Best bet management of nutrition on ameliorated non-wetting soils in the Geraldton Port Zone - Eneabba 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
  • This site was unresponsive to nutrient treatments in 2017
  • Treatments were adjusted to reflect grower standard practice due to drier than normal conditions at the beginning of winter.
