Soil is the reservoir on which most life on earth depends, as the primary source of food, feed, fuel, forage, fiber, and pharmaceuticals.
Soil plays a vital role in sustaining human welfare and assuring future agricultural productivity and environmental stability. The study of soil as a science has provided us with a basic understanding of the physical, chemical, and biological properties and processes essential to such a complex ecosystem.
The Soil Science Society of America (SSSA) is a professional scientific society, made up of soil scientists, educators, and consultants focused on promoting soil science, including enhancing soils topics in schools. For more information about us, contact us. SSSA is pleased to provide teachers with these Soil Essentials:
