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

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 ...

A Pilot Study Of Sheep Disease Surveillance In Western Australia, Roy Butler Sep 2016

A Pilot Study Of Sheep Disease Surveillance In Western Australia, Roy Butler

Contributions to Conferences

A pilot study of sheep disease surveillance was conducted in 2014-2015 on four farms in the eastern wheatbelt of Western Australia. The participants observed their sheep, sufficiently closely to notice disease, at least every second day. Most of the disease syndrome reports related to fewer than five sheep, demonstrating that farmers noticed problems in individual sheep, and not only in groups of sheep. Of a total of 66 disease syndrome observations reported over 12 months, the three most frequently occurring syndromes were found dead + sudden death (combined), skin lesions, and lameness.


Agronomic Options For Profitable Rice-Based Farming System In Northern Australia, Siva Sivapalan Sep 2016

Agronomic Options For Profitable Rice-Based Farming System In Northern Australia, Siva Sivapalan

Contributions to Books & Books

Minimum air temperatures less than 15°C had biggest impact on varietal performance. Cold damage during the months of June and July warrants selection of varieties with cold tolerance for this environment, especially for the aerobic rice system. Ponded water has 4-8°C advantage over the air temperature, thus providing some protection against such cold damage. This has resulted in higher yields under flooded system. Planting dates, varying from late-February to late-May, were found to play a crucial role for plants to escape the low temperature damage at critical growth stages. Among the varieties tested, selected tropical varieties yielded higher ...

Propagating Jujubes, Rachelle Johnstone Jan 2016

Propagating Jujubes, Rachelle Johnstone

Research Reports

Jujubes can be propagated by various methods such as wedge/cleft grafting, whip grafting and bark grafting as well as budding. Local propagators have better success with budding but find that wedge grafting leads to a stronger tree. Most of the latest research into propagation is in micropropagation and tissue culture however this technique is mainly used for research and breeding new cultivars and not in a commercial capacity. Grafting can be more of an art than a science. Much of the success of grafting depends on not only performing a technically correct graft but performing the graft at the ...

Groundwater Trend Analysis And Salinity Risk Assessment For The South-West Agricultural Region Of Western Australia, 2007–12, G Paul Raper, Russell Speed, John Andrew Simons, A L. Killen, Andrew Blake, A T. Ryder, Rosemary H. Smith, Grant Stainer, L Bourke

Resource management technical reports

Dryland salinity is a hydrologically driven land degradation hazard in the south-west agricultural region of Western Australia (WA). Shallow-rooted annual crops and pastures transpire significantly less water than the native vegetation they replaced, leading to an increase in recharge, rising groundwater levels and the development of shallow watertables in areas where often none existed previously. Rising groundwater levels mobilise soluble salts, naturally stored at high concentrations in the regolith. These salts can be concentrated in the root zone of vegetation by evapotranspiration.

Pasture Condition Guide For The Kimberley, Kathryn Ryan, Elizabeth Tierney, Paul Novelly, Robert Mccarteny

Bulletins

This interactive guide has been produced as a tool for assessing pasture condition over a range of pasture types in the Kimberley. 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.
