Soil Test And Phosphorus Rate For High Rainfall Clover Pastures, Robert Summers, David Weaver Jun 2011

Soil Test And Phosphorus Rate For High Rainfall Clover Pastures, Robert Summers, David Weaver

Bulletins 4000 -

When new land was first developed, phosphatic fertilisers had to be applied at high rates to overcome Phosphorus (P) deficiency, and to increase P fertility. Once good P fertility has been established after a number of years of applying P, the requirement for applying high rates of P falls. After that you only need to apply enough fertiliser P to replace that removed in products, fixed by the soil, eroded and leached, that is a maintenance rate of P.

In relation to P fertiliser decisions for pastures you need to ask:

• Do I need P?

• How do I find out ...


Potassium For High Rainfall Pastures, Mike Bolland, Bill Russell Jan 2010

Potassium For High Rainfall Pastures, Mike Bolland, Bill Russell

Bulletins 4000 -

Potassium plays a major role in plant growth. It maintains the solutions in plant cells at ionic strengths suitable for maintaining strong plant walls and for the proper functioning of leaf pores (stomata) and plant processes such as photosynthesis, transport of sugars and enzyme activation.

Potassium does not become a direct part of the plant structure but acts to regulate water balances, nutrient and sugar movement in plant tissue. Plants deficient in potassium cannot use other nutrients and water efficiently. They are less tolerant of stresses such as drought and waterlogging and are more susceptible to pests and diseases.


Southern Weeds And Their Control, John Moore, Judy Wheeler Jan 2008

Southern Weeds And Their Control, John Moore, Judy Wheeler

Bulletins 4000 -

This booklet provides easy identification of common weeds and methods of control using common cultural, biological and herbicidal control techniques. The weeds are divided into four colour coded groups based on their lifeform and are grasses, herbs, vines and shrubs or trees. Within each group, the weeds are listed alphabetically by their Latin name. A brief description of the herbicides used, a glossary and an index are included. Some species have been combined where they have similar control methods like the perennial grasses and Brassica weeds.

Downy Mildew In Vineyards, Diana Fisher, Andrew Taylor, Colin Gordon, Peter Magarey May 2007

Downy Mildew In Vineyards, Diana Fisher, Andrew Taylor, Colin Gordon, Peter Magarey

Bulletins 4000 -

Downy mildew, caused by Plasmopara viticola, is a major fungal disease of grapevines that originates from North America. This disease was first detected in a commercial Western Australian vineyard in October 1998 and has since been found in most grape growing areas within the State. It is found in all other grape growing areas of Australia.

Plasmopara viticola is specific to grapevines (e.g. Vitis vinifera), although not all Vitis spp. are susceptible. The American rootstock species and hybrids are less susceptible or are resistant (refer to ‘Varietal susceptibility’). Other species of downy mildew, such as those found on cucurbits ...

Uses For Canola Meal, John Bonnardeaux Jan 2007

Uses For Canola Meal, John Bonnardeaux

All other publications

Rapeseed (Brassica napus) is a bright yellow flowering member of the family Brassicaceae (mustard or cabbage family). Industrial rapeseed is high in erucic acid or H.E.A.R, with greater than 45 per cent erucic acid, which is mildly toxic to animals especially poultry. Erucic acid at levels beyond 0.605 per cent in diet is known to cause growth depression, reduction in feed intake and efficiency in growing chicks. Natural rapeseed meal also contains glucosinolates (the 'hot' in mustard seeds, when this compound is broken down with water it reacts and provides the heat felt on the tongue ...


Baby Boabs : The Exciting New Taste Sensation From The Kimberley In Western Australia, Department Of Agriculture And Food, Western Australia Mar 2006

Baby Boabs : The Exciting New Taste Sensation From The Kimberley In Western Australia, Department Of Agriculture And Food, Western Australia

Bulletins 4000 -

Baby boabs are the seedling stage of the large boab trees found in the Kimberley region. The seed of the fruit found in pods attached to the tree is planted and then grown for approximately 16 weeks depending on the season. This produces a tuber up to 30 centimetres long, with fresh, succulent, edible leaves on top.

The boab tubers are very versatile and can be used in most dishes both raw and cooked. The texture of the tubers are crisp and crunchy like that of a water chestnut but with a refreshing taste that can adapt to the other ...

Effects Of Pre-Milking Teat Sanitation On The Quality Of Raw Milk, Laurie Depiazzi, Ian Bell Jan 2002

Effects Of Pre-Milking Teat Sanitation On The Quality Of Raw Milk, Laurie Depiazzi, Ian Bell

Bulletins 4000 -

The effect of Quartermate pre-milking teat sanitation on milk quality was investigated in twelve dairy herds over a period of eight weeks. Pre-milking teat sanitation was carried out on all cows for six weeks on each of six farms and mesophile and thermophile bacteria counts of raw milks were compared before the milk line (“cluster” samples), and at various points within milking plants. Rates of mastitis, vat milk iodide levels and specific bacteria were also monitored.


