Gronamic Mini 6-2-4 is an organo-mineral fertilizer developed for fine turf, combining mineral nutrition with a 100% plant-based organic component.

Multiple nitrogen sources provide phased nutrient release for more even growth over 6–8 weeks. Polyhalite supplies potassium, calcium and magnesium, while recycled struvite provides slow-release phosphorus. The formulation also contains SMX seaweed extract, which has been shown in trials to increase root surface area in perennial ryegrass seedlings.

The 1–2.5 mm mini-granules are designed for even application and rapid dispersal on fine turf, making the product particularly suited to golf greens, surrounds, approaches, tees and other closely managed surfaces.

  • Multiple nitrogen sources provide phased release for more even growth
  • 100% plant-based organic component combines organic and mineral nutritio
  • Polyhalite supplies potassium, calcium and magnesium
  • Recycled struvite provides a slow-release source of phosphorus
  • SMX seaweed extract supports rooting
  • Fine 1–2.5 mm granules suit closely managed fine turf

Recommended rate 25 - 35 g/m2

Always trial on a small area before adjusting application rate or any other variables. As site conditions vary and application is outside ICL’s control, responsibility for results rests with the user.

1
Apply to dry foliage
2
Water in if no rain falls within 1-2 days after application. Irrigation or rainfall will assist dispersion and minimize risk of mower pick-up on close cut surfaces
3
Avoid applications during frosty or drought conditions
4
Delay cutting or grooming for 2 days after application to allow product dispersal

  • Polyhalite is a natural mineral used by ICL to supply potassium, magnesium, calcium, and sulfur in turf fertilizers. It provides a balanced, slow-release nutrient profile with minimal environmental impact, supporting strong turf health and sustainability.
