Research and field experience indicate that marine by-products can improve soil structure, enhance soil microbial activity, and promote plant growth. Current processing and distribution costs presently limit their use. Fish waste, fish emulsion, shellfish waste, and seaweed are the major classes of materials. Research has established that seaweed supplies some plant nutrients (especially micronutrients), enhances plant growth, and improves soil tilth.
