Remember the 2012 droughts that ravaged a meaningful portion of the U.S. corn and soy bean crop? If you are expecting them to occur with more regularity in the future, then miners and marketers of the fertilizer component potassium, or potash, could benefit if you turn out to be a better forecaster than your local weatherman.
When assessing the benefits of the three most common fertilizer components -- nitrogen, phosphate, and potassium -- potassium leaps out as the clear-cut choice when hoping to protect against arid conditions. The nutrient produced by companies like PotashCorp (NYSE: POT ) and Agrium (NYSE: AGU ) allows for more efficient utilization of water by corn, soy beans, and any number of other crops or plants. According to PotashCorp, treating an acre with 100 pounds of potassium has the potential to boost yields up to 50%.
Taking that math into account, it's hard to understand why farmers the world over would choose not to utilize this critical soil nutrient in some form or another. As the No. 1 producer of potash in the world, PotashCorp is much more exposed to the ebbs and flows of global demand. It received a nice boost when China finally settled contract negotiations last December, and its spring purchases should be a record. Unfortunately, many forecasts estimate that potash supply should remain well ahead of demand for at least the next five years.
All of that could change, however, with a few more droughts like the one the U.S. experienced in 2012. Because the world depends so heavily on the production of U.S. farmers, it is critical that our yields keep growing in tandem with the worldwide population. If we can maintain a rate slightly ahead of that, it would provide a buffer in down years. As arable land continues to disappear, fertilizer demand is seemingly guaranteed to rise.
Investors who are still nervous about this oversupply weighing on prices could look to Agrium for some potash exposure without the same dependence. The company's retail segment offers a revenue stream that isn't solely reliant on fertilizer demand. Its other offerings among pesticides, fungicides, and various application services still benefit from the growth in agriculture but don't necessarily play favorites between fertilizer nutrients.
For most farmers, one nutrient just isn't enough. A nutrient that has paired well in the fields with potash is nitrogen. Companies producing nitrogen-based fertilizers have been experiencing excellent margins over the last year thanks to cheap feedstocks provided by North American natural gas. With more than 80% of its revenue stemming from nitrogen fertilizers, CF Industries (NYSE: CF ) turned in a return of 32% in 2012, well above the 11.7% of the S&P 500. Unfortunately, natural gas prices have risen and likely pressured the stock a bit lower. Year to date, shares have underperformed a hot market by 18.6%. One thing investors should look for here is higher-than-expected demand because nitrogen's supply and demand balance is much tighter than that of potash. If this takes place, prices and, in turn, nitrogen fertilizer producers' stock will likely rise.
Droughts aren't the only enemy of our global food supply
With less and less arable land available around the world, increasing yields from existing plots could become vitally important to keeping up with expected population growth. Cheap and effective fertilizers could be the key to achieving this goal. As the global leader in potash production, PotashCorp has established several barriers to entry that make it nearly impossible for competition to break through.
