CHICAGO, Jan 22 (Reuters) - Chicago Board of Trade corn futures ticked up on a falling U.S. dollar, as well as weather concerns in Argentina.
CBOT March corn CH26 settled up 2-1/4 cents at $4.24 per bushel.
Dry conditions were building in parts of Argentina's crop belt with warm temperatures expected this weekend, the Commodity Weather Group said in a client note.
Argentina's 2025/26 corn production estimate rose 6% to 57.9 million metric tons on larger-than-expected planting area, LSEG said in a report on Thursday, but low rainfall and declining soil moisture could limit yields, especially for for late-planted corn.
A softer dollar tends to make U.S. exports more competive to holders of other currencies.
