USDA Publishes New National Organic Program Guide

The first edition of the U.S. Department of Agriculture's handbook for the organic sector was published on Sept. 2, 2010. Prepared by the National Organic Program (NOP), the handbook provides guidance about national organic regulations for those who own, manage, or certify organic operations. It is intended to serve as a resource for the organic sector to help participants comply with federal regulations. It is available online at Printed copies can be made available upon request to the Standards Division, National Organic Program, 1400 Independence Ave., SW., Room 2646-S, Ag Stop 0268, Washington, D.C. 20250-0268; telephone: (202) 720-3252; fax: (202) 205-7808. 

The handbook provides guidance on the allowance of green waste and approval of liquid fertilizers in organic production systems; certification of organic yeast; processed animal manures in organic crop production; reassessed inert ingredients; and the calculation of dry matter intake to verify compliance with the NOP's pasture requirements. It also includes instructions concerning organic certification, such as recordkeeping, steps to certification, and organic certificates; accreditation procedures, such as how to apply to become an accredited certifying agent; international procedures, such as how USDA determines equivalence of foreign organic standards to those of the NOP; compliance and enforcement measures, such as how to handle complaints; and appeals procedures for certified operations or accredited certification agents.

The handbook explains the difference between NOP regulations and guidance/instruction documents and outlines their purpose, legal effect, and the process by which the NOP authorizes, reviews, revises and disseminates them to the public.

Study Compares Fruit and Soil Quality on Organic and Conventional Farms

A recent 2 year study of organic and conventional strawberry farms in 13 California agroecosystems found that organic strawberry farms produced higher quality fruit with longer shelf life and greater concentrations of certain nutrients such as ascorbic acid. The researchers, who included eOrganic members John Reganold, Jennifer Reeve, and Lynne Carpenter-Boggs, also found that the organic soils contained more carbon and nitrogen, as well as greater microbial activity and biodiversity.  The full text of the study is available online at:

New Publication Summarizes Health and Environmental Benefits of Organic Food Production

eOrganic certification group leader Jim Riddle and Bud Markart of the University of Minnesota recently released a 6-page publication entitled  What is Organic Food and Why Should I Care? which explains USDA National Organic Program requirements in simplified terms. It also presents footnoted summaries of scientific studies about the health and environmental benefits of organic food and farming.

Spread the Word

bullhornIf you would like eOrganic literature to hand out at your next conference/workshop/house party, please get in touch. We have bookmarks, factsheets, brochures, and even displays you can use! Use our online form to request materials

Research-Outreach Groups (eOrganic's collaborative workspace) provides space and support for the work of organic research/outreach project groups. These groups can be lab groups, project groups (e.g. SARE and NIFA OREI projects), and even graduate courses! All group members can become members of and participate actively in groups, including farmers, agricultural professionals, students, and non-profit staff. The workspace allows groups to share files and images, make decisions (forums), and collaborate on outreach materials, proposals and manuscripts. Groups are also beginning to use eOrganic's web conferencing tools to hold virtual seminars and field tours. If you are interested in learning more about how to use to manage your group, contact John McQueen.
