FAQ

These are special mineral fertilizers with a high nutrient content, gradually releasing nutrients over a period of at least two years. This provides plants with long-term nutrition without the risk of over-fertilization.

• Long-term nutrient release
• Reduced risk of nutrient leaching
• Environmentally friendly
• Easy application in tablet or powder form
• Suitable for various plant and soil types

They are ideal for perennial plants such as fruit trees, shrubs, grapevines, forest and ornamental woody plants, as well as balcony flowers and perennials.

Tablets are placed into the soil close to the plant’s root system. The powder form is mixed into the substrate or applied directly to the soil surface.

They contain nitrogen in the form of urea-aldehyde condensates (ureaform), phosphorus, potassium, magnesium, and trace elements such as boron, copper, iron, manganese, molybdenum, and zinc.

Yes. Thanks to their slow nutrient release and chloride-free formulation, they are environmentally friendly and suitable for organic cultivation.

Under European climatic conditions, nutrients are released for at least two years, depending on soil temperature and moisture.

All three are slow-release fertilizers, but they differ in composition and specific applications. SILVAMIX® is universal, SILVAGEN® is optimized for forestry and ornamental woody plants, and SILVAFORM® is designed for specific applications depending on plant requirements.

Generally, combining them with other fertilizers is not necessary. However, in the case of specific plant requirements, nutrition can be supplemented according to expert recommendations.

They contain double potassium-magnesium phosphates, which have buffering capacity and positively influence soil pH, especially in acidic and strongly acidic soils.

Yes. Thanks to complex nutrition and stable micronutrient supply, they improve overall plant vitality and natural resistance.

No. Slow-release fertilizers operate on the principle of controlled nutrient release, so over-fertilization does not occur even during heavy rainfall or excessive irrigation.

For a standard fruit tree seedling, 4–6 tablets (approx. 40–60 g) are recommended, depending on soil conditions and planting hole size.

Yes. SILVAMIX® and SILVAGEN® products are often used in reclamation projects, revitalization of urban greenery, and plantings in parks and forests thanks to their long- lasting effectiveness.

Yes. Thanks to slow nutrient release and the absence of chlorides, they are environmentally friendly and suitable for organic cultivation.
