Organic Materials Review Institute

At the Mother Earth News Fair, I always enjoy speaking with fellow farmers and gardeners about inputs, organic standards and sound practices in the field. At the OMRI booth, we always provide free OMRI Products Lists of approved input materials, to help you find the right fertilizer or livestock feed additive and keep your farm or garden truly organic .

The Organic Materials Review Institute

The Organic Materials Review Institute was formed by organic certifiers back in 1997 to focus exclusively on the products and materials used by farmers.
