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 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: 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.
