Last year CSBP conducted trials in Dandaragan and Trayning to investigate the effects of P distribution at seeding time on crop yields and gross margins.

View the results summary sheet for information on these two trials. 

Key messages:

  • Agras provides more than double the number of active P sites in the drill row compared to MAP
  • P supplied by Agras was more profitable than P supplied by MAP at rates lower than 50kg/ha
  • Select a fertiliser product such as Agras, to maintain fertiliser rates above 50kg/ha to maximise profit
  • A reduction in upfront costs for the same rate of applied P can result in reduced profit
