Turning Sargassum Seaweed into Soil

  Algae Europe December 2022

Sargassum seaweed plagues many beaches around the world although increasingly it is being seen as a resource to improve the soil.

In Fort Lauderdale, Florida, crews are out daily, scooping up the fresh sargassum from the beaches. They take truckloads of it to a park where the city repurposes it. By the time it decomposes it has very little smell, and it becomes fertile soil.

In this video the beach-threatening sargassum is being collected and mixed in with older seaweed and dirt. Then it sits on a pile and in about four months it goes from being a nuisance to a helpful and valuable resource.
