adequate nitrogen

Catalogue: GRDC Media
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...

Southern Farming Systems chief executive officer Jon Midwood says there is scope for late-season nitrogen application to become more popular, given a soft finish to the season... "Some of the sites we trialled already had adequate nitrogen because of high residual levels, or the grower had applied more nitrogen prior to GS32," Mr Midwood says... "Also spreading widths are getting wider and there may be a case for considering liquid fertilisers because they can be applied through a boom-spray at the correct width, compared to a spinning disc spreader which can be limited by wind conditions and machine set-up," Mr Midwood says...

On-farm trials at Corrigin, WA, exploring wheat protein responses to nitrogen applications at different rates and times... Risk-averse growers tend to be conservative in their use of nitrogen... Split application "Split application improves the recovery of applied nitrogen, and if some of your nitrogen is applied after the beginning of stem elongation you are more likely to get a response in protein than if all the nitrogen is applied at sowing," Dr Milroy says...
