Description
Polysulphate® is a new fertilizer, high in sulfate, available in its natural state, and mined in the UK. A unique benefit is its additional natural content of other macronutrients.
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.
Polysulphate 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.
Main uses
- For direct application in fields, orchards and plantations
- For bulk blending with other fertilizers
