Understanding Polysulphate solubility


Demonstrating Polysulphate fertilizer solubility with a rain simulator

In order to easily demonstrate Polysulphate fertilizer solubility we have used a rain simulator to illustrate the behavior of granular Polysulphate fertilizer.


Science of Polysulphate: a unique multi-nutrient fertilizer

Polysulphate contains 4 vital nutrients in one pure crystal to boost the growth of plants: Sulphur, Potassium, Magnesium and Calcium. ICL Fertilizers are the only producer of Polysulphate: the trade name for this unique polyhalite fertilizer.


Polysulphate: Conclusions from solubility experiments

We have extensively researched the science and solubility of Polysulphate. In this film we summarise the main findings from our experiments.


Understanding Polysulphate solubility: standard versus granular
In this film we compare the solubility of different grades of Polysulphate. Our fertilizer needs to be soluble so that the four mineral nutrients are available to the crop as it grows.


Understanding Polysulphate: solubility and release of nutrients
In this film the research teams examine the solubility of, and release of nutrients from Polysulphate, our unique, multi-nutrient and soluble fertilizer, and other sulphate fertilizers.


Understanding Polysulphate: rainfall and nutrient release
In minimal tillage systems our Polysulphate fertilizer is sprinkled on the soil surface. Farmers and their advisors need to know when the nutrients are released and over what time period.
