"SoDak Labs' Seed Biology course was an excellent source of foundational knowledge of seed biology and how it relates to seed quality and field performance. I've worked with CEO, Tim Gutormson, for over three decades and his knowledge of how seed biology and quality impact customer satisfaction is valuable to my company."
Douglas Krog -
"The team at SoDak Labs has come to know seed production and is not satisfied with what it is, but always looks to what can be better. They work with and teach how seed quality can be improved through adjustments in production processes."
