Ascophyllum Nodosum Extract is a natural seaweed extract derived from Ascophyllum nodosum, a brown marine macroalga commonly known as Norwegian kelp or knotted wrack. It grows along the rocky coastlines of the North Atlantic, particularly in cold coastal waters.
Ascophyllum nodosum extract contains naturally occurring polysaccharides, minerals, trace elements, amino acids, and other bioactive compounds. It functions as a plant biostimulant, designed to promote crop growth, root development, and nutrient utilization, while enhancing tolerance to environmental stress.
Green Agri supplies bulk Ascophyllum nodosum extract powder. Through enzymatic modification, the product is enriched with alginic acid, oligosaccharides, and polyphenols—containing over 20% alginic acid. It offers excellent water solubility and is well-suited for applications in agriculture, plant nutrition, organic fertilizers, and biostimulant formulations.
