Another week of slightly cool days with scattered storms has Iowa farmers facing uneven stands in many fields. Cumulative heat during the week of June 23 lagged behind long term averages by 10 to 25 degree days in Iowa. The cool temperatures and still wet soils provide stresses to struggling crops, and those stresses are showing up in poor growth. As we get more heat the corn and soybean should recover, but this early summer has predisposed the crops to future stresses.
