Summerwinds "Natural & Organic Potting Soil" contains: aged and processed softwood bark & sawdust, sphagnum peat moss, steer manure, pumice, perlite, bat guano, feather meal, and kelp meal. Dolomite may be added as a pH adjuster.
Unlike the Earthbox Organic Potting Mix, the Summerwinds one is not OMRI listed. http://www.omri.org/complete_company.pdf
I would say yours is organic with a small "o" rather than Organic.
