Days after Congress voted to ramp up the government mandate for corn ethanol, bringing it to fully three times current production levels within a decade, we get bracing news from the Gulf of Mexico.
The nation's corn crop is fertilized with millions of pounds of nitrogen-based fertilizer. And when that nitrogen runs off fields in Corn Belt states, it makes its way to the Mississippi River and eventually pours into the Gulf, where it contributes to a growing "dead zone" -- a 7,900-square-mile patch so depleted of oxygen that fish, crabs and shrimp suffocate.
This year, the dead zone has reached its third-largest size ever. And with the ethanol boom inspiring farmers to plant ever more corn, activists are bracing for more bad news.
"We might be coming close to a tipping point ... The ecosystem might change or collapse as opposed to being just impacted," an official for the Gulf Restoration Network told AP.
Although farmers in the Midwest can feel the pain of their fishermen peers in the Gulf, their empathy can only go so far. As one Iowa farmer told AP, "I think you have to try to be a good steward of the land ... But on the other hand, you can't ignore the price of corn."
In other words, the market isn't paying him to take care of the streams that carry nitrogen runoff from his property. Rather, it's telling him to grow as much corn as possible.
The dead zone may be an unintended consequence of the government-generated ethanol boom; but it's surely no surprise. It's been happening every year since 1985, and its size is trending upward.
We're sacrificing a robust habitat, source of protein, and traditional livelihood in the Gulf to create a fuel of dubious value.

Cost and Source of Nitrogen
Please excuse the lengthy excerpt, but I think you will find the following article very relevant to our ongoing ethanol discussion and debate. This article gives some perspective on the size of the 2008 corn crop, how much nitrogen has been applied for it this fall, prices of nitrogen as affected by the cost of natural gas, and the source of nitrogen.
We now import 80% of the nitrogen. Some of this is coming from Russia. Didn't we get a lecture recently from a Mr. Coleman about not being concerned enough about importing oil from Russia? And how homegrown ethanol makes us more secure?
As I have predicted in earlier comments, the economics of production will rattle the cage of ethanol more than any of our expressions of outrage. Let's hope that we don't get caught up in an inflationary spiral that brings us all down with it.

Interesting ...
I know several farmers and they say that liquid anhydrous ammonia is horrible stuff ... it burns the ground (sour acidification), burns the tractor workers, and crisps the soil so it even leaches and erodes more.
My notes - In addition the liquid nitrogen fertilizers readily release N20, a greenhouse gas, as well as perhaps nitrogen oxides (NOx), a precursor for ozone formation.
Back to the farmers, they mentioned that granulated fertilizer was far superior but much more expensive to apply, although some slurry applications (granulated in water) seemed to work. The granulated or slurry approach can also apply needed phosphorus, potassium, and other trace minerals.
As to the dead zone in the Mississippi Bight, I'm not sure why it is so large because corn production was at similar levels during WWII - maybe we're using much more fertilizer that runs off now, called over ferilization. But as a side note, when Hurricane Emanuele made landfall this summer, a huge area consisting of a freshwater "dead zone" formed, so visible it could be seen from outer space. /sam

Whenever you see stories like these...
just think perverse subsidies and remind yourself that eliminating these should be environmentalists' top priority.

Nitrogen in the Dead Zone may turn to N2O
According to a recent study by Dr Mark Trimmer of Queen Mary (University of London)'s School of Biological and Chemical Sciences:
I'd be interested to know whether he expects the same is happening in the Gulf of Mexico's Dead Zone.
If so, it is not just nitrous oxide releases from the soil that we need to be concerned about.

Happy Greenings!
We are growing "green" jobs here. John Deere is growing the shit out of green machines. People are driving big "green" FFV pickups and SUVs on all that green corn that is bring more "green" backs to Big Green AG. So we are turning the Gulf "green". Green is good. Eat green. Drink green. Smoke green. Drive green. Be green. Be happy.
Greenings to all!
