   The soil is arranged in layers or horizons during its formation. These layers or horizons are known as the soil profile. It is the vertical section of the soil that is exposed by a soil pit. The layers of soil can easily be identified by the soil colour and size of soil particles. The different layers of soil are:

   Compared to other mineral horizons (E, B, or C) in the soil profile, they are rich in organic matter, giving them a darker color. The A horizon, over time, is also a zone of loss – clays and easily dissolved compounds being leached out – and A horizons are typically more coarse (less clay) compared to underlying horizons (with the exception of an E horizon).

   What are horizons in a soil profile?

   • The various layers are known as horizons. A soil profile contains three main horizons. They are named as horizon A, horizon B and horizon C. The surface soil or that layer of soil at the top which is liable to leaching and from which some soil constituents have been removed is known as horizon A or the horizon of eluviation.

   How are mineral soil layers assigned to each horizon?

   • The assignment of mineral soil layers to each horizon is done by comparing the properties of the horizons in the field to a list of distinctive characteristics, called diagnostic properties. Table 1: Basic description of mineral soil horizons in the Canadian System of Soil Classification (Agriculture Canada Expert System on Soil Survey, 1987).

   Is a horizon a mineral layer?

   • Incorrect: The described layer is all organic. An A horizon has a strong mineral component. Incorrect: A B horizon is mineral soil and has evident soil activity such as color development, clay increase, or structure. Incorrect: A C horizon is a mineral layer and has little OM accumulation or any other soil development.

   What is soil horizon development?

   • Continued weathering and soil horizon development process leads to the development of a soil profile, the vertical display of soil horizons. The image below is of a generic, fully developed soil with all common horizons present. Many sopils do not have all horizons, but just a smaller set. At the top of the profile is the O horizon.
