  • A natural zeolite called Clinoptilolite

  • An ivory coloured free-flowing granular product.

  • Approximate formula: (Ca, Fe, K, Mg, Na) 3-6Si30Al6O72.24H2O

Product Usage

Apply Zeolite either by top dressing or “drill and fill” techniques. Improves nutrient and fertiliser retention in the root zone Granules absorb soluble nitrogen and potassium, reducing leaching of key nutrients Porous granules increase aeration resulting in healthier turf Improves germination rates Helps protect against fertiliser scorch Robust granules resist soil compaction
