Poly-S

 

Coated granule technology. Polymer and sulphur coating regulates nitrogen release to suit plant demand.

Nitrogen granules are coated first with sulphur (a plant nutrient in itself) and then a unique polymer membrane, which is degradable. Once moisture permeates this outer polymer membrane and sulphur coating, nitrogen is released.

Depending on the thickness of the coating, this release can last up to 6 months. Major increases in soil temperature and/or moisture do not create severe fluctuations in this release pattern, ensuring that Poly-S provides non-surge growth and a healthy, green turf even in warm, wet conditions.

Because nutrient uptake is so efficient, the risk of leaching is reduced.
