Refined Boron for Organic Farming

U.S. Borax: OMRI Listed® for Organic Crops

For organic growers who require refined boron, U.S. Borax fertilizers are listed appropriate by the Organic Materials Review Institute (OMRI). This international nonprofit organization determines which input products are acceptable for use on certified organic crops under the USDA National Organic Program and Canadian Organic Standards.
 
As OMRI Listed® products, U.S. Borax fertilizers are an appropriate fertilizer and soil amendment for organic crops that are boron deficient. OMRI is ISO 17605 accredited as a material review organization, so certifiers can accept the OMRI Listed® Seal anywhere in the world. For more information about OMRI, visit https://www.omri.org.
