Spodosols - Natural Resources Conservation Service
网页Spodosols formed from weathering processes that strip organic matter combined with aluminum (with or without iron) from the surface layer and deposit them in the subsoil. The central concept of Spodosols is that of soils in which amorphous mixtures of organic matter and aluminum, with or without iron, have accumulated.
Spodosol | Acidic, Sandy & Clay | Britannica
网页Spodosols are ashy gray, acidic soils with a strongly leached surface layer. Their suitability for cultivation is limited to acid-tolerant crops and orchards, provided that sufficient lime and fertilizer are applied.
Spodosols | Soil & Water Systems | University of Idaho
网页Spodosols (from Greek spodos, "wood ash") are acid soils characterized by a subsurface accumulation of humus that is complexed with Al and Fe. These photogenic soils typically form in coarse-textured parent material and have a light-colored E horizon overlying a reddish-brown spodic horizon.
Podzol - Wikipedia
网页In soil science, podzols, also known as podosols, spodosols, or espodossolos, are the typical soils of coniferous or boreal forests and also the typical soils of eucalypt forests and heathlands in southern Australia. In Western Europe, podzols develop on heathland, which is often a construct of human interference through grazing and burning.
Spodosol - an overview | ScienceDirect Topics
网页Spodosols are characterized by a heavily leached surface mineral horizon and a deeper accumulation of Al and Fe-rich organomineral complexes. Spodosols form under coniferous or mixed forests in relatively cool regions with substantial hydrologic leaching, particularly at the northern borders of the biome in the Northern Hemisphere.

网页2015年1月1日 · These podzolic soils are Spodosols, Ultisols, Inceptisols without placic horizon, and Inceptisols with placic horizon. In this chapter, two representative types of Spodosols in Taiwan are introduced as Typic Haplorthods and Ultic Haplorthods, while the other podzolic soils are discussed in the other chapters.

Spodosols - Michigan State University
网页Spodosols are acid soils characterized by a subsurface accumulation of humus and Al & Fe oxides. These soils are very photogenic and typically have a light-colored E horizon overlying a reddish-brown spodic horizon. Spodosols often occur under coniferous forest in cool, moist climates.
