CBOT wheat closed 3-4 cents lower and corn was about a penny weaker across the board after several months made contract lows. Reface Fiat Futures and Man Financial were the featured sellers in rice.
Firms were also rolling their March positions before first notice day on February 28.
Estimated volume was light at 276 futures and 48 options. That compared to 761 futures traded on Tuesday.
