* Weekly U.S. crop data supports good harvest outlook
* Dollar rebounds as financial markets steady after selloff
* Corn, wheat and soybeans near four-year lows

By Gus Trompiz and Naveen Thukral
       PARIS/SINGAPORE, Aug 6 (Reuters) - Chicago corn, wheat
and soybean futures fell on Tuesday as weekly U.S. crop data
underscored good harvest prospects while grain prices were also
curbed by a stronger dollar as financial markets recovered from
the previous day's slide.
    The most active soybean contract on the Chicago Board of
Trade (CBOT) was down 1.7% at $10.23-1/2 a bushel by 1137
GMT, halting a two-session bounce.
    CBOT corn fell 0.7% to $4.04 a bushel and CBOT wheat
 eased by 0.6% to $5.36-1/2 a bushel.
    All three remain near their lowest in almost four years.
    Grains mostly held up during the selloff in other markets on
Monday as funds covered already large short positions in grains
while an export-friendly drop in the dollar also lent support,
traders said.
    "Price pressure is coming from yesterday's publication by
the U.S. Department of Agriculture on the current crop status,"
Commerzbank said in a note. "Prices are thus still within
striking distance of the multi-year lows recorded last week."
    The USDA's weekly crop report released after Monday's market
close shifted attention back towards favourable production
prospects.
    The report showed the rating for the U.S. soybean crop had 
improved unexpectedly while corn conditions fell slightly, in
line with market estimates. The scores for both crops remained
at their highest for the time of year since 2020.
    The data suggested a limited impact so far from dry, hot
spells in U.S. crop belts and moderate heat forecast in the week
ahead was tempering concern about low moisture in some areas.
    Coupled with large harvests in Brazil, good U.S. growing
conditions have improved the supply outlook for corn and
soybeans, though drought gripping Ukraine and the rest of the
Black Sea zone could dent another major source of corn.
    The USDA crop report also confirmed good U.S. wheat
conditions. Along with a large harvest in Russia, that has taken
the focus away from a poor crop in France.
    In Argentina, rains fell over the weekend in much of the
central agricultural zone, offering relief for wheat crops after
a very dry July.
