Untitled
editI intend to have a major revision of this article. This is my suggested simple definition:
In soil science parent material is one or more geological deposits in which a soil has formed. Parent material is often physically or chemically altered (weathered) due to pedological processes, leading to the formation of soil horizons. In multi-layered soils, horizon boundaries often coincide boundaries between different parent materials.
The parent material forms a natural link between geology and soil science, as its meaning is relatively well understood by both professions.
Most of the definitions of geological materials further down are poor and not relevant, as they should be described under their own headings or in the geology section.
What do we think?
Math notation
editPlease. WP:MOSMATH exists.
In this article I found this:
- 2.1 * 10^5
I changed it to this:
- 2.1 × 105

What is soil science?

- This definition is from the Soil Science Society of America.
- soil - (i) The unconsolidated mineral or organic material on the immediate surface of the Earth that serves as a natural medium for the growth of land plants.
- (ii) The unconsolidated mineral or organic matter on the surface of the Earth that has been subjected to and shows effects of genetic and environmental factors of: climate (including water and temperature effects), and macro- and microorganisms, conditioned by relief, acting on parent material over a period of time. A product-soil differs from the material from which it is derived in many physical, chemical, biological, and morphological properties and characteristics.

- You may wonder what it means, but soil science is precisely what it says it is: the science of the soil, the upper layer of earth that is fundamental to all life on our planet.
