To fine-tune the fertiliser requirement of yielding zones in different paddocks.
The higher yielding zone of the paddock did not require more DAPSZC than the lower yielding zones. Such on-farm experiments have a great potential to inform and improve paddock management for increased profits and environmental outcomes by using inputs more wisely.
