Overview of Module

Soil is the foundation our natural living world depends on. It is the often-unappreciated substance of life, the dynamic material that civilization is built on, the critical-zone of the earth. Most of our food, much of our clothing (fiber), and building materials (wood, clay, bricks, etc.) are derived directly or indirectly from soils or the plants grown on soils. Soils are also a key component to the filtration of surface water before it becomes groundwater.
