Properties, classification and genesis of selected pedons in the central interior of British Columbia, Canada
Dans cette étude, les AA. déterminent les caractéristiques physiques, chimiques et morphologiques de pédons sélectionnés. Ils classent les sols selon le système canadien de classification des sols (1987), et selon les Clés pour la taxonomie des sols

Effet de la succession de différentes affectations sur les propriétés chimiques de pédons en Fagne de Chimay (Belgique)

Terra Rossa catenas in Wisconsin, USA

The AA. have sampled 144 pedons of 16 catenas with different slope aspects and curvatures in a 70 km2 area in Wisconsin. Half of all the pedons had a red clay subsoil. The thickness of the red clay ranged from 4 cm to 60 cm with an average thickness

Four pedons from the alluvial plain of Drama (NE Greece) were investigated in order to provide detailed information on their morphology, chemical, physical and mineralogical properties, classification and genesis. Smectite (montmorillonite
) is the dominant clay mineral and was mainly inherited from the parent sediments and by neoformation. The pedons located in the highest points of the alluvial plain were classified as Chromic Haploxererts and those in the lowest landscape were classified as Typic

This study provides characterization data, and examines spatio-geomorphic variability, for some pedons that have developed on these debris aprons under a warm to temperate humid climate. It also compares the pedons to those derived from nearby

representative pedons of the benchmark upland soil, the Norfolk series, with depth-to-argillic of the Norfolk series at two baseline sites.

This paper presents the main features of an altitudinal sequence. They were determined from mapping soils on a late cenozoic volcanic plateau west-southwest of Lassen Peak, and from the analyses of 27 pedons sampled from 270 to 2 030 m above sea

A sequence of approximately 75 strand plain beach ridges located along the northern shore of Lake Michigan, USA, was used to explore rates of soil development in the initial stages of podzolisation. Well drained pedons were sampled on 24

A numerical index of soil development, the POD Index, was developed and applied to 723 pedons of United States soils that either exhibit or are developing, podzol (spodosol) morphology. The index is determined solely from morphologic (field

Impact relatif de la géologie et de la topographie sur les caractéristiques des profils en résultant, sur les propriétés chimiques et minéralogiques et la classification des profils de sols, à partir de l'étude de 8 pedons dans divers sites

This study examines : 1) the morphology of mound, pit, and undisturbed pedons| 2) the effect of pit/mound microtopography on soil water content and soil freezing| 3) the spatial and temporal variability of pedogenesis as indicated by cations of Fe

Etude pédologique et géochimique de six pédons dans le sud-ouest du Nigéria. Présentation des résultats des études de terrain (nombre et profondeurs des horizons A et B, couleur du sol et texture) et des études de laboratoire (pourcentage de matière

typifying pedons. In so doing, they hope to assist those who develop and use chronofunctions by heightening their awareness of the potential variation in pedologic development and weathering across geomorphic surfaces.

Three Harney pedons were studied with different precipitation regimes in Kansas. The aim was to : examine the morphological, chemical, physical and mineralogical characteristics of Harney soils formed in loess; determine the clay mineral

, derived from till parent material with an un-drained closed depression, was selected in central Ohio. Pedons were collected from the Gahanna Woods Park. All soil samples were analyzed for selected physical and chemical properties. It is highlighted
(granular). Soil total N was correlated with that of SOC across the toposequence and within pedons.

. Le pedon est une unité diagnostique plus grande. En tant qu'unité bidimensionnelle, il caractérise le type et le sous-type du sol. Dans les 3 dimensions il est la plus petite unité de sol, cartographique et homogène, en groupe il forme une zone de sol
élémentaire (EOG). La séquence des pedons ou l'EOG forment la catena le plus grand taxon qui distingue la famille de sol RG dans la classification typologique des sols, la combinaison des sols KC dans la taxonomie cartographique et la micro-région la plus

Alfisols cover 18% of the surface of the NE edge of the Garrat massif (SE of Barcelona, Catalonia). Most of these are Mediterranean red soils. Some representative pedons, especially over Mesozoic limestones, are discussed in this paper. Climate
