"I have worked with organic agriculture since 1981 at the Rodale Research Center. Organic soil management is a complex issue and involves complexity in the soil. Hydroponics does not even come close to organic soil management. It is a chemical based approach that has no place in organic agriculture. All the soil interactions that make organic organic are missing. It is even more chemical intensive than conventional industrial agriculture. If that idea is accepted as organic then organic certification is almost a worthless concept. It bankrupts the idea and the science behind what organic agriculture is."
