Polysulphate: Polyhalite Based Fertilizers

ICL NPKpluS is our new line of granular NPK (nitrogen, phosphorus, and potassium) fertilizers with Polysulphate inside. The application of an ICL NPKpluS formulation provides six essential nutrients in one single operation: nitrogen, phosphorus, and potassium along with sulfur, magnesium, and calcium. The composition of ICL NPKpluS with three soluble sulfates (magnesium, potassium, and calcium) guarantees complete and efficient fertilization for the most demanding crops. ICL NPKpluS offers farmers the perfect balance between the most efficient raw materials and the most advanced technology, improving crop yields compared to traditional fertilizer practices.

ICL PKpluS is our line of PK (phosphorus and potassium) granulated fertilizers based on Polysulphate, containing five nutrients. The application of an ICL PKpluS formulation allows farmers to apply phosphorus and potassium along with sulfur, magnesium, and calcium in a single operation. A considerable proportion of the potassium content is in sulfate (SO4) form (20–35%), allowing flexible use in many crops. ICL PKpluS is available in a variety of formulae grouped into three types: high phosphorus for best plant establishment balanced phosphorus and potassium for a balanced and efficient nutrient supply, and high potassium for extra crop quality. Tailor-made ICL PKpluS fertilizers with additional micronutrients are available by request.

ICL PotashpluS™ is a granular fertilizer made with Polysulphate and potassium chloride. It provides crops with vital potassium, sulfur, magnesium, and calcium in a single application. ICL PotashpluS provides 37% potassium oxide, consisting of 30% potassium chloride and 7% as potassium sulfate. The sulfur, magnesium, and calcium in PotashpluS are all in 100% sulfate (SO4) form. With ICL PotashpluS, there is no need to choose between chloride or sulfate forms of potassium fertilizer: 20% of the potassium is in sulfate form, which reduces the chloride input by 50% compared with KCl. ICL PotashpluS is now included in the FiBL list of permitted inputs for organic production in Germany and Spain.

Megapoly is a new granular fertilizer made with Polysulphate and potassium chloride. An effective potash fertilizer, Megapoly also provides crops with sulfur, magnesium, and calcium – all in a single application. It is a powerful combination of quick-release and prolonged-release nutrients to suit crop needs.

Treat your crops to the perfect all-round nutrient hit with ICL’s premium PLUS fertilizer range. Our PLUS fertilizers are based on Polysulphate formulations and include a wide variety of products to suit the individual nutritional needs of all crops and soil types. Unlike traditional nitrogen-rich fertilizers, these sulfur-based products enable you to reduce harmful ammonia emissions, groundwater pollution, and soil acidification. Containing Polysulphate, the world’s only natural 4-in-1 fertilizer and a product with an unusually low carbon footprint, the ICL PLUS fertilizers are exceptionally environmentally sustainable. These Polysulphate-based products provide a prolonged nutrient release, aligning with your plants’ nutritional needs in real-time throughout their growth. This sustained release reduces the risk of sulfate leaching and, combined with the natural nutrient mix, promotes root development to provide superior, high-quality yields. This gives you increased crop profitability and excellent value for money. Everything adds up with ICL PLUS.

Mined in the UK in its natural crystal state (polyhalite), Polysulphate contains four essential nutrients: sulfur (S), potassium (K), magnesium (Mg), and calcium (Ca), all in sulfate form. Polysulphate has a natural, unique dissolution pattern that releases nutrients gradually after application. This prolonged availability is a real plus for growers, as it reduces nutrient losses while also matching nutrient availability to the uptake requirements of crops. The net result, backed up by extensive crop trials, is that Polysulphate increases the nutrient use efficiency of crops, increasing their yield and crop quality. Polysulphate stands out as an eco-friendly choice for farmers. With its natural composition – it is simply mined, crushed, and screened – Polysulphate has an exceptionally low carbon footprint. In fact, Standard, Granular, and Mini Polysulphate have the lowest carbon footprint (compared to similar products) of just 0.0029 kilograms of CO2 equivalent per kilogram of product, clearly setting Polysulphate apart from other fertilizers. Polysulphate sets the standard in environmental sustainability among fertilizers. With certification agencies around the world, including Ecocert, Ceres, Control Union, and OMRI, approving Polysulphate for organic farming systems, growers for traditional and organic markets can benefit from the PLUS of using Polysulphate. Recently, Polysulphate fertilizers were certified to comply with UK’s OF&G Standards and also approved for use in organic systems. ICL Polysulphate: Always look for the PLUS.

Sofipoly is a new granular fertilizer made with Polysulphate and potassium sulfate. This effective potash fertilizer provides crops with vital potassium along with sulfur, magnesium, and calcium – all in a single application. Sofipoly is a powerful combination of quick-release and prolonged-release nutrients to suit crop needs. All the nutrients are in sulfate form, making Sofipoly the ideal potassium fertilizer for chloride-sensitive crops. It has a lower salinity index compared to alternative potassium fertilizers, which means there is less risk of soil salinization.
