Crops and humidity

MASON CITY, Iowa – Things are drying out quickly, but on Monday and Tuesday, there was no mistaking the humidity in the air. Mother Nature isn’t the only one to blame though.Crops, especially corn, contribute to the steamy conditions.

According to the National Weather Service, when corn crops are mature, they can pump 54 billion gallons of water into the atmosphere each day. That can add five to ten degrees to the dew point on hot days like today.

“It’s the trans-evaporation that goes on between the soil and the plant. It sucks up moisture out of the ground because it needs it. It (the moisture) moves through the plant, moving nutrients through that plant, and then the water leaves the plant as well and goes into the air,” says Iowa State Extension Office Director John Sjolinder.

The good news is he says, Tuesday’s weather was perfect for growing and exactly what crops needed to catch up from the wet and cooler weather earlier this season.
