WikiProject Soil is a project to organize and improve articles related to soil.
Articles maintained by this WikiProject are grouped in Category:WikiProject Soil by using the {{WikiProject Soil}} template.
Soil is defined as:
- The "material that forms at the interface of the atmosphere and the lithosphere which is capable of supporting plant growth" (White 1997).[1]
- A critically important component of the earth's biosphere maintaining local, regional, and world-wide environmental quality (Doran & Parkin, 1994).[2]
- The "different forms of earth on the surface of the rocks, formed by the breaking down or weathering of rocks."[3]
- A "natural body composed of solids (minerals and organic matter), liquid, and gases that occurs on the land surface, occupies space, and is characterized by one or both of the following: horizons, or layers, that are distinguishable from the initial material as a result of additions, losses, transfers, and transformations of energy and matter or the ability to support rooted plants in a natural environment."[4]
- The granular material on the surface of other celestial bodies. Lunar soil and Martian soil are terms in general use that fit within the context of this project.
