CHICAGO (AP) -- Grain and soybean futures prices retreated Friday on the Chicago Board of Trade amid perceptions weather will remain favorable for farmer fieldwork. Wheat futures faced continued pressure from the early harvesting of winter wheat crops, where farmers were reporting above-average yields. Corn futures sank amid expectations the government next week will report the pace of planting accelerated following generally clear skies in the Midwest. Soybeans retreated after a National Oilseed Processors Association report showed an anemic pace for crushing soybeans into oil and meal. Futures prices also were pressured by expectations the pace of soybean plantings will accelerate next week. Farmers are expected to plant record acreage, setting the stage for a bumper fall harvest. Wheat for July delivery fell 4 cents to $2.52 1/4 a bushel; July corn fell 3/4 cent to $2.18 1/2 a bushel; July oats fell 1 cent to $1.20 1/4 a bushel; July soybeans fell 6 1/4 cents to $4.61 3/4 a bushel. Feeder cattle and lean hogs were mixed on the Chicago Mercantile Exchange, while live cattle advanced and pork bellies retreated. June live cattle rose .65 cent to 63.52 cents a pound; August feeder cattle rose .40 cent to 75.02 cents a pound; June lean hogs rose .40 cent to 56.90 cents a pound; July pork bellies fell .45 cent to 53.60 cents a pound. -=-=-
