Heat and humidity are back in full force this week as the peak of summer comes to an end. This combo can spell out hazardous conditions especially for those outside for a prolonged time. Farmers that are out in the field can face extra risks, not just from time outdoors, but from the crops themselves as well.
Those with an agriculture background may be familiar with "corn sweat" which describes how corn fields can produce extreme humidity during the summer. This is due to the moisture evaporating from the plant's leaves, which is released as water vapor that is concentrated around the field. This added moisture can increase the temperature by 5 to 10 degrees locally, though the effects aren't felt too far out of the cornfield. Drought may also help mitigate this process somewhat, as corn stalks will roll up their leaves to conserve water and reduce evaporation in dry conditions.
