Lucerne, often regarded as the queen of forages, has been used in agriculture for centuries. In Western Australia, however, its potential has never been fully realised despite its well-documented ability to dewater soils and reduce groundwater recharge. Over the years adoption has been limited by a range of factors including pests and diseases, soil acidity, grazing management and economics. During the last decade research has addressed these issues, paving the way for much greater impact at the farm and catchment level.


Managing South Coast Sandplain Soils To Yield Potential, Department Of Agriculture, Western Australia Oct 2009

Managing South Coast Sandplain Soils To Yield Potential, Department Of Agriculture, Western Australia

Bulletins 4000 -

This book has been written to help farmers reach their rainfall-limited yield potential. It comes from a need to understand the properties and management options for grain production on sandplain soils. It also seeks to address concerns that crop yields on sandplain soils are not increasing at the rate experienced on soils elsewhere in the south coast region of Western Australia.

Common Regional Pests Of Western Australia, Department Of Agriculture And Food, Western Australia

Bulletins 4000 -

Western Australia is free from many exotic animal and plant pests, diseases and weeds that are present elsewhere in Australia. However, the state does have some unwanted intruders. Of these, many are declared plants or declared animals which, for the sake of convenience, we collectively call declared pests.


Exporting Vegetables In Bulk : Reducing Supply Chain Costs Without Compromising Quality, Helen Ramsey, Dennis Phillips Jun 2009

Exporting Vegetables In Bulk : Reducing Supply Chain Costs Without Compromising Quality, Helen Ramsey, Dennis Phillips

Bulletins 4000 -

Increased competition, a strong Australian dollar and increased production costs have seen Australian grown vegetables steadily lose their share in traditional export markets.

As competition increases, we need to investigate production and handling techniques that improve our price and quality competitiveness.

Improving the effi ciency of the supply chain to export markets is one way Australian growers can reduce production and shipping costs and improve product quality.


Pasture Condition Guide For The Ord River Catchment, K Ryan, E Tierney, P Novelly Jun 2009

Pasture Condition Guide For The Ord River Catchment, K Ryan, E Tierney, P Novelly

Bulletins 4000 -

This guide has been produced as a tool for assessing pasture condition over a range of pasture types in the Ord River catchment. A pasture type is a distinctive mix of plant species, soil type and landscape position. For example, the Mitchell Grass Alluvial Plain Pasture type is a mixture of Mitchell grasses and other species occurring on black soil alluvial plains.

Pasture condition is an important factor affecting the potential of the rangelands for animal production and is a useful indicator for the sustainability of production.

Management Of Merino Weaners For Optimum Production, Patricia Harper, Keith Croker, Danny Roberts Feb 2009

Management Of Merino Weaners For Optimum Production, Patricia Harper, Keith Croker, Danny Roberts

Bulletins 4000 -

Sheep mortality during the first year of life is a large problem on many farms and poses a significant animal welfare issue for Australian agriculture. Post weaning mortality is estimated to cost the Australian sheep industry more than $89 million annually through reduced income, poor productivity and increased management expenses (Sackett et al. 2006).

A high mortality rate among weaners reduces the number of surplus animals available for sale and the number of potential breeding replacements. This, in turn, affects the selection intensity for desirable traits and the flock’s rate of genetic improvement.

Ill thrift and poor growth of weaner …


Getting Into Sheep An Introductory Guide To Sheep Management, Keith Croker, Roy Butler Feb 2009

Getting Into Sheep An Introductory Guide To Sheep Management, Keith Croker, Roy Butler

Bulletins 4000 -

Sheep husbandry can be an interesting and rewarding activity but before starting to work with or buy sheep ask yourself if you are prepared to spend the time and effort to care for them.

Sheep cannot be placed in a paddock and forgotten. The sheep, along with their water, feed and fences must be inspected regularly. If you do not live on the farm, or visit it only infrequently, make sure there is a responsible person available who is willing to inspect and manage the sheep on your behalf.


Soil Ph In Northern And Southern Areas Of The Wa Wheatbelt, Chris Gazey, Joel Andrew Jan 2009

Soil Ph In Northern And Southern Areas Of The Wa Wheatbelt, Chris Gazey, Joel Andrew

Bulletins 4000 -

More than 80% of the topsoils sampled fall below the critical surface pHCaCl2 of 5.5 in the northern and southern wheatbelt study areas, with more in the south than the north. These results confirm soil acidity is a serious concern throughout the WA wheatbelt when considered in conjunction with the more intensive analysis of current soil pH throughout the Avon River Basin (2005–2008).

With low topsoil pH, it is likely that subsurface acidity is also a problem. For soil acidity to be managed, subsurface pH also needs to be known. In the Avon River Basin study, about half of the …


Survey Of Western Australian Agricultural Lime Sources, Chris Gazey, Dave Gartner Jan 2009

Survey Of Western Australian Agricultural Lime Sources, Chris Gazey, Dave Gartner

Bulletins 4000 -

As a service to WA wheatbelt farmers, to assist with cost effective management of soil acidity, a survey of agricultural lime availability and quality was conducted by the Department of Agriculture and Food, Western Australia.

The quality of agricultural lime surveyed varied widely between pits. High quality lime is available from limes and, limestone and dolomite sources. Twice as much of the lowest neutralising value lime surveyed would need to be applied compared to the highest to achieve the same increase in soil pH. Limes also varied in the distribution of particle sizes. Selecting limes with a high proportion of …

Report On Polyacrylamide, A Practice To Reduce Sediment And Insoluable Chemicals In Tailwater, Tara Slaven

Bulletins 4000 -

The main barrier to the adoption of PAM seems to the timing of the cost of outlay. This could add significantly to the initial crop establishment costs at a time of year when rowers receive no income. However, the partial and parametric analysis indicates that there re benefits from using PAM as part of the crop management cycle. These benefits are from ving water, retaining sediment on-farm and reducing the cost of delving drains. There are ther potential economic benefits including the retainment of phosphorus as a plant nutrient n-farm and subsequent yield increases.

Additionally, the off-site environmental impacts seem …


Diagnosing Crop And Pasture Problems With Detective Doug, Doug Sawkins Jan 2009

Diagnosing Crop And Pasture Problems With Detective Doug, Doug Sawkins

Bulletins 4000 -

There are numerous publications for diagnosing crop and pasture growth problems. Although they are excellent for experienced people, they can be time consuming and possibly misleading for the less experienced.

Many guidebooks assume that the user has already decided that their problem falls into the category covered by their particular guidebook, for example, a disease, pest or herbicide problem.

Guidebooks are often based on plant symptoms. However, in the field, symptoms vary and different problems can have similar symptoms.

This bulletin presents a problem diagnosis method that uses plant symptoms and paddock clues. It can be used to draw up …
