Ascophyllum nodosum

» Ascophyllum nodosum

With the development of science and analytical techniques, scientists being biochemists, plant agronomists, soil specialists or pest management developers have been working for the last 60 years on understanding the mechanisms and the benefits of seaweeds on the plants.

Several books have been written on the subjects to date (see A. nodosum pages) and hundreds of reports and scientific studies have been published.

In the late nineties and early 21st Century, a lot of attention has been given to the role of specific compounds of the brown seaweeds, the oligosaccharides (small carbohydrates).
