Potash Corporation of Saskatchewan (NYSE:POT) is often considered one of the best dividend stocks in the fertilizer industry. The company pays out a major portion of its free cash flow to shareholders, has paid a dividend every quarter since 1990, and yields more than 6% at current prices. However, there's more than meets the eye, and there are strong reasons for income investors to choose Mosaic Company (NYSE:MOS) over PotashCorp now.

Mosaic's dividend offers far greater potential to grow in the near future, and I don't say this based on PotashCorp's recent dividend cut, which was also its first ever. There are bigger and better reasons to opt for Mosaic, some of which may surprise you. Take a look at the following slideshow to learn more.
