After everything our crops have been through this growing season, we are checking in to discuss what impacts weather, delayed planting and other forces have had on crop development. Dr. Stephanie Karhoff joins us to provide a perspective from across Ohio.

Planting season are never normal and 2026 is no exception. With the southern half of Ohio nearing completion and the northern half struggling to make headway, there was a lot of crop variability as below freezing temperatures hit the state. Expected prolonged cold and wet weather as another wrinkle. Dr. Jason Hartschuh, Field Specialist with OSU Extension, joins us as we talk about the potential impacts on corn, soybean, wheat and alfalfa. We share what to look for now and in the coming weeks as we deal with a cooler, wetter May.
This CORN Newsletter has two articles on freeze impacts to soybeans and wheat: https://agcrops.osu.edu/newsletter/corn-newsletter/2026-12. The Purdue photo gallery on freeze damage can be found at: https://www.agry.purdue.edu/ext/corn/news/articles.01/Frost_Corn_Soy-0418_Gallery.html.

Slug pressure has become an increasingly common and frustrating challenge in crop fields in recent years, driven by wetter springs, heavy residue, and changing production systems. In this episode, we dig into why these slippery pests seem harder to manage than ever. With Kelley Tilmon joining us, discuss the limitations of traditional control options and what growers should realistically expect from different management strategies. From scouting and risk factors to cultural, biological, and chemical tools, we’ll break down what we know and how to make informed decisions when slugs start putting your stand at risk.

Two farmers, Fred and Josh Yoder, discuss one conservation focused research project developed by a group of farmers in Ohio. They are part of a multi-state, four-university effort to discover how to increase conservation adoption on farms. Our farmer-led team is working to improve real-world, on-farm performance of conservation practices to ensure they better generate the outcomes – e.g. profitability, yield stability, and protection from extreme weather events – that farmers need.

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.

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.

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.

Agrivoltaics is combining agriculture and solar energy production. In partnership with Savion Energy, we were awarded a Department of Energy grant to investigate the feasibility of forage production, grazing and impacts on solar health at the Madison Fields solar site near Rosedale, Ohio.
In this episode we share the details of the project and what we have learned so far in our first growing season. You can follow along on our progress at Energize Ohio.
