Soil Conditions: Moderately Wet (soil is damp, standing water may be present in low areas, water bodies are full)
After a wet finish to last week and more systems moving through over the weekend, we have some very wet and saturated soils across northern Illinois. Corn and Soybeans continue to dry down, but that has slowed with the rain and cooler weather moving in.…

Soil Conditions: Mildly Dry (soil is drier than normal, plant growth may have slowed)
Rain is expected for Northeast Illinois this week, if it materializes it will provide needed moisture. Its benefit to most crops at this stage is uncertain, but we will decrease the fire risk associated with starting harvest when crops are tinder dry. It’s becoming a challenge to share information on the 2026 crop;…

Soil Conditions: Near Normal
Cooler and wet conditions have moved in across northern Illinois. Light rain and heavy morning dews have propagated some late season disease in both corn and soybeans as we start to enter wide-scale senescence and harvest.
Soybeans in McHenry and DeKalb counties are producing large amounts of pods, as well as filling those pods very well. I expect many soybean fields to have high yields.…

Soil Conditions: Near Normal
Entering September an intense shift in weather as a “heat dome” became established in Northeast Illinois. While fields near the Wisconsin state line received precipitation, most areas did not. The ninety degrees plus days provided ample Growing Degree Days (GDDs) for crops finishing grain fill. On lighter soils the temperatures are causing a water deficit reflected by the wilting/yellowing plants.…

Soil Conditions: Mildly Dry (soil is drier than normal, plant growth may have slowed)
We have caught a very nice break from severe weather and storms, with some pleasant temperatures to boot, as we begin to enter the home stretch of the growing season. Corn fields across northern Illinois are starting to fire, while soybean fields continue to stay green and produce large pods and seeds.…

Soil Conditions: Mildly Wet (soil is wetter than normal, local vegetation is healthy)
The heavy storms and even a derecho have passed, and we have been left with some gorgeous weather to end the week before some more rain chances next week. Not too many updates agronomically from my last update. Corn has moved into R5 dent across northern Illinois, with many fields at the early stages of senescence.…

A very active weather pattern across northeast Illinois that spawned tornados, a derecho, and significant rainfall and flooding across the region. In corn fields, foliar leaf diseases are now more easily detected, including Southern rust. A Southern rust report was received by Dr.…

Quick synopsis of conditions that will appear in the main feed
After yet another heat wave, we finally received some reprieve with some consistent rain and cooler temperatures. We were briefly entering a drought across most of the region but have come back to normal after this past weekend’s rain.
Most corn fields I saw are between R3 (Milk) and R4 (Dough).…

Soil Conditions: Near Normal
This past week saw hail, substantial rain, and missed opportunities for needed precipitation in varying fields across the northeast region of Illinois. Corn has reached R3 or the milk stage in the field I have been scouting this summer. At this stage the kernel no longer adds new cells to the kernel endosperm but fills the existing cells with liquid starch.…

After a busy July, I am back with another crop report. We are coming out of a very significant heat wave. Northern Illinois is entering a mild drought with little to no rain in the foreseeable future, and the Canadian wildfires smoked most of us in Northern Illinois out for the tail end of the week and well into the weekend.…
