WHEAT - Down 8 to 9 cents per bushel

• CBOT wheat futures fell for a third straight session on Tuesday, as the risk of crop-damaging weather ahead of the northern hemisphere harvest receded, reinforcing expectations of a well-supplied market.

• Recent days have seen rain in dry parts of northern Europe, rainfall forecasts in drought-hit cropping regions in China, an upward revision to a wheat yield forecast in the European Union and an upgraded production estimate for Russia.

• Traders were awaiting the U.S. Department of Agriculture's weekly crop report later on Tuesday to see if U.S. winter wheat conditions continued to improve last week.

• Export demand for wheat remains tepid and export prices in top shipper Russia dipped last week.

• CBOT July soft red winter wheat WN25 was last down 9-1/2 cents to $5.33 per bushel. K.C. July hard red winter wheat KWN25 was last down 11-1/4 cents to $5.27-1/2 a bushel. Minneapolis July spring wheat MWEN25 was last down 6 cents to $6.00-1/2 a bushel.

CORN - Down 1 to 2 cents per bushel

• Corn futures lowered, curbed by a bounce in the dollar.

• The U.S. Department of Agriculture in its weekly crop report Tuesday afternoon will release corn condition ratings and planting progress.

• A lack of weather risks to the U.S. corn crop have weighed on prices.

• CBOT July corn CN25 was last down 3/4 cent to $4.58-3/4 per bushel.

SOYBEANS - Up 5 to 6 cents per bushel

• Soybeans rose under support from soyoil futures, which have rallied on hopes that the U.S. Environmental Protection Agency will release new biofuel blending mandates.
