* Chicago corn falls after strong gains, soybeans haven’t changed much
* Concerns about dry weather in South America support prices (Add asset details, update prices)
SINGAPORE, Jan 7 (Reuters) – Chicago corn slipped Thursday as the market breathed after hitting a record high of more than six years in the previous session, although losses were limited as dry growing conditions in South America disrupted global supply.
Wheat lost ground for a second session.
The most active corn contract on the Chicago Board of Trade (CBOT) lost 0.3% to $ 4.93-3 / 4 per bushel before 0314 GMT, after gaining 0.7% in the previous session when prices hit a May 2014 high of $ 5.02-3 / 4 a bushel.
Flat soybean futures were at $ 13.61-1 / 2 per bushel and wheat rose 0.2% to $ 6.46-1 / 2 per bushel.
Dry weather continues to threaten soybean and corn production opportunities in Argentina, and labor issues in the South American country have added to supply concerns.
The union representing Argentine port-side grain inspectors was to meet on Wednesday with agro-export companies to try to end a wage deal to end a strike that began on December 9 .
Traders have begun to change their positions ahead of the next U.S. Department of Agriculture monthly supply / demand report on Jan. 12, in which the government releases updated estimates of U.S. and South American crop production and consumption.
Commodity funds were net buyers of CBOT corn, soybean, soymeal and soyoil revenue contracts on Wednesday and net sellers of wheat times, traders said. (Reporting by Naveen Thukral; Editing by Shailesh Kuber)
