Slow release fertilizers

ICL Specialty Fertilizers’ 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.

Topdress FT 4-5M

22-5-6+2MgO+TE

Osmocote Topdress FT is a coated fertilizer that is specially developed for topdress applications in container nursery stock. It contains Fusion Technology: a special component that makes the product stick onto the growing medium after application. This means no granules are lost if the pots are blown over.

Osmoform 38N (High N) is a slow release fertilizer. The working principle is not based on a coating around the granules like with Osmocote, but on long nitrogen chains breaking down slowly. This process is influenced by temperature, microbiological activity and humidity.

Osmoform 38N (High N) contains purely nitrogen. The nitrogen composition is balanced to have quick plant reaction after application and a long lasting effect afterwards.
