SilK – slow release potassium and silica matrix – is a technology developed by ICL and unique to SierraformGT that delivers potassium and Silica in a controlled way.
It reduces the loss of potassium through leaching and helps maintain a continuous supply of potassium and silica to the grass plant. Research has shown that as a result, turf is better able to tolerate wear stress, drought conditions and disease pressure.
The slow release potassium source in SierraformGT provides a gradual release of Potassium over time. This means that potassium losses are limited in terms of leaching and excessive uptake by the plant, which means that there is more available in the soil for the plant at a later date.
As the potassium is continuously released over time, it has the effect of spoon feeding the turf the correct level of K without the risk of over or under feeding or lock up within the soil.

Sierraform GT All Season contains NPK in a normal-release form plus slow-release nitrogen and potassium, a full range of trace elements to improve turf health, plus magnesium for a boost to colour. It's ideal for use after aerating to encourage growth.
Sierraform GT Anti-Stress helps your turf through stress and helps keeps it in peak condition. The high potassium content is perfect in the summer or autumn, in areas of fine turf. The slow-release nitrogen supports growth for 6 – 8 weeks and minimises growth surges.
The micro-granules contain standard-release and slow-release nitrogen and potassium, plus all essential trace elements. K-STEP's low nitrogen content means compact growth and hardened turf, while its magnesium will boost colour and hide the symptoms of stress. Ideal all year round, on all fine turf.
The single-compound micro-granules are easy to spread quickly and evenly, and feature our patented MU2 and SilK coatings. Momentum contains NPK in a classic turf-friendly 4:1:2 ratio, with nitrogen and potassium in both standard-release and slow-release form, to feed your grass for up to 6 – 8 weeks. Also formulated with magnesium for a boost to colour and trace elements for optimum health. Suitable for any area of fine turf and especially useful in the spring and summer when grass grows most actively.
Ideal for fine turf application through the summer and autumn, supplying calcium, magnesium and trace elements particularly where these are indicated as required from soil testing. The excellent granulation means that low application rates can be employed. The response is a sustained turf response from the MU based nitrogen. The added SMX seaweed in the formulation aims to bring benefits from plant rooting and stress tolerance.
A granular fertiliser to get your growing season off to a great start. Sierraform GT Spring Start has iron and manganese to boost photosynthesis and colour, and low levels of MU to help your turf start getting greener even in cooler conditions. The product also contains slow-release potassium, as well as standard-release nitrogen and potassium. Phosphate-free, so it helps you manage phosphorus build-up. Spring Start comes as homogeneous micro-granules, featuring our patented MU2 and SilK coating technologies.
