About the Webinar
Learn about the foundations of seed cleaning in this practical, 90-minute webinar. Whether you’re processing small batches for on-farm use or scaling up for commercial production, understanding seed cleaning is essential for seed quality and efficiency. This session will introduce the key principles of cleaning both wet- and dry-processed seeds, including threshing, winnowing, screening and fermenting, drying, and storage. Presenters will share hands-on experience with crop-specific methods. Participants will gain insight into how to improve seed quality, reduce labor, and develop processes that fit their farm’s size and production goals.
