Kelik K-Si

Engineering approach to plant nutrition

Kelik Potassium-Silicon by the Spanish manufacturer Atlantica Agricola is a specialized agent designed to correct the physiological state of crops under stress. The primary technical value lies in the synergy between potassium (K2O 10-20%) and silicon (SiO2), which acts as a structural building block for cell walls.

Why the K+Si combination is effective

In practice, the application of silicon combined with potassium solves two critical issues: physical tissue reinforcement and turgor regulation. Silicon deposits in the epidermis of leaves and stems, forming a rigid structure. This creates a mechanical barrier that impedes the penetration of pathogens (fungal spores) and reduces transpiration intensity—a crucial factor during extreme heat and drought conditions.

• Increased stress resistance: Silicon mitigates the negative effects of soil salinity and extreme temperatures.
• Cell wall integrity: The mechanical shield prevents fruit cracking and significantly improves post-harvest shelf life.
• Osmotic pressure regulation: Potassium facilitates the transport of assimilates and maintains water balance, which is vital for high-intensity crops like vegetables, fruit trees, and strawberries.

Technical Application

Formulated as a high-concentration aqueous solution, this product ensures excellent stability when used in tank mixes. Foliar application via spraying allows for rapid absorption through the leaf surface. The product is highly recommended for rapidly growing crops (such as cucumbers, cabbage, and carrots) where silicon deficiency can lead to lodging or reduced fruit quality. Using Kelik Potassium-Silicon is an investment in plant architecture, making crops resilient to both abiotic and biotic environmental stressors.
