Very scattered rain July 1-4 across the region. Reports of no rain to 6 inches in locally heavy spots. Rain was spotty as you may have got rain on this quarter section and not the next. On our own farm we had one rain event where we had 4 tenths on one field and basically 0 half mile down the road on another. Despite the rain we are far from out of the woods on drought. The moisture hasn’t meet yet on our own farm and most others across S Illinois.

Lots and lots of questions on April planted corn. Some 4 ft tall and trying to tassel, most without any silks. In some fields silks out but no tassels. We are seeing root issues in the dry soil, some of the storms root lodged the corn and it has nothing to hold onto with the dry conditions. Late May and June planted corn still has a fighting chance. Some fungicide is going on, but I am not sure why at this stage, there is no disease pressure and in some cases, we don’t really have a viable host.

Early planted soybeans have maybe 9 nodes in some fields and have never closed the rows on 15 inches. Heard the seed production guy say he has never seed blooms “on the ground” because plants are so short. Later planting and later maturity are doing better. Spider mites are showing up in many places.

2023 harvest is shaping up to be a highly variable mess. There will be fields of good/average yields next to almost complete disasters based on planting date and what cloud it was under when.

Corn pollination is taking place. Soybeans will be approaching R3 (pod set) soon. Both corn and soybeans will be at the correct growth stage for fungicide and insecticide in about a week. There appears to be a lot of waterhemp escapes. Also saw minor corn snap and lodging.

This week started with drought and wildfire smoke and ended with ponds in the field. Southern Woodford County had 2.5 inches of rain over two separate storms a few hours apart. The first storm was in the overnight hours and had small hail. The second storm was an intense downpour. We were lucky to not have damage to the crop in this area. Next week will be focused on which weeds are germinating and what we can do about it. The herbicide options are limited and may or may not control the weeds emerging. Cultivation is an option in organic or later planted beans that are not close to the rows closing. Read the herbicide label for crop growth height and stage restrictions.

Much of the corn in NW IL was starting to roll and pineapple on late last week. The rain over the weekend and cooler conditions reduced this impact through mid week. Many fields of corn and soybean field seem to be behind in height and canopy closure at this point. Some of the early planted field which received timely showers during May and June look more normal. This really shows the spotty distribution of late spring showers.

We have been dry again this week, having missed any potential rain chances that were predicted. Our temperatures have also warmed up with most days at 90 degrees or above for highs. This has really put the stress to crops especially in the afternoon. Overall, crops look fairly good considering the dry, but they are growing fairly slow. Some early planted corn in the river bottom is starting to tassel. Wheat harvest is wrapping up and all reports I have heard have had very good yields and quality. Double crop soybeans are emerging fairly well, but they along with everything else, will really be hurting if we continue to stay hot and dry.

Much-anticipated rainfall fell across much of central Illinois on Thursday, June 29, accompanied by high winds and hail in some places. More rain is forecast in coming days, and we hope this means an end to the drought of 2023. It would be better if the rain came more slowly without hail, but we won’t complain. Two inches or so of rain over the next two weeks should be enough to get corn through pollination in most fields, and to get soybean growth and yield potential back on track.
The fact that corn has stayed relatively short and plants are not as brittle as they would have been with more soil moisture should help the crop withstand windstorms. Short corn can have high yield potential, as long as canopy cover is complete by pollination, and leaves remain healthy. Lower leaves that have lost color may not come back, but nutrient uptake and color of larger leaves should get back to normal. We can expect soybean leaf area to develop rapidly, and having the plants shorter than normal with less internal shading may help pod development and retention as plants continue to flower over the coming weeks.
Rainfall should bring a quick reversal of the recent decline in crop condition ratings of both corn and soybean. Answering the question about whether yield potential has been irreversibly lowered by stress will get easier over the next few weeks as plants resume growth and canopy development. We do expect yield potential to recover well, if perhaps not fully in those fields most affected by drought up to now. That will be helped along by normal rainfall, temperatures, and sunlight in July.

The area received some much-needed rain. The ISWS weather stations in Bondville and Champaign recorded 1.12″ and 0.85″, respectively. On my drive back from a field day in Christian County (after riding out the storm in Pana) the storm damage appeared to be isolated largely to toppled trees and fallen limbs. While there was generally an eastward lean to most of the corn fields, I did not see any greensnap or large areas of flattened corn, at least on the field margins. The images below, taken between Villa Grove and Philo in Champaign County, are from a corn field with the most severe wind damage I found. Some of the corn is on the ground, but most plants looked to still be well-rooted and will likely stand back up over the next several days, albeit a bit “goose-necked”. Soybean fields looked unharmed and and still generally in the R2 phase. But they will likely put on quite a bit of growth and start setting some pods in the next couple weeks with more adequate moisture now available.

Some fortunate NE farms received up to an inch of rain this past week. The rainfall helped our soy crop initiate new trifoliates, improving field aesthetics by hiding leaves present when post-herbicides were applied, giving some fields a “dinged” appearance. While recent rainfall was welcomed, signs of a very dry early vegetative season, and drought conditions, persist. Corn and soy are smaller than normally expected as we near July in our region. The competition for early season soil moisture is evident in corn fields having trees on their perimeter. Wheat harvest has yet to start in northern Illinois.
