Thanks to the efforts of a dedicated science teacher from New Jersey, a valuable piece of soil science history is now available for viewing and research among the special collections at USDA’s National Agricultural Library (NAL) in Beltsville, Maryland.
Jill Guenther, who has taught Earth and space science for 29 years, discovered the antique soils collection tucked away in a classroom cabinet. “I knew it was something special, and I wanted to use it as a display when teaching erosion and conservation issues,” she explained.
