Project Overview
Long-Term Cropping System Insights from Gol Gol
This long-term trial at Gol Gol, NSW, examined how break-crop choice and nitrogen (N) fertiliser rates interact within diverse Mallee cropping systems across north-west Victoria and far western New South Wales.
Over six years, the trial compared multiple legume and non-legume break crops followed by wheat and barley under a range of nitrogen fertiliser rates. It provides local, practical evidence on crop yield, grain protein, nitrogen balance, and profitability, showing that rotation choice has a greater influence on system performance than increasing fertiliser nitrogen alone. The results highlight that nitrogen is most effective when it complements a well-chosen rotation rather than replacing its benefits.
