GRDC 2014 Research Summaries

Registered items

About 8 million hectares of Western Australia (WA) were inherently deficient in micronutrients (copper (Cu) and zinc (Zn) and molybdenum (Mo) and to a lesser extent manganese (Mn)... If untreated can result in widespread and severe nutrient deficiencies, including those caused by poor supply or use of micronutrients... There is also increasing concern that micronutrient supplies from the soil may no longer be adequate for current cropping systems that are more productive, more intensive and more reliant on supplies of fertiliser N and P. These concerns are often coming from districts where...
GRDC Taxonomy:
The aim of the project is to increase farm profitability through the sustainable adoption of broadleaf crops in all of the major cropping regions and systems of Australian agriculture... These are: 1) A total of 9 Best Management Practice Training Manuals will be produced and/or revised over the life of the project, 2) Development of and maintenance of a purpose built E-library consisting of easily accessible resources for growers, advisors and researchers, on the sustainable and profitable production of broadleaf crops... Increasing the confidence of growers and advisors in their ability ...
GRDC Taxonomy:
The rising incidence of insecticide resistance in invertebrate grains pests is concerning, particularly at a time when access to several active compounds is being threatened... Several important pests have developed resistance due to the over-use and heavy reliance on agri-chemicals... GPAC will act as a think-tank and will be sufficiently resourced through the appointment of an Executive Officer at the University of Melbourne so that issues around resistance management, knowledge gaps and control opportunities are tackled in a rigorous manner rather than as a reaction to issues that arise...
GRDC Taxonomy:
The project is aimed at evaluating the distribution and economic importance of weeds to Australian grain growers across a range of regions, crops and weed types... The project will consider the range of practices used for weed management and the interaction between weed management challenges and grower use of practices such as no-till and stubble retention systems... In providing the foundational data on grower practice on the economic impact of weed management in no-till farming, repeating this study will provide credibility and accuracy informing the weed impact study which GRDC has indi...
GRDC Taxonomy:
Australian grain growers have progressively adopted a number of best management practices in order to minimise soil tillage, which is one of the main causes of soil erosion, soil compaction and soil organic matter loss... Little is known about how the increased application of herbicides affects soil biota and soil functions that sustain crop growth and ecosystem services such as crop residue turnover, water holding capacity, soil carbon storage and nutrient cycling... The project will address current knowledge gaps regarding the impact of herbicides on soil biota in all three growing regio...
" eXtensionAus Field Crop Diseases Learning Network.. Australian grain producers are expected to benefit from a US-based online platform for sharing agronomic research and information  a first for Australian agriculture  thanks to a new trial... The 15-month pilot will test two learning networks in the grains industry: a field crop disease network (led by DEPI Victoria); and a crop nutrition network (led by DPI NSW), involving researchers, extension practitioners, agronomists and producers across Australia...

Seasonal climate forecasts hold the promise of better farm management in the face of Australia "s variable climate... , the project will try and quantify the Spayoff time for the use of a seasonal forecast: how many years should a farmer use a forecast in order to have a high probability of a better outcome than if no forecast were used The value of POAMA forecasts will be assessed against the baseline of not using a forecast, and against using a simple SOI-based forecast where applicable... To aid harvest, chemical defoliants are used to remove leaves, and this process works better at war...

Researcher's Name: Mr Cam Nicholson Organisation: Southern Farming Systems Email: nicon@pipeline.com.au Phone: 03 5258 3860 Fax: 03 5258 3860 Project Code: SFS00028 Contract Start: 1/1/2014 Contract End: 12/31/2017.. While significant work has already been done on this topic, Grain and Graze 3 will focus on getting the most out of stubbles, grazing canola in winter, understanding what environmental conditions post grazing lead to grain yield loss and the impact of grazing on weed densities... Finally Grain and Graze 3 will tackle the complex issue of planning and implementing integrated sy...
" Understanding the molecular basis for desiccation tolerance of rhizobia for improved survival on seed.. Survival of rhizobia can be poor and varies depending on the rhizobial strain and inoculant formulation... The project will engage with Professor Philip Poole, an expert in rhizobial molecular physiology at the John Innes Centre, Norwich, UK. Professor Poole will facilitate training of project personnel in established techniques for isolation of mRNA from rhizobia and subsequent micro-array analysis...

" Workshop to research and develop methodologies for the measurement of greenhouse gas emissions from canola production.. Before 2017 the industry must satisfy the EU reporting requirements that Australian canola provides greenhouse gas emission savings of at least 50% (compared to emissions from use of mineral diesel)... To meet the threshold of a 50% saving in greenhouse gas emissions a different measurement methodology is required.A national workshop for the canola industry's key stakeholders is proposed to be held in early 2014 in order to map out a way forward for the industry that w...
