A PotatoLink demo with grower Coby Badcock tested four fertiliser strategies on a Tasmanian crop, comparing high-input vs sap-guided approaches. The results offer insights into nutrient timing, efficiency, and cost-effectiveness—proving that more fertiliser doesn’t always mean better yield.

A new demonstration trial in North Motton, Tasmania focused on optimising fertiliser practices in potatoes by evaluating varying rates, timings (pre-spread, at planting, and top-dress), and approaches (crop sampling and conventional programs) to improve grower profitability and potato marketability.
