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.

Supporting a more deliberate and logical approach to decision making

Field trials compare risk and rewards for nitrogen decision approaches

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.
