Dependable Source for Organic and Certified Transitional Food-Grade Corn and Soybeans

Clarkson offers three colors of organic and Certified Transitional food-grade corns, organic and Certified Transitional soybeans, and a variety of organic and Certified Transitional feed grains and ingredients. If you are buying organic or Certified Transitional grains, please contact us for pricing and availability.

When the organic movement was in its infancy, Clarkson was already working with organic buyers to build and integrate a reliable supply system with farmers committed to organic farming. And we were also helping IP (Identity-Preserved) farmers transitioning to organic.

As one of the premiere grain companies to become certified, Clarkson has followed the trends of this ever-changing market, and continues to support the organic and Certified Transitional industry at many levels. Clarkson founder and President, Lynn Clarkson, served as Director of the Organic Trade Association for seven years. He has also served on many committees for the NOSB (National Organic Standards Board), and is a speaker at many organic trade shows and conferences.

For growers all across the Midwest, we offer contract opportunities for organic and Certified Transitional corn and soybeans. If you are currently a Certified Organic or would like to become a Certified Transitional grower, please contact us for opportunities to grow for, and with us.

Definition of Organic Certification


National Organic Program

Clarkson has had organic certification since 1998. Defined by the the Organic Foods Production Act of 1990, organic certification is a process audited on an annual basis by the United States government for producers of organic foods, crops, and other organic agricultural products.

In general, any business directly involved in food production can be certified, including seed suppliers, farmers, food processors, retailers and restaurants. Requirements vary from country to country, and generally involve a set of standards for growing, storing, processing, packaging and shipping.Synthetic chemical inputs are prohibited, such as fertilizer, pesticides, antibiotics, food additives, genetically modified organisms (GMOs), irradiation, and the use of sewage sludge.
