🌱 Product Overview:
Kelp Extract Powder is a 100% water-soluble, plant-derived organic fertilizer made from fresh Ascophyllum nodosum, a nutrient-rich brown seaweed harvested from cold northern ocean waters. This premium extract is processed using low-temperature enzymatic hydrolysis and spray drying to preserve its natural compounds, making it ideal for enhancing plant vitality, soil fertility, and crop yield.
Rich in natural plant hormones like cytokinins, auxins, and gibberellins, as well as trace minerals, amino acids, alginic acid, mannitol, and vitamins, Kelp Extract Powder is widely used in organic farming, hydroponics, horticulture, and turf management.
