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.
