    PARIS/SINGAPORE, March 12 (Reuters) - Chicago wheat futures extended losses
on Friday to a one-month low as rain forecast for dry parts of the U.S. Plains
eased supply concerns.
    Soybean edged lower as it moved back from a near seven-year high this week,
with the market weighing increased estimates of Brazil's soybean harvest against
a declining outlook for Argentina.
    Corn also eased, with traders awaiting indications about U.S. spring
planting trends and fresh signs of Chinese demand.
    The most-active wheat contract on the Chicago Board Of Trade (CBOT)
was down 0.4% at $6.40-1/4 a bushel by 1026 GMT, after earlier touching its
lowest since Feb. 12 at $6.38.
    "The upcoming rainfall to the U.S. Hard Red Winter wheat regions, including
the very western third, continues to weigh on prices," Tobin Gorey, director of
agricultural strategy at the Commonwealth Bank of Australia in Sydney, said.
    Significant rain expected in the coming days in a swathe of the U.S. Plains
could bring relief for parched crops as they enter the key spring growth phase.
    The improved moisture outlook for U.S. wheat coincides with reports of
better growing conditions in top exporter Russia, along with a favourable
situation in the European Union. 
    An import tender by Egypt on Thursday also tempered supply concerns, as it
showed a large number of offers, including bids of Russian wheat despite a
recent export tax.
    Egyptian state buyer purchased 360,000 tonnes of Romanian wheat in the
    CBOT soybeans were down 0.3% at $14.08-3/4 a bushel, on course for their
first weekly loss in five.
    CBOT corn was down 1.0%.
    The Buenos Aires Grains Exchange lowered its estimates of Argentina's
soybean harvest to 44 million tonnes and its corn forecast to 45 million tonnes,
below its previous forecasts of 46 million tonnes for each crop, citing dry
    But several forecasters have increased estimates for Brazil's ongoing
soybean harvest, despite rain delays.
    Concern that renewed outbreaks of African swine fever in China could weaken
demand for livestock feed like soy has weighed on the market, countering support
from a global rally in vegetable oils including soyoil.
