About this product
Polysulphate Premium is a natural single-component fertilizer of large, smooth granules of polyhalite mined in the United Kingdom.

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.
