Sportsmaster CRF combines coated and uncoated nutrient sources to provide different stages of nutrient availability from the same application.
The uncoated nitrogen fraction provides the initial turf response, while the controlled-release component extends feeding for up to 3 months. The range is developed for turfgrass maintained above 12 mm and provides continued nutrient availability after the initial response.
This makes it suitable where both relatively rapid turf response and a longer feeding period are required from a granular fertilizer application.
Poly-S is a dual-coating controlled-release nitrogen technology available from ICL, combining sulfur and a biodegradable polymer. It ensures gradual nitrogen release over up to six months.

Sportsmaster CRF uses a blend of coated and uncoated nitrogen elements. The coated elements release nutrients gradually over time, while the uncoated elements provide an immediate nutrient boost. This ensures steady growth and minimizes nutrient leaching.
Benefits include consistent nutrient release, improved nutrient uptake, reduced risk of nutrient spillage into the environment, and a quick visual response within seven days. This helps maintain greener, healthier turf with regular, consistent growth.
Sportsmaster CRF offers a variety of formulations tailored for different needs, including Balanced, High N, High K, and Renovator. Each product is designed to meet specific turf management requirements and seasonal needs.
