NOTE: The US Federal Reserve concludes a two-day meeting, with a statement and news conference expected at 1 p.m. CDT (1800 GMT).
WHEAT - Up 1 to 2 cents per bushel
Modestly higher in rangebound trade as the market awaits fresh direction. Plentiful global supplies and a large Russian harvest offset worries about dry conditions in Australia and excessive rain in Argentina.
Rains expected next week should help recharge soil moisture in the southern US Plains winter wheat belt, where planting is under way.
CBOT December soft red winter wheat last traded up 1-1/2 cents at $4.44-1/2 per bushel, K.C. December hard red winter wheat was up 1-3/4 cents at $4.43-3/4 and MGEX December spring wheat was up 1-3/4 cents at $6.19.
CORN - Steady to up 1 cent per bushel

Ukraine's maize harvest is expected to reach 27 million tonnes this year compared with 28 million tonnes in 2016, the country's first deputy agriculture minister said.
CBOT December corn last traded up 3/4 cent at $3.49 per bushel.
SOYBEANS - Up 3 to 4 cents per bushel
