Spatial distribution of hexazinone and metabolites in a luvisolic soil
Journal of Environmental Science and Health, Part B, 1992Abstract The spatial distribution of hexazinone and two primary metabolites were measured in forest soil for two years following the aerial application of a granular formulation, PRONONE 10G, in northern Alberta. Residues were quantified using solid‐phase extraction and capillary gas chromatography. Initial deposition rates of two hexazinone treatments

Distribution and possible immobilization of lead in a forest soil (Luvisol) profile*
Environmental Geochemistry and Health, 2005Geochemical analyses using a sequential extraction method and lead adsorption studies were carried out in order to characterize the distribution and adsorption of lead on each genetic horizon of a Luvisol profile developed on a pelagic clayey aleurolite. Clay illuviation is the most important pedogenic process in the profile studied.

THE NATURE OF MERCURY IN CHERNOZEMIC AND LUVISOLIC SOILS IN ALBERTA
Canadian Journal of Soil Science, 1976Contents of mercury in surface soil horizons of Chernozemic soils from Alberta were considerably lower than contents in respective C horizons. For eluviated soils, highest contents of mercury were found in B horizons, with lowest levels in A horizons. Results for content of mercury in particle-size separates together with profile distribution patterns

THE VALUE OF ANNUAL SOIL TESTING ON LUVISOLIC SOILS
Canadian Journal of Soil Science, 1975For Luvisolic soils of west central Alberta, repeated annual testing of soils for available N and P appears to be very worthwhile. The test for N appears to be essential for cereal crops following a grass–legume hay mixture in a crop rotation. Tests for available K in the Breton Plot soils demonstrate high levels of this nutrient, and repeated annual ...

MICROMORPHOLOGY OF THREE GRAY LUVISOLS IN EAST-CENTRAL SASKATCHEWAN
Canadian Journal of Soil Science, 1985Micromorphology of three Gray Luvisolic soils under Boreal Forests occurring on late Wisconsinan age glacial till were studied. Profiles 1 and 2 occurred on loam with 8–10% carbonates; Profile 3 on clay loam till with 58% carbonates. The presence of various fecal pellets shows the importance of soil fauna in the decomposition of litter and the ...

Main Soil Features of the Luvisols in Bulgaria
2022The article deals with the Luvisols soil type, which is spread in all areas in Bulgaria. It is very important for national agriculture and forestry. This soil type occupies vast areas in the hilly and low-mountainous territories of the southern parts of Danubian plain, the Fore-Balkan area and southern Bulgaria.

Visible – NIR reflectance for evaluation of luvisols and phaeozems
2015Near infrared spectra of soils with differences in soil colour, organic matter and clay mineral content showed differences in the spectral region from 700 to 1700 nm. The objective of the present study was to describe the information content of soil vis-NIR spectra of two soil types Luvisols and Phaeozems from Romania to assist soil surveys.

Impact of sedimentary processes and paleopedogenesis on Holocene Luvisol formation
Zeitschrift für Geomorphologie, Supplementary Issues, 2012stacking of periglacial layers: A differentiation of eluvial (E-) and illuvial (Bt-) horizon is already developed within the upper layer. The intermediate layer carries the main argillic horizon of those profi les whereas the within the upper layer. The intermediate layer carries the main argillic horizon of those profi les whereas the basal layer is ...

A comparison of luvisolic soils from three regions in Canada
Geoderma, 1972Abstract Luvisolic soils (Alfisols) developed in calcareous glacial till in cold continental subhumid, moderately warm continental humid and moderately cool perhumid regions of Canada were compared. The properties and degrees of development of the soils could be related mainly to climatic and parent material factors, but also to organisms.
