CBOT Trends-Wheat, corn down 2-3 cents, soy down 3-4

CHICAGO, March 25 (Reuters) - Following are U.S. expectations for the resumption of grain and soy complex trading at the Chicago Board of Trade at 8:30 a.m. CDT (1330 GMT) on Tuesday.

WHEAT - Down 2 to 3 cents per bushel

Wheat futures ticked down on improved weather forecasts in crucial growing regions, with traders monitoring ongoing Russia-Ukraine peace negotiations.

Forecasts show positive conditions for the Black Sea region and rain expected in the U.S. wheat belt.

The U.S.-Russia talks on Ukraine also weighed on prices, with progress potentially bearish for prices as a ceasefire could secure Black Sea shipments.

The U.S. Department of Agriculture in a weekly crop report on Monday rated 49% of the winter wheat in top producer Kansas as in "good to excellent" condition, up 1 percentage point from the previous week, but ratings fell in Oklahoma as wind-whipped soils lost moisture.

CBOT May soft red winter wheat futures WK25 were last down 2-1/4 cents to $5.46 per bushel. K.C. May hard red winter wheat KWK25 was last down 4-1/2 cents to $5.73-1/2 per bushel, and Minneapolis May spring wheat MWEK25 was last down 3 cents to $5.89-1/4 per bushel.

CORN - Down 2 to 3 cents per bushel

Corn futures fell as traders liquidated long positions ahead of the implementation of new U.S. tariffs and the U.S. Department of Agriculture's March 31 planting surveys, with expectations that farmers will plant more corn.

A strong dollar further pressured prices, making U.S. exports less competitive.

Beneficial rains over Brazil's corn crop have also weighed on prices.

CBOT May corn CK25 was last down 3-1/4 cents to $4.61-1/4 per bushel.

SOYBEANS - Down 3 to 4 cents per bushel

Soybeans futures edged down on declining Chinese demand for U.S. soy amid the China-U.S. trade spat and Brazil's advancing bumper harvest.

CBOT May soybeans SK25 were last down 4-3/4 cents at $10.02-1/2 per bushel.
