POLY4

13/10/2026

🌱 Fertilisers help farmers grow the crops that feed the world. But as farming faces new challenges, how efficiently we use those nutrients matters more than ever.

This Global Fertiliser Day, fourth-generation Hampshire farmer Matt Culley shares how POLY4 has become part of his approach to crop nutrition, helping him use nitrogen more efficiently and build resilience on his farm.

After three years of using POLY4, Matt explains why sulphur, soil health and making every application count matter today, and for the generations that follow.

🎥 Hear Matt’s story.

Not your average competition prize 🚜

Congratulations to Elveden Farms!

The farm has now received its half-load of POLY4 after winning our Cereals 2026 prize draw at Diddly Squat Farm. 👏

Thanks to our partner Thomas Bell Fertiliser Importers for making it happen, and to our Technical Sales Specialist, Scott Garnett, who will be supporting the farm as it gets started with POLY4, our natural mineral fertiliser that supplies potassium, sulphur, magnesium and calcium in a single product.

Could your OSR be leaving yield behind? 🌱

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.

Today we're celebrating and the people who keep British agriculture moving.

From soil management and nutrient planning to drilling, crop monitoring and harvest, farming is a constant cycle of hard work, adaptation and problem-solving.

We're fortunate to work alongside farmers facing these challenges every day. We understand the pressures that come with producing food, managing costs and planning for an increasingly unpredictable future.

If our role can be to help make some of those decisions a little easier and support more efficient use of nutrients on farm, then that's something we're proud of.

To everyone sharing their story today, thank you for helping connect more people with modern farming and the work that goes into producing our food.

"By using POLY4 in a regenerative system, I'm building resilience in the soil. That means when I pass something on to future generations, they'll inherit soil that has accumulated value."
– Ben Taylor-Davies, Herefordshire farmer

See how Regen Ben compared a regenerative fertilisation programme based on POLY4 with a conventional MOP and TSP programme on his farm.

As part of York and North Yorkshire Combined Authority Local Growth Plan's Food and Farming initiative we're excited to be on home turf this week at the Great Yorkshire Show

We're looking forward to sharing the story of POLY4 and the Anglo American Woodsmith Project, and how this great Yorkshire project will help feed the world.

As well as this, our Soil Science Principal, Kathryn Bartlett, will be taking part in a panel discussion on:

Nitrogen Use Efficiency (hosted by Farmers Science Network)
Agri-Innovation Village at 11:00am on Tuesday.

With several days already sold out, it's shaping up to be a fantastic event.

Come and say hello – we'd love to see you there!
