In light of recent discussion, I just thought that some of you would be interested in this NY Times article about the upcoming growing season.
http://www.nytimes.com/2007/03/31/business/31corn.html?th&emc=th I found it interesting that the corn-ethanol system is considered a "renewable fuel" despite the high-input nature of the system, not to mention adverse effects of N fertilizer runoff, soil degradation, and increased N2O flux from soil. Are there any good analyses that conclude corn based ethanol is indeed a renewable fuel? Are there any studies that review N2O production in different cropping systems (ie if acreage of soybean declines due to corn increase)? In terms of greenhouse gas emissions, is there a net decline? -Matthew Warren --------------------------------- It's here! Your new message! Get new email alerts with the free Yahoo! Toolbar.
