Polysulphate Premium is the latest addition to the Polysulphate family of products. It has the same benefits as Standard, Granular and mini-granular Polysulphate, with the added advantage of uniform, robust spheres with a smooth surface to protect from abrasion, humidity and damage. The smooth shape gives a consistent flow rate, and broad spread during application, and means that it can be easily blended with other fertilizer materials.

Polysulphate comes from the polyhalite layer of rock, over 3,300 ft below the North Sea off the North Yorkshire coast in the UK. Deposited 260 million years ago, it lies 490-560 ft below the potash seam at the Cleveland Potash Boulby Mine.

The main Polysulphate seam was reached in September 2010, bringing the first samples up to the surface. It is estimated there are one billion tons available from this one source.

Main uses
  • For direct application in fields, orchards and plantations
  • For bulk blending with other fertilizers

Polysulphate Premium brings the advantages of robust, spherical, broad-spreading, easily-blended and natural fertilizer.
