Long-term phosphorus trial locations
Aims

To identify the most economical rate of phosphorus usage in a southern Mallee cropping system over time. 

Key messages
  • The application of P improved the yield (especially barley) and soil P content (Colwell P).
  • Soil P balance doubled when high P rates were applied.
  • Responses to P applications above 6kg P/ha are rare and extra expense would not be justified in the Mallee.
