A best bet managment of ameliorated non-wetting soils for the Geraldton Port Zone locations
Aims

To determine what is the best way to apply nutrients on non-wetting soils after amelioration in the
Geraldton port zone (GRDC RCSN project).

Key messages
  • Low potash treatments were easily observed in the lupin rotation (2018). They had less vigour and plant biomass and yielded significantly less than the other treatments.
  • The low potash treatments were also low yielding in the 2017 wheat phase.
