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.
