When you’re overseeding or laying new turf, there’s no better solution than Sierraform® GT Preseeder. It contains both slow-release nitrogen and slow-release potassium, along with conventional release NPK (18-22-5) in a single compound micro-granule. The high phosphorus analysis in Preseeder promotes good rooting and establishment on your greens, tees, fairways, and sports fields, while minimizing salt levels to boost germination rates. Its nutrient release pattern is tailored to the needs of new turf or seed.

  • High P analysis to support seeding, overseeding and sod laying operations
  • Slow release N (MU) for consistent and sustained turf response
  • Even spread at low application rates

Recommended Rate:
15-30g/m2
Recommended Rate:

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
Use from March to September.
2
Apply to dry foliage and irrigate after 1 – 2 days if there is no rainfall. Irrigation helps with dispersion and lowers risk of mower pick-up on close cut surfaces. Avoid applying during frosty or drought conditions. 
3
Delay any vertical cutting and/or grooming until 3 days after application, to allow the granules to properly disperse. Significantly less nitrogen is released when soil temperatures are below 10° C.

  • MU₂ is ICL’s patented slow-release nitrogen technology designed to deliver consistent, long-lasting turf nutrition. It utilizes microfine granules composed of methylene urea chains that are broken down in the soil, releasing nitrogen over up to eight weeks. This ensures uniform growth, strong rooting, and minimal nutrient loss, even under variable environmental conditions.
