Luvisolic soils of Canada: Genesis, distribution, and classification

Canadian Journal of Soil Science, 2011
Lavkulich, L. M. and Arocena, J. M. 2011. Luvisols of Canada: Genesis, distribution, and classification. Can. J. Soil Sci. 91: 781–806. Luvisols link the soil continuum on the Quaternary landscapes. These soils are developed from parent materials rich in Ca and Mg in a relatively humid climate.

Phosphorus characteristics correlate with soil fertility of albic luvisols

Plant and Soil, 2005
The information on phosphorus (P) characteristics of albic luvisols and their effect on plant P uptake is limited. Twelve soils representing typical albic luvisols were collected from farmland of four regions in northeast China, each with various levels of soil fertility.

Iron Redistribution in Three Boralfs (Gray Luvisols) of Saskatchewan

Soil Science Society of America Journal, 1986
Abstract The transformation and translocation of Fe in three Boralfs (Gray Luvisols) were studied in relation to the Fe contained within silicate minerals and that existing in oxide forms. Quantitative evaluations of the Fe redistribution using a quartz index technique provided conclusive evidence that losses of Fe from E horizons and

THE VALUE OF ANNUAL SOIL TESTING ON LUVISOLIC SOILS

Canadian Journal of Soil Science, 1975
For 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 ...

PEDOLOGICAL INVESTIGATION OF A GRAY LUVISOL DEVELOPED FROM EOLIAN SAND

Canadian Journal of Soil Science, 1982
Dark Gray Luvisols developed from dune sand parent material near Devon, Alberta, have Ae horizons of unusually high chromas and dark values when moist, and B horizons with very hard massive structure when dry. Micromorphological examination shows the high chromas in the Ae reflect the presence of organic, and to a lesser extent, matrix coatings on f ...

A comparison of luvisolic soils from three regions in Canada

Geoderma, 1972
Abstract 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.

Main Soil Features of the Luvisols in Bulgaria

2022
The 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

2015
Near 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.
