Question

What type of soil is called ‘Soudu’?
A) Sandy soil
B) Loamy soil
C) Saline soil
D) Black soil

Answer 1

Hint: Soil is made up of organic matter, minerals, gases, liquids, and organisms, all of which work together to support life. The pedosphere, or body of soil on Earth, has four vital functions: it serves as a medium for plant growth. as a means of storing, supplying, and purifying water.

Complete answer:
Let us analyze the given options:
Option A) Sandy soil: This is not the correct option because Sandy soils are commonly referred to as "light soils" due to their high sand content and lack of clay (clay weighs more than sand). These soils are easy to work with and have good water drainage.

Option B) Loamy soil: This is not the correct option because Loam is a form of soil that combines the three primary types of soil: sand, silt, and clay. Loam soil should, in general, include equal amounts of all three soil types. The soil texture created by this combination of soil types is ideal for plant growth.

Option C) Saline soil: This is the correct option because Soudu is the name for saline soil. Excessive quantities of soluble salts in the soil water (soil solution) are known as saline soil, and they can significantly effect plant growth, resulting in lower crop yields and even plant mortality in extreme cases.

The establishment of salt-tolerant plants has been demonstrated to improve the physical qualities of saline soils. Water uptake in soil, saturated hydraulic conductivity of soil, structural stability, bulk density of soil, and soil porosity have all been demonstrated to improve with these plant species. The amount of available water is related to the amount of organic matter in the soil and the porosity of the soil.

Option D) Black soil: This is not the correct option because Black soils are trap lava derivatives found predominantly on the Deccan lava plateau and the Malwa Plateau in interior Gujarat, Maharashtra, Karnataka, and Madhya Pradesh, where there is moderate rainfall with underlying basaltic rock.

Thus the correct answer is option ‘C’.

Note: Although the reasons for saline and sodic soils in the northern Great Plains are natural, management can have an impact on both conditions. The parent material of the state's soils, as well as the underlying sodium-rich shale present in the bedrock beneath the soil deposits, are the primary natural causes for these two.
