Millions of farm acres are set to go unplanted with corn this spring as persistent wet weather leaves U.S. farmers facing an agonizing choice: whether or not to risk trying to raise a crop, the Wall Street Journal reported. Heavy, repeated rains over the past two months have left fields saturated throughout the critical planting period for corn, typically the biggest U.S. crop by acreage. Farmers in rain-soaked states now must decide whether to file insurance claims on unplanted fields (potentially making less money off their farms), switch to less-profitable crops or take their chances sowing corn that may not have time to fully mature. The inclement weather adds another challenge to a punishing period for farmers, seed and chemical suppliers, and tractor makers. Trade disputes with major U.S. food importers including Mexico and China have cut into crop prices, adding pressure to farm incomes, after several years of bumper harvests swelled global grain supplies.
