When natural disasters happen, there are always some companies that can turn the circumstances in their favor. Recent downpours in the Midwest provided such an opportunity as they came not only with high damages for people in the area, but also with floods for crop production, causing even higher agricultural commodity prices. The rise in corn and soybeans prices could easily lead to an increased demand for seeds, agricultural equipment, and fertilizers. BusinessWeek suggests some big names to invest in that could offer us the advantages we are looking for.

One such company is Archer Daniels Midland (NYSE: ADM), which could also benefit from higher ethanol prices, after purchasing seven businesses in 2007. Bunge Limited (NYSE: BG) is also amid possible winners, having forecast better-than-expected fertilizer earnings. Shell eggs producer Cal-Maine Foods (NASDAQ: CALM) is also on the selected list; the company saw its shares climb 15% year to date, and has just revealed a new dividend payout policy.

Another important name is Mosaic Co. (NYSE: MOS), whose stock prices have surged 70% so far this year. BusinessWeek cites Mosaic as being able to benefit from higher prices for fertilizer and potash. Following the same logic, the article points out potash provider Potash Corp. of Saskatchewan (NYSE: POT) and fertilizer distributor CF Industries Holdings (NYSE: CF), which should be able to take advantage of the weak dollar and higher sales prices.

A big crop report released this morning is once again bringing a lot of attention to corn and the global demand for ethanol. It all makes sense. With democracy and capitalism flourishing around the world, the demand for energy will boom and ethanol is a viable way to provide lower emissions fuel.

Even President Bush in his State of the Union address called for the United States to become less dependent on foreign oil. His solution: corn-based Ethanol?

However, as a reminder, investing is about "skating where the puck is going to be" as hockey great Wayne Gretsky used to say. Or as legendary John Templeton would say, look for points of "maximum pessimism."

There is little that is pessimistic about the outlook for corn today. Farmers throughout the U.S. are going to be planting it this season. Why? Because corn prices are approaching 10-year highs and the wide-spread belief is there is money to be made.

Conversely, the argument to invest in cotton might be more compelling. In a Barron's interview (subscription required) in January, Art Samberg of Pequot Capital said while cotton consumption in the US has been in decline, China's consumption, which has been growing nicely, is picking up more steam. Cotton consumption in the U.S. has fallen from 12 million to 5 million bales a year due to the growth of polyester and other materials. However, Textile spending is on a big upswing in China -- up 27% in '06, after jumping 36% in '05. Chinese consumption, which had been growing 4% to 6% per year, is now growing 15% per year.

Samberg said go long the December '07 cotton contract. Strong corn and soybean prices means U.S. farmers are going to remove acreage from cotton to earn better profits in corn and soybeans.

Supposedly, there have only been four times since 1913 when cotton was this cheap relative to grains like corn and wheat, with the last time being 1974. From 1974 to 1976, cotton tripled in price.
