Theory of podzolization.
V. V. Ponomareva
The equilibrium DOC concentrations predicted by adsorption isotherms agreed to within 1 to 2 mg/L with lysimeter results. Our results suggest that coprecipitation of iron and organic matter in the upper B horizon, a process central to podzolization, largely controls the concentration of dissolved organic carbon in stream water at Hubbard Brook. Podzolization (or Podsolization) is complex soil formation process by which dissolved organic matter and ions of iron and aluminium, released through weathering of various minerals, form organo-mineral complexes (chelates) and are moved from the upper parts of Key process: podzolization.

'Podzolization' (the formation of a spodic subsurface horizon) is actually a combination of processes, including 1 'cheluviation', the movement of soluble metal-humus complexes (chelates) out of the surface lay-er(s) to greater depth, and 2 'chilluviation', the subsequent accumulation of Al- and Fe-chelates in a spodic horizon.

The classic concept of podzolization assumes the organic complexation of Al and Fe as a major factor in their mobilization and translocation into the spodic horizons (Lundström et al., ). A proposed theory of podzolization is summarized as the more or less simultaneous formation of the Bhs and Bs horizons.
Organic complexes of Al migrate downward from the O and E horizons. This paper reviews the major mechanisms proposed to explain podzolization. These include the production of organic acids that form soluble complexes with aluminium/iron thereby enhancing.
Traditionally and in theory, the following sequence of processes are postulated as major components of podzolization: acidification and chemical weathering, release of Fe and Al cations into the soil solution, mobilization and translocation of sesquioxide. Podzolization encompasses the downward migration of Al and Fe, together with organic matter, from the surface areas and their accumulation in the profile’s deep areas.
This process is characterised by a strong acidity that causes the slow development of organic matter (which releases abundant organic compounds with an acidic nature) and an extreme alteration of the mineral phase.
podzolization (podsolization) An advanced stage of leaching, podzolization is the process of removal of iron and aluminium compounds, humus, and clay minerals from the surface soil horizons by an organic leachate solution, and the deposition of some of these translocated materials in lower B horizons.
Podsolisation is an extreme form of leaching which causes the eluviation of iron and aluminium sesquioxides. The process generally occurs in areas where precipitation is greater than minerals are removed by a process known as leaching. When organic material is broken down nutrients are released, but at the same time organic acids are released.
Podzolization. Translocation of Al, Fe mediated by downward leaching following chelation with organic acids. Characteristic: incomplete decomposition of organic material. Chelation.
Podzolization theories. Two major groups of processes have been proposed to explain podzolization: (a) formation and downward transport of complexes of organic acids with Al and Fe; and (b) silicate weathering followed by downward transport of Al and Si as inorganic colloidal by: Alban, D.H., and E.C.
Berry, Effects of earthworm invasions on morphology, carbon and nitrogen of a forest soil. Applied Soil Ecology, – From top to bottom, a podzol profile consists of: a litter layer (O) - a humose mineral topsoil (Ah), which may be absent, - a bleached, eluvial layer (E) - an accumulation layer of organic matter.
The proposed role of inorganic hydroxy-aluminium-silicate sols in podzolization is also discussed. The paper is introductory to a multidisciplinary study of podzolization performed in the Nordic Countries nordic countries Subject Category: Geographic Entities see more details presented in this by: Definition of podzolization.: a process of soil formation especially in humid regions involving principally leaching of the upper layers with accumulation of material in lower layers and development of characteristic horizons specifically: the development of a podzol.

podzolization in American English. (ˌpɑdzɑlɪˈzeɪʃən ; ˌpɑdzɔlɪˈzeɪʃən) noun. a process of soil formation, esp. in cool, humid regions, in which the upper layers are leached of iron, lime, and alumina, which are then concentrated in underlying layers.
