CHICAGO: U.S. soybean futures touched a one-month high on Tuesday on concerns about the risk of U.S. supplies tightening and unfavorable weather hurting yields, analysts said.

Wheat and corn futures also advanced as Ukrainian officials said Russian air strikes damaged infrastructure at the Black Sea port of Odesa, a day after Moscow quit the export deal that facilitated Ukraine crop shipments.

Money flowing into the markets helped boost futures, said Arlan Suderman, chief commodities economist for broker StoneX.

"Soybeans are doing some impressive things on the charts because of their tight stocks situation, and corn and wheat are following along," he said.

Most-active soybean futures finished 17-1/4 cents higher at $13.95-1/4 a bushel at the Chicago Board of Trade and reached their highest price since June 16.

CBOT wheat settled up 17 cents at $6.70-3/4 per bushel, while corn climbed 28-1/2 cents to $5.34-1/2 a bushel and set its highest price since June 29.

The U.S. government has said farmers cut back on soybean plantings this year to devote more acres to corn, though federal forecasters still expect large harvests of both crops.

Traders are worried about the potential for warmer, drier weather to trim yields in late July and in August, which is the critical month for soybean development.

"You could just set the crop up for a bit of poor finish," said Matt Wiegand, commodity broker for FuturesOne. "Especially on soybeans, there's just not a lot of room to take a lot off the top."

In the Black Sea region, there are a "number of ideas being floated" to help ship Ukrainian and Russian crops and fertilizer after Moscow quit the grain export initiative, the United Nations said.

CBOT corn and wheat futures closed lower following Russia's exit on Monday.

"Yesterday's market showed the market really doesn't care about the grain initiative right now," Suderman said. "Maybe it will in the future."
