UPDATE 3 (October 13, 2009) The killing freeze occurred before the crops were mature this year in the farm belt of the U.S., as shown in this article. From the article, "About a quarter of the country's corn will leave the field immature [due to the killing freeze]. As of this past weekend, about 3/4 of the nation's corn crop is fully matured, according to Tuesday's USDA Crop Progress report. That's almost 20% more than a week ago, but still almost 20% below the previous 5-year average.
Corn harvest is at a similar pace: 13% of the corn crop's out of the field, versus the previous 5-year average of 35%." It is a very good thing that there is plenty of oil for manufacturing gasoline, and natural gas for powering CNG vehicles. It is a very bad policy to rely on weather and agriculture for our nation's energy security. This year's harvest is a prime example.
