Treatments
Grower standard practice consisted of 135 kg N/ha in the form of urea, 45 kg P2O5/ha in the form of DAP and 135 kg K2O/ha in the form of KCl. The trial tested 2 Polysulphate treatments which were duplicates of the grower standard practice, but with the K portion being made up of 50:50 Polysulphate and KCl, or 100% Polysulphate.
