GRAINS-Wheat falls on favorable weather in growing regions

By Renee Hickman

CHICAGO, Aug 27 (Reuters) - Chicago wheat futures lost ground on Wednesday, with prices weighed down by large global harvests, favorable weather in growing areas and a strong U.S. dollar, analysts said.

Corn futures followed wheat down and soybeans ticked slightly lower on growing optimism about U.S.-China trade negotiations but a large crop was still expected.

The most-active corn contract on the Chicago Board of Trade (CBOT) December corn CZ25 fell 3-1/4 cents to $4.06-1/4 a bushel as of 12:19 p.m. (1719 GMT), December wheat 25> lost 7 cents to $5.24-3/4 a bushel and November soybeans SX25 were down 2 cents at $10.47-1/2 a bushel.

K.C. winter wheat KWv1 also fell to contract lows.

Wheat is falling amid forecasts for rainfall in winter wheat-growing areas in the coming days. "That will go a long way with restoring soil moisture and preparing winter wheat seed beds," said Brian Hoops, president of Midwest Market Solutions.

Meanwhile, high corn prices have dampened export demand, according to Terry Linn of Linn & Associates.

U.S. farmers are on track to harvest the nation's biggest corn crop in history this autumn, as well as a bumper soybean crop.

However, the soybean market is shifting its focus to probable U.S.-China talks this week.

Senior Chinese trade negotiator Li Chenggang is expected to travel to Washington this week to meet U.S. officials, a United States government spokesperson said, with the two superpowers looking to chart a path beyond their current tariff truce.

"These yet-to-be-determined supply and demand outcomes each have the potential to sway our domestic carryout from an extremely bearish to an extremely bullish end result," said Linn.
