CHICAGO--U.S. corn and soybeans futures were lower Monday as weather forecasts improved after weeks of steady rain.

Soybean prices led the declines as forecasts for drier weather in July promised to help dry soggy Midwestern fields, providing relief for crops after persistent rains drenched fields and delayed soybean seeding.

Still, analysts expect a weekly government report to show row crop conditions deteriorated last week compared to a week earlier, adding to uncertainty over the size and health of this year's corn and soybean crops.

Soybean futures for July delivery sank 11 1/2 cents, or 1.1%, to $10.33 3/4 a bushel at the Chicago Board of Trade.

A stronger U.S. dollar also weighed on prices for agricultural commodities, analysts said.

Corn prices eased as the market absorbed an uptick in selling by farmers, who last week marketed their crops in order to take advantage of higher prices. Traders and investors are mostly waiting for a monthly supply-and-demand report, due Friday, to provide further information on yield prospects, analysts said.

CBOT July corn declined 1 1/4 cents, or 0.3%, to $4.18 1/2 a bushel.

Wheat prices gained amid ongoing concerns over the quality of soft-red winter wheat, which is grown in the eastern U.S. and suffered from excess moisture in June.

CBOT July wheat gained 2 3/4 cents, or 0.5%, to $5.88 1/2 a bushel.
