Organic Agriculture Resources

Overview of Organic Agriculture

Organic Agriculture is a holistic farming system that emphasizes environmental sustainability, biodiversity, and the health of soils, ecosystems, and people. It relies on ecological processes, natural inputs, and biological activity, avoiding synthetic chemicals and genetically modified organisms (GMOs).

Overview of USDA Organic Certified Agriculture

USDA Organic Certified Agriculture is a federally regulated system of food and farming that emphasizes sustainability, ecological balance, and conservation of biodiversity. It is based on strict production standards and enforced by the National Organic Program (NOP) under the authority of the United States Department of Agriculture (USDA). The legal foundation for this program is the Organic Foods Production Act (OFPA) of 1990.

Organic Foods Production Act (OFPA)


Passed as part of the 1990 Farm Bill, the Organic Foods Production Act (OFPA) established:

  • A national framework for defining and regulating organic food.
  • The requirement for the USDA to create and maintain the National Organic Program (NOP).
  • Consistent, enforceable standards for the production, handling, and labeling of organic products.
  • The National Organic Standards Board (NOSB) to advise the USDA on allowed and prohibited substances and overall program development.

OFPA ensures that all organic products in the U.S. meet the same baseline standards and are verified through certification.


Core Elements of USDA Organic Certified Agriculture

Organic System Plan (OSP)


All certified operations must submit an OSP that outlines:

  • Production methods and inputs.
  • Soil and pest management practices.
  • Record-keeping and traceability procedures.

This plan is reviewed and updated annually.

Prohibited Practices and Substances


Under OFPA and NOP rules, certified organic operations may not use:

  • Synthetic fertilizers and pesticides (unless specifically approved).
  • Genetically modified organisms (GMOs).
  • Sewage sludge or ionizing radiation.
  • Antibiotics or growth hormones in livestock production.

Approved Inputs


Organic producers can only use substances listed on the National List of Allowed and Prohibited Substances, developed with NOSB input and maintained by the USDA.

Soil and Environmental Health


Operations must:

  • Promote soil fertility through cover cropping, crop rotation, composting, and conservation tillage.
  • Protect natural resources such as water quality, native habitats, and biodiversity.

Animal Welfare Standards


Organic livestock must:

  • Be raised in living conditions that accommodate their natural behaviors (e.g., access to pasture).
  • Be fed 100% organic feed.
  • Be treated using natural or approved methods; routine antibiotics and hormones are prohibited.

Certification and Compliance


  • Certification is required for farms and processors selling more than $5,000 annually in organic products.
  • Inspections are conducted annually by USDA-accredited certifying agents.
  • Non-compliance can lead to penalties, suspension, or revocation of certification.

Labeling and the USDA Organic Seal


  • “100% Organic” – All ingredients are organic.
  • “Organic” – At least 95% of ingredients are organic.
  • “Made with Organic Ingredients” – At least 70% organic content (no USDA seal allowed).
  • Only qualifying products may display the USDA Organic Seal, a mark of verified compliance with national standards.

Benefits of USDA Organic Certification


  • Consumer Trust: Backed by federal law and inspection, the organic label provides transparency and integrity.
  • Environmental Stewardship: Promotes practices that restore and preserve ecological health.
  • Market Opportunities: Certified operations gain access to a growing, premium organic market domestically and internationally.
  • Animal Welfare: Strong standards protect the health and natural behavior of livestock.
