The USDA says American farmers expect to plant a record soybean crop this year.
The estimated 84 point 6 million acres would be up 1 per cent from last year.
Planned corn acreage is down 2 per cent from last year at 89 point 2 million acres.
The USDA says that would be the third straight year of lower corn acreage and the lowest acreage planted to that crop in the U-S since 2010.
All wheat acreage planted is expected to be 55 point 4 million acres, down 3 per cent from 2014.
The USDA's grain stocks report has U-S corn stocks up 11 per cent from a year ago, soybean stocks up 34 per cent and all wheat stocks up 6 per cent.
However, DTN analyst Todd Hultman says the rate of disappearance is the more important factor.
He points out 50 per cent of the beginning corn supplies and 67 per cent of the beginning soybean supplies have been used after the first two quarters of the 2014-15 crop year.
Hultman considers the grain stocks report to be neutral to bearish for corn, bullish for soybeans and wheat.
The DTN analyst feels the planting estimates are bearish for new-crop corn, bullish for new-crop soybeans and neutral for new-crop wheat.
