Farmers will abandon more fields as dry weather compounds already below-normal moisture in growing areas from Texas to Alabama, John Flanagan, the president of Flanagan Trading Corp, told Bloomberg News.
"We shouldn't expect to see the crop emerge as healthy as this year," Flanagan said.
Still, rising prices may help push planted acreage to 13.5 million acres next season, Flanagan said. The government estimates that 11.04 million acres were sown this season.
La Nina, a weather pattern caused by cooling equatorial waters in the Pacific Ocean could mean more dry weather during planting.
"There is a dryness risk in West Texas in the planting season" that will likely last into May, said Joel Widenor, Commodity Weather's director of agricultural services.
