Abstract: A system and method for commercial production of aqueous Sargassum seaweed extract concentrate having arsenic level of around 1.32-15 mg/l; cadmium level of around 0.005-5 mg/l; lead level of around 0.2-12 mg/l; mercury level of around 0.00002-2 mg/l; and pH of around 7.4-9 is disclosed. The resulting seaweed extract concentrate can be used in plant and soil amendments, rooting hormones, other organic plant and soil amendments, organic fertilizers, adjuvants for use with organic pesticides, organic fungicides, in combinations of organic pesticides, with fungicides, and as fertilizers for agricultural, commercial and domestic use. The resulting seaweed extract concentrate can also be used to regulate plant growth, or as a plant nutrient. The method is believed to be able to prepare an extract concentrate from any high protein biomass, including Sargassum, water hyacinth or other seaweed.
