For many parts of Ohio, water management used to mean draining water off a field. Today, with drier summers, it can mean a wider range of activities. Dr. Vinayak Shedekar is the state specialist for agriculture water management. He has conducted extensive research in not only drainage, but many aspects of field water management.

In this episode we will talk about current trends in water management, what research is underway and what farmers can expect from the future of the drainage industry. For more information, please visit: go.osu.edu/agwater.

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.
