Are you sure of your nitrogen supply in 2014?

Plain text source: 
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...
