Mark Highland
It was on a beautiful piece of Illinois farmland that Mark pushed his first shovel into garden soil. After he "grew up," he received an MS degree from the Longwood Graduate Program, focusing his research on compost and potting soils. After Longwood, Mark started The Organic Mechanic Soil Company, LLC in 2006. He has served as a consultant for the EPA and Institute for Local Self-Reliance, and he is the author of the recently published Practical Organic Gardening: The No-Nonsense Guide to Growing Naturally.
