BUENOS AIRES (Dow Jones)--Argentine soy prices followed the Chicago Board of
Trade lower on the week, with light trade as farmers hold out for a rebound.

  Supportive weather in the U.S. boosted crop prospects, driving down
international soy prices, the Rosario Grain Exchange said.

  Spot soybeans were traded at between ARS885 ($228) and ARS915 a ton in
Rosario, down from between ARS910 and ARS940 a week ago.

  May 2010 soy futures traded at $214 and $216 a ton, up from $213 a week ago.

   Corn


  Spot corn was traded at ARS390 a ton Thursday in very light trade as farmers
wait in hope for the higher prices agreed with the government.

  On Thursday, the government's theoretical price that farmers should receive
for spot corn was set at ARS463 per ton. That theoretical Free-Alongside-Ship
price is the Free-On-Board price minus export taxes.

  Corn trade has stalled since June 16 as exporters are hesitant to buy at the
government's set price and most farmers refuse to sell at a lower price.

  On June 16, Argentina's grain exporters reached a deal with the government to
buy up to three million metric tons of 2009-10 corn and an additional one
million tons of new crop wheat at a theoretical price set by the government. In
exchange, the exporters will be ensured export permits for the surplus wheat
and corn from the 2009-10 crop.

  The deal is designed to boost local corn prices, which have been trading at a
discount due to a risk premium because of the government's intermittent closing
of exports.

  The government hopes the new agreement will stimulate wheat and corn planting
this season amid signs that the area planted with the crops will fall sharply
as farmers continue a major shift to soybeans.

   Wheat


  December wheat was traded at $145 a ton Thursday.

  Spot wheat was last traded at ARS654 on June 18. The government's theoretical
FAS price on Thursday was ARS656 per ton.
