Such soils can be formed from any parent soil, and are commonly found in areas where agriculture has been practised for centuries. Anthrosols can be found worldwide, though they tend to have different soil horizon
s in different regions. For example, in northwestern Europe Anthrosols commonly have Plaggic or Terric horizons, and together they cover some 500,000 hectares.

Soil horizon
A soil horizon is a specific layer in the land area that is parallel to the soil surface and possesses physical characteristics which differ from the layers above and beneath. Horizon formation is a function of a range of geological, chemical, and biological processes and occurs over long time...
