The 2024 growing season was somewhat unusual in Illinois, with overall conditions good enough to produce record-high corn and soybean yields. The September estimate of corn yield in Illinois is 222 bushels per acre, down three bushels from the August estimate. Soybean yield is projected to be 65 bushels per acre, one bushel less than the August estimate. These declines may reflect the increasing dryness in the state over the past weeks. With early-planted corn and soybean at or near maturity,…

Ratings for the 2024 Illinois soybean crop have been high most of the season, and the August 1 estimate released by NASS is for yield at average 66 bushels per acre. That would be a new record for Illinois, 2 bushels higher than the 2021 yield, and 4.9 bushels higher than the 2024 trendline yield.
While the soybean yield prospects are good, this has been an unusual year, and this lets us watch how the crop’s response to the weather is playing out in the field.…

Wet weather delayed planting of some of the 2024 Illinois corn crop, but stands (except in drowned-out low spots) are generally good. Warm, dry weather in June caused some water stress in places, but kept development moving and helped roots to establish. July-August rainfall totals have been above normal for almost the entire state, while temperatures have been normal to a little below normal.
Reflecting the favorable weather this growing season, the August 1 estimate of yields,…

Although April-May rainfall exceeded normal amounts in Illinois by up to 50 percent in some areas, and average temperatures have exceeded normal by several degrees, the weather record fails to capture what the 2024 planting season actually looked like. Planting in parts of the state was nearly complete by early May, while in other places, many acres remain to be planted going into June.
Planting began early, with 1 percent of both corn and soybeans planted in Illinois by the end of March.…

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,…

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.…

Planted wheat acreage in Illinois increased by 35%, from 650,000 acres in 2022 to 880,000 for the crop to be harvested in 2023. Wheat acreage by county or crop reporting district is not available, but indications are that some of the additional acreage is in parts of central Illinois where wheat acreage has been limited in recent decades. Wheat yields in Illinois were record-high (79 bushels per acre) in both 2021 and 2022, which along with high wheat prices added to expectations that wheat would be a profitable crop in 2023.…

The first half of April was dry and warm in Illinois, and 159 growing degree days accumulated, compared to the average of 99. The second half of April was also dry in most areas, but only 92 GDD accumulated, compared to the average of 132. Some producers who would normally plant as fast as possible during the second half of April decided to delay planting due to low temperatures. That’s very unusual when soils are in good working condition,…

By April 16, 10 percent of the Illinois corn crop and 4 percent of soybeans had been planted. Rainfall across Illinois is below normal so far in April, with an unprecedented 10 (of 20) days with no rainfall recorded anywhere in the state. Topsoil moisture ranges from slightly above to slightly below normal across Illinois; there are no areas of really wet or of really dry soils. Some rain fell over the last 24 hours, but little rain is forecast for the next week.…
