Link between corn and high humidity

A recent article published by MPR talks about the connection between row crops like corn and soybeans and high humidity.  

...because so much of the state is cropland and those plants sweat so much, his research shows more than 60 percent of that local moisture comes from farm fields...

The amount of moisture they talk about is staggering and according to the article, (row crops) can add 5 to 10 degrees to the dew point on a hot, summer day.

This is one more reason we avoid / reduce row crops like corn and soy, organic or otherwise.
