materials and inputs

Where can I buy potting soil for organic gardening?

Potting soil, soil amendments, fertilizers, and pesticides/herbicides are not certified organic. These types of products are “approved for organic production” by agencies like the Organic Materials Review Institute or Washington State Department of Agriculture, who certify products to be allowed for use in organic production. Each product or material is scrutinized by an independent organization like OMRI to ensure that it meets standards for organic production and includes approved ingredients.

What non-organic ingredients/materials can I use in or on my organic processed product?

The National List is the definitive source for allowed materials. However, several agencies and organizations create comprehensive lists of brand name products and ingredients that may be used in organic processing. Among them are the Organic Materials Review Institute (OMRI) and the Washington State Department of Agriculture.

The CCOF certification staff told me they cannot advise me on materials. Is help available?

Yes! We maintain a list of organic consultants and organic agricultural advisors who are available to assist with certification and regulatory compliance issues. We understand that choosing materials appropriate for your specific situation can be challenging. Our staff is available to verify if a specific material is compliant; however, due to NOP regulations we are not allowed to make recommendations or provide specific types of products to use.
