Heat, dry conditions threaten Kentucky corn crop

About 30% of the state's corn crop is at a key point in its growth and also at its peak demand for water.

As the unrelenting heat continues across Kentucky, medical experts are reminding people to drink plenty of fluids and stay hydrated. But it’s not that simple for farmers who depend on Mother Nature to water their acres of corn.

Kentucky’s corn crop is in a critical moment.

University of Kentucky Extension Professor Chad Lee, who specializes in grain, said 30% of Kentucky’s corn crop is at a key point of growth.

“We’re right at the period of time where tassels come out and we go to pollination. And so that’s very sensitive for water stress in and of itself, but the corn is also at peak demand for water,” Lee said. “It’s going to demand more water now than it does at any other point in its life cycle.”

“This next seven to 10 days is absolutely critical for the corn crop. If we miss this window, we’ll have some severe damage to the corn yields around the state.”

Lee said less than 10% of Kentucky’s corn acreage is irrigated. He said that hasn’t been a major issue for the past 10 years, since the last severe drought that hurt the state’s corn crop was in 2012.

The hot and dry weather is also stressing Kentucky’s soybean crop, but Lee said soybeans can adapt better to the lack of water.
