2015 was one of those years that investors in Potash Corporation (POT) will want to forget. Having been slashed in half by the time the year wrapped up, Potash ended up hugely underperforming the broader market as well as peers Mosaic (MOS 0.11%) and Agrium (NYSE: AGU).

While industry headwinds hurt every fertilizer producer, Agrium's diversified portfolio that includes resilient products like seeds and Mosaic's smaller exposure to potash markets saved them from suffering Potash's fate.
