Biostimulants
Alginate Oligosaccharides
Premium Marine Oligomer Derived from Irish Atlantic Ascophyllum Nodosum
Our premium Alginate Oligosaccharide (AOS) is an ultra-pure, high-activity marine biostimulant derived from natural brown seaweed via advanced enzymatic hydrolysis. It features a strictly controlled degree of polymerization (DP 2-10) and an ultra-low molecular weight. This pristine, fully water-soluble powder acts as a powerful elicitor and signaling molecule, instantly penetrating plant tissues to stimulate root growth, boost crop defense, and dramatically enhance resilience against drought, salinity, and extreme temperatures.

Key benefits
- Elite Cellular Signaling & Stress Resilience Acts as a potent elicitor that rapidly triggers the expression of stress-resistance genes, enabling crops to survive and recover quickly from drought, frost, and salinity.
- Explosive Root & Lateral Root Development Stimulates the synthesis of endogenous auxins, promoting explosive root elongation and lateral root branching for maximized nutrient uptake.
- Fruit Quality & Coloring Booster Enhances sugar accumulation, accelerates chlorophyll synthesis, and promotes uniform fruit coloring and sizing in high-value orchard and greenhouse crops.
- Excellent Cold-Water Stability & Viscosity Reduction Unlike raw seaweed kelp meal which increases liquid viscosity and risks clumping in winter, AOS consists of short-chain oligosaccharides. It maintains low viscosity, provides flawless solubility, and lowers the crystallization point of liquid formulas. The finished product stays premium and fluid, even in colder climates.
- Synergistic Deflocculation & Nutrient Carrier AOS possesses highly dense active carboxyl groups that act as efficient, natural chelating sites. It easily forms compatible bonds with micronutrients ($Zn^{2+}$, $Fe^{2+}$, etc.) and macro-elements in the blending tank. This prevents nutrient chemical fixation and acts as a biological carrier for near-instant crop uptake.
Suggested dosage & application
- Foliar Spray Apply at 30 – 60 g active ingredient per hectare (g a.i./ha) during critical growth stages (budding, flowering, fruit expansion) or 2-3 days before anticipated climate stress.
- Fertigation / Drip Irrigation Apply at 60 – 120 g a.i./ha to optimize the root-zone ecosystem, stimulate root vitality, and enhance soil phosphorus mobility.
- As a Liquid Formula Additive Add 0.5% – 2.0% (w/w) into liquid fertilizers, seaweed extracts, or amino acid solutions. Benefits: AOS is a powerful elicitor (signal molecule). Adding it at just 0.5% – 2.0% transforms a standard fertilizer into a high-end Anti-Stress Product. It drastically triggers the plant's expression of stress-resistant genes, protecting crops against severe drought, cold shocks, and saline soils.
