Today we are going to talk about Podzol in Soil Science. Podzol is a typical land of coniferous and boreal forests in geology. Podzol is also typical of the eucalyptus forests and heathlands of South Australia. In Western Europe it develops over Heathland and is often the result of human intervention by burning and grazing. Podzol is also preserved under the cambisols Bronze Edge Burrows in some of the landlocked British Moorlands. So let's gather a little more information about Podzol in Soil Science.
It is a sterile and highly acidic soil and which appears as white or gray ash. Podzol is found in mountainous regions and boreal zones. In Germany it is found in the Alps. And Podzol is very widespread in Scotland and is found in cold and humid climates such as under forests and in vegetation. It is also found in the eucalyptus forests of South Australia. Podzol covers 14.3% of Canada's land area. It facilitates a groundwater recharge. Podzol is also used for recreational and grazing purposes. Threats to its existence are wind erosion and sand surface mining.
Information of Features of Podzols
The main feature of Podzol is that Podzol is a sterile soil. The sand component and low moisture content make Podzol a weak soil for inclusion in farming methods. Podzol is highly recommended for fertilization where it should be used for agriculture. This soil is highly acidic as evidenced by a lower pHs. The soil of Podzol lacks critical soil nutrients like phosphate.
Podzol-type soils also experience aluminum toxicity and that hinder plant growth. This type of soil has a high C / N ratio and is related to the ratio of carbon to nitrogen in the soil. And whenever the C / N ratio is high it means that the carbon is high resulting in slow residue decomposition and nitrogen cycling in this soil.
Information about Entomology of Podzol
The word podzol is derived from the Russian language. The words he makes are pods which mean "under" and zola which means "ashes". Consequently, the word means "ash". The term podzol was coined in 1875 by Vasily Dokuchaev to describe the ashes found by Russian farmers in the process of plowing their fields. The term is given different names depending on the land classification system of that country. As a result one will find names like espodossolos, podzolic order and espodossolos used in Brazil, Canada and China respectively.
Information about Formation of Podzols
When podzol is formed, soluble metal complexes such as silicon, aluminum and iron move through the percolating water to deeper parts of the soil profile. The resulting ash-gray component forms within the eluvial horizon. Podzol and metals combine with iron and aluminum oxide to form moisture in the sub-soil. The virtual horizons found below the surface of the earth also have the movement of metal complexes and those horizons are usually black, brown or red. They are made up of organic compounds.
Characteristics of Podzols
This type of soil can occur on almost any native material but is usually obtained from Podzol from quartz-rich sands and sandstones or silt debris from magmatic rocks. If there is high rainfall on Podzol most of the Podzol soil is poor soil for agriculture due to the sandy part and consequently low levels of moisture and nutrients.
Some are drinking sandy and excessive water from Podzol. Podzol is the best agricultural use of land for grazing. Well-dried loamy varieties can be very fruitful for the crop if lime and manure are used on the podzol.
Podzol in the E horizon area is usually 4 to 8 centimeters thick and low in Fe and Al oxides and humus. This type of Podzol is formed under humid, cold and acidic conditions and is especially rich in parenteral material and sandstone, quartz. Podzol is found under the layer of organic matter in the process of decay and is usually 5 to 10 centimeters thick.
In some Podzol plus soils, the E horizon is absent. Podzol is masked by biological activity and eliminated by disruption. This type of soil with H horizon development is often classified as brown podzolic soils and also called Umbrepts or Umbrisols.
Podzolization of Podzol
Podzolization of Podzol is a complex clay formation process by which organic matter and ions of iron and aluminum are dissolved. Podzolization is released by the weathering of various minerals and forms organo-mineral complexes and Podzol is moved from the upper parts of the soil. Profile and Podzol deposited in deep parts of the soil. Through this process, the alveolar horizon becomes bleach and ash-gray in color. This process is a specific process of soil formation in Podzol soils.
This process usually occurs under forest and healthy vegetation where it is common in cold and humid climates as this environment Podzol inhibits the activity of soil microorganisms. Overall podzolization happens where the decomposition of organic matter is prevented and as a result, an acidic organic surface layer is formed. Podzol in acidic conditions under this process usually prevents the microbial degradation of organic complex agents lacking nutrients in the soil.
Geographic distribution of Podzol
The land of Podzol covers about 4,850,000 square kilometers worldwide. And Podzol is commonly found under the sclerophyllous wood plant. To some extent Podzol's soil is most common in the temperate and boreal zones of the Northern Hemisphere, but Podzol can also be found in other settings, including temperate rainforests and tropical regions. Podzols occur beneath the forests beneath Nothofagus betuloides in South America.
Information About In Different Podzol Soil Classification Systems
1. The term is used in the world reference base for land resources and in many national land classification systems.
2. The Canadian soil classification system corresponds to the term land under the Podzolic order.
3. Brazilian Podzol Soil Classification System calls them Espodossolos.
4. The USDA calls this type of soil classification and porcelain classification Spodosols.
5. The Australian land classification uses the term podosols.
