Will U.S. agriculture soon be caught up in the perfect storm?



That remains to be seen, says one Extension economist, though he does believe some gray clouds are forming on the horizon that could threaten the economic bottom line of many producers.



"The old saying that a person should take advantage of the good times but plan for the worst is still true today," says Dr. Jim Novak, an Alabama Cooperative Extension System agricultural economist and Auburn University professor of agricultural economics and rural sociology.



In the meantime, Novak says the operative word is "could"-such a storm could occur, because the "downside risk is still out there."



He cites input costs, particularly spiking energy prices, as troubling signs.



So far, farm commodity prices have held up, he says-an especially good thing for farmers in many parts of the nation, because it has allowed them to absorb the shock of rising input costs.



Nevertheless, Novak is concerned that spiking energy costs, coupled with a sagging U.S. economy and potential changes in climate, could set up a disturbing scenario for farmers.



"You have some forces aligned," he says. "Domestically, there's the weakening dollar, which makes our imports more expensive, meaning that when we buy from overseas, we pay more."



Nitrogen is a prime example. There has been between a 30 percent to 40 percent reduction in the nation's ability to produce nitrogen, and increasingly, U.S. farmers have been forced to look overseas for that critical farming input, Novak says.



"It's more expensive to buy overseas because of our weak dollar," Novak says. "Add the potential for inflation on top of that."



There is the added bad press associated with ethanol in recent months from people who criticize this alternative fuel for its adverse environmental effects and because of the indirect effects worldwide demand for ethanol is imposing on developing world farmers.



"There is a lot of criticism, whether warranted, regarding ethanol, and it could affect the demand for the product," Novak says.

And he fears adverse effects on the demand for ethanol feedstocks, such as corn, conceivably could pull the rug out from under many who are heavily invested in this technology.



The high prices farmers are getting for ethanol feedstocks also could be threatened by advances in other energy technologies, including cost-competitive ways of getting oil from shale.



Climate change could also be a factor in changing the supply situation, Novak says.



For the last couple of years, farmers have been dealing with a La Ni
