Original Sea Soil Amendment is a fully composted mix of fish byproducts and forest fines. It is an excellent soil amendment with which to integrate organic matter into your existing garden beds. We recommend spreading a thin layer of Sea Soil over the surface of your garden beds in the spring. This OMRI – listed product has an NPK ratio of 2.1-0.16-0.05. Original Sea Soil Amendment is made in BC. “Forest fines” is the term for waste produced from logging and milling – stumps, wood chips, and leaves. This material is milled and mixed with waste from the west coast fish packing industry, and composted for a minimum of two years. Original Sea Soil amendment is intended for use as a soil amendment, and should not be used as a soil substitute. We love using this product in the raised beds at our trial grounds.
