Simple programmes for winter crops with great results

Results of a broad trial programme in France (2016-2024)

From 2016 to 2024, we ran field trials across France to see how POLY4 could improve standard NP fertiliser programs - 27 trials on winter wheat, 8 on oilseed rape.

POLY4 addition gave crops all of the K and S they needed and substantially improved yields, setting up new standards of success.

Winter wheat with POLY4

Results are medians of 27 field trials in France conducted in 2016-2024. Protein content was measured in 21 trials. All treatments in the same trial received equal amounts of N and P. Win rate – ratio of number of trials with yield improvement following POLY4 application to total number of trials.

Oilseed rape with POLY4

Yield results are medians of 8 field trials conducted in different regions of France, harvest 2022. Oil content was measured in 6 trials and is presented as arithmetic mean. All treatments in the same trial received equal amounts of N and P. Win rate – ratio of number of trials with yield improvement following POLY4 application to total number of trials.
