ICL’s slow release fertilizers deliver proven high-quality performance. Our slow release fertilizers are based on the principle of nitrogen chains breaking down gradually over time.
Nitrogen components break down slowly through temperature, water and microbe activity in the growing medium before they are available for plant uptake. And only after this has occurred are all the other nutritional components made available as nutrition. This creates a slow release of the fertilizer.
