what's listed: kelp, humic, and fish. Anything else is "secret". I talked to a main head @ ABC organics about 5 months ago. Dude was insanely knowledgeable about horticulture, more into soil microbiology and nutrient availability. He was cautious about the info he gave about primordial solutions products. I believe it comes down to labeling issues. He did state that the products are derived from natural ingredients and no paclo or damino were ever used. Upon the end of our conversation, he explained his "mission statement" - all about the preservation of earth and how to restore soil fertility from land that was raped of. I've been using all of their products and have been very satisfied!
