Anthrosols

In the group of the World Reference Base Anthrosols for Soil Resources divided all those soil types that have arisen under anthropogenic influence.

Among the anthropogenic influences include the introduction of organic material or waste, irrigation, or special processing. The source rock plays in the Anthrosolen, unlike other soil classifications, a very subordinate role.

Anthrosols and their dissemination

Depending on determining use different anthrosol types are distinguished:

  • Anthrosol with Plagge horizon ( plaggic horizon ) in areas with prolonged arable farming using heavy equipment, so mainly in North-West Europe
  • Anthrosol with embossed by irrigation horizon ( irragric horizon ) in areas with intensive irrigation, such as Mesopotamia, in parts of India and often in oases.
  • Anthrosol entstandenem with entstandenem by agriculture under water impoundment underbody ( hydragric horizon ) and by plowing under partial water coverage topsoil ( anthraquic horizon ). Primarily in areas of wet rice cultivation, especially China and Südsüdostasien
  • Anthrosol with garden horizon ( hortic horizon ) with quasi- global distribution, in areas with a long history of settlement. It is characterized by deep -reaching plowing, fertilization through ongoing waste and other organic matter from urban areas ( kitchen waste, compost or manure )
  • Anthrosol with mineral Acker-/Gartenerde-Horizont ( terric horizon ) in areas of intensive and long-lasting soil improvement by adding minerals such as lime ( Kalkmelioration, especially England), mineral-rich muds and coastal sands. They are characterized by strong biological activity of, are neutral to slightly alkaline ( pH of soil water usually > 7) and often contain free lime. Characteristic is the long lasting material created by adding soil increase and an appreciable proportion of small-sized artifacts such as brick or ceramic.

Local names

Local names for special Anthrosols include Terra Preta do Indio for a Hortic anthrosol who finds his main distribution area in the Amazon basin of Brazil. Paddy Soil is the English name for the hydragric anthrosol. This is one arising under wet rice cultivation " anthropogenically - hydromorphic Pseudogley ".
