Cargill spun off the fertilizer company called Mosaic in 2004. A hot world market for fertilizer has helped propel Mosaic stock from $15/share in 2004 to $94.34/share at the end of 2007. In fact, the Minneapolis-based company was the top earner of a local stock index with a 342% increase in price during 2007. With the fertilizer shortage continuing indefinitely, Mosaic is sure to keep climbing upward.
