Best bet management of ameliorated non-wetting soils of the Geraldton Port Zone - Irwin locations
Aims

To determine the best way to apply nutrients and increase nutrient uptake on non-wetting soils after amelioration in the Geraldton port zone.

Key messages
  • The treatment plots with low or no potassium were observed to have less vigour (visual assessment) and plant density from emergence.
  • High potassium treatments had lower screenings and higher yields independent of the rate of nitrogen applied.
