Features of Red and Yellow Soil
Following are the characteristics of red and yellow soil:-
Red soil is quite porous in nature and contains a high percentage of iron oxide.
Red soil is shallow and has a pH value ranging from 6.6 to 8.0.
Red soil is found to be infertile, however, it does respond to fertilizers
Both red soil and yellow soil are poor growing soils, humus and low in nutrients
These soils are difficult to cultivate since they have lower water holding capacity.
Where are Red and Yellow Soil Found?
Red yellow soil is found in the large tracts of Western Tamil Nadu, Southern Maharashtra, Karnataka, Telangana, Chhota Nagpur, Andhra Pradesh, Odisha, Chhattisgarh and plateau of Jharkhand.
Red soils are chiefly encountered on the crystalline igneous rocks in regions of low rainfall in the southern and eastern parts of the Deccan Plateau.
These soils tend to establish a reddish hue simply because of the diffusion of iron in rocks (crystalline and metamorphic). The soil starts to look yellow when it occurs in a hydrated form.
Introduction Red to Yellow Soils
Apart from the features of red and yellow soil, there is some factual information about these soils which is as below;-
Red and yellow soils are basically found over extensive non alluvial tracts of peninsular India.
These soils are composed of acidic rocks such as gneiss, granite, and schist.
Red and yellow soils develop in areas in which rainfall drains soluble minerals out of the ground and outcomes in a loss of chemically based constituents; further leading to a corresponding proportional increase in oxidized iron executing a reddish hue to many such soils.
As a result of oxidation, these soils are commonly described as ferralitic soils.
In acute cases, the concentration of oxides of iron results in the formation of a hard crust, in which case they are defined as lateritic (for later, the Latin term implying “brick”) soils.
The highly leached red to yellow soils are distilled in the massive-rainfall areas of the western Kathiawar Peninsula, the Western Ghats, the Eastern Ghats, eastern Rajasthan region, the Chota Nagpur plateau, and other upland tracts of northeastern India.
Less-leached red to yellow soils develop in areas of low rainfall in the immediate east of the Western Ghats in the dry interior of the Deccan.
Red-to-yellow soils are generally not fertile, but that issue is partly improved in forested tracts, where recycling of nutrients and the concentration of humus enables restoring fertility in the topsoil.
Introduction to Black Soils
In the midst of in situ soils of India, the black soils found in the lava-covered areas are the most noticeable. Those soils are most commonly referred to as regur but are widely known as “black cotton soils,” seeing that cotton has been an accustomed traditional crop in areas where they are found.
Where is Black Soil Found?
Black soils are derivatives of trap lava and are spread widely across the interior Gujarat, Karnataka, Maharashtra, and on the Deccan lava plateau and the Malwa Plateau of Madhya Pradesh, where there is both underlying basaltic rock and moderate rainfall.
How is Black Soil Developed?
Due to the presence of their high clay content, black soils develop huge cracks during the dry season, but their iron-rich granular composition makes them resistant to wind and water erosion. They are poor in humus but still highly moisture-retentive, therefore well responsive to irrigation. Black soils are also found on various peripheral tracts where the underlying basalt has been moved from its original position by fluvial processes. The moving though results in an increased concentration of clastic (chalky sedimentary) contents.
Introduction to Alluvial Soils
Allvial soil is widespread but they are most found throughout the Indo-Gangetic Plain and along the lower courses of nearly all the country’s major rivers (particularly the deltas along the east coast). The nondeltaic plains along India’s coasts are also characterized by the slender ribbons of alluvium.
Where is Alluvial Soil Found?
New alluvium known as the khadar is found on much of the Indo-Gangetic floodplain. It is highly fertile and uniform in texture; in opposition to, the old alluvium on the minutely elevated terraces, called the bhangar, carries patches of alkaline efflorescences, known as the usar, manifesting some areas infertile. In the Ganges basin, sandy aquifers bearing an expansive reserve of groundwater make sure for irrigation and also enable making the plain the most agriculturally productive area of the country.
Fun Facts on Red Yellow Soil
Red soils are formed on crystalline igneous rocks in regions of low rainfall in the eastern and southern areas of the Deccan Plateau.
Soils appear yellow when they develop in a hydrated form.
FAQs on Red to Yellow Soil
Q1. What Does Plinthosol Mean in Soil Groups?
Answer: Plinthosol is amongst the thirty soil groups under the subdivision of the Food and Agriculture Organization. Plinthosols is typically developed under a number of climatic and topographic conditions. They are described by a subsurface layer consisting of an iron-rich mixture of clay minerals (primarily kaolinite) and silica that toughens on exposure into ironstone concretions referred to as plinthite. The impenetrability of the toughened plinthite layer, and also the oscillating water table that generates it, limit the use of these soils to grazing or forestry, although the toughened plinthite contains value as a subgrade substance for roads or even as iron ore. It is quite amazing to know that Plinthosols occupy about 0.5 % of the total continental land area on Earth, chiefly in Brazil and West Africa. An associated soil group also originates in the tropics termed as Nitisol.
Q2. What is Alisol?
Answer: Alisol is amongst the 30 soil groups under the division system of the Food and Agriculture Organization (FAO). Alisols are extremely acidic, poorly leached soils that are disposed of to aluminium toxicity and water erosion. Liming and fertilization play a crucial role in their agricultural use—mainly for growing corn (maize), oil palm, and cotton. Their extent has not been entrenched definitively, but they are thought to have occupied less than 1% of the total land area on Earth, principally in the southeastern United States (in soil zones presently categorized as Acrisols) and Malaysia.
