This field day is part of MGA’s ongoing efforts to provide organic grain growers with firsthand exposure to how their crops are cleaned, processed, marketed, and transformed into finished products. In addition to seeing the operation at Maine Grains, attendees will learn about the quality standards, infrastructure needs, and buyer expectations for organic grains in Maine.

As part of MGA’s ongoing efforts to support organic/transitioning grain growers, we are now hosting office hour sessions with experts on all sides of the regional grain economy. 

About the Presenter:

Tom Molloy is a Research Professional in Sustainable Agriculture at the University of Maine and is the small grain and pulse crop specialist for Cooperative Extension with 20+ years of experience. Tom will discuss the basics of organic grain production including fertility, crop selection, rotations, planting and harvesting fundamentals, weed control and post-harvest handling. This session will begin with a thirty minute group discussion after which participants are invited to schedule an individual or small-group consultation with Tom.

This workshop explores corn from its earliest origins in Central America to its modern role in sustainable and organic food systems, with a focus on how growing choices connect to end-use and how intentional growing (especially organic & heritage varieties) supports better food, stronger markets, and long-term resilience in regional grain systems.

Dr. Dusty Dowse will begin the session with an overview of corn’s archaeological history and traditional practices like nixtamalization.

Following this, Rafael Mier (Fundación Tortilla) will lead a hands-on masa & tortilla-making demonstration.
