ProTurf gives you a unique combination of mineral and controlled-release nutrition. Plus, you get the power of Polyhalite – a revolutionary 4-in-1 mineral containing potassium, calcium, magnesium, and sulphur in one granule. The unique Poly-S technology means the nitrogen is released over a period of two to three months to give you sustained growth. ProTurf puts state-of-the-art innovation to work for you.
What is Polyhaliste and why is it an important component of ProTurf Hi N fertiliser?
Polyhalite is a mineral containing four essential nutrients: potassium, magnesium, calcium and sulphur. As the name suggests, ‘poly’ (more than one) ‘halite’ (salt), is a complex crystal containing four minerals (S, Ca, Mg & P).Â
To grow and function well, turfgrass needs a balance of nitrogen and other key macronutrients.
- Potassium is essential for turfgrass health and stress tolerance.
- Calcium is needed for cell division and strong cell walls.
- Magnesium for photosynthesis and improved turf colour.
- Sulphur for protein synthesis.
This brings polyhalite into the picture. It provides all four essential macronutrients required by a grass plant alongside applications of nitrogen and phosphorus. When combined with controlled-release fertiliser technology, urea, a compound fertiliser, Polyhaliste results in healthy, even growth without surges. The turf responds quickly in all growing conditions, including hotter and cooler situations. The addition of magnesium significantly improves turf colour.
ProTurf’s controlled release technology allows for proper growth with no surges. The fertiliser’s uncoated portion ensures a quick response from the turf, even in cooler growing conditions. The typical response time after ProTurf Hi N has been applied is seven (7) days.
ProTurf Hi N Fertiliser is a balanced fertiliser that can be used all year and is suitable for all turf types.
