Could your OSR be leaving yield behind? π±
When margins are tight, every extra percentage point matters.
Proven results in oilseed r**e with POLY4:
+4.6% seed yield uplift across 67 OSR trials compared with standard NPK fertiliser programmes.
In a peer-reviewed scientific study, statisticians analysed data from field trials comparing POLY4 fertiliser programmes with standard NPK programmes across different environmental conditions. In 67 replicated oilseed r**e trials, POLY4 programmes delivered a statistically significant 4.6% increase in seed yield compared with NPK programmes.
POLY4 is made from the naturally occurring mineral polyhalite, which is packed with essential nutrients needed for optimum crop performance.
