Chicago | Reuters — U.S. soybean futures rose on Thursday, rallying from early declines on short-covering and prospects for China to step up purchases of U.S. supplies as the U.S.-China Phase One deal goes into effect in days, traders said.
But wheat and corn futures fell, pressured by a stronger U.S. dollar, worries about economic fallout from the coronavirus outbreak and outlooks for large South American harvests.
The March soybean contract on the Chicago Board of Trade settled up 3-3/4 cents at $8.96-1/4 per bushel to post its ninth consecutive higher close (all figures US$).

CBOT March wheat ended down 3-1/4 cents at $5.44-1/4 per bushel. March corn settled down 3-1/2 cents at $3.79-1/2 a bushel, staying inside Wednesday’s trading range.
Wheat and corn took cues from declines in world equity markets, which were on the defensive as a sharp rise in the death toll from the coronavirus in China stoked concern about its impact.
Corn was also pressured by expectations for large South American harvests, given generally favourable crop weather.
