CBOT Trends-Wheat up 1-3 cents, corn and soybeans mixed

CHICAGO, March 18 (Reuters) - The 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 Wednesday:

WHEAT - Up 1 to 3 cents per bushel

• Wheat futures were firmer on concern about dry conditions in the U.S. Plains winter wheat belt. Gains were limited by weak export demand as cheaper supplies are available from other countries.

• In an annual farmer survey, commodity brokerage Allendale Inc on Wednesday projected all U.S. wheat plantings at 44.877 million acres in 2026, down from 45.3 million last year.

• CBOT May soft red winter wheat WK26 was last up 2-3/4 cents at $5.92-1/2 per bushel. K.C. May hard red winter wheat KWK26 was last up 3-1/2 cents at $6.10-1/4 a bushel and Minneapolis May spring wheat MWEK26 was up 3-1/2 cents at $6.27-3/4 per bushel.

CORN - Up 1 cent to down 1 cent per bushel

• Corn futures were narrowly mixed. Firmer crude oil prices CLc1 underpinned the market, given corn's role as a feedstock for ethanol.

• In an annual farmer survey, commodity brokerage Allendale Inc said it expects U.S. farmers to reduce corn plantings by 5.2% this year.

• CBOT May corn CK26 was last up 3/4 cent at $4.54-3/4 per bushel.

SOYBEANS - Up 3 cents to down 3 cents per bushel

• Soybean futures mixed. Old-crop contracts were pressured by concerns about near-term purchases by China. Expectations for improving demand from biofuels producers underpinned the market.

• U.S. President Donald Trump on Tuesday said he and Chinese President Xi Jinping would delay a meeting that was planned for March 31-April 2, and that it will instead take place in around five or six weeks.

• Trump invited farmers and biofuel producers to an agriculture event at the White House next week, though it is unclear whether the event will coincide with the final biofuel blending rule being released.

• In an annual farmer survey, commodity brokerage Allendale Inc said it expects U.S. farmers to increase soybean plantings by 5.5% this year.

• Brazil's agriculture minister said the government will negotiate soybean inspection and safety requirements for Brazilian shipments to China, following complaints from Beijing.

• CBOT May soybeans SK26 were last down 2-1/4 cents at $11.54-3/4 per bushel.
