Polysulphate

Polysulphate Granular fertilizer provides sulfur, potassium, magnesium, and calcium—four essential macro-nutrients required for optimal plant growth.

Highly soluble and easy to blend and apply, Polysulphate is a smart and cost-effective alternative to gypsum. A naturally occurring sulfate-based multi-nutrient, it provides a season-long source of plant-available nutrients. Low chloride and salt indexes, along with neutral pH, make it a safe choice for sensitive crops.

Benefits

Naturally low salinity levels and extended nutrient delivery reduce the risk of crop injury

pH neutral— Like gypsum, Polysulphate provides essential nutrients without affecting the growing media pH

Superior to gypsum for water supplies high in sodium and calcium, but low in magnesium

Plant-available nutrients in sulphate form

Compatible with most other fertilizers and can be incorporated in pre-mix potting soil

No special equipment needed

Low carbon footprint
