Results
Of the 3 Polysulphate application rates tested, the best result was achieved when Polysulphate was applied at 100 kg/ha. This resulted in a yield increase of approximately 8% (0.35 metric tons per hectare). Based on a market price of £180/metric ton this represents an additional return of £62.28 per hectare.
