This label appears on foods and fibers that have been grown on certified-organic land, using organic inputs and processing facilities.
OMRI is the leading input reviewer in the United States, with 2,300 products and growing. This success can be attributed in part to high-quality, consistent professional reviews. With required testing for heavy metals, and lab results to support nutrient claims, OMRI always takes the most conservative stance in product decisions. OMRI's annual renewals and product change notifications also reduce fraud by verifying that each product formula remains compliant.
When an organic farmer wants to use a new product, his or her certifier can either review the product or accept the decision of an organization such as OMRI. Since products are always changing, certifiers who conduct their own reviews must often collect new information each time a grower wants to use it. This adds significant time and cost for both the certifier and the grower. It's easy to understand why OMRI Listed products are the preferred option for many farmers, processors, and certifiers.
The choice is more complicated for home gardeners. Certifiers don't inspect our yards for organic compliance, and it's easy to be confused and misled by product labels. Claims such as "organic" and "natural" on gardening products are, for the most part, not regulated. When a fertilizer package includes these words, it can simply mean that it contains carbon-based matter or some natural ingredients. It does not necessarily show that the product is free from toxic and persistent chemicals or that it is appropriate for an organic garden.
Whether you're a home gardener choosing organic, or a professional organic producer, remember that verified products for organic use will usually carry some sort of seal to support label claims. Be wary of misleading labels, and if you want to be sure a product is appropriate for organics, look for the OMRI seal. Before heading to the garden store, search the products and generic materials lists at omri.org, or download the products list, to help you find the right inputs for your organic garden.
