Agricultural commodities got off to a mixed start to the week as fundamentals took a back seat in favour of squaring positions ahead of Tuesday's key crops report.
The signals from external markets were generally negative, with oil and shares sliding and the dollar strengthening.
Still, Chicago soybeans and wheat gained ground in electronic trading, although corn edged lower, as the prospect of the latest official report on US crop plantings dominated trade.
The US Department of Agriculture report, which will update statistics published in March, is expected to indicate a switch by farmers from corn, where plantings were delayed by rain, into soybeans, which can be sown later and, besides, have been enjoying buoyant prices.
"There's just last minute squaring ahead of the report," Toby Hassall, an analyst at Commodity Warrants Australia, told Reuters, the news agency.
In addition, Tuesday will provide the first-day delivery notices for Chicago's July grain and oilseed contracts, marking the start of the occasionally momentous period of the lots' closures.
July soybeans were 5 cents higher at $12.06 a bushel at 06:15 GMT, with wheat up 3.25 cents at 5.37 ½ a bushel. Corn was 1.75 cents lower at $3.82 ½ a bushel.
Meanwhile, in Kuala Lumpur, palm oil lost 2% in the morning session as longstanding concerns of a rise in production mixed with new ones over India's potential imposition of an import tax.

"There is lots of uncertainty in the market about the Indian import taxes," a trader said.
