Southern Tier NY | True. The Organic Food Production Act of 1990 stated clearly that land based production systems must use soil. OFPA was written based upon current regulations in place at the time, and almost all certifiers were in agreement. In much the same way you couldn't live on simply water and supplements / vitatmin pills, hydropnic systems cannot provide the full range of nutrition that soil does. | |
