Several fertilizer makers are climbing after Agrium (AGU), which develops agricultural nutrients, reported higher than expected preliminary fourth quarter earnings per share, or EPS. Agrium estimated that its EPS would be slightly above $2, versus analysts' consensus estimate of $1.73. The company's CEO, Mike Wilson, said that its fourth quarter results benefited from "a very strong finish to the fall application season in North American retail operations, supported by an extended fall season in the U.S. and continued strength in grain and oilseed prices." The Spring season is expected to be strong, due to continued strength in crop prices and low global grain inventories, Wilson added. In mid-afternoon trading, Mosaic (MOS) rose 2.42% to $60.90, Potash Corp. (POT) gained 1.52% to $42.63, CF Industries (CF) added 1.54% to $227.23, Intrepid Potash (IPI) jumped 3.70% to $22.71 and Agrium advanced 2.49% to $113.64.
