Polysulphate increases Winter Wheat yield
5.4
UK 2018

Key Conclusions
This trial showed that Polysulphate fertiliser improved the overall winter wheat yield by 5.4%, or 354 kg/ha.
At the time of the trial, the farmer reported that the average price for grain was £170/t. This means that Polysulphate fertiliser improved the return for the farm by £60.18/ha. When the cost of Polysulphate fertiliser is removed (100 kg/ha), the return on investment for this trial was £44.18/ha.
Objective
This UK winter wheat (Triticum aestivum) trial investigated the effect of an autumn application of Polysulphate fertiliser on winter wheat. Specifically, the trial examined the increase yield through crop establishment.
With UK soils being low, or critical, for sulphur 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.

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. The trial treatment plot also received 100 kg/ha of Polysulphate.

---|---|---|---|
ha | kg/ha | kg/ha | |
Polysulphate (Field A) | 1.92 | 250 | 100 |
Control (Field B) | 1.92 | 250 | - |

Results
When compared to the control plot, the area which received Polysulphate showed an increase in yield of 354 kg/ha, a 5.4% yield increase.
