The Nature and Properties of Soils

This page has been archived and is no longer updated. Soils are dynamic and diverse natural systems that lie at the interface between earth, air, water, and life. They are critical ecosystem service providers for the sustenance of humanity. The improved conservation and management of soils is among the great challenges and opportunities we face in the 21st century. Soil is a material composed of five ingredients — minerals, soil organic matter, living organisms, gas, and water.

Log In. Soil is a living, breathing, natural entity composed of solids, liquids, and gases. Soil has five major functions:. Our focus will be on the fifth function. In this role, soil provides structural stability for plants and retains and relinquishes water and the nutrients necessary for plant growth. This distribution rarely occurs because pore space varies with soil texture and soil management. For example, tilling increases pore space, while poor drainage and compaction reduce it.

S oil, water, air, and plants are vital natural resources that help to produce food and fiber for humans. They also maintain the ecosystems on which all life on Earth ultimately depends. Soil serves as a medium for plant growth; a sink for heat, water, and chemicals; a filter for water; and a biological medium for the breakdown of wastes.

What Are Soils?

The parent material of a soil determines the original supply of those nutrient elements that are released by weathering and influences the balance between nutrient loss and retention. Organic acids and exudates produced by microorganisms and plants enhance the weathering of minerals and the release of nutrients. Nutrients may be stored in organic cycles or as ions adsorbed to clay and organic matter. Nutrients are lost mainly by leaching, both as dissolved ions and when associated with soluble organic components. Soil formation evidently affects these processes and modifies the environment at different depths as soil horizons develop.
