SYNOPSIS

With little rain over the past week, perhaps a few tenths over the weekend, soil conditions in most of Champaign County are on the dry side. However, most fields of both corn and soy look relatively healthy with minimal external signs of drought stress. Measurements from the local Illinois Soil and Water Survey monitoring station show plant-available soil moisture at depths of 8+ inches, and it seems that most crops in the area have been able to reach some of that deeper soil moisture. That said, signs of drought stress including stunted plants and dying lower canopy leaves can be found in compacted areas of fields as well as the few hilltops we have in the county. Tip dieback and ear size was variable in the corn fields I surveyed, and most were in the late R3 (milk) growth stage moving into early R4 (dough). Soybeans were generally around R5 (beginning seed).
