Soil is a medium in which plants
grow and a habitat for animals and other micro-organisms. Fertile soil is
vital for the production of food, timber and fiber, which are all essential
for human existence and providing economic prosperity.
Soil also influences the character of
our local landscapes and preserves archaeological remains.
It plays a key role in environmental
regulation such as pollution prevention, by breaking down or reducing the
impact of chemical contaminants, and for carbon storage and release that can
influence climate change through modifying the level of greenhouse gases in
the atmosphere.Soils are important in nutrient cycling and regulating water flow and flood risk reduction.
Soil is found on the uppermost layer of earth.
It is found on the lithosphere.
