BEIJING, June 29 (Reuters) - Chicago soybean and corn

futures fell on Monday, while wheat traded almost flat, as

traders adjusted positions ahead of the U.S. Department of

Agriculture's quarterly grain stocks report on Tuesday.

FUNDAMENTALS

* The most-active soybean contract on the Chicago Board of

Trade (CBOT) was down 0.56% at $11.49-3/4 a bushel, as of

0127 GMT, while corn fell 1.02% to $4.37 a bushel. Wheat

was up 0.04% at $5.9 a bushel.

* The U.S. Department of Agriculture is set to release its

soybeans and corn to rise year-on-year, and see farmers planting

about 85.4 million acres of soybeans and 95 million acres of

Hotter-than-normal conditions are expected from the Plains to

the Atlantic Coast through July 4, the National Weather Service

said last week.

and ample global supplies.

2026 second corn area, compared with 19.4% at the same time last

year, Patria Agronegocios said.
