Best bet management of nutrition on ameliorated Non-wetting soils in the Geraldton Port Zone - Marchagee locations

To determine the most effective way to apply nutrients (granular, banded, top dressed or liquid) on non-wetting soils after amelioration, in the Geraldton Port Zone.

Key messages
  • Wheat yields were low, around 1 t/ha, as a result of low growing season rainfall in 2017.
  • Treatments were adjusted to reflect standard grower practice due to drier than normal conditions at the beginning of winter.
  • This site was unresponsive to nutrition treatments in 2017.
