The nitrogen bank for higher yields and lower emissions

May 20, 2025

Analysis of the impact of nitrogen decision-making systems indicates that yield does not need to be sacrificed to achieve environmental gains

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.
