Maize (corn) is an incredibly productive and profitable crop that works well in organic crop rotations in many parts of North America. Since the release of transgenic (GMO) varieties of maize in the mid-1990s it has become increasingly difficult to grow uncontaminated organic maize or to find maize seed that is free of transgene contamination. 
Plant diseases, especially those caused by soil-borne seed infecting pathogens, pose a serious threat to the production of both greenhouse and field crops. Conventional farming operations often use fumigants and chemical seed treatments, which can be harmful to human health and the environment, for controlling seed and seedling pathogens.
Very little sweet corn grown commercially today is open pollinated. Farmers who wish to save their own seed have few if any good choices of varieties to grow. And the hybrids of today have been developed for conditions that are different from those found on most organic farms, as they were selected to rely on fungicides and pesticides, and to effectively utilize soluble synthetic fertilizers in large quantities.
Identifying appropriate varieties for organic production in the mountains of Western North Carolina is considered a research priority by local growers.
There are two obvious barriers organic producers face when they consider on-farm processing. The first is psychological. On-farm processing can appear intimidating and beyond reach, on one hand; on the other, it may seem unnecessary to someone who is already “adding value” by raising crops or livestock organically. The second barrier—a more pragmatic one—is the lack of good, producer-friendly information on small-scale organic processing and handling.
