Questions Related to classification of soils

Black cotton soil of the Deccan region is associated with ________ rocks.

  1. Volcanic rocks

  2. Plutonic rocks

  3. Sedimentary rocks

  4. Hypabysal rocks


Correct Option: A
Explanation:

Black soil is typical of the Deccan trap (Basalt) region spread over northwest Deccan plateau and is made up of Volcanic lava flows. 

The soil that has very poor fertility status _______________.

  1. Alluvial soils

  2. Black cotton or regular soils

  3. Laterite soils

  4. Red soils


Correct Option: C
Explanation:

Laterite has been derived from the Latin word ‘later’ which means brick. The laterite soil develops in areas with high temperature and heavy rainfall. This is the result of intense leaching due to heavy rain. Humus content of the soil is low because most of the micro organisms, particularly the decomposers, like bacteria, get destroyed due to high temperature. Laterite soils are suitable for cultivation with adequate doses of manures and fertilizers. These soils are mainly found in Karnataka, Kerala, Tamil Nadu, Madhya Pradesh, and the hilly areas of Odisha and Assam. 

Soil formed by intensive leaching is _____.

  1. Alluvial soil

  2. Red soil

  3. Laterite soil

  4. Desert soil


Correct Option: C
Explanation:

The Laterite Soil is the type of soil formed from intense leaching in areas of high rainfall , moisture and high temperature. The soil formed by the process of intense leaching is laterite soil.

The most fertile soil is ______.

  1. Red soil

  2. Alluvial soil

  3. Laterite soil

  4. Mountainous soil


Correct Option: B
Explanation:

Alluvial soils as a whole are very fertile. Mostly these soils contain adequate proportion of potash, phosphoric acid and lime which are ideal for the growth of sugarcane, paddy, wheat and other cereal and pulse crops. Due to its high fertility, regions of alluvial soils are intensively cultivated and densely populated.

Black soil is rich in _____.

  1. Calcium carbonate

  2. Magnesium

  3. Potassium and lime 

  4. All of these


Correct Option: D
Explanation:
