Don’t Walk Away From Grain Bins Now

Don’t Walk Away From Grain Bins Now
Inconsistent grain quality means stored grain should be checked often.

If you're done harvesting by now, great. If you still have a few fields to go, likely they were planted late. You may need to read this information as much as anyone. In fact, you can still help prevent problems in the grain bin by paying attention to the amount of foreign material and broken kernels going into your truck out of the combine hopper. If there is more than there should be, adjust your combine, even if you're binning the grain and not worried right now about dock at the elevator. The grain will keep better if it's of better quality and broken pieces and fines stay pour of the bin.

That's the word from Matt Roberts in northern Indiana. A farmer himself, he is working part-time to assist the Purdue University Extension staff whom advise farmers about grain storage issues. The other grain quality specialist at Purdue who urges farmers to watch stored grain carefully every year, and especially this year, is Richard Stroshine. He is an Extension ag engineer.

Both experts agree that if you have all your corn in the bin, but you haven't pulled out fines yet by coring a bin, and taking out as many loads as it takes for the center of the grain mass to flow out, then you should do it soon. Coring a bin does two things- it pulls out many of the fines and broken matter because that material tends to accumulate in the middle of the bin as corn comes in, and it levels off the peak of grain at the top of the bin that formed as you finished filling the bin.

Both removing fines and leveling the peak help improve aeration, or air flow up through the corn. If you dumped grain hot at 17% moisture into a bin, hopefully it was an aeration bin equipped with a fan that can deliver at least 1.0 cubic feet per minute of air flow. When you aerate, the drying front will move up through the grain. The denser core of fine materials in the center or a peak of grain at the top, or both, impede consistent flow of the drying front through the grain mass. Your first goal should be making sure that air can move freely up through the mass to accomplish drying and cooling.
