An Associated Press story on the wire about ethanol producers being encouraged by “new study” is the study that came out at the end of January (see previous post) Just want to make that clear in case someone sees the story and thinks that this is a different “new” study. It is a very positive story for the ethanol industry, so it’s good to see it resurface for another round. This story, which datelined in Iowa, interviews one of the University of California-Berkeley researchers who did the study. Alex Farrell, co-author of the latest study, said previous research didn’t take into account ethanol byproducts such as distiller grains and corn oil. Corn turned into ethanol also feeds animals and is used for other purposes, he said, which displaces competing products that require energy to make. “Studies with a negative impact ignored that,” Farrell said. Since the latest research wasn’t funded by any special interest group and used the most up-to-date data, Farrell said his group’s information is the most accurate.

Good story in USA Today about the ethanol plant construction boom. I like these quotes from the article: “It’s a little bit of a dot-com atmosphere,” says John Skelley, president of Arizona Grain” and “It’s a gold rush right now,” CEO Jeff Broin (of Broin Companies) says.

Most people never heard the word “switchgrass” before it was immortalized by President Bush in his State of the Union address, but someday we could be running our cars on fuel made from the stuff. USDA’s Agricultural Research Service just released a new study on the feasibility of switchgrass for energy production, focusing specifically on the economics of growing the crop and how to get the most yield per acre. According to an ARS report, “two switchgrass plants per square foot the first year ensures a successful bioenergy crop harvest in subsequent years.” The studies were done on farms in Nebraska, South Dakota and North Dakota, since switchgrass is a native prarie grass in those states. Normally the grass is used for conservation purposes or cattle feed. The guy in the picture is Ken Vogel, a geneticist at the ARS Grain, Forage and Bioenergy Research Unit at Lincoln, Neb. who led the study. Here’s a link to the report on “Establishment Stand Thresholds” reported in the January issue of Crop Science magazine, if you’re into that.
A big plus for switchgrass is that as a perennial plant, switchgrass has the advantage of not needing annual planting and tillage. Skipping these can save soil and energy. It can also reduce sediment and other pollutant losses to waterways.
By the way, research into switchgrass for energy production has been going on for at least a decade. I know that because I remember doing a story about it when I still worked at Brownfield Network – and I left there in 1997!
