Nearby corn backed off the trading limit after an afternoon pullback to close higher, replying mostly to bullish USDA grain stocks reports released Thursday morning.

At the close, July corn futures were 21 1/2 cents higher at $7.85 1/2 per bushel while July soybeans ended the day 7 3/4 cents lower at $13.93 3/4 per bushel, reflecting USDA's bean stocks numbers higher than estimates a month ago. July wheat futures ended the day 3 cents lower at $7.45 per bushel, according to Barchart.com.

Weather extremes in corn country could make for a lot of squirming in the near future," says Agriculture.com Marketing Talk member Palouser. "I don't see a way out of this unless the corn belt becomes the Garden of Eden the rest of the summer. I have never been so uncomfortable about grains."
