Measuring the effect of residual P locations
Aims
  • To measure crop response in a field trial at Minnipa to different fertiliser rates over time, with soil P levels measured annually as Colwell P.
Key messages
  • Despite three years of above average rainfall, a red calcareous sandy loam at Minnipa with soil phosphorus reserves of 27 mg/kg of Colwell P has not required any added P fertiliser for maximum cereal grain yields.
