spodic horizon is a subsurface horizon underlying an O, A, Ap, or E horizon. A spodic horizon must have 85 percent or more “spodic materials” in a layer 2.5 cm or more thick that is not part …

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 …

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 …

For soil science students and soil survey practitioners who want more than a simple definition, this glossary offers additional information for a deeper understanding. A wide array of terms are …

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 …

Spodosols are divided into the suborders, Aquods (wet), Cryod (cold), Humods (high organic matter), and Orthods (ordinary spodosols). A black, reddish-brown to dark-brown subsoil …

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 …

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 …

Spodosols are characterized by high acidity, and have a subsoil accumulation of organic matter, along with aluminum and iron oxides, called a spodic horizon.
