Rapeseed Nutrient

SOLER R is a highly effective micronutrient fertilizer specifically designed for rapeseed cultivation. With its high concentration of sulphur and systemic copper, it effectively nourishes rapeseed and ensures better growth and yields. Its gel-like consistency allows the nutrient components to be almost entirely absorbed by the plants. The advanced SILEVEL™ technology enables slow and long-lasting release of nutrients to the plants, ensuring proper nourishment, while the high content of sulphur and systemic copper enhances crop health. Additionally, the rapeseed fertilizer is supported by the stimulating mechanism QM6™, which prompts rapeseed crops to engage in defensive mechanisms during adverse vegetative stages.
Available packaging:
1 L
5 L
20 L

Benefits of use:

Addresses micronutrient deficiencies in rapeseed
Gel-like consistency is almost entirely absorbed by plants
High sulphur and systemic copper content ensures proper nourishment and influences crop health
Stimulates rapeseed for growth and yields
Easy to dose and prepare solution

Product description:


The product contains boron, molybdenum, copper, manganese, zinc, and sulphur. Proper doses of mineral components tailored to rapeseed needs positively affect plant life processes, nutrient absorption, and ultimate crop yield. The strength of SOLER R rapeseed nutrient solution lies in its high dose of systemic copper and sulphur. These components interact with plants in a highly efficient manner – not only strengthening and stimulating growth but also acting disinfectant and health-promoting. Highly absorbable copper and sulphur support plant resistance to fungal diseases.

The advanced SILEVEL™ technology of the silicon-based hydrogel SOLER R enables the encapsulation of nutrient components in a kind of "pockets" – interpacket spaces from which these components are slowly and durably released to plants. The "packaging" technology of mineral components reduces field trips and associated costs of rapeseed cultivation, while increasing the profitability of sowings. SOLER R rapeseed nutrient solution releases minerals for a very long time and in an extremely efficient manner, ensuring that the availability of macronutrients is spread throughout the plant's life cycle, providing them with nourishment at every stage of development, especially during critical moments like budding, flowering, and seed maturation.

SOLER R is hygroscopic, easily swelling in water and resistant to drying out, while maintaining excellent adhesion to plants and being resistant to washing away by rain. The fertilizer, enriched with the stimulating mechanism QM6™, stimulates plants to engage in defensive mechanisms and increases their ability to accumulate water and nutrients supplied by the fertilizer. Thanks to the QM6™ technology, mineral components are available to plants immediately after the application of the fertilizer and can support crop health at critical moments. The result of using the innovative SOLER R rapeseed nutrient solution is a significant improvement in yield quality.

SOLER R rapeseed fertilizer is a safe, chlorine-free product with disinfectant properties. The nutrient solution also has fungistatic properties – it counteracts the development of fungi and other pathogenic disease agents. SOLER R is a product dedicated to professional users, but it will also be successful in small farms focusing on natural cultivation methods.

Boron (B) – 1.00% (w/w), Copper (Cu) – 1.50% (w/w), Manganese (Mn) – 4.00% (w/w), Molybdenum (Mo) – 0.02% (w/w), Zinc (Zn) – 3.50% (w/w), Sulphur (SO3) – 12.30% (w/w).

Additional information:

SOLER R fertilizer dissolves well in water and is easy to pour, while its gel-like consistency allows for convenient dosing. The rapeseed nutrient solution is resistant to long-term storage, and even after many months, it retains all its user values.

SOLER R, as the only product of its kind on the market, does not contain nitrogen and other inert elements, and all its components dissolve completely in water.
