In North America, windbreaks are an effective carbon-capturing option. Only occupying about 2 to 5% of the land, windbreaks also help protect crops and livestock, as well as reduce wind erosion. They provide a means to increase production while reducing greenhouse gases.
James Brandle, a University of Nebraska–Lincoln professor, explains that unlike forests, the linear design of windbreaks creates a more open environment with different light and climate conditions. As a result, agroforestry trees usually have different characteristics than trees grown under forest conditions. New tools specifically designed for windbreak trees are needed to determine current or future amounts of carbon contained in agroforestry practices.
Researchers at the University of Florida, University of Kansas, University of Nebraska and the USDA National Agroforestry Center (NAC) have developed a model to predict the amount of carbon contained by agroforestry systems. This modeling approach uses detailed web-available data for windbreak, soils and climate.
While this research focused only on green ash windbreak growth in Nebraska, it provides a good basis for determining agroforestry’s contributions in farming operations.
This research was supported by the Research Joint Venture Agreement through the USFS Rocky Mountain Research Station, Forest Service, and the McIntyre-Stennis Forestry Research Program at the University of Nebraska. The complete results from this study were published in the May/June 2011 issue of the Journal of Environmental Quality.

The Journal of Environmental Quality is a peer-reviewed, international journal of environmental quality in natural and agricultural ecosystems published six times a year by the American Society of Agronomy (ASA), Crop Science Society of America (CSSA), and the Soil Science Society of America (SSSA). The Journal of Environmental Quality covers various aspects of anthropogenic impacts on the environment, including terrestrial, atmospheric, and aquatic systems.
The American Society of Agronomy (ASA) www.agronomy.org, is a scientific society helping its 8,000+ members advance the disciplines and practices of agronomy by supporting professional growth and science policy initiatives, and by providing quality, research-based publications and a variety of member services.
The Soil Science Society of America (SSSA) is a progressive, international scientific society that fosters the transfer of knowledge and practices to sustain global soils. Based in Madison, WI, SSSA is the professional home for 6,000+ members dedicated to advancing the field of soil science. It provides information about soils in relation to crop production, environmental quality, ecosystem sustainability, bioremediation, waste management, recycling, and wise land use.
SSSA supports its members by providing quality research-based publications, educational programs, certifications, and science policy initiatives via a Washington, DC, office. Founded in 1936, SSSA celebrates its 75th Anniversary this year (2011). For more information, visit www.soils.org or follow @SSSA_soils on Twitter.
The Crop Science Society of America (CSSA), founded in 1955, is an international scientific society comprised of 6,000+ members with its headquarters in Madison, WI. Members advance the discipline of crop science by acquiring and disseminating information about crop breeding and genetics; crop physiology; crop ecology, management, and quality; seed physiology, production, and technology; turfgrass science; forage and grazinglands; genomics, molecular genetics, and biotechnology; and biomedical and enhanced plants.
CSSA fosters the transfer of knowledge through an array of programs and services, including publications, meetings, career services, and science policy initiatives. For more information, visit www.crops.org.

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
