U.S. food prices may ease later this year now that farmers have planted the second-largest corn crop in nearly seven decades.
The size of this year's corn crop will be 92.3 million acres, the U.S. Agriculture Department said Thursday. That's 9 percent larger than the average annual corn crop over the past decade. The only crop bigger in the past 67 years was planted in 2007.
Many analysts had worried that wet weather this spring would cut the number of corn acres. But record-high prices are encouraging farmers to use more acres for corn, and less for soybeans and wheat.
A greater crop estimate drove corn futures down 30 cents in morning trading, to $6.21 per bushel. That's the maximum price change allowed by futures exchanges. Corn rose to a record high of $7.99 per bushel earlier this month.
More expensive grain has led to food price increases this year. That could ultimately make everything from beef to cereal to soft drinks more expensive at the supermarket. For all of 2011, the USDA predicts food prices will rise 3 percent to 4 percent.
A huge harvest in August could ultimately slow food inflation. It typically takes six months for changes in commodity prices to affect retail food prices in the U.S. Analysts say consumers could see some relief at the supermarket by early 2012.
"All of us who perceived tighter (corn) supplies up to this point, all of us were proven wrong today," said Jason Ward, an analyst with Northstar Commodity in Minneapolis.
Industry traders had expected just 90.8 million acres of corn had been planted. Knowing that far more corn is in the pipeline will likely pull down grain prices dramatically this summer, Ward said.
Farmers chose to plant corn at the expense of this year's soybean crop. They used only 75.2 million acres of soybeans, about 3 percent less than last year. Farmers have a limited supply of good farmland and usually trade one crop for another on their acreage.
Backup supplies of corn are expected this year to hit their lowest level since 1995. The high price of corn has boosted inflation for other crops. Expensive corn makes crops like soybeans and wheat more expensive because farmers plant less of them.
Raised expectations for this fall's corn crop also helped lower soybean prices in trading Thursday. Soybeans fell 23 cents to $13 a bushel. , the maximum amount allowed by futures exchanges.
A bigger crop doesn't guarantee lower food prices. A drought or flood could limit the size of the harvested crop. Ward said many of the acres planted this spring were on marginal land that won't yield much grain. Many farmers planted during wet weather just because they knew they could get the crops insured.
"They have no intention of harvesting them because they were planted in complete mud," Ward said.
Corn is the main ingredient in feed for poultry and livestock, and a key staple in many processed foods. When corn prices rise, food processors and grocers pass along the higher costs to the consumer.
Surging corn and soybean prices are showing up at the grocery store this summer. In May, a sirloin steak cost about 7 percent more than last year, according to the most recent available Bureau of Labor Statistics figures. The price of pork chops jumped 9 percent. The price of spaghetti and macaroni noodles, which often contain soybean meal and corn syrup, jumped 13 percent.
