Seaweed Extract Flake / Powder
Ascophyllum Nodosum-Based Seaweed Extract for Specialty Fertilizer & Biostimulant Formulations
Product Overview
Seaweed Extract Flake / Powder is a marine-derived agricultural ingredient produced primarily from Ascophyllum nodosum, a brown seaweed widely used in specialty crop nutrition formulations.
The material is processed through low-temperature enzymatic hydrolysis and spray drying to obtain a concentrated, water-soluble seaweed extract suitable for fertilizer manufacturing.
Depending on the selected grade, it contains seaweed polysaccharides, alginic acid-related compounds, mannitol, naturally occurring organic substances, and trace elements derived from marine algae.
Available in flake and powder forms, Seaweed Extract is suitable for manufacturers developing water-soluble fertilizers, liquid crop nutrition products, foliar formulations, and seaweed-based biostimulant products.
TerraNutrix Agricultural Solutions LLC supports B2B sourcing of seaweed extract ingredients for fertilizer manufacturers, formulators, and agricultural distributors.
