Application / Intended Use
Seaweed extract is used as a biostimulant and a source of natural hydrocolloids. Agriculture applies it as a foliar spray or soil drench to improve stress tolerance and root development, typically at 1-3 litres per hectare; food processors use the alginate and carrageenan fractions as gelling and stabilising agents in dairy and meat products.
