Northwest Iowa — Drought conditions are expanding across the state, spreading throughout southern Iowa, with northwest Iowa being hit hardest.
Don Kass farms in Plymouth County, which is in extreme drought. He says his crops have been faring well so far, but he’s starting to see signs of heat distress.
Kass says it’s a critical time for corn and soybean development. He says the area needs to see significant rainfall soon to aid the crops’ pollination process. This year, the region saw its second driest June on record, what’s typically the wettest month of the season. On a daily basis, Iowa State University Extension field agronomist Joel DeJong says he sees corn leaves curling and soybean leaves turning over to protect themselves from the heat.
DeJong says he expects the region’s yields will be impacted more than they were during last year’s drought. That’s due to a prolonged period of higher temperatures. Compared to last year, the region has seen more 90-degree weather. The latest U.S. Drought Monitor map shows around 60 Iowa counties are in some form of drought, with 30 counties abnormally dry, 20 counties in moderate drought, six in severe drought and four (Cherokee, Plymouth, Sioux & Woodbury) in extreme drought.
