Over the last decade there has been a large shift by Mallee farmers to adopt stubble retention systems with no-till in their farming systems... Key factors include: Growers that have been utilising stubble retention and no-till farming systems for many years are facing production and profitability constraints and have general concerns that their farming system as a whole is not performing as well as it should be, relative to more traditional farming systems involving low groundcover and higher erosion risks... Project outcomes will be achieved by employing a range of project activities tha...
GRDC Taxonomy:
New stream, assay system to be developed, screening and characterisation of isolates and field trials, with decision points in Dec 2014 after initial glasshouse assays and March 2017 to engage commercial partner... The major foci of this project are to screen and identify elite disease-suppressive microbes for cereals and nodulation-enhancing beneficial microbes for legumes... The Program will consult and work with potential commercial partners, eg Novozymes Biologicals, Becker Underwood, New-Edge Microbials, ALOSCA Technologies, thereby providing mechanisms to ensure communication of rese...
GRDC Taxonomy:
The sources of risk in agriculture are numerous and diverse... There have been a number of studies identifying various aspects of production risk due to seasonal variation; the key issue this project is addressing... The risk management framework requested will be an effective means of utilising this past research (eg Zheng et al 2012, Hammer and Stone 1998) and transforming it to meld with research from this project...
Farmers throughout southern Australia continue to seek improved conservation farming strategies, including increased levels of residue retention, reduced soil disturbance, and greater rotation diversity... CSIRO has been monitoring changes in the water balance on the trial since then, and so far we have demonstrated that early crop termination (as part of a cover cropping practice) can increase the risk of dryland salinity under some situations... Increased levels of residue retention have had little impact on the water balance in the short term (6 years), and so farmers can adopt this pra...
The NSW Department of Primary Industries, the Grains Research & Development Corporation (GRDC) and Australian agribusiness have joined forces with the US eXtension Foundation (affiliated with the USDA) to pilot the eXtension online service delivery platform in Australia... eXtension is an interactive online knowledge sharing and learning environment delivering the latest research information to US producers... Features of eXtension include a collaborative publishing, educational tools, a webinar function and an SAsk An Expert service...
Pre-breeders simply don "t have the resources to evaluate entire germplasm collections... Methods are required to identify trait specific best-bet subsets of germplasm of sizes that economically feasible to evaluate... The project proposed is to further refine the FIGS algorithms so that their predictive power is improved and deploy them to identify relatively small best-bet subsets of germplasm for cereal and pulse crops that will increase the probability of capturing rare alleles for key traits...
GRDC Taxonomy:
The project will support the national effort to effect a step change in the management of soil acidity across the Southern Region by co-ordinating and delivering a South Australian component... Soil acidity is now recognised as a major land degradation issue by growers, state and federal government and RD and E providers... The causes of soil acidity are well understood as are methods of treatment the adoption of practices to treat acid soils are well below the required level to maintain soil health...
GRDC Taxonomy:
The Australian grains industry is facing economic loss due to regulation of existing pesticides and associated application due to continued adverse spray drift events and lack of current suitable data to support current best practice... There is also potential increased regulation of pesticide products due to current pesticide use practices and stewardship including residue management and spray drift... Efficacy studies will be conducted on grass and broadleaf weeds using medium and coarse spray qualities so growers will be confident that weed control will be maintained with these sprays...
GRDC Taxonomy:
The assessment will involve comparing past POAMA forecasts with the historical record and improving our understanding of how the frequency of these events changes with large scale drivers of atmosphere and ocean circulation such as ENSO, the IOD, blocking, and SAM. We will work with farmers, their advisers, and extension providers to incorporate forecasts of the likelihood of frost and heat events into their risk management... We will assess the utility of forecast information at seasonal time scales and outline strategies to manage temperature extremes... The tests would also be carried o...
GRDC Taxonomy:
Project WAN00020 highlighted that dry seeding in Western Australia can increase productivity, predominately, in low to medium rainfall years but also increases risks with weed control, frost and heat stress... Setting up the paddock: Management of soil water availability through fallow management, rainfall through autumn and summer and weed control... Late season Risks: Agronomy of dry seeding to avoid heat stress, frosts and to maximise water use efficiency...
