Yield is just the start

POLY4 takes you further - improving quality, increasing market appeal and driving better returns every season.

POLY4 enhances output for your farm in a number of ways:

Increased yield

POLY4-based fertiliser plans can offer noticeable yield increases compared to standard approaches.

Better crop quality

POLY4 improves the crop's overall quality helping you deliver more of what the market values - and less of what it doesn’t

Increased returns

POLY4 improves yield while reducing other wasteful practises helping you achieve more for the efforts made during the growing season.

Yield improvement highlights taken from our extensive global trials programme.

The programme includes trials across the globe (over 2500+ field trials since 2013).

Simplify crop nutrition with POLY4

With POLY4 you can simplify your crop nutrition programs. It provides four macro nutrients required for growth (Potassium, Sulphur, Magnesium and Calcium) - even if they’re sensitive to chloride.

High-value crops like grapes, potatoes or avocados need extra care - and often, extra cost.
POLY4 lets you reduce the need to apply expensive inputs such as fertigation or granular NPK.

With POLY4 you get simple and more efficient nutrition.

POLY4, a seamless integration into dry blends

We don't claim that POLY4 solve all your issues when it comes to crop nutrition but it does works seamlessly with other inputs meaning you can combine it into many blends, reducing the number of spreads, saving your valuable time and ever increasing fuel costs.

"The results of the POLY4-based programme were remarkable. I could achieve the same level of yield with significantly reduced cost of inputs"
