Soil biodiversity and its importance - Shadowfaxx - 01-11-2021

Soil biodiversity refers to the variety of life that lives within the soil, including bacteria, fungi, earthworms, and termites. A teaspoon of topsoil normally contains a vast range of different species and up to 6 billion microorganisms. Soil provides the ideal habitat for micro-organisms such as bacteria, fungi, as well as insects, and other organisms.

Soil is the most biologically diverse material on Earth. It contains a diverse variety of organisms which interact and contribute to many global cycles, including the carbon and nitrogen cycles.

The preservation of soil biodiversity is integral to both the environment and the agricultural industry.


Soil biodiversity is of utmost importance because organisms living within the soil:

are essential for the cycling of ecosystem nutrients
are necessary for plant growth and nutrition
improves the entry and storage of water in the soil
provides resistance to erosion
suppress pests, parasites, and disease
Assist in the capture of carbon
are vital to the world's gas exchange cycles
Aids in the breakdown of organic matter.
