A perfect fit for sustainable farming

POLY4 supports efficient, low-impact farming - so you can keep farming into the future.

From the earth, for the earth

POLY4 is a natural mineral fertiliser taken from the earth before being applied back on the land by farmers - keeping them productive without impacting their land or efforts negatively. A single natural mineral containing four key nutrients in plant available form it works in harmony with the soil, causing no negative effects to its biology. It helps improves nutrient use efficiency through balanced nutrition and is certified for organic use in a number of regions.

The ways POLY4 supports lower-impact farming:

Organic

POLY4 is qualified for use in organic farming in many countries around the globe.

No negative impacts on the soil

Works in harmony with soil and causes no negative effects to its biology.

Lower potential of nutrient leaching

POLY4's efficient use of nutrients - both its own and those found in the soil - and its ability to improve soil structure means nutrients are less likely to be wasted and cause dangerous run-off.

Improves nutrient use efficiency

Improves nutrient use efficiency through balanced nutrition.

A perspective from regenerative farmer Ben Taylor-Davies.

”On my farm in Herefordshire I set up a regenerative fertilisation programme for potatoes based on POLY4 and compared it to a conventional programme based on MOP and TSP. The results of the POLY4-based programme were remarkable. I could achieve the same level of yield with significantly reduced cost of inputs.

Moreover, when analysing soil samples, I could see a huge positive difference in the amount of soil species in favour of the POLY4-based programme, meaning that the soil was cycling far more nutrients to the plant naturally.”

"This product would fit perfectly within organic farming."
