The NDSU Extension weekly podcast In the Pod: Soybean Updates delivers timely insights and expert advice on soybean production.
You're listening to In The Pod, soybean updates, a weekly trek into the latest soybean information from NDSU Extension. It's nearly the end of the year and a good time to recap the 2025 soybean growing season. Ana Carcedo, NDSU Extension agronomist, has the ups and downs of the year's growing season in part one of the 2025 growing season wrap up. Ana, let's start at the beginning of the 2025 growing season. How was the start up?
Ana Carcedo:If you remember, April was kind of warm, so a lot of farmers got that opportunity of planting really early. And that's always good when we talk about yield potential. The earlier that you plant, the higher the yield potential that you are going to get. But, of course, you have to take into account a lot of things. What happened following that warm April was not really warm. So we have cooled and wet conditions in May that pushed back planting a lot. It affected a lot the emergence and timing. We had a lot of problems not only with temporal uniformity, but also with special uniformity. When we say temporal uniformity, we're saying basically that plants started to come up in different times. That usually have an impact in our yields mostly because plants start competing with each other. You know? Like, they're kind of mean with each other sometimes. So there was a lot of replanting this season. Some northern and central areas require replanting due to this early port stands. Something that it was really highlighting the central areas was crusting. When we think about our systems, our farming systems, there is a huge component that's tillage. This has an incredible effect on crusting. When we work in no till systems, we have all the residue from previous crops that actually protect the surface of our soils. All that residue, what it does is kind of a cushion that protects from the impact of the raindrops. This is like the farming system that have no deal did not have these crushing problems. Crusting, again, was a huge problem this year. By late June, the emergence in the state hit 93%. That actually was close to the state average, So we were not that delayed, but we have those emergence problems. We keep thinking of how the crop condition was early in the season. 33% of the fields were qualified fair, which is not good. Around 50% of the fields were good. This is just showcasing again the resiliency of soybeans. We have a really rough start. We were able to catch up.
Bruce Sundeen:What other challenges did soybean farmers face?
Ana Carcedo:As we get quite a bit of rain and it was really wet, all old saturated soils show it. If you have carbonates in your soil and you have moisture, those carbonates dissolve to bicarbonates. They rise the pH of your soil, make the iron that's in your soil when available for the plant for uptake. You're going to see more IDC in these wet conditions. IDC was kind of one of the starts of the season. It really show up this year. When we're talking about IDC, also something that you have to consider is when you are seeing those symptoms. When you have five leaf completely expanded, three trefoliated leaves, you are going to start seeing yield penalties. So if your crop had IDC symptoms and you were, like, with five expanded leave, then you probably had yield impact. Something that you might consider even though we never know if we are going to have these wet conditions every year. So something that you might consider is using IDC resistant varieties, That's the best way to cope with these problems.
Bruce Sundeen:Thanks, Ana. Our guest has been Ana Carcedo, NDSU Extension agronomist. Next week, we'll continue with part two of the growing season wrap up and take a look into the 2026 growing season.
