What follows are opening calls for U.S. grain and oilseed markets. -- Soybean futures may open 1 cent to 3 cents a bushel higher on the Chicago Board of Trade on increased U.S. export sales, Mark Schultz, the chief analyst for Minneapolis-based Northstar Commodity Investment Co., said in a telephone interview. Soybean-meal futures may open up $1 to $2 for 2,000 pounds, and soybean-oil futures are expected to open steady to down 0.1 cent a pound. -- Corn futures are called to open 2 cents to 5 cents a bushel lower in Chicago as rain in Iowa and Nebraska, two of the three biggest U.S. producers, may ease the risk of crop damage from a heat wave, while forecasts show less-threatening conditions in parts of the Midwest during the next two weeks, Schultz said. -- Wheat futures may open 1 cent a bushel lower to 1 cent higher on the CBOT, the Kansas City Board of Trade and the Minneapolis Grain Exchange as a weaker dollar reduces the cost of supplies from the U.S., which today reported exports last week were 36 percent below the average of the previous four weeks, Schultz said.
