Agreed and I apologize if I misunderstood what you said. I thought the point you were trying to make was that by providing suitable conditions, the biology would follow naturally. All compost is not created equal, I think we all can agree on that. If your local sources of compost are somewhat questionable with respect to the biology, then perhaps finishing the composting process yourself may be a viable answer. My intent with suggesting local sources of compost is that it is more sustainable approach than manufacturing a product and shipping it to the site.
