Guess what? The old “turn the fans on and leave them on” at harvest isn’t necessarily true. Contrary to what farmers have been told and have been doing for quite some time, warm days actually add or maintain moisture levels in grain bins. Yes, really.

Research on the subject out of the Indian Head Agricultural Research Foundation was, at first, a head-scratcher for the researchers. Shouldn’t warm air with a decent relative humidity be taking water out of the grain and the bin and exhausting out the top? As it turns out, as the temperature difference between air temp and grain temp changes (as in, the grain cools), it actually makes the most sense to flip on the air at NIGHT only, as the outside temp falls.

In this video, Ron Palmer explains the research set up at Indian Head, the findings year over year and how and why this is the case. You don’t want to miss this.
