Getting nitrogen supply ‘less wrong’ more often
March 13, 2025
Getting the N supply to a crop ‘right’ in any one year is incredibly difficult, so that in any one year it is often ‘wrong’. So, given this uncertainty the question is, can we find an N supply target (i.e. soil mineral N and fertiliser to be applied) that we could aim for year-in, year-out, that means we get the N rate we apply ‘less wrong’ more often.
Nitrogen fertiliser decisions – the good, the right and the risky
March 7, 2025
It is difficult to make the ‘right’ N decision every year, but ‘good’ decisions are relatively easy and are more likely to be ‘right’, particularly when reviewed over several years.

Field trials compare risk and rewards for nitrogen decision approaches
August 28, 2024
A network of 43 small plot and paddock scale trials are quantifying the risks and rewards of different nitrogen management decisions over multiple years. These trials will characterise the yearly variability in response to N but importantly also measure carryover of residual N from one year to the next.
Nitrogen Decision Making Approaches
August 27, 2024
Applying fertiliser is considered a ‘risky’ decision because of uncertainties associated with a lack of return on investment in the year of application, negative yield responses to applied N or losses of N. A range of different approaches can be applied to balance these risks and rewards.
