Andosols and soils with andic properties in the German soil taxonomy
Journal of Plant Nutrition and Soil Science, 2007AbstractThe presence of soils with andic properties on German territory has been suspected for decades and there are numerous reports of sites where they may potentially occur. Andic properties, however, are not adequately represented by the German soil‐classification system.

Occurrence and origin of soils with andic properties in Calabria (southern Italy)
Geoderma, 2014Abstract Andic-like soils, along with Andosols, have previously been reported in non-volcanic ecosystems of the coastal and mountainous areas of the Calabria region (southern Italy), but little is known about their properties, soil formation processes and volcanic source areas.

Andic properties in soils developed from nonvolcanic materials in Central Bhutan
Journal of Plant Nutrition and Soil Science, 2005A number of soils are described in the literature as having andic and spodic soil properties, but have developed in nonvolcanic and nonallophanic materials and lack typical Podzol eluvial and illuvial horizons. They cover a wide range of parent materials and different types of climate. They have always been regarded as restricted to small areas.

Andic Soil Properties of Spodosols in Nonvolcanic Materials of Southeast Alaska
Soil Science Society of America Journal, 1993Abstract Andic properties are typical of soils in volcanic materials, including those in southeast Alaska. Nonvolcanic materials, however, predominate in southeast Alaska, yet andic properties are common in Spodosols throughout the area.

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 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 ...

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).

Classification of Anthropogenic Soils with Andic Properties
Soil Science Society of America Journal, 2009On the mountainous islands of the Canary Islands (Spain), the soils on the cool and humid north face are better suited to farming than those on the hot and arid south side. A common practice is to transport soils from one side of the island to the other—as well as from midaltitude zones in the north to others lower down—to ...

Classification of Soils with Andic Properties from the Oregon Coast
Soil Science Society of America Journal, 1985Abstract Fourteen pedons from three northern Oregon coastal counties were evaluated for their chemical and physical properties for inclusion in the proposed soil order Andisol (Leamy, 1984). Seven pedons were found to meet the criteria for bulk density, aluminum solubility in ammonium oxalate (Al
