SIL MARE NPK is a combined organic-mineral NPK liquid fertilizer with silicate and Ecklonia maxima seaweed extract. The formulation combines mineral nutrients with seaweed-derived compounds including phytohormones, polysaccharides and vitamins.
The product supplies silicon rapidly to plant tissues, where the source links it with stronger cell walls, more erect leaves, improved light interception, regulated transpiration and stronger physical resistance of plant tissues. It is designed for crop revitalization and strengthening during active growth and periods of environmental or biotic stress.

SIL MARE NPK combines NPK nutrition, silicon and Ecklonia maxima seaweed extract in one liquid formulation. The source states that seaweed-derived cellular components include phytohormones, especially auxins, together with polysaccharides and vitamins.
The technical document describes silicon accumulation in epidermal cell walls, leaves, stems and roots. It links this accumulation with stronger cell walls, improved light absorption, regulated transpiration, greater resistance to environmental stress and a stronger physical barrier in leaf cuticles.
Application Guidance: Use the crop-specific programmes below. The datasheet labels SIL MARE NPK for Soil/Foliar use, but the supplied application table does not provide a separate soil-specific rate. For mixtures with trace-element products, reduce the dose and perform a compatibility test before use.

SIL MARE NPK is intended for crop revitalization and strengthening where plants benefit from combined NPK nutrition, silicon and seaweed biostimulation. The source positions it for stronger tissues, environmental-stress support, natural self-defense mechanisms and improved crop production.
The source states that SIL MARE NPK has good compatibility with phytosanitary products. When mixing with trace-element products, reduce the dose and carry out a simple compatibility test with the intended components before use.
SIL MARE NPK is a liquid organic-mineral NPK fertilizer with silicon and Ecklonia maxima seaweed extract.
It contains 29% seaweed extract, 12.5% silicon as printed as SiO₃, 6.25% total nitrogen, 6.25% phosphorus as P₂O₅, 8.75% potassium as K₂O, 0.75% alginic acid and 0.25% mannitol.
The source identifies Ecklonia maxima as the seaweed source.
It is used for crop revitalization and strengthening, combining NPK nutrition, silicon and seaweed-derived biostimulant components.
The source states that silicon accumulates in epidermal tissues, strengthens cell walls, supports more erect leaves and improves the plant’s physical barrier.
Yes. The source links silicon with improved resistance to environmental stress such as heat and drought and states that it regulates transpiration.
Apply 3-4 L/ha at sprouting and repeat after fruit set.
The source prints 200-300 cc/cl in 1-2 applications during tillering and stem elongation.
The source prints 500 cc/cl, with crop-specific first-treatment timings and repeat intervals.
The source prints 400 cc/cl, applied after each cut.
The source states good compatibility with phytosanitary products. For mixtures with trace elements, reduce the dose and perform a compatibility test.
SIL MARE NPK is available in 1 L, 5 L, 10 L, 20 L and 1000 L formats.
