maurice was interested in the idea of posing the question 'What would agriculture be like if we had known as much about this landscape in 1829 as we know now?', to a group of farmers and others interested in the central wheatbelt and its future. Maurice saw this question as a first step toward achieving some shared vision for the future …

Worm Control In Sheep In Western Australia. Crack Down On Worms: An Information Guide For Advisers, Consultants, Livestock Personnel And Farmers, Department Of Agriculture, Western Australia
Animal production and livestock published reports
In Western Australia’s winter rainfall areas, the control of gastro-intestinal sheep worms is based on the strategic timing of drenches.
Sheep are drenched at a time that reduces the contamination of pastures with worm eggs and larvae in late summer and autumn. The timing of the drenches is particularly important for the control ofbrown stomach worms (Ostertagia species) and black scour worms (Trichostrongylus species)
Drenches given in late spring, when pasture is starting to dry off, and again in summer, successfully reduce pasture contamination in mid summer and autumn. A faecal egg count will determine the need and timing of …

Post-Shearing Losses Of Sheep Following Cyclonic Rains, M. Holm Glass, R. Jacob
Animal production and livestock published reports
Sudden unpredicted rainfall during summer has caused high mortality rates in newly shorn sheep on at least two previous occasions. These occurred at Darkan, Western Australia, in 1982 (Buckman 1982) and at Kybylolite in the south-east of South Australia in 1960 (Geytenbeek 1982).
Geytenbeek (1982) reported an average mortality of 8.3%, which was highest for sheep within five days of shearing. The mortality declined for animals shorn more than seven days before the rain.
Buckman (1982) reported an average mortality of 27.9% which was highest within 12 days of shearing. The losses related directly to the amount of rain received. …

Miscellaneous Publication 39/91 - How To Eradicate Virulent Footrot From Your Property. A Farmer's Guide., Dianne Hopkins
Animal production and livestock published reports
The first thing to understand about virulent footrot is that it can occur on any farm in the medium to high rainfall zone.
People often associate footrot with properties managed by inefficient farmers. This is a belief based on fallacy. Many good farmers have found the disease in their sheep, including high profile stud producers.
Footrot can strike anywhere and without warning.
The important thing to remember is, that once it is found, getting to know the disease and understanding it will help you beat it. This manual, the video and your stock inspector will help you eradicate footrot from …

Miscellaneous Publication 17/91 - Mudas - Model Of An Uncertain Dryland Agricultural System: A Description, R. S. Kingwell, A. D. Bathgate
Farm Systems and Economics research reports
In the early 1980s, the Department of Agriculture developed a mixed integer whole-farm mathematical programming model of the dryland farming system in the eastern wheatbelt of Western Australia (Morrison et al. 1986). The model named MIDAS (Model of an Integrated Dryland Agricultural System) was constructed, tested and scrutinised by a multi-disciplinary team of researchers, advisers, farm management consultants and farmers (Kingwell 1987a). The model described in some detail the biology and finances of the dryland farming system in an average season and calculated profit-maximising farm plans.
MIDAS remains an often used tool in research and extension, being applied to many …

Farm Systems and Economics published reports
Historically, commodity prices cycle between a "boom and a bust" every few years. Farmers are often able to adjust their operations to reduce the impact of a downturn in commodity prices by:
-
Increasing efficiency through reducing or maintaining input costs while maintaining or increasing production levels.
-
Maximising returns through seeking price premiums on commodities (protein, noodle quality, finer wool, increased clean wool yield).
-
Reducing overhead costs
-
Seeking cheaper finance or refinancing costly loans
-
Careful planning and management with a high degree of attention to detail.
-
Seeking advice
