A flood at a Russian potash mine accounting for 3 percent of global supply threatens to force up fertilizer prices and make Potash Corp. of Saskatchewan Inc. the world’s largest producer again.

OAO Uralkali, Russia’s biggest potash miner, is monitoring the Solikamsk-2 mine about 1,000 miles (1,800 kilometers) east of Moscow after it halted operations and evacuated workers because of rising inflows of salty water into the site yesterday. Water can be deadly for potash mines because it dissolves the mineral deposits.
