Grains Research And Development Science Highlights 2015-17, Department Of Agriculture And Food Western Australia

All other publications

Western Australian grain production and industry value has quadrupled over the past 30 years, despite declining winter rainfall, more frost and high temperature events, acidifying soils and increasing input costs. Strong evidence links this productivity growth to R&D that has delivered genetically superior varieties, better agronomic practices and more reliable farming systems. Western Australian grain growers are innovators that rapidly adopt new technology which is increasingly sourced from a wider pool of national and global science, research and innovation. Continuing to push the productivity frontier is not only critical to grower’s profitability, it underpins the international competitiveness of ...


Bioenergy And Carbon Farming Opportunities In The Pilbara, Robert Sudmeyer, Kim Brooksbank, David Rogers Dec 2016

Bioenergy And Carbon Farming Opportunities In The Pilbara, Robert Sudmeyer, Kim Brooksbank, David Rogers

Bulletins 4000 -

The Pilbara region covers 270 000 square kilometres of north-west Western Australia. Its main agricultural land use is pastoralism, with beef cattle grazing native pastures. Currently, only 24km2 is under irrigation, with irrigated fodder the principal crop, but this could expand to 100km2. This expansion has the potential to significantly broaden the economic base of the Pilbara.

Irrigation and the opportunities for changing land use and management may facilitate greater participation in the carbon economy by Pilbara land managers. Bioenergy feedstocks could be sourced from purpose-grown crops or agricultural wastes. Carbon farming activities may be facilitated by the ...

Audit Of Wa Agricultural Lime Quality 2013, Chris Gazey Aug 2013

Audit Of Wa Agricultural Lime Quality 2013, Chris Gazey

Bulletins 4000 -

Applying agricultural lime is the most economical way of ameliorating low soil pH in broadscale agriculture in Western Australia (WA). In WA, agricultural lime is usually limesand from coastal sand dunes, crushed limestone from coastal deposits or crushed dolomitic lime (usually marketed as dolomite) from old lake and inland drainage systems. Other sources are Cretaceous chalk and lake bed marls.

WA agriculture is well serviced by lime suppliers, although the quality of lime varies markedly around the State, and cost does not always reflect quality as measured by neutralising value and fineness. Neutralising value and particle size distribution (fineness) are ...

Subsurface Compaction A Guide For Wa Farmers And Consultants, Stephen Davies, Alison Lacey Jan 2011

Subsurface Compaction A Guide For Wa Farmers And Consultants, Stephen Davies, Alison Lacey

Bulletins 4000 -

For plants to grow in agricultural soils, roots and emerging shoots must be able to force their way through the soil. In soils of high strength, this growth is physically restricted. High strength soils may be due to natural soil characteristics and conditions or develop as a result of agricultural practices and may be in layers or throughout the soil profile.

In agriculture, high strength soils commonly occur as a result of compaction. Compaction of agricultural soils can be in the surface (often caused by stock trampling or rain drop splatter) or in the subsurface (usually in a layer at ...


Growing Biserrula To Improve Grain And Livestock Production, Angelo Loi, Natalie Hogg, Clinton Revell, Diana Federenko Jul 2010

Growing Biserrula To Improve Grain And Livestock Production, Angelo Loi, Natalie Hogg, Clinton Revell, Diana Federenko

Bulletins 4000 -

Biserrula pelecinus is a new genus of pasture legume which was developed for commercial agriculture by a team of Perth-based legume pasture scientists in the early 1990s. Biserrula is an annual pasture legume that is found in natural grasslands of the Mediterranean Basin, frequently on acidic soils derived from granite. It was this feature that first caught the eye of researchers who were attempting to develop species that could tolerate the soil stresses of acidity and low moisture-holding capacity. These stresses are common in WA and when they occur together they are problematical for the survival of annual medics and ...

Genetically Modified Canola Trials In 2009, Department Of Agriculture And Food, Western Australia Feb 2010

Genetically Modified Canola Trials In 2009, Department Of Agriculture And Food, Western Australia

Research Reports

During 2009, just over 860 hectares of Roundup Ready® canola were grown in Western Australia enabled by an exemption order under the Genetically Modified Crops Free Areas Act 2003. The aim of the trials was to establish whether GM canola could be segregated from non-GM canola along the WA supply chain, and whether GM canola was agronomically viable for WA farming systems. This was the first time genetically modified canola had been grown on a commercial scale in WA - earlier exemptions for smaller trials had been for variety testing and scientific purposes.

Lucerne Guidelines For Western Australia Principles For Integrating A Perennial Pasture Into Broadacre Dryland Farming Systems, Diana Fedorenko, Perry Dolling, Christopher Loo, Tom Bailey, Roy Latta

Bulletins 4000 -

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.

Identifying Sub-Tropical Grass Seedlings, Brad Wintle, Geoff Moore, Phil Nichols

Bulletins 4000 -

There is considerable interest in growing sub-tropical (or warm season) perennial grasses for out-of-season green feed, especially on the south coast and in the northern agricultural region (NAR). They consist of two types: creeping grasses, which spread by either above ground runners (stolons) or below ground runners (rhizomes) and bunch grasses, which are tufted and do not spread by runners.

The main species sown include Panic grass, Rhodes grass, Kikuyu, Setaria, Signal grass, Digit grass, and Bambatsi panic and are often sown as a mixture, comprising 2 or more species. This bulletin describes how to identify these grasses at the ...

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 ...

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 ...


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 ...

Tree Windbreaks In The Wheatbelt, Robert Sudmeyer, David Bicknell, Neil Coles Sep 2007

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 ...
