Managing N application in uncertain seasons locations
Aims

To optimise wheat and barley protein by better understanding response to high nitrogen rates in a given season.

Key messages
  • Decision support tools such as ‘Select Your Nitrogen’ and ‘CliMate’ can help decision making with in-season nitrogen applications.
  • In a decile 1 year there are limited benefits from in season nitrogen applications when yield does not increase with additional N fertiliser.
  • Better economic returns result when both yield and protein are increased in higher decile years.
  • It is important to understand production goal and the potential economic return of your nitrogen inputs.
