Fields in LaSalle County have dried out a bit over the last week, with only minimal rainfall over the weekend. At the IVCC + Extension Research and Demonstration Plots corn is nearing V5 and soy V1-2. Other fields scouted in LaSalle County have V6 corn and V2-3 soybeans.

Dry conditions in northern and central parts of Illinois allowed for a relatively early start to planting this year; the first NASS report of planting was soybeans at 1% on April 6. Soybean planting stayed ahead of corn planting through April, with 22% of soybeans and 16% of corn planted by April 27. By May 4, planting progress was nearly even—33% for soybeans and 32% for corn.…

Winnebago County
Soil Conditions: Mildly Wet (soil is wetter than normal, local vegetation is healthy)

Stephenson County
Soil Conditions: Mildly Wet (soil is wetter than normal, local vegetation is healthy)
Across the county, corn is between VE and about V4 while soybeans are yet to emerge or at about V1. The rainfall received over the past couple weeks has been well received – the crop looks healthy and green. Surprisingly given the rain, there aren’t yet any significant weed flushes, but scouting is recommended to identify any moving forward.…

LaSalle County
Soil Conditions: Moderately Wet (soil is damp, standing water may be present in low areas, water bodies are full)
It has been a wet and chilly week following the hot, dry weather last week. LaSalle County saw nearly 5 inches of rainfall, which has led to ponding in some of the more low-lying areas of fields. Nearly all corn acres are planted, with most corn around stage V1-V2.…
