Even with this recent slowdown, Illinois soybean is ahead of most of the Corn Belt, with 57% of the soybean crop planted by May 10, up 11 percentage points from the previous week. This is also well ahead of both last year (48%) and the five-year average (47% for 2021-2025). Corn planting has also progressed at a near-normal pace, with 54% planted by May 10, up 16 percentage points from last week.

What to watch as soybean planting begins in 2026
March was wetter than normal across much of Illinois, with statewide precipitation averaging 4.85 inches, 1.91 inches above normal. The wet trend continued into the first two weeks of April, particularly in northern Illinois, which has received between 3 and 5 inches of rainfall since April 1…
The 2025 growing season in Illinois: good but not great
The 2025 growing season in Illinois delivered another storyline characterized by sharp weather contrasts, average crop condition ratings, some disease pressure in places, and very good — if not record-setting — yields in many, but not all, areas. As we have seen before, crops showed their ability to translate good mid-season conditions to good yields even with very dry late-season conditions…
Evaluating soybean performance in conservation systems – project update
This project aimed to evaluate whether growers can maintain productivity and profitability while using reduced tillage and cover crops, systems that protect soil but are often perceived as risky. A second objective was to understand whether starter fertilizer (nitrogen + sulfur) could offset early-season challenges in these systems, such as cool soils, heavy residue, and slower early growth.
Double-crop soybean management practices – project summary
There is a growing interest in wheat/soybean double-cropping systems in Illinois, extending into parts of central Illinois where wheat acreage has been limited in recent decades. This article summarizes findings from field trials evaluating management practices for double-crop soybean in central Illinois
The 2025 soybean crop as we approach harvest
While August rainfall is the “soybean maker,” July rainfall is also important to the podsetting process that sets up yield potential. July rainfall was plentiful overall in Illinois, but varied from an inch or two less than normal in parts of southern Illinois to more than twice normal amounts in western and northwestern Illinois…
Another bin-busting corn year in Illinois approaches maturity
It was no surprise to see the 2025 corn yield projected at 222 bushels for Iowa, but it was surprising to see 221 bushels projected for Illinois. Ihe US yield is predicted to be 188.8 bushels per acre, 9.5 bushels higher than the previous yield record, set in 2024. So, while 2025 is set to be a great year for corn, we will consider here what it will take to achieve such high yields and what might prevent them from reaching such high levels, at least in some places…
Planting and early-season corn and soybean progress – 2025 update
Overall, crop stands are good to very good across most fields, reflecting the relative freedom from heavy rain, flooding, and crusting after planting. By the beginning of June, corn that had been planted in mid-April in northern and west-northwestern Illinois was just beginning to accelerate stem growth – the process that initiates rapid growth and nutrient uptake…
Optimizing corn and soybean seeding rates
Seed costs for corn and soybeans have risen considerably in recent years, along with genetic yield potential and improved ability of planted seeds to emerge and establish productive plants. Here we reviewed seeding rate trials to highlight what works best in Illinois.
Have we missed the best planting window for 2025?
The dry weather had fields in some places dry enough to work and plant around the middle of March, and although NASS did not report any acreage of corn and soybeans planted as of March 30 (they typically use 1% as the threshold), we know that some fields were planted by the end of March. Should more have been planted?
