do ags have a "slow period"?

I'm new to trading ags, so I was just wondering if there are any time periods of the year where ags are in a quiet or slow period? I have traded corn or soy, but if there are slow periods, then do they extend for the other ags like wheat, etc?

 

Yes. At night.

Just kidding, but I had to say that when I saw the title.

 

When there are "bumper" crops, the Fall and late Winter tend to be "slow". It may be a long time before that occurs again.
