Zorluk: OrtaSoils, Natural Vegetation, and Agriculture in India

Arrange the following major soil groups of India in decreasing order of their percentage contribution to the total geographical area of the country:

  1. 1Alluvial Soil
  2. 2Red Soil
  3. 3Black Soil
  4. 4Laterite Soil

Cevap

The correct decreasing order of major soil groups by geographical area coverage in India is: Alluvial Soil, followed by Red Soil, Black Soil, and Laterite Soil.
According to the Indian Council of Agricultural Research (ICAR), the correct decreasing order of major soils by share of total geographical area is Alluvial Soil (~43%43\%), Red Soil (~18.5%18.5\%), Black Soil (~15%15\%), and Laterite Soil (~4.3%4.3\%).

Adım Adım Çözüm

1
Assess the coverage of Alluvial Soil in India.
Alluvial soil covers approximately 43%43\% of India's land surface.
Deposition by major river networks (Indo-Gangetic-Brahmaputra system and eastern coastal rivers) makes it the most widespread soil.
2
Compare the spatial coverage of Red Soil and Black Soil.
Red soil covers about 18.5%18.5\% of the geographical area, while Black soil (Regur) covers about 15%15\%.
Weathering of crystalline metamorphic rocks creates extensive red soil tracts across Tamil Nadu, Karnataka, Andhra Pradesh, and Odisha, surpassing the extent of black volcanic soils.
3
Identify the geographical extent of Laterite Soil.
Laterite soil accounts for approximately 4.3%4.3\% of the total area.
Intense leaching under high rainfall conditions restricts laterite soils to specific highland regions.
4
Arrange the soils in decreasing order of area.
Alluvial Soil (43%43\%) > Red Soil (18.5%18.5\%) > Black Soil (15%15\%) > Laterite Soil (4.3%4.3\%).
This matches the official Indian Council of Agricultural Research (ICAR) land area classification.
