Nutrient Use Efficiencies at the Springbank Demonstration Site
The trial site; potatoes in these rows were treated with the nitrification inhibitor
The rising cost of inputs has growers searching for ways to enhance nutrient use efficiency and understand its impact on pack-out and yield. A previous trial (read more here) at the PotatoLink demonstration site in Springbank (Victoria) explored how farm practices impact the effectiveness of biologicals, including fungicide application, soil nutrient availability, and fertiliser use. The positive results from that trial, including improvements in tuber size, quantity, and specific gravity, shaped the objectives for this new trial.
This trial (carried out between November 2023 and March 2024) focused on the impact of specific inputs on yield and quality. The study was divided into three trials using the processing variety, Innovator:
Impact of nitrification inhibitors
Effect of potassium sources - Sulphate of Potash (SOP) vs Muriate of Potash (MOP)
Impact of humic acid
