Corn was up 2.6 percent for the week, its ninth increase in 10 weeks.      * U.S. corn sales last week stood at 1.4 million tonnes, well above analysts' expectations that ranged from 525,000 to 725,000 tonnes, according to a report from the U.S. Department of Agriculture.

       * Still, analysts expect a key USDA report, due on Monday, to show that stronger-than-forecast export demand likely cut U.S. soybean supplies to the lowest in 10 years, suggesting end users could run out of supplies before harvest this fall.
