US soyabean futures fell on Tuesday, setting back from their highest since December 7 on dry weather in South America that will allow farmers to accelerate the harvest of what is expected to be a huge crop, traders said. Wheat futures also closed lower, with traders reporting mild profit taking following the market's run-up to a 5-1/2-week high on Monday, traders said.
Corn futures were close to unchanged.
"The support we have been getting has been from fund buying and short covering," said Karl Setzer, market analyst with MaxYield Cooperative. "We just ran out of steam with that. There is just no reason to buy today. All in all, (it was) just kind of a risk-off type day."
The US Agriculture Department's reports on crop conditions in the US Plains added pressure to the wheat market but forecasts for some dry weather in the coming weeks limited the declines.
"Better conditions and weather concerns push and pull on the market," CHS Hedging said in a note to clients.
