About this product

Polysulphate Premium

Polysulphate Premium is a natural single-component fertilizer of large, smooth granules of polyhalite mined in the United Kingdom. Free of nitrogen and phosphorus, it supplies potassium (13% K2O), sulfur (45.6% SO3), calcium (16.4% CaO) and magnesium (5.6% MgO) in a water-soluble form with prolonged release. The uniform spherical granules mix easily with other granular fertilizers and spread evenly. It is applied as a base dressing for potatoes, vegetables, fruit, oilseed and other quality-demanding crops, feeding four elements in a single pass.

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.
