Corn futures are trading higher at midday. Weakness in the U.S. dollar and strength in crude oil are supporting trade. A private acreage forecast on Friday that called for strongly lower corn acreage in 2009 is also providing support. Gains have been trimmed slightly at midday by weakness in the stock market. March is 6 1/2 cents higher at $3.80 and July is 6 1/2 higher at $4.01 3/4.

Soybean futures are slightly higher at midsession. The market is being supported by weakness in the dollar index and strength in crude oil. However, gains are being trimmed by losses in the stock market and the private estimate on Friday that is calling for increased soybean acreage in 2009 while corn and wheat areas decline. January is 2 3/4 cents higher at $8.56 3/4 and March is 4 1/4 cents higher at $8.60 1/2.

Wheat futures are posting solid gains at midday. Outside markets are supportive as the dollar index is sharply lower while crude oil moves higher. Weather is slightly supportive as very cold temperatures are invading the Plains, although no significant damage is expected from the cold snap. CBOT March is 12 cents higher at $5.25, KCBT March is 10 cents higher at $5.48 1/4 and MGE March is 6 1/2 cents higher at $5.96 1/2.

Cattle futures are trading higher at midsession. Weakness in the dollar and strength in crude oil are supporting ag commodities. Gains are being limited by a lower stock market this morning. Cash fundamentals also remain bearish as boxed beef prices continue to decline and as cash trade developed at mostly $85 last week, down $2 from the previous week. February is 28 cents higher at $83.08 and April is 38 cents higher at $85.33.

Lean hog futures are higher at midday. The rally in crude oil and weakness in the dollar are providing some buying interest despite future's premium to cash and lower pork prices on Friday. Demand has slowed seasonally as holiday buying from wholesalers has slowed. Cash markets are mostly steady as cold weather has slowed marketings although most packers have needs covered for the week. February is 18 cents higher at $62.45 and April is 48 cents higher at $68.25.
