Subject field(s)
  • Soil Science
CONT

Histosols are an order of soils which include the organic soils (bog soils) as well as some of the half-bog soils. These soils have developed in a water-saturated environment and contain at a minimum 20% organic matter if the clay content is low, and 30% if the clay content is more than 50%. These soils are among the most productive, especially for vegetable crops.

OBS

Histosols are formed because the production of organic debris exceeds its decay; the accumulated dead plant material is only slightly decomposed due to varying combinations of waterlogging (and resulting anaerobic conditions), low temperatures and severe acidity.

French

Domaine(s)
  • Science du sol
CONT

Histosol. Peu différencié; faible aptitude au drainage; plus haute teneur en carbone organique de tous les types de sols.

CONT

Quels sont les processus qui gouvernent les transformations de la matière organique lors de la formation d'un histosol?

OBS

histosol : terme extrait du «Glossaire de l’agriculture» et reproduit avec l’autorisation de l’Organisation de coopération et de développement économiques.

DEF

Soil consisting mainly of organic matter, such as peat or muck.

OBS

OBS

[For example :] Histosol.

Record 3 2003-09-02

English

Subject field(s)
  • Soil Science
  • Geology
DEF

Organic soil derived from the decomposition of peat, usually in an area subject to periodic overflow by silty waters, and containing 20 percent or more of mineral material.

DEF

saprist: The suborder of the Histosols that consists almost completely of decomposed plant remains.

CONT

A Histosol is a soil where more than half of the upper 80 cm is organic... Suborders of Histosols are defined on the basis of the degree of decomposition of organic material. The suborders are fibrist, saprist, and hemist.... Fibrist is soil where less than one-third is decomposed and more than two-thirds is identifiable; Saprist is soil where two-thirds or more is decomposed material and less that one-third identifiable plant fiber; Hemist is soil somewhere in-between saprist and fibrist.

OBS

Mucky peat and peaty muck are terms used to describe increasing stages of decomposition between peat and muck.

OBS

muck: In modern use distinguished from peat by being more thoroughly decomposed (and usually darker in colour) and having a higher mineral content.

OBS

Muck is another name for peat, especially when the material is employed as a manure.

OBS

Peat has been defined as containing over 65% of organic matter and Muck as containing from 25% to 65%. It does not appear desirable to place such definite limits of composition but rather to base the distinction mainly on the degree of decomposition and secondarily on the content of mineral material.

OBS

Not to be confused with "organic soil", a general term applied for a soil or a soil horizon that consists of primarily of organic matter (or contains at least 30% organic matter), such as peat soils, muck soils, and peaty soil layers. (See also that record).

Key term(s)
  • muck land

French

Domaine(s)
  • Science du sol
  • Géologie
DEF

terre tourbeuse : Matière organique partiellement décomposée, dans laquelle les restes des plantes ne sont pas discernables, qui se forme dans des conditions humides anaérobies et qui est mélangée avec des matières minérales.

DEF

tourbe évoluée : matière organique bien décomposée et humifiée provenant de l'évolution, en milieu partiellement aérobie, de la partie supérieure d'une tourbe drainée.

OBS

tourbe évoluée : contient généralement plus de matière minérale, et est généralement plus foncée que la tourbe; on n'y reconnaît pas les débris des plantes qui ont participé à sa formation; en Amérique du Nord on appelle abusivement de la même façon un sol comportant de 20 à 50 pour cent de matière organique.

CONT

La terre tourbeuse humide caractérise la tourbière. Celle-ci est composée de matières organiques, de plantes mortes, décomposées et compactées avec les années, formant une couche détrempée, chargée de carbone, pouvant atteindre six mètres d'épaisseur.

OBS

Les termes tourbe organique ([en anglais : «mucky peat») et sol organique tourbeux ([en anglais :] «peaty muck») désignent des stades croissants de décomposition entre la tourbe et le sol organique.

Spanish

Campo(s) temático(s)

DEF

Materia orgánica parcialmente descompuesta en la que los restos de las plantas no son discernibles, que se forma en condiciones húmedas anaerobias y que está mezclada con materias minerales.
