Israel Agriculture 2017 Introduction Polysulphate is a new multi-nutrient fertilizer, available in its natural state, and mined in the UK. It has four nutrients, which makes it a unique product: sulphur, magnesium, potassium and calcium. It is a soluble material therefore its nutrients are readily available for plant uptake. Polysulphate comes from the polyhalite layer of rock, over 1000m below the North Sea off the North Yorkshire coast in the UK. Deposited 260 million years ago, it lies 150-170 m below the potash seam at the Cleveland Potash Boulby Mine. The main Polysulphate seam was reached in September 2010, bringing the first samples up to the surface. Polysulphate is a naturally occurring mineral fertilizer and is available as both a granular and powder product. It can be applied in many forms to the soil according to the consumer demand (straight fertilizer, or can be used in blends or for use in compound fertilizer manufacturing). The 2-4mm granular product has excellent spreading characteristics and is an ideal fertilizer to apply alongside straight nitrogen. It is suitable for all crops and being a low chloride fertilizer, it can be applied to even the sensitive ones. Polysulphate is available in its natural state and has a low carbon footprint. It delivers dependable high value for low environmental impact and is certified for organic use in different countries, like UK, France, Germany, Italy, USA and Canada. Polysulphate contains: 48% SO 3 (19.2% S) as sulphate 14% K 2 O (11.6% K) as sulphate of potassium 6% MgO (3.6% Mg) as magnesium sulphate 17% CaO (12.2% Ca) as calcium sulphate Polysulphate is an ideal natural source for all crops, especially brassicas, cereals, pulses, field vegetables, clover- rich grassland leys and silage crops. It is particularly suitable for crops which prefer low levels of chloride in the soil, such as tobacco, grapes and other fruits, and where higher dry- matters are desired in potatoes. It is a versatile product; suitable or all kind of crops and all types of soils. It has a 16 I ntroducing Polysulphate ™ , a Multi Nutrient New Fertilizer

neutral pH and very low salinity index. Polysulphate has a good and uniform spreadability in the field, up to 36 m (120 ft).Currently, hundreds of experiments are being carried out around the world, for different crops and soils. These trials have been repeated many times over the last ten years, both in pots and in the field. In every case Polysulphate has performed equally well or better than the best standard alternatives. The results confirm Polysulphate’s effectiveness as a multi-nutrient fertilizer. Our latest experiments point to the special solubility nature of Polysulphate that provides a prolonged release of sulphur; thus reducing the risk of leaching in sandy soils and under high precipitation.
Polysulphate productionPolysulphate is the trade mark of the mineral ‘Polyhalite’, which is one of a number of evaporate minerals containing potassium. The content of impurities is low, and is almost entirely sodium chloride at a maximum inclusion of 5%. Polyhalite (dehydrate) is a single crystal complex with 2 molecules of water of crystallization. It is not a mixture of salts. The chemical formula is: K2Ca2Mg(SO4)4•2(H2O)A seam of high grade polyhalite was found in the United
Kingdom, below the existing sylvinite seam which is being mined for the production of KCl (potassium chloride or muriate of potash) by Cleveland Potash Ltd. Twin shafts were sunk into the polyhalite seam from the potash level in the existing mine and the mineral is being extracted. This is the first operational polyhalite mine in the world.Unlike blended or compound fertilizer, Polysulphate is available in its natural state. It is mined, crushed, screened and bagged, involving no chemical separation or other industrial processes.Available in its natural form, Polysulphate is UK-sourced and has a low carbon footprint. It delivers dependable high value, for low environmental impact. The natural process by which Polysulphate is produced makes it a low carbon footprint fertilizer. This helps growers achieve carbon targets demanded by retailers and some food processors.
