If you're going to market your corn this winter as many people often do, say in January or February, then Klein Ileleji says you should dry it to 15% as it goes into final storage. Ileleji is the Purdue University Extension grain specialist.

However, if you are intending to hold out for higher prices and wait until the market glut fades, or at least if that is your strategy, then you may need to get it drier before you put it in final storage. He recommends drying it to 14% if you think you may hold it an entire year.

Set for long term: If these bins were going to hold corn for a year or longer, you would want the moisture content at 14% or below as the storage cycle begins.

Some people who had corn still in the bin over the past few weeks earned a premium when ethanol plants needed corn. However, with the larger carryover expected form this year's harvest, there is no guarantee that will provide a premium next year during the gap between old corn and 2015 corn.

If you're really bearish and think you may have to keep corn in your bin more than a year for marketing purposes, then you need to make sure it is even drier before you put it into final storage, the specialist says. He recommends below 14% all the way down to 13% if you think you will want to hold it more than a year. Part of the reason for dropping moisture lower is to increase the odds that molds and insects won't have an opportunity to grow inside the bin in corn that is held for longer term storage.

Even if you are just holding corn for delivery in January or February, make sure the corn is truly at the moisture level you think it is before you quit aerating or drying. Double check moisture readings and be sure you're compensating for temperature of the grain if your moisture meter doesn't do it automatically.
