The Unified Soil Classification System (USCS) is a soil classification system used in engineering and geology to describe the texture and grain size of a soil. The classification system can be applied to most unconsolidated materials, and is represented by a two-letter symbol. Each letter is described below (with the exception of Pt): If the ...
Topsoil is composed of mineral particles and organic matter and usually extends to a depth of 5-10 inches (13–25 cm). Together these make a substrate capable of holding water and air which encourages biological activity. There are generally a high concentration of roots in topsoil since this is where plants obtain most of their vital nutrients.
A taxonomy is an arrangement in a systematic manner; the USDA soil taxonomy has six levels of classification.

In the United States, over 19,000 soil series have been identified. [1] The percentages of land area (in the US and associated territories, etc.) occupied by soils of the twelve orders have been estimated [1] as: Alfisols and Inceptisols occur widely in the US, but the circumstances of their occurrence would be difficult to characterize briefly.
