MOSCOW — American farmers are getting an unexpected windfall from a contentious fight between Russia and Belarus, a former Soviet splinter state.
The subject of the fight is potash, a fertilizer. The score so far: One imprisoned Russian business executive, the disintegration of a once-effective cartel that kept world potash prices high and political tension between the two countries.
What is being called the “fertilizer war” is the latest of numerous trade and economic spats between Russia and Belarus, whose leaders, though presiding over similar autocratic political systems, do not get along personally, Russian political analysts say. Aleksandr G. Lukashenko, president of Belarus, and Vladimir V. Putin, president of Russia, by most accounts detest each another. Their feelings have spilled over into the fertilizer business.
The potash problem reached a peak on July 30, when Uralkali, the Russian potash company, announced it was withdrawing from an international cartel called the Belarusian Potash Company, or B.P.C., which was created to keep prices high.
