Difficulty: EasyState Economy, Agriculture, and Natural Resources

Which of the following soil types, formed by the weathering of Deccan basaltic lava, is highly moisture-retentive and most suitable for dryland agriculture of cotton crops in plateau regions?

  1. Regur (Black) SoilAnswer
  2. B
    Laterite Soil
  3. C
    Desert (Arid) Soil
  4. D
    Alluvial Soil

Answer

Regur (Black) Soil is formed from basaltic lava weathering and is renowned for its high moisture retention capacity, making it exceptionally suited for rainfed cotton farming.
Regur (Black) Soil is derived from basaltic lava flows found extensively across plateau regions. Its high clay content gives it strong moisture-retention properties, making it optimal for cotton and oilseed agriculture.

Step-by-Step Solution

1
Identify parent rock material and soil characteristics mentioned in the question stem.
The stem specifies soil formed from basaltic lava with high moisture retention suited for cotton.
Parent rock (basalt) and physical property (moisture retention) determine the primary soil category.
2
Match the soil properties to the correct agricultural classification.
Regur (Black) soil is self-ploughing, rich in clay, retains moisture for long periods, and is famously known as black cotton soil.
Black soil is the characteristic soil type of the volcanic Deccan Trap region.
