Roles and Importance of Soil

Soil is a complex mixture that supports plant life and is vital to life on Earth. It serves as a medium for plant growth, modifies the atmosphere by emitting and absorbing gases, provides habitat for many organisms, purifies water, processes nutrients like carbon, and is used as an engineering medium for construction.

WHAT IS SOIL?

Soils are complex mixtures of minerals, water, air, organic matter, and countless organisms

Soil is capable of supporting plant life and is vital to life on earth.

There are seven general roles that soils play:

1. Soils serve as media for growth of all kinds of plants.


2. Soils modify the atmosphere by emitting and absorbing gases (carbon dioxide, methane,
water vapor, and the like) and dust.
3. Soils provide habitat for animals that live in the soil (such as groundhogs and mice) to
organisms (such as bacteria and fungi), that account for most of the living things on
Earth.
4. Soils purify most of the water in terrestrial systems.
5. Soils process recycled nutrients, including carbon.

6. Soils serve as engineering media for construction and building.
