This trial aims to address key uncertainties around crop rotation and nitrogen application, providing growers with practical insights to improve decision-making and mitigate risks. This trial forms part of the national GRDC RiskWi$e initiative, which seeks to engage grain producers in identifying and evaluating farm management strategies that carry inherent but uncertain risk-reward dynamics.
Key messages
This is the second year of a five-year factorial crop sequence x nitrogen management trial.
There was a clear yield benefit associated with break crops and fallow.
There was a protein increase associated with increased nitrogen; however, this also caused higher screenings.
