Assessing standard crop fertilizer practice against new strategies. This trial assesses the response of barley under a factorial nitrogen (N) and phosphorus (P) fertilizer application trial design in the Merredin area to increase recognition of the value of optimal N and P to barley yield, grain quality and profitable returns. The trial provides an important focal point for investigating P response, particularly, due to the soil P analysis indicating luxury soil P status at the surface (0-10 cm) but deficient below.
