Western Australian grain growers may need to consider adjusting 2014 nitrogen fertiliser strategies due to the influence of high stubble loads and a dry summer and autumn on plant available nitrogen in the soil... Mr Ryan suggested growers use these results and assess stubble loads to determine if additional fertiliser was required, and consider adjusting their nitrogen application method at seeding time or using split (separate) nitrogen applications which could decrease any risk of low nitrogen availability... "Knowing your current soil nitrogen status; stubble density; stubble quality (including the amount of nitrogen relative to carbon); and soil moisture content can help you manage fertiliser applications and rates to ensure that adequate nitrogen is supplied to the crop," he said...

Consider rhizoctonia seed treatments to boost cereal yields.. Daniel says the take home messages from the trials are that in-furrow banding of fungicide 2-3cm below the seed can provide protection to crop seminal roots and surface banding behind the press wheel can protect the crown roots... Daniel says there are some promising fungicide banding treatment options for rhizoctonia in the pipeline that performed well in the trials...

The new age of soil phosphorus testing is.. Extensive testing over recent years and trial analysis this year have demonstrated that the DGT test offers considerable improvement in predicting soil available P levels on many cropping soils in south-eastern Australia... Dr Mason says the DGT test is a plastic device that uses an iron oxide gel as a P sink, which attracts available P through a membrane...

New national initiative to help grain growers adapt to climate change.. Through the Australian Government's climate change initiative, Australia's Farming Future - Climate Change Research Program (CCRP), the Department of Agriculture, Fisheries and Forestry (DAFF) and the Grains Research and Development Corporation (GRDC) have commenced a demonstration program called the National Adaptation and Mitigation Initiative (NAMI)... GRDC Managing Director Peter Reading says the initiative will play an important role in equipping primary producers with tools to adapt and adjust to the impact of climate change and to manage their emissions...

Over the next year, new research will provide Western Australian growers with information to compare the cost effectiveness of purchasing different information layers for variable rate technology (VRT) zone application maps... In addition to a comprehensive literature review, knowledge and experiences from growers, agronomists and precision agriculture practitioners about the benefits and drawbacks of each information layer will be incorporated into the study... "With seeding well underway in the west, decision making about the cost effectiveness of purchasing different map layers for variable rate technology (VRT) zone application will be top of mind for many growers," Mr White said...

For grain growers who thought they were already shovelling out the nitrogen every year, 's a sobering thought... Dr Angus says the rate of decrease appears to be linear over 10 to 30 years but after about 50 years, turns out to be curved and soil N eventually flat-lines... Dr Angus says it is likely that gross margins underestimate the profitability of the mixed pasture-crop system by not accounting for other synergies between pastures and crops...

Studies funded by the Grains Research and Development Corporation (GRDC) are investigating whether crop stubbles offer useful amounts of phosphorus (P) to plants during the growing season... The research is being conducted by the University of Adelaide which plans to develop a better understanding of how P is released from stubble and then taken up by subsequent crops... ENDS Caption: University of Adelaide research student Sarah Noack is involved in a study which plans to develop a better understanding of how P is released from stubble and then taken up by subsequent crops...

The Grains Research and Development Corporation (GRDC) is on track to continue its substantial investment into northern grains research following last week's release of the GRDC External Investment Plan 2015-16 ... Key areas that will attract GRDC funding include short-term Grower Solution Group (GSG) investments targeting important localised research, development and extension (RD&E) issues; agribusiness trial extension networks; research and farm business updates; and an extensive range of agronomic and farming systems management projects... "We will continue to invest in areas that can help drive profitability improvements for northern growers like soil and crop nutrition, weed seed and herbicide resistance management, break crops, crop rotations, pests, disease, nematodes, frost management and regional research capacity...
