Product Name: Seaweed Extract Liquid Fertilizer 12%
1. General Information
- Product Type: Natural marine biostimulant & organic fertilizer
- Raw Material: Freshly harvested wild Ascophyllum nodosum (North Atlantic knotted wrack)
- Extraction Method: Low-temperature alkaline hydrolysis + cell-burst technology (no chemical solvents)
- Active Substance: Total seaweed solids ≥ 12% (w/v)
- Form: Dark brown to black viscous liquid
- Odor: Characteristic marine seaweed aroma
2. Product Description
High-potency liquid seaweed extract derived exclusively from Ascophyllum nodosum collected from clean North Atlantic waters. The proprietary low-temperature extraction process preserves maximum levels of natural plant growth regulators (cytokinins, auxins, gibberellins), betaines, mannitol, alginic acid, and polysaccharides. This product acts as a powerful biostimulant that enhances root development, improves nutrient efficiency, increases tolerance to abiotic stress, and significantly boosts crop quality and yield. Suitable for organic farming and all conventional production systems.
