Scientists compile field studies across U.S. to identify influences on biomass yield While scientists have conducted numerous studies on production of biomass from biofuel crops, such as switchgrass, no one has yet compiled this information to evaluate the response of biomass yield to soils, climate, and crop management across the United States. A team of researchers from Oak Ridge National Laboratory and Dartmouth College published just such a study in the July-August 2010 Agronomy Journal,...

Researchers at North Carolina State University have developed a more efficient technique for producing biofuels from woody plants that significantly reduces the waste that results from conventional biofuel production techniques. The technique is a significant step toward creating a commercially viable new source of biofuels. "This technique makes the process more efficient and less expensive," says Dr. Ratna Sharma-Shivappa, associate professor of biological and agricultural engineering at NC...

THOUSAND OAKS, Calif., June 30 /PRNewswire/ -- Energy crop company Ceres, Inc. announced today that it has developed a plant trait that could bring new life to millions of acres of abandoned or marginal cropland damaged by salts. Results in several crops, including switchgrass, have shown levels of salt tolerance not seen before. Ceres reported that its researchers tested the effects of very high salt concentrations and also seawater from the Pacific Ocean, which contains mixtures of...

Money may not grow on trees, but gasoline, computers, and tennis shoes just might thanks to new biotech advances that could allow manufacturers to produce fuel, plastics, and other chemicals from plants instead of petroleum. That's the topic of an article in the current issue of Chemical & Engineering News (C&EN), ACS' weekly newsmagazine. C&EN Senior Business Editor Melody Voith notes that today's plant-based fuels and plastics involve growing crops and then using physical and...

HAYWARD, Calif., May 18 /PRNewswire/ -- Mendel BioEnergy Seeds, a division of Mendel Biotechnology, Inc., announced today that average two-year yields of its numerous varieties of Miscanthus indicate that Mendel's lead product candidates are on track to meet or exceed current commercial targets for biomass production from dedicated energy crops. The most promising yields reported were from Mendel's proprietary varieties of Miscanthus giganteus, a sterile, non-invasive species. Miscanthus...

Native grass fares well as alternative growing medium Loblolly pine bark is the primary component of nursery container substrates in the eastern United States, but a shortage of the widely used organic material is prompting researchers to investigate new materials as potential alternatives. A recent study by James E. Altland and Charles Krause of the USDA Agricultural Research Service at the Ohio Agricultural Research and Development Center was designed to determine if ground switchgrass can...

Biofuels processors who mill switchgrass into fine bits to help its flowability should be able to save time, energy and money by not doing so, a Purdue University study shows. Switchgrass can be used in a number of biofuel applications, but moving it - especially feeding it into boilers - can be problematic, said Klein Ileleji, an assistant professor of agricultural and biological engineering. While corn and soybeans are round and spherical, switchgrass is shaped more like matchsticks,...

The scramble to find sufficient land for biofuel production has experts eyeing marginal croplands that have been placed in the Conservation Reserve Program (CRP). Now a study by Agricultural Research Service (ARS) scientists indicates that plant species diversity and composition are key factors in potential energy yield per acre from biomass harvested from CRP land. Agronomist Paul Adler, who works at the ARS Pasture Systems and Watershed Management Research Unit in University Park, Pa., led...
