This includes Iowa, and states with even worse crop conditions, such as Illinois and Indiana.

For the next week, high temperatures will continue to run at or near triple digits, which is about 12 degrees hotter than normal.

The combination of extreme heat and prolonged lack of moisture creates a double-whammy for feeding grasslands, as well as local corn and soybean fields.

“Now, the fields have accumulated a lot of heat. It’s attacking day after day after day,” said Tracy Cameron, agronomist for Gavilon Ag Service. “It’s kind of like having the flu. You can weather one day of it. But if you have it for three weeks, it wears you down.”

Cameron said there are visible signs of heat stress, particularly in cornfields.

“When it’s way too warm in the daytime, and it doesn’t cool down at night, the corn expends too much energy trying to stay alive,” Cameron said. “It does things to the yields. The plants end up aborting some of the kernels. There were also some pollination problems for some of the corn planted later.”

In rows of 6-foot tall corn, there are signs of stress. Leaves are rolling — corn’s self-preservation technique to conserve moisture — and the ears are small. Some cornstalks are “firing” — drying out and turning brown from the roots up. That normally doesn’t happen until September.

“That’s a sign the plant is pulling nutrients from those areas to feed the ear and keep the plant alive,” Cameron said. “It progresses up the plant the longer it goes without moisture.”
