The making of the Secrets of Soil exhibit

At the 2008 Joint Annual Meeting in Houston, the Smithsonian's Design Team will explain details about the making of the new Dig It the Secrets of Soil exhibit that recently opened at the Natural History Museum in Washington, DC. Jennifer Bine, Pat Megonigal, and Barbara Stauffer will talk about how the designs were brought to life, the popularity of the exhibit with the public, and planning for the exhibit to travel. The "Update on the Soils Exhibition Debut," will be held on Wednesday, 8 October from 2:30 to 3:30 pm in Room 381ABC of the George R. Brown Convention Center, Houston, TX.

Texas's state soil, "Houston Black," is featured in the new 5,000-square-foot exhibition. Texas's very own Houston Black soil is proudly displayed as one of 54 soil samples in the exhibition, representing each U.S. state, territory, and the District of Columbia. These soils were selected for Dig It! because of their special significance to each state or region.

The Houston Black soils are characterized as vertisols with high shrink-swell with changes in soil moisture; surface is black clay; sugsoil is black clay with slickensides grading to containing calcium carbonates; substratum is light olive brown clay; form under prairie vegetation in calcareous clays and marls

Houston Black soils can be used for cropland - grain sorghum, cotton, corn, small grain, forage grasses; high shrink swell limits site development.

In the two months since the exhibit opened, an estimated 300,000 people have been though the exhibition. Visitor responses have been enthusiastic, with young children, teenagers, and adults alike commenting on how cool, weird, and interesting soils are. Later this year, the museum plans to conduct a comprehensive visitor survey to asses what visitors are learning as they go though the exhibition. The Smithsonian team hopes to reach even more people with its recent launch of the exhibit web site at http://forces.si.edu/soils/.

Gary A. Peterson, SSSA President said, "As a member of SSSA, you can be very proud of Dig It! as it is truly a world-class exhibition that is already attracting large numbers of visitors, many of whom are under the age of 16. The exhibition is a huge step forward in our efforts to educate youth about soils and to pique their interest in studying soils."

The next step is to take Dig It on the road. SITES, the Smithsonian Institution, Traveling exhibition service, is already preparing the exhibition for a four-year journey across North America, marketing it to a prospective large host museums and science centers. Discussions are proceeding with a several potential venues.

Senate resolution shines spotlight on the importance of soils
The Soil Science Society of America (SSSA) applauds the visionary action taken by Senator Sherrod Brown and his colleagues in the Senate who helped usher in legislation to recognize soils as an "essential" natural resource, placing soil on par with water and air. On June 23, Senator Brown was joined by co-sponsoring Senators Kent Conrad (D-ND), Charles Grassley (R-IA), Russ Feingold (D-WI), Tom Harkin (D-IA), Ken Salazar (D-CO) and George Voinovich (R-OH) to successfully pass Senate Resolution 440, which also highlights the "critical role" soils professionals play in managing our nation's soil resources. "This resolution comes at a time when soil is widely undervalued," says Rattan Lal, Ohio State University, SSSA Past President. "Soil, and specifically sound soil management, is essential in our continued quest to increase the production of food, feed, fiber, and fuel while maintaining and improving the environment, and mitigating the effects of climate change. Being the essence of all terrestrial life and ecosystem services, we cannot take the soils for granted. Soil is the basis of survival for present and future generations." The Senate resolution passed six months after the European Union's Soil Protection Framework was tabled due to irreconcilable differences among Parliament membership. Continued at Eureka Alert
 
Put your trash to work
Going green involves some brown. Advertisement Composting is championed as one way every person can helps conserve resources. "Yard trimmings and food residuals together constitute 24 percent of the U.S. municipal solid waste stream," according to U.S. Environmental Protection Agency Web site www.epa.gov/compost. "That's a lot of waste to send to landfills when it could become useful and environmentally beneficial compost instead." The end result improves soil quality. "Compost binds with the soil particles in fine-textured clay soil, making these soils easier to work," University of Tennessee plant and soil science professor David W. Sams states in the agricultural extension handout "Making and Using Compost." "This also improves aeration, root penetration, water infiltration and availability... continued at: jacksonsun.com

 

 
D.C. museum puts dirt on display
Dishing the dirt has a long history in Washington, but the Smithsonian Institution is taking it to new depths. The National Museum of Natural History opens a new exhibit on Saturday "Dig It" exploring the mysterious and complex world of soil. "We want people to walk away understanding that soils are living, living breathing bodies," said exhibit curator Patrick Megonigal, a soil ecologist at the Smithsonian Environmental Research Center in Edgewater, Maryland. "One of the most important messages for me is that people get beyond thinking of soil as something in their garden, but think of it as the foundation of all the Earth's ecosystems," as important as air and water, he said.

Synthetic biology's role in agrofuels
The debate on next-generation agrofuels could be transformed by the new field of synthetic biology. Also known as synbio, synthetic biology goes beyond genetic engineering to create life from scratch by combining nanoscale biology, computing, and engineering. "Using a laptop computer, published gene sequence information, and mail-order synthetic DNA, just about anyone has the potential to construct genes or entire genomes from scratch," informed the ETC Group in a recent report. "At the core of synthetic biology is the belief that all the parts of life can be made synthetically, engineered, and assembled to produce working organisms." Continued at BioEnergy
