EM-1 Microbial Inoculant has been OMRI Listed every year since 1994.

For operations that are certified organic, you'll save some time by having current copies of the OMRI Listing Certificates at time of inspection. Prepare 2 binders with all the documents your inspector will need. Keep one for yourself and give your inspector the other one. This will save you time and money. You can always get copies from OMRI.org and see the current list of allowed substances on their website. New certificates are issued some time toward the end of every calendar year.

EM-1® Microbial Inoculant, Ag1000® Organic, and EM-1® Waste Treatment are OMRI Listed without restrictions. "Allowed A". The OMRI Listing complies with the USDA National Organic Program for Certified Organic Producers.

Current OMRI Certificates are available on the OMRI website:
