I couldn’t finish drying my corn with natural air last fall. |

If corn at the top of the bin is wetter than 19%, run the fan continuously until the corn is dry, starting March 1. For 17-19% moisture corn, run the fan continuously starting March 15 until the corn is dry.
For corn less than 17% moisture that is to be dried to 14% or less moisture, run the fan continuously starting about April 1 until the corn is dry. If you are shooting for a final moisture of 15%, turn the fan off when the humidity is less than 50% to avoid overdrying corn in the bottom of the bin.
