I can't give you the exact amount. It varies by location time. For the individual producer it can mean a significant amount. I think that's what Grain Growers was getting at.
On a regular basis, grain dryers are used sparingly, but some years, and this would be one, where it was either harvest them with a higher moisture content than ideal or not harvest them at all....
It is cyclical and it is region specific. For that reason, it has a significant impact at various times.
