This unique high performing soil improver is produced using the brown seaweed Ascophyllum nodosum which is harvested by hand from the cold, clean, nutrient rich waters of the North Atlantic Ocean and, as such is an entirely renewable resource. It contains over 80 minerals, essential trace elements, vitamins and natural plant growth hormones including Cytokinins, which stimulate plant growth.
