To determine whether reducing fertiliser rates on older ratoons (3R onwards) will maintain productivity, reduce grower costs and reduce the risk of applied nitrogen leaving farms.
To develop a site-specific nitrogen reduction rate that the grower can implement on their blocks that are irrigated with underground water high in nitrates.
To calibrate GDots to sugarcane growth to give growers more confidence to use them for irrigations scheduling. To encourage the adoption of GDots as an irrigation scheduling tool.
