polysulphate-premium
Polysulphate Premium brings the advantages of robust, spherical, broad-spreading, easily-blended and natural fertilizer.
Polysulphate is a new fertilizer, high in sulphate, available in its natural state, and mined in the UK
A unique benefit is its additional natural content of other macronutrients. Polysulphate® fertilizer comes from the polyhalite layer of rock, over 1000m below the North Sea off the North Yorkshire coast in the UK. Deposited 260 million years ago, it lies 150-170m below the potash seam at the Cleveland Potash Boulby Mine.
The main polyhalite seam was reached in September 2010, bringing the first samples up to the surface. It is estimated there are one billion tonnes available from this one source.
Polysulphate (the trade name for this polyhalite fertilizer) is available as both a granular and powder product. The 2-4mm granular product has excellent spreading characteristics and is an ideal fertilizer to apply alongside straight nitrogen.
Polysulphate contains
- 48% SO3 as sulphate
- 14% K2O as sulphate of potash
- 6% MgO as magnesium sulphate
- 17% CaO as calcium sulphate
