Recent research suggests that the adoption of a nitrogen bank (N-bank) approach to nitrogen management, where nitrogen (N) is replenished and maintained at sufficient levels to achieve water-limited yield potential in most seasons, is less risky and more profitable than conventional N strategies.
This research component of RiskWi$e compares various N management strategies to determine their legacy effects on subsequent crops. A key focus of the research is on the performance of organic, compared to mineral, N banks, with both on-farm and small plot trials set up in 2023 and designed to be monitored over several years.
By delivering large-scale on-farm trials, this research aims to inform and improve risk-reward understandings of on-farm N management decisions and to support evidence-based practice change.
