"So how do you decide when to begin harvesting corn?" asks a farmer in Crop Talk. "Does it make sense to shell it at 25% on September 1 or wait till October 1 when we are more often than not beginning harvest and it may be 15%," he adds.

"A lot to consider: weather, stalk rot, LP prices, etc. There's no right or wrong answer until after the fact, of course, but I'm curious how you make the decision to hit it."

Several farmers chime in with their own views. Says one corn grower: "Depends on your own conditions, of course, but for me that's an easy decision--25% corn will make me more money, although I'd rather stay in the 18-22% range."
