Field Research & Agronomy

AIM:

Expanding the series of eastern wheat belt trials assessing how wheat responds to N and P fertilizer applications under different conditions by the addition of K.

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

CONCLUSION:

• Differences in yield between P treatments were significant and consistent with Summit trials over many years in the area.
  K application should be a consideration depending on results of soil testing.
  
  
• A P recommendation of 8-10 kg/ha and N recommendation of 30-60 kg/ha optimises yield and grower returns.
