Copy link The mineral polyhalite was formed more than 200 million years ago, and can be found over 1,200 metres below the Earth’s surface, in the bedrock under the North Sea along England’s north-eastern coast. This natural fertiliser is produced exclusively by the Boulby mine in North Yorkshire, England. The Boulby mine is the first and only Polyhalite mine, making ICL the sole producer in the world
Polyhalite is a natural mineral that is used as a fertiliser in turf management because of its unique composition of essential plant nutrients and its slow-release properties. Polyhalite contains four essential nutrients for plant growth: potassium (K), sulphur (S), magnesium (Mg), and calcium (Ca). These nutrients are all important for plant growth and development, and are typically found in different fertilisers. However, polyhalite provides them in a balanced and readily available form, making it a popular choice among turf managers.
One of the main benefits of using polyhalite in turf management is its slow-release properties. When applied to soil, polyhalite gradually breaks down over time, releasing nutrients slowly and steadily. This means that the nutrients are available to plants for a longer period of time, reducing the need for frequent reapplication and ensuring a sustained source of nutrients for healthy plant growth.

Another advantage of polyhalite is its ability to improve soil structure and health. The high sulphur content in polyhalite can help to lower soil pH, making nutrients more available to plants and improving soil structure. Additionally, the magnesium and calcium in polyhalite can help to improve soil texture and increase water-holding capacity, which can reduce the need for irrigation.
Polyhalite is also an environmentally sustainable option for turf management. Its slow-release properties mean that it reduces the risk of leaching and runoff, which can lead to water pollution and other environmental problems. Additionally, because polyhalite contains a balanced mix of nutrients, it reduces the need for multiple types of fertilisers, which can also help to reduce environmental impacts.
In summary, polyhalite is a popular choice for turf managers because of its balanced composition of essential plant nutrients, slow-release properties, ability to improve soil health, and environmental sustainability. By providing a steady source of nutrients to turfgrass, polyhalite can promote healthy growth and help to maintain a vibrant and sustainable turf surface.
