John Gnadke, DuPont Pioneer harvest management and grain quality consultant, said that although bins may feature automated equipment, grain should be checked first on a weekly and then biweekly basis.
"We cannot take the human situation out of that. It's important that we look into the bin, open the lid, have somebody start the fan and allow the air to come out," Gnadke said.
If humidity is detected in the air exiting the bin, the grain is in cold sweat.
"Temperature tables will not show a temperature rise at that point, but it will be in that cold sweat area. If we can catch it early, we can run fans, and we can avoid any situations," Gnadke said.
He recommends checking the bins once a week for four weeks to monitor the grain's stability and then biweekly thereafter.
"However, don't ever extend the biweekly check because the majority of people who do call say they forgot to do what I said and that turns out to be four, five or maybe even six weeks, and they have some damage in their grain bins," he said.
Gnadke received several inquiries the past two Decembers asking why grain was beginning to re-wet itself.
"In all those cases I ask them how large their bin was, what size fan they have and how many days did they run it, and in most cases they all ran it about half the amount of time it takes to thoroughly cool the grain down," he said.

Opening a bin and examining the grain within it is vital, said John Gnadke, harvest management and grain quality consultant for DuPont Pioneer.
"Check that grain even though we have automated equipment," Gnadke said.
Gnadke said farmers need to open their bins and check the grain. Someone else will need to start the fan and allow the air to come out through the grain.
If the air comes out of the grain with some humidity or stickiness to it, the grain is going through a "cold sweat," Gnadke said. Temperature cables would not be able to catch this change in grain temperature, making the hands-on check that much more important.
In the cold sweat situation, catching it early is a good way to stop it from affecting grain quality, he said. Running bin fans on grain in a cold sweat will lower grain temperatures.
Gnadke said when grain is first stored, check it weekly for the first four to five weeks and then check every two weeks. He recommends not going more than two weeks without checking stored grain, noting that skipping checks only increases the incidence of grain-quality problems.
