March was relatively warm and dry in Illinois, and corn planting started early: NASS reported that 1% of the Illinois corn crop was planted by March 31, and 2% by April 7. Those are no record-early starts, but it’s rare to have enough planted acreage to report by April 1. Most of the state has had above-normal rainfall for far in April, so we expect limited planting progress in the coming days.
In this article we’ll consider a few nitrogen-related issues to keep in mind as planting progresses in 2024:
Due perhaps to an article in the Ohio State C.O.R.N newsletter this week,…

While statewide precipitation in March averaged 3.21 inches (89% of normal), we saw a clear north-south gradient within Illinois, with totals ranging from half to an inch above normal in the northern part of Illinois to as much as up to two inches below normal in the southern end of the state. April began with above-average precipitation across the state, with 7-day totals averaging almost 2 inches,…

The Insect Trapping Network provides real-time information to growers through Illinois during the growing season.  As in past years, our spring traps focus on black cutworm and true armyworm moths. During the summer months, our focus switches to corn earworm, European corn borer and fall armyworm.
We are currently looking for cooperators to monitor both black cutworm and true armyworm traps from April 1 – May 31. By placing traps around the state, we are able to provide information on pest populations as they move into the state and predict timing of potential injury.…

An article in the online Prairie Farmer on October 11, 2023 titled “How much nitrogen does corn get from fertilizer?” followed by the subheading …”80% of a corn crop’s N comes from the soil…” This has caused a great deal of discussion and consternation among those who sell and use nitrogen fertilizer on corn.
The basis for the article was a May 2023 news release from the University of Illinois College of ACES, which summarized findings from several studies conducted in the Department of Natural Resources and Environmental Sciences by Dr.…

Soil Conditions: Moderately Dry (soil is dry, plants may be browning or stressed, water bodies are low)
Corn is at R5 (dent), and most soy is at R6 (full seed). Fields that still have green tissue are benefitting from recent rainfall. Areas that experienced drought conditions after pollination and during grain fill can expect corn kernel abortion near the ear tip and smaller and lighter kernels.…

Rainfall in the first two weeks of August recharged soil moisture across much of Illinois, but since then, the combination of low rain amounts and very high temperatures (4.7 to 8.9 degrees above average) brought on some stress during the last week of August. The August 29 U.S. drought monitor map from last week showed about 43% of the state with no stress, 42% abnormally dry, and 15% with moderate drought. Parts of central and southern Illinois received between 0.5 to 1.5 inches of rain this week,…

Winnebago County
Soil Conditions: Mildly Dry (soil is drier than normal, plant growth may have slowed)
This area has not seen rain in over two weeks and is not forecasted again until 9/6. Disease presence is still low as a result. The dry conditions were exacerbated by high temperatures (upwards of 97 degrees F) last week, which we will see again this weekend. Corn is dented (R5),…
