Here at Coast of Maine we are proud of the quality and consistency of our compost-based soils. Compost, we believe (naturally decomposed organic matter) is the key ingredient. Ours are made using carefully designed and tested recipes which include the very best ingredients (sustainably sourced from pristine ocean waters and local farms) combined with rigorous quality controls. We never use biosolids, municipal or household waste. Close attention to detail with frequent turning, sampling and testing plus a lengthy aging and curing process produces dark, rich compost.
