Osmoform 8-10 weeks – Slow release fertilizer with SiLK technology

In nurseries, container cultivation, or garden centers, one of the most common problems is the same: plants that lose color, slow their growth, or show symptoms of chlorosis due to nutrient deficiency.

When this happens, a fertilizer that acts quickly is needed, but which also maintains nutrition for several weeks without constant reapplication.

ICL's Osmoform NXT 8-10 weeks is a professional slow-release fertilizer designed precisely to solve this problem. Thanks to its innovative SiLK silicon-based granule technology, it gradually releases nitrogen and potassium over approximately 8 to 10 weeks, providing constant nutrition that improves the vigor, color, and development of plants.

Its NPK 22-5-11 + 2MgO + micronutrients formula provides all the necessary elements to stimulate rapid growth, intense foliage greening, and increased plant resistance to stress.

For this reason, ICL's Osmoform NXT has become a widely used tool as a top dressing for container nursery plants, especially when the commercial appearance of the crop needs to be quickly restored.

Why choose Osmoform NXT for your crops?

This slow-release fertilizer for nurseries combines quick action with a prolonged effect that simplifies crop management.

Its main benefits include:

Rapid plant greening

Its high nitrogen and iron content stimulates a quick response from the crop, restoring intense green color in a few days.

Progressive nutrition for 8-10 weeks

The gradual release of nitrogen and potassium avoids fertilization spikes and keeps the plant nourished for several weeks.

Greater resistance thanks to silicon

SiLK silicon-based technology provides silicon to the crop, strengthening plant tissues and improving resistance to environmental stress.

Easy top dressing application

The fertilizer can be applied directly to the surface of the substrate in pots or containers.

Ideal for correcting nutritional deficiencies

Especially effective when plants show chlorosis or loss of vigor in the nursery or point of sale.

Compatible with professional fertilization programs

It can be used as a nutritional boost alongside controlled-release fertilizers such as Osmocote.

SiLK Technology: smart nutrition with a silica matrix

Osmoform NXT incorporates innovative SiLK granule technology, based on a three-dimensional silica matrix.

This system allows nutrients to be released progressively as the granule dissolves in the substrate.

This provides several important advantages in production:

• controlled release of nitrogen and potassium
• lower leaching risk
• more stable nutrition in the crop
• higher efficiency of the applied fertilizer

Additionally, the supply of silicon helps strengthen plant tissues, which improves the plant's resistance to environmental stress or mechanical damage.

Fertilizer composition

The NPK 22-5-11 fertilizer with magnesium and micronutrients offers complete nutrition:

• Nitrogen (22%) → stimulates vegetative growth
• Phosphorus (5%) → promotes root development
• Potassium (11%) → improves crop resistance and quality
• Magnesium (2%) → essential for photosynthesis
• Iron and micronutrients → prevent nutritional deficiencies
• Silicon → strengthens the plant structure

This combination makes it a silicon fertilizer for plant resistance especially useful in professional nurseries.

Recommended applications

Osmoform 8-10 weeks 20 kg bag is mainly used in:

• ornamental plant nurseries
• potted or container crops
• garden centers and points of sale
• recovery of plants with chlorosis
• crops in bark-based substrates where leaching is high

The usual dose for container nursery plants is:

• Low needs: 1 g per liter of substrate
• Medium needs: 2 g per liter
• High needs: 3 g per liter

For large pots, it is recommended to distribute the fertilizer evenly over the surface of the substrate.

Combine Osmoform with long-duration fertilization

Osmoform is ideal as a booster fertilizer or shock treatment in short or medium-cycle crops.

For crops that remain longer in the nursery, many professionals combine it with controlled-release fertilizers like Osmocote Exact, which provide nutrition for several months.

This system allows for a balanced fertilization strategy adapted to each phase of the crop.
