About ICL Sierraform GT Fertilisers

Nitrogen is the key nutrient for driving growth in a plant. Potassium ensures that your turf is even more resilient to external stresses. A sufficient quantity of Nitrogen and Potassium is released immediately after application, so that the plant can make use of it straight away.

After that, extra Potassium and Nitrogen is released over a period of several weeks, whenever the grass plant needs it. This keeps turf strong and healthy for several weeks after application. As a turf manager, you no longer have to worry - the Sierraform GT granules do the work for you.

  • Small, physical uniform granules for even spreading and quick dispersion.
  • Fast dispersion into the turf.
  • Chemically uniform, with every granule containing the same amount of NPK plus trace elements.
  • Dual effect thanks to the slow-release Nitrogen and slow-release Potassium.
  • Optimum protection against stress: cold, heat, drought and wear.
  • Perfect for a programmed approach.

Each small, uniform Sierraform GT granule (0.7-1.4mm) will contain the same analysis as on the bag. These tiny granules are also easy to spread and this ensures that the best coverage per square metre of turf is achieved. Every grass plant on your green therefore receives exactly the same quantity of nutrients. This results in even growth with a beautiful, uniform colour. Since the smaller Sierraform GT granules are absorbed into the soil so quickly, you can mow the grass again very soon after application, and the players will not experience any disruption to play.
