A fascinating but little-understood aspect of soil is its biological component. More living organisms occur in soil than in all other ecosystems combined. The living portion of soil is a diverse and dynamic collection of organisms, from types that you can easily see with an unaided eye down to creatures that you can observe only by using a high-powered microscope.

The primary activity of soil organisms is to break down carbon-containing material (organic matter). This function is essential because without decomposition, the earth would be littered with organic refuge. But soil organisms do more than just dispose of refuse. They:

. Improve soil aggregation, which influences water movement and aeration;

. Enhance nutrient levels;

. Develop soil organic matter;

. Form symbiotic relationships with plants; and

. Break down applied materials.
