Polysulphate: Perfect for NPK Production

Every farmer wants to see a good yield. Whether they get that or not will depend, to a large extent, on whether they plan, source, and apply the right fertilizer formula for the crop. Incorporating Polysulphate into granulated fertilizer makes a good yield more likely.  

Nutrients Available when Needed

Responding to the right soil temperatures, air temperature and available light, root and shoot growth in crops make their demands on available nutrients. Any shortfall in available nutrients is detrimental to crop performance. NPK granular fertilizers are often the first choice to keep crops fed and incorporating Polysulphate into NPK blends helps achieve the perfect balance of all crop nutrients required.  

Versatile Fertilizers

The effectiveness of existing NPK fertilizers is much improved with the addition of S, K, Mg, and Ca found in Polysulphate. It is compatible with a wide variety of NPK fertilizers allowing tailoring to the needs of various crops, soil types and climatic conditions.  

Efficiency in Production and Application

As if the versatility was not enough, there are other gains to be made too. NPK fertilizers based on Polysulphate have lower production costs and energy requirements compared with traditional SOP or MOP-based products.  

Replacing Filler with Nutrients

As much as 20% of NPK fertilizer is filler which is added to ease the handling, application or placement of the fertilizer. Replacing that filler with Polysulphate adds valuable extra nutrients, providing better value.

Advantages for Operators

Polysulphate helps granulation and increases output. For operators there are advantages: due to Polysulphate’s high crystal strength there is less likelihood of dust during production and handling.  

Lower Carbon Footprint

Choosing Polysulphate for NPK blends is also good from a carbon footprint perspective. Polysulphate is a natural mineral fertilizer that is simply mined, crushed, and screened ready for use. Carbon footprint calculations reveal that Polysulphate produces just 0.0029 kg of CO₂ equivalent per kg of product, which is less than any similar fertilizer product. So, using Polysulphate in NPK blends incorporates additional nutrients using a product with a minimal contribution to the overall product carbon footprint.  

Contributing to Yield Increases

Protecting the yield potential of the crop is key. For many farmers the main fertilizer raw materials will continue to be ammonium nitrate, urea, superphosphates, MOP and SOP. Compatible with all these, Polysulphate is the new alternative for use in NPK Fertilizers. It provides timely, and available, essential S, K, Mg and Ca. Farmers respond well to the offer of a cost-effective, low carbon-footprint, and efficient nutrient boost. The crops respond positively too.
