Dual effect thanks to slow-release nitrogen and slow-release potassium
The strong performance of Sierraform GT is unsurpassed with the dual effect of slow-release nitrogen and slow release potassium. Potassium ensures that your turf is even more resilient to external stresses... Nitrogen is the key nutrient for driving growth in a plant. If nitrogen can be delivered slowly to the plant then there are no flushes of growth after application and the growth of the plant will more even. This enables the plant to achieve a good balance of growth between leaf and roots. Potassium ensures that your turf is even more resilient to external stresses. A sufficient quantity of nitrogen and potassium is released immediately after application, so that the plant can make use of it straight away. After that, extra potassium and nitrogen is released over a period of several weeks, whenever the grass plant needs it. This keeps your turf strong and healthy for several weeks after application. As a turf manager, you no longer have to worry – the Sierraform GT granules do the work for you.




The slow release potassium is complexed within a 3- dimensional matrix. The outer links of the matrix are weakened in the presence of moisture, which enables the K contained within the outer cells to be activated and released in to the soil. K is released from the outside of each matrix and moves inwards over time as each layer is activated. Potassium is release overall period of approximately 8 weeks.
