Clay movement in a saline-sodic soil toposequence
In the Herrmanns sub-catchment in the Mt. Lofty Ranges (near Mt. Torrens) soil sodicity was the dominant factor in causing clay to disperse in the eroded area along the foot slopes, wheras in non-eroded areas of the mid-slopes and on the stream banks, the dispersive power of sodicity was attenuated …

Geochemical study of soil salinity in a toposequence near Riebeeck West, South Africa
… looks at the distribution of the salts along a toposequence in a subcatchment of the Berg River underlain by Malmesbury Group shale. The objectives were: to investigate salt distribution in relation to landscape topography; to identify potentially harmful trace elements associated with the …

Urea Hydrolysis in Soil Profile Toposequences: Mechanisms Relevant to Nitrogen Transport and Water Quality
… were sampled from both the A and B horizons of toposequences consisting of an agricultural field, a grassed field border, and a transitional zone adjacent to surface waters. A pH-adjustment experiment identified soil C and N as important predictors of urea hydrolysis. Analysis of microbial …

Setting the Baseline for Regeneration of Temperate Native Grassy Ecosystems in Montane Agricultural Landscapes: An Agroecological Approach to Soil Health
… and vegetation surveys were compared across a toposequence of landform elements aligned with the contours of the site. This study provides a detailed holistic understanding of the case study site's current soil and native vegetation health. Soils were classified as red dermosols on the crest, …

Ground-based hyperspectral and spectro-directional reflectance characterization of Arctic tundra vegetation communities : field spectroscopy and field spectro-goniometry of Siberian and Alaskan tundra in preparation of the EnMAP satellite mission
… gradients (regional climate, soil pH, toposequence, and soil moisture) show that the different plant communities can be distinguished by their nadir-view reflectance spectra. The results especially reveal separation possibilities between the different tundra vegetation communities in …

Local variability in early Oligocene paleosols as a result of ancient soil catenary processes, Brule Formation, Toadstool Park, Nebraska
Paleopedology is often employed in paleoenvironmental reconstructions because the features of paleosols are affected by changes in climate, ecology, topography, and lithology over time. These changes cause small-scale variations in the morphology and apparent development of paleosols and influence …

Restructuration géomorphopédologique de la légende de la Carte des Sols de la Belgique - Application en Région limoneuse
Actuellement, la légende de la Carte des Sols de la Belgique ne permet pas d'appréhender les liens existant entre les sols, et la relation entre ces derniers et leur environnement, principalement le relief et la lithologie, n'est pas exprimée de façon explicite. De plus, de nombreuses informations …
