Sierraform GT combines conventional and slow-release nutrient sources within a micro-granule fertilizer developed for intensively managed turf.
The conventional fraction provides readily available nutrition following application, while the slow-release component extends nutrient availability beyond the initial response.
The micro-granule formulation supports distribution across closely managed surfaces and is suitable for areas including greens, tees, fairways and sports turf. Combining the two nutrient-release patterns allows a single application to provide both readily available nutrition and continued feeding

SiLK is a slow-release potassium and silicon technology used in Sierraform GT fertilizers, providing gradual nutrient release over approximately 8 weeks.
Learn moreSierraform GT is a high-performance, long-lasting micro-granular fertilizer designed for fine turf. It combines conventional and slow-release technology to provide sustained nutrition and top performance.
Sierraform GT uses advanced slow-release technologies MU2 and SiLK to gradually release nutrients over 6 to 8 weeks. This ensures a steady supply of essential nutrients to the turf, reducing the risk of nutrient leaching and excessive growth flushes.
Benefits include consistent nutrient release patterns, rapid granule dispersion, and effectiveness in all weather conditions. This helps maintain healthy and strong turf with steady color and growth.
Sierraform GT offers a variety of formulations tailored for different needs, including Spring Start, All Season, Anti-Stress, CalMag, K-Step, Momentum, and NK. Each product is designed to meet specific turf management requirements.
Sierraform GT fertilizers are ideal for intensely managed turf that is cut lower than 6mm, such as greens and tees.
