Episode 173 – All in on Harvest Data – Part 2

by at

We continue our discussion with Dr. John Fulton on how to increase the reliability of harvest data. This time we focus on the in-field practices. With bigger machines, it is getting more difficult to collect high res data. Tune in for recommendations on things such as how long passes should be and more to increase the quality of your yield data.

Episode 171 – All in on Harvest Data – Part 1

by at

Farmers write some big checks based on harvest data. How confident are you in the quality of that data? We’re getting into the weeds with Dr. John Fulton about how to ensure confident decisions can be made based on what is collected in the field this fall. In the first of this two part series, we talk about how yield measurements are collected in the combine, provide advice on calibration and discuss how unintentional mistakes can lead to big missteps with input decisions.

Episode 169 – Tar Spot in 2025

by at

Tar spot concern continues to grow across Ohio as it shows up in more and more fields each year. Each year farmers and researchers wonder if this will be the season it really explodes, causing widespread economic damage. For a background on Tar Spot, check out episodes 123 and 101.

In this episode, Dr. Stephanie Karhoff updates us on the latest research and treatment recommendations for managing not only Tar Spot but Gibberella ear rot and the vomitoxin it causes. Each disease has certain weather conditions and infection timing that are critical components to successfully managing it in field. The Crop Protection Network’s disease forecasting tool can afford insight into what to look for during scouting: https://cropprotectionnetwork.org/crop-disease-forecasting.

Episode 165 – Which to plant first?

by at

Each planting window brings the same question- Should I plant corn or soybeans first? Perhaps you have heard it referred to as the Battle for the Belt. Dr. Osler Ortez joins us for an update on his research based competition with soybean specialist Dr. Laura Lindsey to determine when the best windows are for planting corn and soybeans. They are also looking at where the largest yield losses occur when planting is delayed. These results can help farmers make decision on when to switch between corn and soybeans based on the calendar, maturity and conditions.

While fertilizer prices have come down somewhat, crop prices have many farmers considering where to cut budgets. Fertilizer can be an option and in this episode we talk about how to do it strategically. We cover where to start with soil testing, how lime might be your cheapest option and where to cut P and K if need be.

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 138 – Planting Green

by at

We caught up with Drs. Alyssa Essman and Dan Quinn at Conservation Tillage and Technology Conference to pick their brains about planting corn and soybeans into green cover crops. They share information on how to ensure good seed furrow conditions at planting and how to manage the cover crop at different stages. We also discuss herbicide strategies and advantages when planting green.

Episode 132 – 2023 eFields

by at

Our topic for this podcast is on-farm research and the 2023 eFields report. The eFields program is OSU Extension’s on-farm research network. Ohio farmers are encouraged to learn with us by partnering to conduct trials and share data through the annual report. Elizabeth give us a summary of the 2023 report and we talk with Wayne Dellinger and Nick Eckel, county Extension Educators and fellow contributors, about projects they have conducted over the years. 

You can view the 2023 report, along with previous years, at efields.osu.edu. The Knowledge Exchange provides unique ways to sort through all eFields research projects: kx.osu.edu/efields.

Episode 127 – Corn Drydown In-field

by at

Many areas are struggling with higher corn moisture levels than normal at harvest. While it may be tempting to leave corn standing to gain more natural drying, Elizabeth and Amanda will share why that is a high risk, low return venture.
