John Gnadke, ..., 10 Jan 2014 [cached]
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.

Don't skimp on the site The construction of a concrete foundation might require an extra $500 or $1 , 000 of steel or concrete , says John Gnadke , president of AGS Incorporated , an Ankeny , IA , storage consulting firm.But that's inexpensive when you amortize it out over 30 years.The site should be built with a long-range plan to meet the challenges of tomorrow..
Install fully perforated bin floors By moving the grain off concrete , moisture won't seep into the corn , Gnadke says.If moisture ends up in the grain , you'll not only spoil grain , but also encourage the resident bug population.When the grain is above the ground , it's so much easier to control its moisture..
Buy a dryer with low temperature swings To ensure optimum quality , dryers should have just a 5- to 10-degree temperature variance , Gnadke says.
High-quality grain cannot tolerate the 30- to 50-degree swings during drying , he adds.Excessive heat that spurs stress cracks in corn can ultimately dissolve premiums for high-value grains.
Install a storage system with easy clean-out Identity preservation makes this quality paramount.

Like the saying goes-if it was easy money then everyone would want to do it, notes John Gnadke, a quality grains specialist with AGS, Inc., Ankeny, Iowa.
"Before jumping into a specialty crop market a producer really needs to make a list of positives and negatives regarding various value-added production opportunities," says Gnadke."Location, equipment, facilities, management style and flexibility are all part of the value-added equation."
As a former pilot, Gnadke compares today's specialty grains market to flying.
"Flying a plane is serious business.One little mistake can cost you your life," says Gnadke.
According to Gnadke, worn parts such as thin augers, loose chains and out-of-round concaves all add up to losses in quality.
That's why Gnadke suggests to stop unloading before running a grain tank empty-the result: an overall improvement in deliverable quality.
Gnadke says that new combines are greatly improved in terms of their quality performance compared to their older model predecessors.However, it is beyond the combine where many producers fall short of the quality bar.
"Through the years as farms have gotten larger, producers have expanded and upgraded their machinery but their grain handling system is basically the same as it was a generation ago," notes Gnadke.
Gnadke says more growers need to look at simpler, more economical systems such as smaller bins with a belt conveyor as the main means of transferring a crop.
Gnadke suggests newcomers to the value-added business start with a maximum of 10 to 20 percent of total acreage committed to premium contracts the first year.After that you can build on your successes.Once you have the experience, the tools and the facilities in the specialty arena, it becomes much easier to grab on to new opportunities.
"The key to success in the value-added business is being able to substitute the emphasis on production to an emphasis on professionalism," says Gnadke.
