No, the compost does not have to be certified organic, but any compost you use must meet all the requirements of NOP section 205.203. The burden of proving that any compost used on a certified organic operation meets all the requirements of section 205.203 rests with the certified organic operation that uses the compost. That operation must show in its organic system plan, and be able to prove to its certifying agent, that the compost it uses meets NOP requirements.
