ICL specializes in providing products and solutions for turf management, including fertilisers that are formulated to deliver the optimum level of nutrient to support healthy turf. These fertilisers come in different technologies, including:
Conventional fertilisers contain soluble nutrients that are quickly released into the soil when applied, providing immediate nutrition to the turfgrass.
Controlled-release fertilisers, on the other hand, have a coating that controls the release of nutrients, ensuring a steady supply of nutrition over an extended period. This technology helps to reduce the risk of nutrient leaching and waste, providing more efficient use of fertilisers.
Slow-release fertilisers are designed to provide nutrition over an extended period, slowly breaking down in the soil and releasing nutrients as the turfgrass needs them. This technology helps to maintain a consistent supply of nutrients to the turfgrass, promoting healthier growth and reducing the risk of nutrient deficiencies.
Extensive independent trial work has repeatedly confirmed the benefits of using premium formulations of fertilisers, such as those offered by ICL. By delivering nutrients in the correct form with an appropriate release pattern, these fertilisers can improve the sward quality, increase root mass, and radically reduce the level of disease activity. This means that by using ICL fertilisers, turf managers can achieve healthier, more resilient turf that is better able to withstand environmental stresses and disease pressures.
Overall, ICL fertilisers provide turf managers with a range of options to design effective and efficient nutrition programs to support healthy and high-quality turf. By choosing the right fertiliser technology and formulation, turf managers can ensure that their turfgrass receives the right balance of nutrients, promoting healthy growth and reducing the risk of nutrient deficiencies and diseases.

High impact granular fertiliser range for tees, surrounds, fairways, sports fields and lawns
ProTurf contains a combination of Poly-S controlled release fertiliser technology, readily available urea nitrogen and polyhalite, a unique multi-nutrient compound fertiliser. The controlled release Poly-S technology leads to consistent, regular growth over a 2-3 month period without growth peaks. The uncoated nitrogen allows an immediate response of the turf, even in cooler conditions. The multi-nutrient compound fertilser component contains four macro-nutrients (K, MgO, CaO & S) all in one granule.

Premium quality controlled release fertilisers for use on outfields, racecourses and greens surrounds
The coating technology provides nutrient delivery from 4-5 months to 8-9 months to suit individual requirements. The blends are free flowing and provide good even spread characteristics making them ideal for turf mown higher than 12mm. The Sierrablen analyses and release patterns are designed to optimise turf nutrition throughout the year and in a wide range of situations. The coatings are durable and they minimise the risk of any scorch or leaching problems.

Controlled release, granular formulation
Different nutrient inputs or release characteristics can be achieved depending on your requirements including quick response or slower, steadier release patterns based on the analysis selected. The mineral polyhalite is a component part of the Sierrablen Mini range. Polyhalite is a naturally occurring mineral fertiliser containing potassium, magnesium and calcium. We have found that the addition of polyhalite into our fertilisers results in improved turf colour, turf quality, turf vigour and growth rates. Sierrablen Mini fertilisers contain over 60%+ controlled release N in the form of our Poly-S technology. The Poly-S in Sierrablen Mini is a controlled-release nitrogen source that delivers nitrogen gradually and consistently over a 4 – 5 month period. The nutrient release is primed by moisture permeating through the outer polymer channels, through micro-channels in the sulphur layer and into the nutrient core where the urea is solubilised. Once the urea is solubilised it is released and made available for plant uptake. This means that the fertiliser is released at an optimum rate for plant uptake and the risk of leaching losses is minimised.
