Check out the price for fertilizers. Phosphate is up to $1,000 a ton from just $365 last year. The Wall Street Journal reports today:

At a time when food prices are soaring world-wide, so is the price of fertilizer, producing huge profits for leading fertilizer makers and stirring anger among farmers in the U.S. and India.

Fertilizer prices are rising faster than those of almost any other raw material used by farmers. In April, farmers paid 65% more for fertilizer than they did a year earlier, according to the U.S. Department of Agriculture. That compares with price increases of 43% for fuel, 30% for seeds and 3.8% for chemicals such as weedkillers and insecticides over the same period, according to Agriculture Department indexes.

Those skyrocketing costs are making it harder for farmers to expand their harvests in response to the global food crisis that has sparked rioting, rationing and export controls in many countries. Food prices have soared in recent months as the world's growing demand for grain, which has exceeded production for much of this decade, has reduced stockpiles to extremely low levels.

This may be tough news for consumers, but it's excellent news for stocks like Mosiac (MOS) and Potash (POT).