Organic Vegetables : A Guide To Production, Steven Mccoy Oct 2001

Organic Vegetables : A Guide To Production, Steven Mccoy

Bulletins 4000 -

There appears to be considerable opportunity for the development of organic vegetable production in Western Australia for either fresh or processed product. While a number of growers are successfully producing relatively small quantities of organic vegetables for both domestic and export markets, few large scale commercial growers have sought to capitalise on this opportunity.

Consumer interest in organically grown vegetables has increased rapidly in recent years due largely to concerns relating to food safety, health and the environment. For more information on markets for organic vegetables refer to AGWEST publication “Market Prospects – Organic Carrots and other Vegetables”.

Western Australia Soil Acidity Research And Development Update 2000 : Time To Lime, Department Of Agriculture And Food, Western Australia

Bulletins 4000 -

We have come a long way over the past three or four years in terms of both, the level of understanding and recognition of Soil Acidity as a major land degradation issue for the wheatbelt of Western Australia, and, in our actions to treat the problem.

During 1999 there were three very significant changes relating to acid soils in Western Australia.

  • Lime use in WA increased by over 200,000 tonnes from 1998 to 1999 to a record 653,000 tonnes, which was double the amount applied in 1997.
  • The Agricultural Lime Industry adopted a voluntary Lime Industry Code of ...

Western Australia Soil Acidity Research And Development Update 1999 : Time To Lime, Department Of Agriculture And Food, Western Australia Jan 1999

Western Australia Soil Acidity Research And Development Update 1999 : Time To Lime, Department Of Agriculture And Food, Western Australia

Bulletins 4000 -

We all know we have to apply lime as part of our farming systems. This means that a huge amount of lime will be applied to soils which have never had lime applied before.

One of the effects of this is that we can now consider thinking about introducing acid-sensitive systems to soils, which previously would have been considered too acid.

The other side of liming is that the pH changes affect many soil properties. There is an element of uncertainty about whether unforeseen side effects will emerge on our fragile soils as a result of this new practice.

The ...

Western Australia Soil Acidity Research And Development Update 1998 : Time To Lime, Department Of Agriculture And Food, Western Australia

Bulletins 4000 -

Recent yield responses by canola where lime has been applied to acidic soils are very encouraging. Two sites have shown that the yield increase in canola after lime was applied in the previous year would have easily paid for the total cost of purchase, transport and application of the lime.

This work was carried out to demonstrate the increased options that are likely to be available once producers are treating or managing soil acidity. Canola is becoming increasingly important as a cash value crop and a break crop allowing wider rotations.

Growers are pushing the limits of canola’s tolerance ...

Western Australia Soil Acidity Research And Development Update 1997 : Time To Lime, Department Of Agriculture And Food, Western Australia

Bulletins 4000 -

There is a lot of lime being spread in Western Australia – or is there?

In fact, the Australian Bureau of Statistics agricultural census paints a picture showing that we are still far short of the amount of lime that should be getting on to the ground.

For many years Western Australian soils acidified without significant production penalties. The soil pH was at values that were not affecting plant growth. However, over the last decade or so, large areas of soils have reached the point where production is being affected. In addition, we are now introducing plant species such as canola ...

Beef : Meating The Market, Greg Sawyer, Richard Morris, Geoff Tudor

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

Nearly half of Western Australia's beef production is consumed on the domestic market, but the scene is changing rapidly.

In this article Greg Sawyer, Richard Morris and Geoff Tudor review information on production systems performance, and carcase and quality measurements that may well serve wider market opportunities in the future.


Something Fishy Is Going On - Aquaculture, David Berry Jan 1996

Something Fishy Is Going On - Aquaculture, David Berry

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

Aquaculture id Australia's fastest growing primary industry. Product from fish farms is currently valued at $399 million, forecast to exceed $5oo million by 2000.

Whilst the figure pales into insignificance alongside world production (about $45 billion) it does represent a huge window of opportunity for prospective investors and for Australian primary producers who are keen to diversify.

David Berry reports on the prospects for yabbie and marron farming in Western Australia.


Uht Milk : Expanding The Market, Caroline Love, Ian Bell, Martin Robertson Jan 1996

Uht Milk : Expanding The Market, Caroline Love, Ian Bell, Martin Robertson

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

An increase in the export of UHT (Ultra Heat Treated) milk to Asian markets is potentially worth millions of dollars to the dairy inmdustry. This increase however, relies on the shelf life of UHT products being extended to nine months. Spoilage of UHT milk can be caused by bacterial spores which originate on-farm and are resistant to processing. Expansion in the UHT market therefore relies on a continued reduction in the number of these spores getting into raw milk. Caroline Love, Ian Bell and Martin Robertson report on the sources of spores entering milk on-farm and the control methods available.

Canola : Golden Oil For Farmers And Consumers, Paul Carmody

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

It is feasible that canola could become Western Australia's fourth largest crop after wheat, barley and lupins by the turn of the century.

Without the stigma attached to its parent crop, rapeseed, canola has also become one of the most successful international agricultural product launches, proving itself not only a useful cropping alternative but a healthy oil for consumers. State Oilseeds Adviser PAUL CARMODY sets the scene.
