The world of seaplants is a group of interrelated communities... each has a different focus. At one extreme we have communities with a completely financial interest. At the other extreme there are communities with a purely intellectual or aesthetic interest. Communities tend to revolve around discipline, environmental influences and uses. Most people belong to more than one community of interest (e.g. one discipline, at least one usage area and environmental impacts). Click on the hotlinks below to gain access to community links.

Agriculture and Industry Apps
The use of marine plants in terrestrial agriculture probably goes back as far as the history of agriculture among coastal people. As far as we know raw seaweeds and seaweed products (e.g. liquid hydrolysates, products of composting, ash from burnt seaweeds) have been used for millennia (and are still used today) as animal feeds, supplements to animal feeds, soil conditioners, mineral sources and fertilizers or plant foods.

One very large use of seaplants in agriculture is the use of coralline algae (marl) such as Phymatolithon calcareum and Lithothamnion corallioides as soil conditioners, trace element and mineral sources. They can also replace bone meal in some feed applications and ground marl is useful for water filtration. These algae contain calcium and magnesium carbonates that comprise up to 80% of the wet weight. Marl is dredged off the coasts of France (Brittany), England, and Ireland. Over 600,000 tons are harvested each year from live and dead deposits. The dried, ground product is favoured by organic farmers and horticulturists.
