This is going to sound really silly, but here goes...

Since I haven't gotten as far in my projects as I would like, this year we again allowed our back field to be used by a somewhat local farmer. He planted corn, which is now close to mature. I wasn't here when he planted, and have no way to contact him, so I have no idea what kind of corn it is.

How do you tell the difference between sweet or edible corn and feed corn?

I know this is from farming 101, but I never had that experience.
