HIGHLY ORGANIC SOIL [2 records]

Record 1 2007-04-25

English

Subject field(s)
  • Road Construction
CONT

... the Unified system is superior in detecting properties of soils which affect airport pavement performance. The primary purpose in determining the soil classification is to enable the engineer to predict probable field behaviour of soils ... the initial division of soils is based on the separation of coarse and fine-grained soils and highly organic soils ... A separate division of highly organic soils is established for materials which are not generally suitable for construction purposes.

French

Domaine(s)
  • Construction des voies de circulation
CONT

[...] le système unifié permet de mieux détecter les propriétés des sols qui influent sur les performances des chaussées d'aéroports. L'objectif principal de la classification des sols est de prédire leur comportement [...] la classification initiale comprend trois groupes : sols à gros grains, sols à grains fins et sols à forte teneur en matières organiques [...] Le groupe des «sols à forte teneur en matières organiques» correspond à des matériaux qui ne se prêtent généralement pas à la construction.

Record 2 2007-03-20

English

Subject field(s)
  • Soil Science
CONT

Peat [is a] highly organic soil, composed of partially decomposed vegetable matter.

CONT

Initially highly organic soils are less susceptible to erosion because they retain water but once saturation is reached they have poor drainage and a slow drying capacity which increases their sensitivity to impact ... Soils with a balanced mineral composition and a lower percentage of organic mater are more robust and less sensitive to impact ...

Domaine(s)
  • Science du sol
CONT

Pour éviter les conséquences d'une application excessive, ou intempestive, d'azote [il faut, entre autres,] tenir compte de la minéralisation azotée des sols à forte concentration (> 6 %) de matière organique ou qui ont reçu de grandes quantités d'engrais animal pendant plusieurs années [...]

CONT

Cette recherche a permis de conclure que la fraction disponible de sélénium est supérieure dans les sols contenant peu de matière organique alors que dans les sols à haute teneur en matière organique, le sélénium est lié à cette fraction et de plus faible mobilité.
