2. Key Active Components
- Polysaccharides (alginates, laminarin, fucoidan)
- Natural plant growth hormones (auxins, cytokinins, gibberellins)
- Amino acids & peptides (≥ 5% w/w)
- Betaines & polyamines
- Mannitol (osmoprotectant)
- Vitamins (B-group, E, C)
- Chelating agents (natural polyphenols)
3. Benefits & Mode of Action
- Significantly stimulates root initiation and elongation, resulting in stronger root systems and markedly improved nutrient and water absorption efficiency.
- Enhances chlorophyll synthesis and photosynthetic activity, leading to increased carbohydrate production and greater overall plant vigor.
- Activates natural defense mechanisms, substantially improving plant tolerance to abiotic stresses including drought, high salinity, extreme temperatures, and UV radiation.
- Promotes earlier and more uniform flowering, higher fruit set percentage, reduced fruit drop, and better size uniformity, ultimately contributing to higher marketable yield and improved crop quality.
- Stimulates proliferation of beneficial soil microorganisms, enhances microbial diversity, and accelerates organic matter decomposition.
- Increases soil cation exchange capacity and water-holding capacity through alginic acid and polysaccharide content, thereby improving long-term soil structure and fertility when regularly applied.
4. Compatibility
Fully compatible with most water-soluble fertilizers, fungicides, and insecticides (except strong alkaline products pH > 11). Jar test recommended before large-scale mixing.
