2. Key Active Components

  • High-molecular-weight polysaccharides (alginates, laminarin, fucoidan)
  • Natural plant growth regulators (auxins, cytokinins, gibberellins)
  • Free amino acids, oligopeptides and proteins
  • Osmoprotectants (mannitol, betaines, polyamines)
  • Vitamins (B-complex, vitamin C, vitamin E)
  • Phenolic compounds and natural chelators

3. Benefits & Mode of Action

This highly concentrated seaweed extract delivers powerful biostimulant effects:

  • Strongly promotes extensive root system development and increases fine root hair formation, dramatically improving nutrient and water uptake efficiency.
  • Enhances chlorophyll content and photosynthetic rate, resulting in greater biomass accumulation and improved plant energy status.
  • Significantly increases plant resilience to abiotic stresses such as drought, salinity, heat, cold, and UV radiation through activation of antioxidant systems and osmoprotectant accumulation.
  • Stimulates early and synchronized flowering, improves pollination and fruit set, reduces physiological fruit drop, and enhances fruit size, color, sugar content, and shelf life.
  • Boosts activity and population of beneficial soil microorganisms, accelerates organic matter mineralization, and improves soil aggregation.
  • Acts as a natural chelating agent, increasing availability and translocation of micronutrients within the plant and reducing fixation in soil.

4. Compatibility

Completely soluble and compatible with most fertilizers, agrochemicals, and biological products. Avoid mixing with highly alkaline materials (pH > 11) or calcium-based products in concentrated form. Jar test advised before tank mixing.

5. Storage & Shelf Life

  • Store in a cool, dry, well-ventilated area (5–35 °C)
  • Protect from direct sunlight and moisture
  • Shelf life: 48 months from date of manufacture when stored under recommended conditions
  • Reseal packaging immediately after use to prevent moisture absorption

6. Packaging

  • 500 g, 1 kg, 5 kg, 10 kg, 20 kg aluminum foil-lined kraft bags or aluminum pouches
  • 25 kg multi-wall paper bags with inner PE liner
  • 500 kg / 1000 kg big bags (optional)

7. Safety & Handling

  • Non-toxic, non-hazardous, fully biodegradable
  • Use dust mask and gloves when handling powder form
  • In case of eye contact, rinse thoroughly with water
  • Not for human or animal consumption
