SiLK Technology

SiLK is a slow-release potassium and silicon technology used in Sierraform GT fertilizers.

Potassium and silicon are held within a matrix that gradually breaks down in the presence of moisture, providing release over approximately 8 weeks.

How SiLK works

Moisture activates the release process, with potassium and silicon released progressively as the matrix breaks down from the outside in.

This provides a sustained nutrient supply rather than releasing all of the potassium immediately after application.

Benefits of SiLK

• Gradual potassium release over approximately 8 weeks.
• Extended potassium availability compared with immediately soluble potassium sources.
• Reduced risk of rapid potassium loss from the rootzone.
• Designed for fine turf, using the small SuperMicro granules found in Sierraform GT.
