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 - 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.
Podzol - Wikipedia
网页It is formed under moist, cool and acidic conditions, especially where the parent material, such as granite or sandstone, is rich in quartz. It is found under a layer of organic material in the process of decomposition, which is usually 5 to 10 centimetres (2.0 to 3.9 in) thick.
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.
Spodosols - Michigan State University
网页The soils form under forest, usually mixed forest types (maple, pine, hemlock, birch). They are useful for forestry and recreation. Spodosols are acid soils characterized by a subsurface accumulation of humus and Al & Fe oxides.

网页2024年5月24日 · Spodosol. Spodosol soil is commonly found in cool, moist environments under coniferous forest vegetation. Surface litter composed of pine needles breaks down in the presence of water to form a weak organic acid. Acidic soil water removes base ions in solution to create an acidic soil.
5.8 - Spodosols | Soil Genesis and Development, Lesson 5 - Soil ...
网页Spodosols commonly form in sandy parent materials under coniferous forest vegetation. As a consequence of their coarse texture, they have a high leaching potential. Spodosols are characterized by high acidity, and have a subsoil accumulation of organic matter, along with aluminum and iron oxides, called a spodic horizon.
