Abstract Volcanic soils show peculiar characteristics related to the presence of poorly ordered crystalline minerals. These minerals are highly sensitive to specific spectral bands in the visible and near-infrared (Vis-NIR) regions and could be used to establish important relationships between andic properties and soil classification.

Abstract An important criterion used to determine andic properties in World Reference Base is Al + ½ Fe content (by ammonium oxalate) equal to 2% or more. Experiments have shown however that the acid–ammonium oxalate-extractable Fe (Feox) value often does not only express the amorphous or short-range-order (SRO) Fe-constituents, typical for andic ...

Significance of loess addition in relation to andic soil properties of volcanic ash soils
Soil Science and Plant Nutrition, 1993Abstract Sixty two soil-loess combinations using 2 loess samples from China and 6 volcanic ash soils from Japan were studied to determine the contribution of loess to some of the chemical properties of Andisols. Prior to mixing- the loess with the soil samples, CaCO3 was removed by pretreating the loess samples with a sodium acetate buffer solution ...

Abstract In volcanic soils of the Solofrana valley (south-western Italy), contamination by Cr and Cu occurs as a consequence of agricultural practices and surface deposition of polluted river sediments by periodic floods. In this study, the metal distribution in micromorphological features and clay fractions ( − 1 ).

In volcanic regions, soils containing both noncrystalline materials and layer silicates are widespread. Although the respective contribution of these components to soil physical behaviours is difficult to quantify, it is an important issue in the Canary Islands, where Andisols and andic soils are transported to the low lands for cultivation (‘‘sorriba’’

Abstract Relationships between charge variation and diagnostic soil properties were studied in Andisols and andic subgroups of Inceptisols and Ultisols. Charge variation was calculated as the difference between “field” or actual cation exchange capacity (CECa), and potential CEC (1M NH4OAc, pH 7).

On typologically relevant properties of Andic verbal grammatical systems
Voprosy JazykoznanijaDespite the fact that Andic languages ( East Caucasian) are widely recognised as agglutinating, their verbal systems barely demonstrate any agglutinating properties. The most important characteristics of these systems are the incomplete orthogonality of grammatical categories and the related properties of semantic non-additivity or morphological ...

Hydropedological importance of calcic diagnostic horizons and andic diagnostic properties
2012Diagnostic horizons and diagnostic properties have a fundamental importance for soil classification (e.g. WRB, Soil Taxonomy) and also for applications in pedology (e.g. land evaluation). Then soil databases (and soil maps) typically contain information regarding the presence and thickness of diagnostic horizons.

The significant spatial variability of soil cover results from the diverse impacts of different soil-forming factors. This book presents pedovariability in the form of a collection of soil sequences typical of particular landscape types. The fifth part of the Soil Sequences Atlas contains description of 73 pedons (with soil profile photo, description ...
