Cambic Horizon
Cambic horizon (''Latin: Cambiare, to change'') is a diagnostic sub-surface Soil horizon, horizon of a soil experiencing pedogenic change. Development is minimal and it is cambic if it does not meet the Taxonomic requirements to classify in another Soil horizon, horizon. Properties There are key characteristics that determine a layer of soils classification. Cambic horizons do not consist of Illuvium, appreciable illuviated material such as clay, organic carbon, iron, and Aluminium, aluminum Oxyhydroxide, oxyhydroxides, Carbonate rock, carbonate, gypsum, or Soluble salt, soluble salts. These horizons must have a non-sandy texture and occur in poorly drained soils. The particles size must be as finer or finer than Loam, loamy fine sand or very fine sand. Classification Cambic horizons are found most in Mollisol, Mollisols and Inceptisol, Inceptisols, but can also be found in Andisol, Andisols where its designation is Bw or Bg in all three. Cambic horizons are designated as Bss o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soil Horizon
A soil horizon is a layer parallel to the soil surface whose physical, chemical and biological characteristics differ 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 (particle size distribution for texture, for instance) and in terms relative to the surrounding material, i.e. 'coarser' or 'sandier' than the horizons above and below. The identified horizons are indicated with symbols, which are mostly used in a hierarchical way. Master horizons (main 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 sym ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
