Iron Redistribution in Three Boralfs (Gray Luvisols) of Saskatchewan
Soil Science Society of America Journal, 1986Abstract 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, 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 ...

PEDOLOGICAL INVESTIGATION OF A GRAY LUVISOL DEVELOPED FROM EOLIAN SAND
Canadian Journal of Soil Science, 1982Dark 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, 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.

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.

Effects of Fluorine Deposition on the Chemistry of Acid Luvisols
International Journal of Environmental Analytical Chemistry, 1992Abstract The deposition of airborne fluorine by an aluminum smelter in Upper Austria (Central Europe) during 50 years caused a storage of fluorine in the soils up to 170 g m−2, corresponding to an annual deposition up to 3.7 g m−2. The proportion of 1:50 water extractable fluorine increased with total fluorine and ranges from 25% to 37% of the total ...

[Characteristics of references between GSCC and CST for Semi-Luvisols].
Ying yong sheng tai xue bao = The journal of applied ecology, 2006In this paper, the references between Genetic Soil Classification of China (GSCC) and the Chinese Soil Taxonomy (CST) for GSCC-Semi-Luvisols were conducted, and their quantitative and spatial distribution characteristics within CST were studied, based on the 1 : 1 M Soil Database of China, which consists of 1 : 1 M digital soil map, soils profiles ...
