POLY4 is the natural, multi-nutrient fertiliser helping farmers grow more sustainably, profitably, and resiliently.
Rising pressures are making farming less profitable and more inefficient, threatening global food security. The gap between effort and reward is widening. And while other fertilisers can add to the problem, POLY4 is different.
POLY4 is made from the naturally occurring mineral
polyhalite which is packed with essential nutrients needed
for sustainable agriculture.
