Soil profile soil horizon is a layer parallel to the soil surface also the decaying matter, whose physical, chemical and biological characteristics different from the layers above and beneath. Horizons are defined in many cases by obvious physical features, mainly colour and texture. These may be described both in absolute terms and in terms relative to the surrounding material. The identified horizons are indicated with symbols,which are mostly used in a hierarchical way. Master horizons are indicated by capital letters. Suffixes, in form of lowercase letters and figures, further differentiate the master horizons. There are many different systems of horizon symbols in the world. No one system is more correct – as artificial constructs, their utility lies in their ability to accurately describe local conditions in a consistent manner. Due to the different definitions of the horizon symbols, the systems cannot be mixed.
