Polysulphate Winter Wheat Trial in the UK
5.4
UK 2018
5.4
Key Conclusions
This trial showed that Polysulphate fertilizer improved the overall winter wheat yield by 5.4%, or 354 kg/ha (316 lbs/acre or approximately 5.3 bushels/acre).
Objective
This UK winter wheat (Triticum aestivum) trial investigated the effect of an autumn application of Polysulphate fertilizer on winter wheat.
With UK soils being low, or critical, for sulfur deposits and plants needing S to take up nitrogen, this experiment is designed to test whether Polysulphate improves residual N uptake by the plant and improves establishment of the crop.
Trial Details
Treatments
The field was split into two plots. Both the control, and the Polysulphate plot received base fertilizer (0-20-30) applied at 250 kg/ha (223 lbs/acre). The trial treatment plot also received 100 kg/ha (89 lbs/acre) of Polysulphate.

Results
When compared to the control plot, the area which received Polysulphate showed an increase in yield of 354 kg/ha (316 lbs/acre or approximately 5.3 bushels/acre), a 5.4% yield increase.
Polysulphate applied at 100 kg/ha resulted in an increase in wheat yield of 354 kg/ha (316 lbs/acre or approximately 5.3 bushels/acre).
