Andosols and soils with andic properties in the German soil taxonomy

Journal of Plant Nutrition and Soil Science, 2007
AbstractThe 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.

Andic properties in soils developed from nonvolcanic materials in Central Bhutan

Journal of Plant Nutrition and Soil Science, 2005
A 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.

PHOSPHATE AND SULFATE RETENTION BY NONVOLCANIC SOILS WITH ANDIC PROPERTIES

Soil Science, 2001
Soils with andic properties have a high anion retention capacity, which is mainly related to the large amounts of active Al and Fe compounds that they contain. The phosphate (PO 4 ) and sulfate (SO 4 ) sorption capacity of soils with andic properties from Galicia, NW Spain, was investigated.

Andic Soil Properties of Spodosols in Nonvolcanic Materials of Southeast Alaska

Soil Science Society of America Journal, 1993
Abstract 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.

Classification of anthrosols with vitric/andic properties derived from lignite ash

Geoderma, 2005
To test the applicability of the Soil Reference Base of Soil Resources (ISSS/ISRIC/FAO, 1998. World Reference Base for Soil Resources, World Soil Resources Report 84, FAO, Rome) for soils derived from anthropogenic substrates, soils developed on lignite ashes in Germany which have some similarities with andosols were compared with natural volcanic ...

ANDIC SOILS OF THE INLAND PACIFIC NORTHWEST, USA: PROPERTIES AND ECOLOGICAL SIGNIFICANCE

Soil Science, 2005
Holocene tephra from the cataclysmic eruption of Mount Mazama in southwestern Oregon is an important component of many soils east of Cascade Mountains in the Pacific Northwest region. This article examines ecologically important properties of these tephra-influenced soils.

Occurrence and origin of soils with andic properties in Calabria (southern Italy)

Geoderma, 2014
Abstract 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.

Expression of andic and spodic properties in tephra-influenced soils of northern Idaho, USA

Geoderma, 1993
Abstract Tephra from Mount Mazama (Crater Lake) has strongly influenced genesis and morphology of forest soils in the Selkirk Mountains of northern Idaho. Characteristics associated with Andisols and their intergrades are common in soils throughout the area. In addition, tephra-influenced soils of the higher elevations exhibit properties of Spodosols

Expression of andic properties in soils from Galicia (NW Spain) under forest and agricultural use

European Journal of Soil Science, 2004
Summary The organic matter (OM) of soils with andic properties has long been considered highly stable because of the presence of Al–humus complexes and sorption of organic ligands onto amorphous compounds. In this study, we characterized soils under different land use regimes located within an amphibolitic massif ...

Dielectric properties of a tilled sandy volcanic-vesuvian soil with moderate andic features

Soil and Tillage Research, 2013
The apparent dielectric constant, e, of many agricultural soils, measurable with the Time Domain Reflectometry (TDR) method, may be used to estimate soil water content, u, with the Topp's empirical model. However, organic soils and those of volcanic origin do not obey this model, which has been termed ''universal''.
