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...

SA grains industry to start groundwork for season 2016.. The South Australian grains industry will launch into the 2016 cropping season when the Grains Research and Development Corporation (GRDC) hosts a major forum in Adelaide in February to support growers through the coming year... Among the subjects to be addressed on day two are positive crop adaptations to climate change; improving productivity on sandy soils; cereal diseases to watch in 2016; barley and wheat variety update; weed and herbicide management; factors influencing nitrogen supply from soils and stubbles; chemical impact on bees; pulse performance maximisation; and the potential of UAVs and robotics to capture useful field data...

"We have measured annual losses of up to 35 kilograms per hectare of nitrous oxide (N 2 O) from around Hamilton... We haven't measured dinitrogen gas losses but, because we're getting these high N 2 O losses, we hypothosise that we might be losing a lot as dinitrogen gas as well.".. "There was a slight response when we applied N at the six-leaf stage, but it wasn't significant...

Top-dressing 100kg/ha at green-bud produced about $800/ha of net income - $514/ha more than applying no nitrogen... Applying nitrogen to canola crops at the correct rate, time and growth stage can increase yields and net income and reduce the potential for nitrogen losses, a study in Victoria's high-rainfall zone (HRZ) has found...
