Planosols are subject to water saturation in wet periods because of stagnation of rain or floodwater. He did not initiate the use of the term Podzol, but he simply used the vernacular of his time. The still deeper illuvial horizon is commonly dark brown and irregular in depth.

  • Podzols – Land Use Impacts on Soil Quality
  • Podzolic soil pedology

  • The Canadian system of soil classification matches Podzols with soils under the Podzolic.


    Podzolic soil, podzolic also spelled podsolic, also called lessivé soil, soil usually forming in a broadleaf forest and characterized by moderate leaching, which. The name of the “Podzol” soil type has its roots in the Russian words “pod”, which means “under” and “zola,” meaning “ash” (Ponomareva, ). Therefore, the.
    A cuesta is a tilted, low-angle dipping sequence of resistant sedimentary rocks, which stand out in the landscape as a non-eroded ridge.

    In such areas, a complex mosaic of Umbrisols, Phaeozems and Anthrosols can be found. Strongly podzolized soils with a very thick albic eluviation horizon occur on poor quartz sands, notably in the humid tropics. Stagnic properties are present in many Albeluvisols; gleyic properties are much less common.

    In those environments either Gleysols or Organic soils develop. Luvisols on steep slopes require erosion control measures.

    The low nutrient status, low level of available moisture and low soil-pH make Podzols unattractive soils for arable farming. Most Podzols have a surface litter layer an H-horizon that is 1 to 5 cm thick, loose and spongy, and grades into an Ah-horizon with partly humified organic matter.

    In the more temperate part of the distribution belt, the eluvial horizon may meet the diagnostic requirements of a cambic horizon.

    Periodic saturation of the surface soil and reduction of iron compounds enhanced by dissolved organic compounds cause strong bleaching of the eluvial horizon.

    The length of the Podzolic development can vary, but on average most Podzols take between 3, and 10, years to develop. Strongly leached Ferralsols, although very low in cations and with a soil-pH of 4.

    It occurs usually on spodosols or podzols, strongly weathered siliceous soils developed .

    Podzols are soils with an ash-grey subsurface horizon, bleached by organic acids, `Podzol' is used in most national and international soil classification systems; distribution of tropical Podzols is not known; important occurrences are found.
    Paddy fields should be allowed to dry out at least once a year to prevent or minimize microelement deficiencies or toxicity associated with prolonged soil reduction.

    This causes an apparent solubility of largely hydrophobic units.

    The sandier the soil material is, the more pronounced the albeluvic tonguing. Article History. Canadian Journal of Soil Science. In parts of the Central Highlands there are reddish brown latosolic soils partially laterized soils or immature brown loams clayey loams.

    Luvisols tend to become richer in swelling and shrinking clays towards the dry end of their climatic zone.

    Many Albeluvisols in forest areas in Western Europe, where little or no cattle grazing is practised, have a fragipan overlapping with the argic horizon.

    This penetration of clay and iron-depleted material into the underlying horizon is distinctly different from the tonguing in some Chernozems or Podzols. Planting of perennial crops and bench or contour terracing offer possibilities for permanent agriculture on gentler slopes. It is found under a layer of organic material in the process of decompositionwhich is usually 5 to 10 centimetres 1. Types of soil.

    1. Arctic tundra vegetation with herbs and dwarf shrubs colonised large parts of North America and Northwest Europe. The clay turns into hydrogen clay, which converts to aluminium-magnesium clay as adsorbed hydrogen ions are replaced by aluminium and basic cations dissolved from the clay structure.

    2. In the colder part of the distribution belt, a thin layer with all features of a spodic horizon may be found in the upper part of the eluvial horizon.
