About this product

Polysulphate Standard

Polysulphate Standard is a natural granular multi-component mineral fertiliser mined by ICL, which supplies potassium (13% K2O), calcium (16.5% CaO), magnesium (5.6% MgO) and sulphur (46.5% SO3 / 18.6% S) from a single product. It is well suited to direct application to the soil for cereals, oilseed rape, maize, potatoes, sugar beet, perennial grasses and vegetables; it efficiently meets the nutritional needs of plants and serves as a raw material for producing granular NPKS and PK fertilisers.

Questions & answers

What farmers ask most

  • Rates depend on crop, prior history, soil-analysis results, and current soil nutrient status. A typical NPK complex on cereals is 150–300 kg/ha. Use the /calculators/npk tool or consult an agronomist for an exact dose.
