Most soils have three major horizons -- the surface horizon (A), the subsoil (B), and the substratum (C). Some soils have an organic horizon (O) on the surface, but this horizon can also be buried. The master horizon, E, is used for subsurface horizons that have a significant loss of minerals (eluviation).The layers of soil can easily be identified by the soil colour and size of soil particles. The different layers of soil are: Topsoil. Subsoil.
Loam is the best soil type for construction due to its ideal combination of silt, sand, and clay. It combines the best of all their qualities into the ideal balance for supporting a foundation. Loam generally does not shift, expand, or shrink drastically and handles the presence of water very well
1. The layers of soil can easily be identified by the soil colour and size of soil particles.
The soil profile has five layers:
1) O horizon;
2) A horizon;
3) B horizon, or subsoil; and
4) C horizon, or soil base
5. R horizon
