CANBERRA, Aug 3 (Reuters) - U.S. corn futures fell on Tuesday amid a broad commodity sell-off on concerns over the global economy, though losses were limited by a widely watched report that showed the condition of U.S. crops was worse than expected.

FUNDAMENTALS

* The most active corn futures on the Chicago Board Of Trade were down 1% to $5.54 a bushel by 0121 GMT, having gained 2.6% in the previous session when prices hit a July 27 high of $5.59-3/4 a bushel.
