Episode 144 – Dealing with DON

by at

There is nothing more frustrating than getting rejected at the elevator due to high vomitoxin (aka DON) levels. DON is produced by a fungi produced on the ear and is usually infected at the time of pollination. To give farmers a better perspective of what happens behind the scenes at a grain elevator, we interview 3 grain merchandisers on their process when DON test levels start creeping up.

Jason Beckman (Poet), Lisa Mitchell (Gerald Grain), and Seth Miller (The Anderson) take us behind the scenes of their operations to look at testing, grain flow and market impacts. We end with some quick reminders about DON management and to check the C.O.R.N. Newsletter for updates and research on corn fungicide and disease.

Episode 129 – Farming the first Thanksgiving

by at

With this episode releasing right before Thanksgiving, we wanted to celebrate by diving into how the food eaten during the first thanksgiving over 400 years ago came to be. While farming was simpler in a lot of ways, it is intriguing to consider what the pilgrims were up against trying to survive in a new land and how the Native Americans had adapted to raise and protect crops without today’s modern technology. This is a fun one to put on in the car with whole family as you head to Grandma’s house. Happy Thanksgiving!
