Mr Murray’s research focused on variable rate application technology in the New Zealand aerial topdressing industry.A case for technology assisted fertiliser application was developed. This involved investigating the field performance of conventional and enhanced flow control systems and the effect of variable rate application on hill country pasture production.The research showed that automating the fertiliser flow control system can reduce off-target fertiliser application. Increased profitability should result when managing fertiliser inputs, based on the potential pasture production outputs of the farmland.
