Does This Product Work?

April 6, 2021
Emerson Nafziger

“Every agronomic decision is a good one for someone” is a quote that I saw recently that reminds us that being “entrepreneurial” is high valued in today’s business world, rewarded in some cases by large amounts of venture capital invested in startup companies. That’s as true in crop agriculture as in any other business, and it means that startups are under pressure to find or create niches and product(s) to fill them, and to demonstrate that these products are widely sellable.…

Planting-time Considerations

March 23, 2021
Emerson Nafziger

March rainfall in Illinois has ranged from as much as an inch below normal in the northern third of the state, to close to normal in central Illinois, to as much as 2 to 3 inches above normal in the southern third of Illinois. This, along with some rain this week, has dampened the hope for a March start to planting in most areas. That gives us time to think about issues related to planting and early-season management.…

CropFlix 2021- Illinois’s Virtual Crop Management Conference- Launches February 1

January 28, 2021
Chelsea Harbach

I received a notification on my phone this past Wednesday letting me know that it was the date of the Crop Management Conference in Macomb- the location I was going to be in charge of for the 2021 series of meetings. At some point last year, I put that date in my phone, optimistic about the chances of having face-to-face meetings during the winter of 2021. Sadly, as 2020 marched on, my optimism for 2021 marched away.…

Make Sure You Know ALL the Changes for 2021 Dicamba Applications in Soybean

January 14, 2021
Aaron Hager

In late October 2020, the United States Environmental Protection Agency (US EPA) announced new five-year registrations for the dicamba-containing products XtendiMax, Engenia and Tavium. These labels include new and/or additional application restrictions that were not included on previous labels. Annual dicamba-specific training (which we hope begins soon) offered by the product registrants will undoubtedly cover many/all of the new label changes, but there are a few changes that some currently might not be aware of and might come as a bit of a surprise. …

Soil temperatures and fall ammonia application

October 26, 2020
Emerson Nafziger

As we indicated in a recent Bulletin article, nitrogen applied as anhydrous ammonia in the fall is an effective source of N for the corn crop, but is also a little more subject to loss compared to N applied in the spring. One of the main factors that determines how much of the fall-applied N is subject to loss is how much of the ammonia converts to nitrate (is nitrified) in the fall and early spring,…
