Students learn about the value of soil as a natural resource (regulates water, sustains plant and animal life, filters pollutants, cycles nutrients and supports structures). Then explore the importance of having/maintaining healthy soil. They will explore how different individuals describe healthy soil (to an agriculturalist means highly productive land that sustains or enhances productivity therefore enhancing profits; to consumer it means plentiful, healthy and inexpensive food for present and future generations; to environmentalist it means functioning at its potential in an ecosystem with respect to biodiversity, water quality, nutrient cycling, and biomass production).
