Seaweed is a versatile and resource-rich agricultural input offering solutions across multiple domains. It can serve as biostimulants, improving crop quality and stress tolerance, and as compost for enhancing soil health and productivity. In livestock fodder, it boosts animal health and productivity, with certain species like Asparagopsis significantly reducing methane emissions. Seaweed also has potential in aquaculture, serving as a cost-effective feed while improving water quality. The industry faces challenges with regulatory frameworks, limited local production, and ensuring scalability for economic viability.
