Made from polyhalite, it contains four of the six macro-nutrients and many micronutrients that are essential to plant growth. It allows farmers to maximise their crop yield, increase quality and improve soil structure with one simple product. Driving more sustainable farming Fertilisers replace the soil nutrients lost when a crop is harvested. But incorrect use of fertilisers can have negative effects on the soil and the wider environment, so more sustainable practices must be found. All plants use the same 17 essential elements to grow and survive. In order to obtain optimum growth and health, while preventing unintended environmental consequences, the right quantity of the right nutrients must be available at the right time and in the right place. POLY4 is perfectly suited to the need for this more effective, efficient and sustainable farming. It releases a broad range of nutrients to the soil at a time when the plant needs them most, while strengthening the soil structure. This means crops can maximise their nutrient uptake while soil erosion and leaching is minimised. Our polyhalite is simply crushed and granulated, without using chemicals, to produce a low carbon footprint fertiliser that is suitable for organic use. And because it improves plant disease resistance, it can reduce the likely need for pesticides. The best choice for farmers POLY4 provides premium crop performance at a lower cost and in a more environmentally friendly way than other similar fertiliser products. It is low in chloride and delivers multiple nutrients in one product, giving plants access to a broad range of nutrients throughout their growth cycle. This sustained nutrient delivery results in stronger, healthier crops and higher returns for farmers. Our high-quality product is available in granulated, powdered or chipped form to meet the needs of our customers, taking into account their crop needs, blending requirements, application method and soil conditions. It can be easily blended with other fertilisers to produce the optimal mix of nutrients for any crop. POLY4 advantages: Delivers greater nutrient uptake Bigger improvements in yield and quality Improves soil strength, structure and nutrient legacy Has an ultra low CO2 emission profile Is low-chloride and pH neutral Find out more at poly4.com Crop science Our global agronomy programme provides technical, agronomic and commercial validation for POLY4’s use as an effective multi-nutrient fertiliser suitable for widespread use in commercial farming. These studies test POLY4 on broad acre and high value crops directly against other potassium based fertilisers, both as a straight comparison and as a component in an NPK blend. Results consistently show that POLY4 outperforms other fertilisers in both crop yield and quality, demonstrating the agronomic advantage provided by POLY4's multi-nutrient content.

Pre-orders for POLY4 have already reached a peak aggregate volume of 13.8 million tonnes per year. Trends including a growing global middle-class population (and therefore increased consumption of agricultural products), increasing soil nutrient deficiencies (for example, of sulphur and magnesium) and diminishing arable land per person are increasing the need for large-scale production and use of multi-nutrient fertilisers. POLY4 is expected to attract demand in the global fertiliser market as a result of numerous advantages not typically found in standard fertilisers and, which taken together, make POLY4 distinctive, including its low chloride content (essential for chloride-sensitive high-value crops, like potatoes), low CO2 emissions and organic certification.
