Sierrablen uses controlled-release fertilizer technology to provide long-term nutrient availability across larger managed turf areas.
Depending on the formulation, a single application can provide feeding for up to 9 months. The range is suitable for areas including golf tees and fairways, outfields and sports turf where a longer feeding period can reduce the frequency of fertilizer applications.
Controlled nutrient release provides an alternative to shorter-duration feeding programs where maintaining nutrient availability over an extended period is the main requirement.

Sierrablen is a premium range of controlled-release fertilizers designed to provide consistent, reliable, and long-lasting nutrition for turf. It leverages ICL’s unique controlled release technologies to ensure peak performance in every season and weather.
Sierrablen uses advanced coating technologies to gradually release nutrients over an extended period. This ensures a steady supply of essential nutrients to the turf, reducing the risk of nutrient leaching and excessive growth flushes.
Benefits include up to nine months of precision nutrition from a single application, consistent nutrient release patterns, and effectiveness in all weather conditions. This helps save time and money while maintaining healthy and strong turf.
Sierrablen offers a variety of formulations tailored for different needs. Each product is designed to meet specific turf management requirements.
Sierrablen fertilizers are best suited for turf areas mown at heights above 12mm, such as fairways, tees, outfields, and general landscaping. They’re not recommended for fine turf or areas cut below this height.
