* Tight stocks give extra boost to soybeans

CHICAGO, May 28 Chicago Board of Trade (CBOT)
corn and soybean futures rallied on Tuesday with soy leaping
more than 2 percent, the most in two weeks, as wet U.S. weather
threatened to trim crop acreage and yields.
New-crop December corn futures, the corn contract most
affected by planting delays, rose 2.7 percent, the biggest gain
for that contract in a month and the fourth consecutive trading
session in which it has climbed.
"There was more rain than expected and more is coming this
week. There is concern we'll lose more corn acres than
previously thought and now it's delaying soybean plantings too,"
said Art Liming, a futures strategist for Citigroup.
Tightness in stockpiles of each also lent support and soy
garnered extra strength from another sale of U.S. soybeans to
China, the world's top buyer of the legume.
Wheat turned lower as wetter U.S. weather was viewed as
favorable to the growing winter wheat crop, thus bearish for
CBOT July-delivery corn closed up 9-1/4 cents at
$6.66-1/2 per bushel and new-crop December ended 14-1/2
higher at $5.51.
Soybeans for July delivery were up 33 at $15.09-1/4
and new-crop November rose 40-1/4 to $12.88.
"We're adding some risk premium to the market so the bottom
line is there is a risk-on mentality," said Don Roose, president
of U.S. Commodities in Des Moines, Iowa.
The jump followed wet weekend weather as trading resumed
after a three-day holiday break in the United States and in the
run-up to a weekly crop update from the government due after the
close in Chicago that will detail U.S. corn and soybean planting
progress for the latest week.
A Reuters survey of 11 analysts pegged U.S. corn plantings
at 86 percent complete, behind the 95 percent five-year average
and soybean plantings were estimated at 42 percent complete, the
slowest pace in 17 years.
"It's all weather, due to wetness in Iowa and west-central
Illinois. People are trying to understand what it means to
planted acreage," said Dan Basse, president of AgResource.
The rainy conditions have turned attention back to crop
risks linked to relatively slow planting so far this year.
Rain over the weekend and this week will drag out late-
season plantings of corn and soybeans in the United States that
are already at a historically slow pace, an agricultural
meteorologist said on Tuesday.
John Dee, a meteorologist for Global Weather Monitoring,
said 1.0 to 3.0 inches (2.5 cm to 7.6 cm) or more of rain fell
over the weekend in the central Midwest, and 0.5 inch to 1.5
inches is expected at midweek in the northern Midwest.
"The only planting that will take place will be in the
southern two-thirds of Illinois, Indiana and Ohio the next
couple of days," he said. "If it were all planted this would be
perfect, there was pretty good planting progress last week, but
not like the week before."
Farmers have been scrambling to plant corn and soybeans
through mid- and late May to catch up after weather delays in
April and early May.
Corn planted after mid-May typically has lower yields due to
The wheat market was more subdued but garnered some
underpinning from the strong gains in corn and soybeans.
"There wasn't much in wheat. There were some rains in Kansas
but Oklahoma missed out, so now we're waiting for harvest to see
how much wheat was lost to drought and freezes," Liming said.
CBOT July wheat was down 3-3/4 cents at $6.93-3/4 a
November milling wheat in Paris was up 0.75 euro at
204.75 euros per tonne. It had fallen on Monday as the European
market focused on the outlook for Black Sea wheat and shrugged
off the wet U.S. weather.
