SIL MARE NPK
Seaweed-Based NPK Fertilizer with Silicon for Stronger, More Resilient Crops
SIL MARE NPK is a liquid nutrient corrector for foliar and soil application. It contains natural seaweed extract derived from Ecklonia maxima, a seaweed source valued for its content in biologically active compounds such as auxins, polysaccharides, vitamins, alginic acid and mannitol. These components work together with nitrogen, phosphorus and potassium to promote crop vitality and physiological balance.
The product also supplies silicon in a readily available form. Silicon accumulates in plant tissues, especially in epidermal cell walls, leaves, stems and roots, helping to reinforce the plant structure. As a result, SIL MARE NPK supports more upright leaves, better light interception, stronger cell walls, improved resistance to heat and drought stress, and a stronger natural physical barrier against external aggressions.

Multi-Benefits
SIL MARE NPK offers a triple-action approach: nutrition, biostimulation and structural strengthening. The NPK fraction supports essential crop metabolism, the seaweed extract promotes physiological activity, and silicon helps reinforce tissues and improve the plant’s natural response to stress.
Applied preventively, it helps crops maintain stronger tissues, more efficient transpiration regulation and better tolerance to challenging growing conditions such as heat, drought or disease pressure. It also contributes to a healthier canopy architecture by promoting more erect leaves and improved light absorption.
Key Benefits
- Strengthens cell walls and plant tissues.
- Promotes more upright and better-structured leaves.
- Supports natural plant self-defense mechanisms.
- Helps improve resistance to heat and drought stress.
- Contributes to better water-use efficiency through transpiration regulation.
- Enhances light absorption capacity.
- Supports faster recovery and wound healing.
- Helps make plant tissues less attractive to chewing and sucking insects.
- Improves crop vigor, productivity and overall plant performance.
- Suitable for both foliar and soil application.
Technical Advantages
SIL MARE NPK combines the nutritional value of NPK with the physiological activity of Ecklonia maxima seaweed extract and the structural benefits of silicon. Its liquid formulation allows easy handling and integration into fertigation or foliar spray programs.
Silicon contributes to the formation of a natural physical barrier in the cuticle and cell walls, helping crops better withstand environmental stress and pathogen pressure. The presence of alginic acid and mannitol from seaweed extract improves the biostimulant profile of the product, supporting plant metabolism during key growth stages.

Recommended Crops and Timing of Application
SIL MARE NPK is recommended for a wide range of crops, including fruit trees, citrus, vines, cereals, corn, rice, garlic, onion, potato, watermelon and turf. It is especially useful during periods of active growth, early vegetative development, sprouting, tillering, post-transplant establishment, fruit set and recovery after cutting in turf.
The product is best positioned as a preventive strengthening solution before periods of stress, high pest or disease pressure, heat, drought or intense vegetative demand. In crops such as apple, citrus and vine, applications at sprouting and after fruit set help support canopy structure and fruit development. In vegetables and field crops, early applications help reinforce young tissues and promote stronger plant establishment.
