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...

Gary Lang burns wheat stubble before sowing canola to reduce the risk of frost damage on his property north of Wickepin, Western Australia... Since then, Gary has burnt his wheat stubbles immediately before sowing canola... Gary says a hot burn is done one or two days before canola is sown and there is not usually enough stubble in the following wheat crop to warrant burning...

Stubble removal can help reduce frost risk in prone areas.. Reducing stubble loads to 2t/ha can lift yields by 0.6-0.8t/ha if frost hits during the flowering window or early grain fill... The DAFWA model FLOWER POWER is a useful way to compare time of sowing and variety choice, to ensure a wider flowering window to spread the risk of frost and heat stress...

New tests to measure soil health are being developed to help with planning and managing cropping programs... As chair of the GRDC research sub-program for varieties, member of the pulses and oilseed subcommittee and as a board member for the Molecular Plant Breeding Cooperative Research Centre, Jeff was keen to ensure plant breeders had the resources and support to develop new varieties that met future agronomic and market demands... GRDC board member David Shannon, who farms at Kapunda, SA, says Jeff was a likeable, intelligent and quietly spoken man who had a clear understanding of grains industry issues: "He was a true gentleman and was prepared to speak out on behalf of others when necessary," David says...

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 that combine targeted local extension to address gaps in motivation, attitude and ability with on-farm field trial activities designed in collaboration with local farmers and advisors in mallee (including Victoria, NSW and SA) to fill gaps in local knowledge and understanding...

Key points controlling summer weeds is the most effective way to conserve soil moisture during the summer fallow period... summer grazing can damage soil in the surface layers, but does not reduce crop yields provided summer weeds are properly controlled and at least 2t/ha of cereal stubble or 70 per cent stubble cover is maintained... Only one in 13 experiments showed an improvement...

Dr Neil Fettell, University of New England (UNE) and NSW Department of Primary Industries (NSW DPI), and Ian Menz, NSW DPI have investigated the impact of grazing on soil properties, water dynamics and crop yield in a no-till, controlled-traffic system... The eight treatments are each replicated four times and the variables are: grazing intensity using adult sheep (nil, moderate or heavy); stubble amount (as is, or added or removed depending on the season); and weed control (all herbicide or partly reliant on grazing)... Dr Fettell says the results from the two trials support earlier research and suggest that stubble is most beneficial where the summer rainfall intensity is high, unstable soil surface structure results in low infiltration rates and slopes are enough to encourage runoff...
