The short-covering which surprised many grain and oilseed investors by failing to turn up in the last session wasn't much in evidence in this one either.
Today brings the US Department of Agriculture's influential monthly Wasde crop report, which is expected to upgrade the estimate for domestic corn inventories at the close of 2013-14, implying weaker price prospects, but raise the forecast for soybean stocks.
But will it? Uncertainty ahead of the report, part of a series which often brings large swings in crop prices, brought higher prices on Thursday as investors booked profits on short positions.
This effect reversed in the last session, and was around, generally, in only a weak guise on Monday too.
The exception was soybeans, which did manage a decent start, adding 0.5% to $11.88 a bushel in Chicago as of 09:30 UK time (03:30 Chicago time) for November delivery.
There is, of course, the issue of the potential cut by the USDA in its estimate for US stocks, with analysts expecting a downgrade of 32m bushels to 263m bushels, according to a Bloomberg survey.
Thinner stocks imply higher prices, with buyers forced to compete more for supplies.
But there are some other issues too, with talk of further Chinese purchases of US beans, taking the total last week to somewhere about 10 cargoes.
This despite a Chinese auction of soybeans from state reserves last week, and talk of further sell-downs.
In China itself, soybean futures for January added 0.8% to 4,385 yuan a tonne.
'Dryness to continue'
Furthermore, the weather forecast for the US, while hardly that worrying, is not totally benign, as soybeans begin their sensitive pod-filling stage.
The worry is dryness in the western Corn Belt, and while the weekend brought some rain to northern Iowa, the chance of a follow-up looks low for now.
This week, "showers will be confined to eastern Michigan, Ohio, far southern Indiana, far southern Illinois, central Missouri, Kansas, central Nebraska and central South Dakota," weather service MDA said.
"Dryness is likely to continue in Iowa and northern Illinois."
At broker Phillip Futures, Joyce Liu said: "Over the next two weeks, modest temperatures expected would help boost the growth and development of soybeans.
"However, the lack of rainfall that was also expected would become an issue."
Poor price outlook?
Dry weather would also have some impact on corn too, albeit that the crop has now passed the peak of its sensitive pollination phase.
"Only 3.1 inches of rainfall has occurred in the past five weeks in the main corn producing states," Gail Martell at Martell Crop Projections said.
Still, there is no idea of a quantum shift in harvest prospects significant enough to cloud prospects of a huge harvest, and therefore mega pressure on prices.
MDA over the weekend came up with a yield of 198.9 bushels per acre for corn from its Midwest crop tour, albeit saying this likely reflected an actual figure of 171.3 bushels per acre once crop deterioration is allowed for.
"It was still surprising to see the excellent state of the corn crop in some areas, especially in north central and north western Iowa and south western Minnesota, where rainfall has been limited over the past several weeks," MDA said.
RJ O'Brien has talked of the potential for corn prices falling to about $3.50 a bushel this year, compared with a high of $8.43 ¾ a bushel reached last August.
Corn for December stood 0.1% lower at $4.52 ¼ a bushel in Chicago, where the spot September lot was 0.8% down at $4.62 a bushel, losing premium with the onset of the US harvest in southern states.
'Pennies from a short-term low'
That boded ill for wheat, for which fundamentals remain, relatively, bullish, but which has been seen as being largely weighed down by fellow grain corn, an alternative in many uses, notably livestock feed.
"If corn could bounce it would sure help give wheat a lift," Mike Mawdsley at Market 1 said.
"One would think we are pennies from a short-term low" otherwise.
Wheat's premium over corn is already close$2 a bushel, a sharp reversal from the discount seen for much of 2012.
Huge Canadian crop?
But corn was lower. And while many expected the USDA later today to cut its forecast for world wheat stocks as of the close of 2013-14, corn's price fall told.
"Any bullish projections for wheat are likely to be overwhelmed by forecasts for upgraded US corn supplies," Luke Mathews at Commonwealth Bank of Australia said.
Furthermore, there are growing ideas over the harvest in Canada too.
"Reports of the Canadian spring wheat crop reaching 30m-31m tonnes, with normal fall weather, continue to filter in," Brian Henry at Benson Quinn Commodities.
Last month's Wasde report puts the Canadian wheat crop, including a little winter wheat, at 29.0m tonnes.
Wheat for September fell 0.3% to $6.31 ¾ a bushel in Chicago. The December lot was 0.3% down at $6.45 ½ a bushel
'Stressed the crops'
Among soft commodities, cocoa got off to a soft start on profit-taking, after its best week last week in more than a year.
"In Ivory Coast, the top global grower of cocoa faced dry weather which stressed the cocoa crops and affected production," Ms Liu noted.
"Ivory Coast's forward sales made last month were above expectations and that could result in reduced selling in the market, possibly driving up prices going forward."
Cocoa for December eased 0.6% to 2,465 a tonne in New York.
Cotton for December shed 0.4% to 88.57 cents a pound, with the Wasde expected to lift the forecast for world inventories.
