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.
