Situation: I have a 27-foot diameter bin 18 feet to the eave. It has a full mesh floor but only a 5 HP aeration fan. I will need to dry corn in this bin this year.
The time required to dry grain in a bin is a function of the initial moisture content of the grain, the desired final moisture content of the grain, the temperature and relative humidity of the air passing through the grain and the rate of airflow through the grain (cubic feet per minute per bushel: cfm/bu).

Learn how to get an edge on managing Palmer amaranth resistant to atrazine and HPPD-inhibitor herbicides Tuesday, Aug. 4 at a Nebraska Extension field day near Shickley.
