Ascophyllum nodosum is a brown seaweed belonging to the order of Fucaceae, characterised by its long branches with apical vesicles, and growing on rocky substrates often at the dividing line of high and low tide. Ascophyllum nodosum is found in the Arctic basin, proliferating primarily along the North Atlantic coasts of Norway and Canada.
The extreme environmental conditions in which this special seaweed thrives means it is found completely submerged in the sea for some months of the year, and also spends time on the water for a long period of time exposed the sun and other climatic effects.
Thanks to these unusually hostile environmental conditions, Ascophyllum nodosum has evolved a singular ability to withstand stress, thanks to the presence of some valuable substances contained in it. Among these there are some containing powerful anti-stress properties that, if properly extracted, can be used for the production of specialty fertilisers able to confer some of the properties of Ascophyllum nodosum to the treated plants.
During 2002, Valagro integrated vertically through the acquisition of the Norwegian company Algea, the first company in the world to achieve, in 1942, a method of extraction of active ingredients from algae.
Thanks to this acquisition Valagro has become a global leader in the harvesting of Ascophyllum nodosum, particularly in the extraction of active ingredients.
