Directions for use

Osmoform NXT is developed for topdress applications in container nursery stock crops but can also be used for other purposes where a long-lasting effect of nitrogen and potassium is required. The nitrogen and potassium in the product is releasing over a period of approximately 8-10 weeks after application.

In case of top dressing it is important to spread the amount of fertilizer evenly over the surface of the growing media. In case of application over the plants it is recommended to remove the granules from the leaves.

Store under dry conditions. Partly used or damaged bags should be closed well.

Recommended rates




Normal feeding

Heavy feeding

Container Nursery Stock

1 g/l

2 g/l

3 g/l

Apply max. 5 - 6 grams on one spot. For bigger pots/containers, divide the product. Do not leave unused product in applicators.

Rates need adjustment for specific growing media compositions (bark), plant species and cultivation system. For complete feeding of longer crops, additional feeding with Osmocote Exact or water-soluble fertilizer is recommended.

Contact ICL Specialty Fertilizers for more detailed advice. Trial first on a small scale before rate, application or other changes in you cultural practices are implemented. Attention: As circumstances can differ and as the application of our products is beyond our control, ICL Specialty Fertilizers cannot be made responsible for any negative results.

Osmoform NXT is based on the new granulation technology SILK (silica based) which includes slow release nitrogen and potassium. The slow release K is embedded in a 3 dimensional matrix, which slowly dissolves during time.
Osmoform contains NPK, magnesium and a package of trace elements. The nitrogen composition is balanced to have quick plant reaction after application and a long lasting effect afterwards. Osmoform NXT contains 1.2 - 2.8 mm granules.
