What is Laterization process?
laterization. [ lăt′ə-rĭ-zā′shən ] The weathering process by which soils and rocks are depleted of soluble substances, such as silica-rich and alkaline components and enriched with insoluble substances, such as hydrated aluminum and iron oxides.
What is the process of formation of laterite soil?
Laterite soil is formed by chemical weathering that causes leaching of the parent sedimentary rocks, which is known as ‘lateralization’.
What is Humification and how does it help in soil formation?
Soil formation takes place by weathering of rocks, humification of plant remains and laterisation. In the process of humification, humus is produced by the decomposition of plant twigs, wood, etc. Humification affects soil quality, its colour and texture. Black or dark brown coloured soil is rich in humus.
What is laterite soil also known as?
Another name for residual soil is laterite soil. The main cause behind weathering in residual soils is chemicals (Fig. 1.5).
What are the differences between podzolization and Laterization?
Laterization is inverse process to that of podzolization i.e. the process that removes silica, instead of sesquioxides from the upper layers and thereby leaving sesquioxides to concentrate in the solum.
Is leaching and Laterization same?
i. The first step is decomposition which involves the breakdown of minerals resulting in the release of constituent elements like calcium oxide, magnesium oxide, etc. ii. The second step is laterization which involves leaching (loss of soluble substances and colloids from the topmost layer of soil).
What is lateralization of soil?
Laterization is a prolonged process of chemical weathering of rocks leading to the formation of soil. It produces a variation in the thickness, grade, chemistry and ore mineralogy of the rock creating soil particles. Thus the correct answer is option C.
What is the name of soil formed by intense leaching?
Laterite soil
Laterite soil is the result of intense leaching due to heavy rain.
What is humification process?
Humification is a process of formation of humic substances (organic matter that has reached maturity) decomposed from plant remains.
What is black soil called?
black soils known locally as regur. After those the alluvial soil is the third most-common type. Also significant are the desert soils of Rajasthan, the saline soils in Gujarat, southern Rajasthan, and some coastal areas, and the mountain soils of the Himalayas.
What is lateralization and podzolization?
Podzolization is a soil formation process in which dissolved organic matter and ions of iron and aluminum, released through weathering of various minerals and are moved from the upper layers of the soil and deposit in the deeper parts of the soil. Laterites are formed due to lateralization.
What are the four processes of soil formation?
Four basic processes occur in soils— additions, losses, transformations (changes), and translocation (movement). A PowerPoint presentation provides some examples. Experiments demonstrate these soil processes.
What is the difference between podzolization and Laterization?
What is Lateralisation function?
Lateralization of brain function is the view that functions are performed by distinct regions of the brain. For instance, it is believed that there are different areas of the brain that are responsible for controlling language, formulating memories, and making movements.
Which one of the following is formed by the process of leaching?
The answer is “Laterite Soil”. Laterite soil is the soil which formed due to intense leaching process.
What is meant by intense leaching?
Leaching is a mass transfer process that occurs when a substance is extracted from a solid material that has come into contact with liquid. Intense leaching: Intensive leaching occurs when leaching reaches its maximum level and begins to contaminate subsurface water. Laterite soil is formed as rain-induced leaching.
What is the difference between humification and mineralization?
Humifications the process by which simplified detritus gets converted into dark coloured amorphous substance humus in the soil. Mineralization is the process which results in the release of inorganic substances in the soil.
What is the process of mineralization?
Mineralization is the process by which chemicals present in organic matter are decomposed or oxidized into easily available forms to plants. Transformation of organic molecules in soil is mainly driven by its microbiota such as fungi and bacteria along with earthworms [38].
What soil is red?
Red soil contains a high percentage of iron content, which is responsible for its color. This soil is deficient in nitrogen, humus, phosphoric acid, magnesium, and lime but fairly rich in potash, with its pH ranging from neutral to acidic.
What soil does cotton grow best?
Black soil
Black soil is ideal for growing cotton and is also known as black cotton soil.
What are the 5 main processes of soil formation?
The whole soil, from the surface to its lowest depths, develops naturally as a result of these five factors. The five factors are: 1) parent material, 2) relief or topography, 3) organisms (including humans), 4) climate, and 5) time.
What are the 3 processes of soil formation?
Soil forming processes
Organic matter accumulation, decomposition, and humification are as critically important to soil formation as weathering. The zone of humification and weathering where pedogenic processes are dominant and where biota play an important role is termed the solum.
What are the five processes of soil formation?
These processes can be very slow, taking many tens of thousands of years. Five main interacting factors affect the formation of soil: parent material—minerals forming the basis of soil.
