Seaweed Fertilizer: The Science of Biostimulants
FAQ
Q: Can seaweed fertilizer replace chemical fertilizer?
No. Seaweed is a biostimulant that regulates physiology, stress resistance and quality, but it does not supply enough macronutrients for yield. It complements, not replaces, base fertilizer.
Q: What are the active components?
Alginates, mannitol, betaines, auxin-like compounds and trace minerals. They improve root growth, nutrient uptake efficiency and abiotic-stress tolerance.
Key Points
Seaweed = biostimulant, not a macro source
Active: alginates, betaines, plant hormones-like
Benefits: roots, uptake, stress, quality
Position: functional add-on to base fertilizer
