- Observation Wheat yield declined long term at Wongan Hills with and without nitrogen.
- Observation Wheat yield did not decline long term at Merredin or Beverley.
- Observation Across the three sites, maintaining wheat yields did not require increasing nitrogen rates over time.
- Intervention effect The highest annual ammonium sulphate rate depressed wheat yields in most years at Wongan Hills and Merredin.
