U.S. Grain-, Soybean-Inventory Forecasts to Be Cut, Survey Shows By Jeff Wilson
March 5 (Bloomberg) -- U.S. corn, wheat and soybean inventories before the 2012 harvests probably will be smaller than the government forecast last month as hot, dry weather damages crops in South America, boosting demand for U.S.
exports, according to a survey of as many as 28 analysts by Bloomberg News.
The U.S. Department of Agriculture is scheduled to update its reserve estimates at 8:30 a.m. on March 9 in Washington.
Figures in the following tables are in millions of bushels.
