3:29 p.m., Aug. 6, 2008----Did you know that there are more living creatures in a tablespoon of soil than there are people on the Earth? This and other fun soil facts are brought to life thanks to UD soil scientists, scientists from across the country and many state partners, in the newest exhibit at the National Museum of Natural History in Washington, D.C. “Dig It! The Secrets of Soil” opened July 19 and features 5,000 square feet of educational exhibit space dedicated to soil and its life-sustaining properties.

Tom Sims, associate dean for academic programs and research for UD's College of Agriculture and Natural Resources and the T. A. Baker Professor of Soil and Environmental Chemistry, and Don Sparks, S. Hallock du Pont Chair of Plant and Soil Sciences and director of UD's Center for Critical Zone Research, were instrumental in Delaware's contributions to the exhibit. The soils and environmental quality program at UD, in the Department of Plant and Soil Sciences, is nationally recognized for addressing soil resources as they relate to agricultural and environmental challenges.

These two prominent UD soil scientists served as president of the Soil Science Society of America (SSSA) in 2002-04 and 2000. respectively. Sparks also served as president of the International Union of Soil Sciences from 2002-06. During these time periods, they worked on exhibit development.

“Soil scientists throughout the U.S. worked with the design team at the Smithsonian for nearly eight years to create a world-class educational exhibit that illustrates the fundamental importance of soils to life on Earth," said Sims, who served on the steering committee for the project. "The SSSA took the lead in developing the exhibit, but we were very fortunate to have the support of the National Academies, hundreds of soil conservation districts, all major USDA agencies and the private sector in our efforts to raise the more than $2 million needed to create the 'Dig It' exhibit.”

Sims added, “As Pat Megonigal, lead curator for the exhibit and SSSA member stated, 'Soils represent the biggest gap between the importance of a natural resource and its appreciation by the public.' After viewing the exhibit, I'm confident that visitors to the Smithsonian will have a much greater understanding of how important soils are not only to food, fiber and energy production, but to sustaining the quality of our environment for future generations.”

“The exhibit is a wonderful way to showcase to the public the incredible role that soil plays in our daily lives,” Sparks said. “Soils are the foundation for life and are critical in sustainability of human welfare, ecosystem health, food production, carbon sequestration and an array of other areas.”

“Dig It!” uses interactive displays, hands-on models, videos and soil samples to guide visitors on a quest to learn more about soil as an often overlooked but vastly important resource and ecosystem. Through the 5,000-square-foot exhibit, visitors will look at the “skin” of the Earth, see how soils are formed and learn about their characteristics, learn how soils play a part in both life and death, investigate how soils are important to environmental issues like water quality and global warming, and find out how soils play an important role in the everyday life of everything from worms to people.

There is even an interactive exhibit that highlights each state's soil, including Delaware's own Greenwich loam. In 2000, then Gov. Thomas R. Carper, through the sponsorship of state Rep. V. George Carey, signed House Bill 436 establishing Greenwich loam as the official state soil of Delaware. When the exhibit commenced development and the SSSA was looking for supporters, Carey approached the Delaware State legislature for support.

“If we are good stewards of the soil, it can provide for us forever," said Carey, who farms in the Slaughter Neck area near Milford, Del. "Soil will give back to us what we put into it. This exhibit will help people to understand how important soil is not only to farmers, but to everyone.”

Each state was asked to raise funds to support its state's soil exhibit. “We are grateful for the generous support of the exhibit by a number of Delawareans, the state legislature through the efforts of Rep. George Carey, and the Sussex County Council,” Sparks said,

UD alumni working in the soil sciences also were instrumental in contributing to Delaware's efforts. The Carski Foundation, with encouragement from alum Ted Carski, AG '86 Ph.D., made significant contributions to reach the fundraising goal.

“The foundation is a family foundation, initiated by my grandfather to support education," said Carski, a global registration product manager for DuPont Crop Protection, a member of the UD College of Agriculture and Natural Resources advisory board and an adjunct professor in the Department of Plant and Soil Sciences. "This exhibit fits perfectly in terms of educating others about the importance of soils not only for agriculture but environmental quality.”

“We are also grateful to the Mid-Atlantic Association of Professional Soil Scientists (MAPSS),” said Sims. “They also helped to raise the funds needed for the Greenwich soil exhibit, and made many personal contributions to the Smithsonian for the new exhibit.”

“It was definitely a group effort," said Ian Kauffman, a MAPSS member and supporter of the project. "We had so many different people, professionals and nonprofessionals alike, who contributed individually and through their businesses. When we first started fundraising for the exhibit, Hurricane Katrina hit. In the spirit of pulling together for the exhibit, MAPSS made a contribution to the exhibit in the name of Louisiana's professional association of soil scientists, helping to get them their state soil exhibit.”

At the conclusion of the exhibition at the National Museum of Natural History on Jan. 3, “Dig It!” will travel to 10 museums throughout the U.S. through 2013 via the Smithsonian Institution Traveling Exhibition Service.
