Field Research & Agronomy

AIM:

Part of a series of trials to assess wheat response to N and P fertilizer applications under different conditions, soil P stores and soil PBI across the wheat belt.

For further details contact your local Area Manager or the Summit Research Team

CONCLUSION:

• Both Phosphorus (P) and Nitrogen (N) combined significantly to improve wheat yield.
  
• Treatments responses were consistent with Summit trials over many years in the area.
  
• A P recommendation of 12-18 kg/ha and N recommendation of 30-60 kg/ha optimised yield and grower returns.
