* Rains in Argentina expected to bolster corn, soy crops

CHICAGO, Jan 2 (Reuters) - U.S. soybeans fell to a one-month
low on Thursday on a mix of technical selling, prospects for
large South American crops and weakness in soymeal values,
Corn firmed on short covering and spreading against soybeans
but wheat sagged under the weight of plentiful global supplies,
with values on the Chicago Board of Trade setting
At the CBOT as of 11:02 a.m. CST (1702 GMT), most-active
March soybeans were down 19 cents at $12.73-1/2 per
March corn was up 1-1/4 cents at $4.23-1/4 a bushel
and March wheat was down 8-1/2 cents at $5.96-3/4 a
Soybeans declined as rains fell in parts of Argentina, where
soy and corn crops have been in need of moisture. In Brazil, the
harvest of a likely record-large soybean crop is under way in a
"Argentina overnight and early this morning had some very
timely showers, and that is the thing pressing the soybean
market. They are taking the weather premium out," said Don
Roose, president of U.S. Commodities.
Argentina will need more rain in the coming weeks, said Joel
Widenor, a meteorologist with the Commodity Weather Group.
"There was at least three-quarters of the Argentine corn/soy
(region) that picked up mostly 0.5 to 1.5 inch (1.3 to 3.8 cm)
in the past week. This was enough to limit concern to less than
one-quarter of the corn for the near-term, but more rain is
needed at mid-month," Widenor told the Reuters Global Ags Forum.
"Most of the concern this month will be for corn
pollination. Soy will not reach key stages until February,"
Also, commodity funds are net short in corn and net long in
soybeans, and Roose said they appeared to be unwinding long
corn/short soybean spread positions as the new year begins.
CBOT corn fell 40 percent in 2013, the biggest loser among
major commodities, while soybeans fell 7.5 percent on the year.
Soymeal futures fell the most by percentage on Thursday in
the CBOT soy complex on worries of a slowdown in demand, given a
sharp fall in prices for dried distillers' grains (DDGs), a
competing feed ingredient made from corn.
U.S. cash prices for DDGs have tumbled in the last two weeks
since China rejected some cargoes of U.S. DDGs due to an
unapproved genetically modified strain of corn.
Traders are concerned that a drop in Chinese demand for DDGs
will cause a backlog of U.S. supplies, further depressing prices
and threatening to replace soymeal in feed rations.
"I think the trade is surprised at how hard DDG prices have
fallen and how delicious DDGs look compared to soymeal," said
Rich Nelson, analyst with Allendale Inc.
CBOT wheat fell to contract lows below $6 a bushel, with the
front month falling to a 19-month bottom, on ample global wheat
supplies and a lack of export demand.
"When are we going to find buyers? That's the main
question," Nelson said.
CBOT wheat lost 22 percent in 2013, its biggest annual loss
in five years.
A cold snap is forecast for the central United States early
next week, with temperatures dropping below zero degrees F
(minus 18 Celsius), but the threat of winterkill should be
limited to hard red winter crops in parts of northern Kansas and
eastern Nebraska, forecasters said.
The core of the cold on Monday and Tuesday will be in the
Midwest, but a thick blanket of insulating snow should protect
the dormant soft red winter wheat crop there.
