The process is known as evapotranspiration, which is how plants, including corn, release water vapor into the atmosphere.

A heat wave will hit Michigan later in the week and the state's corn fields will amplify the extreme temperatures.

It is “corn sweat” season. The biggest U.S. crop does influence our weather here in Michigan and across the Midwest. All plants drink up moisture from the soil and then breathe some of it out in a process called transpiration. The transpiration puts water vapor in the air and increases the humidity.
