Sierraform GT CalMag is a fine turf fertilizer combining nitrogen and potassium with additional calcium, magnesium and trace elements.

MU₂ slow-release nitrogen provides sustained nutrition to support steady growth over 6–8 weeks, while SMX, ICL’s concentrated seaweed extract derived from Ascophyllum nodosum and based on Acadian Seaplants seaweed technology, supports root development and turf vigor.

The formulation uses homogeneous mini-granules for even distribution at relatively low application rates, making CalMag well suited to closely managed fine turf through the main growing season.

  • MU₂ slow-release nitrogen supports steady growth over 6–8 weeks
  • Calcium and magnesium provide additional secondary nutrition
  • SMX, based on Acadian Seaplants seaweed technology, supports root development and turf vigor
  • Magnesium contributes to turf color
  • Homogeneous mini-granules support even nutrient distribution
  • Suitable for low application rates on fine turf

Recommended Rate:
15 – 30 g/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
Apply to dry foliage and irrigate after 1 – 2 days if there is no rainfall.
2
Irrigation helps with dispersion and lowers risk of mower pick-up on close cut surfaces.
3
Watering-in after application will minimize footprint trails. Avoid applying during frosty or drought conditions.
4
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.
5
If spilled on pavement, concrete, clothes, etc. brush off immediately as it can stain. Contains iron: do not apply in case of risk of contact with concrete, marble, stone, fabric, or swimming pools.

  • 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.
