Managing your fertiliser dollar in wheat, barley and canola locations
Aims
  • To assess simple nitrogen management strategies to determine the best return on investment from fertiliser nitrogen applications.
  • To determine within a crop rotation (wheat, barley and canola) where was your fertiliser dollar best spent over a number of seasons.
Key messages
  • In wheat an application rate of 20 kg N/ha in-season was sufficient to achieve the highest yield at Hart in 2017. However, it was the 80 kg/ha treatment which maximised yield and protein to achieve the best return on nitrogen fertiliser invested.
  • For barley an application of 40 kg N/ha was adequate to produce the highest yield and quality within the trial.
