In both the World Reference Base for Soil Resources (WRB) [1] and the USDA soil taxonomy, [2] a Histosol is a soil consisting primarily of organic materials. They are defined as having 40 centimetres (16 in) or more of organic soil material starting within 40 cm from the soil surface.
Histosol – organic soils, formerly called bog soils, are 1% of soils worldwide. Inceptisol – young soils. They have subsurface horizon formation but show little eluviation and illuviation. They constitute 15% of soils worldwide. Mollisol – soft, deep, dark soil formed in grasslands and some hardwood forests with very thick A horizons ...
A sapric is a subtype of a histosol [1] where virtually all of the organic material has undergone sufficient decomposition to prevent the identification of plant parts and even fecal matter. [2] [3] Muck is a sapric soil that is naturally waterlogged or is artificially drained.
Tropical peat is a type of histosol that is found in tropical latitudes, including South East Asia, Africa, and Central and South America. [2] Tropical peat mostly consists of dead organic matter from trees instead of spaghnum which are commonly found in temperate peat. [3]

Intrazonal soils have more or less well-defined soil profile characteristics that reflect the dominant influence of some resident factor of relief or parent material over the classic zonal effects of climate and vegetation.

In USDA soil taxonomy, Gelisols are subdivided into: . Histels: organic soils similar to histosols except that they have permafrost within two meters (6 ft 7 in) below ground surface.
