Polyhalite is a new, organic fertilizer produced and sold under the brand name Polysulphate. Field trials have proven that it is an effective crop fertilizer. It is found over 1,200m below the Earth’s surface, under the North Sea along England’s north-eastern coast. Polyhalite comes from the polyhalite layer of rock, deposited 260 million years ago.
Polysulphate is a multi-nutrient fertilizer. It contains readily available sulphur plus potassium, magnesium and calcium which ensures increased crop yields and improved crop quality. In surveys showing that potash reserves are dropping globally, there’s never been a better time to mine t his exciting new fertilizer.
48% SO3 as sulphate
14% K2O as from sulphate of potash
6% MgO as from magnesium sulphate
17% CaO as from calcium sulphate
In a world where populations continue to grow and the food demand consistently increases, it’s important to farm as efficiently and sustainably as possible. This is where polyhalite, our new natural jewel, provides the answer. Polyhalite is available in its natural state. There are no chemical processes meaning it is a fully organic, sustainable fertilizer with a low environmental footprint.
Both a granular and powder product, this fertilizer has fantastic spreading characteristics and can be used alongside other fertilizers such as nitrogen, complementing their benefits. UK field trials have shown a 40% yield improvement with the application of Polysulphate. What’s more, Polysulphate helps to replace the potassium lost during harvest times, particularly with straw-like crops such as cereals, making it a complementary addition to routine fertilizer cycles.
