Breaking News-RTRS-USDA's corn, soy crop forecasts to rise-Hightower

CHICAGO, Aug 5 (Reuters) - The U.S. Department of Agriculture is likely to raise its estimate of the U.S. 2008 corn crop in its August supply/demand report next week, reflecting improved crop prospects, commodity analyst David Hightower of The Hightower Report said on Tuesday.

For soybeans, USDA might not raise its yield estimate next week, but an increase in planted acreage should help lift the government's 2008 soy production estimate.
