In 2006, Uralkali was one of the largest producer of potash in the world with an approximate 9% share of production in 2006. In contrast to some of its competitors, who also produce nitrogen and phosphorous-based fertilizer products, Uralkali only produces potash. Nitrogen and phosphorous-based fertilizer products have historically been subject to high price volatility, mainly because of the correlation between their prices and energy prices, (primarily oil and natural gas prices). By focusing on potash, for which prices have risen significantly in recent years, but with less volatility, Uralkali believes its financial performance is subject to less volatility than that of some of its competitors who also produce nitrogen and phosphorous based fertilisers.
