The correct answer is Option 3.

Key Points

Black soil

• It is typical of the Deccan trap region spread over the northwest Deccan plateau and is made up of lava flows.
• It is ideal for growing cotton and is known as black cotton soil. Hence, Statement 1 is correct.
• The soil is rich in soil nutrients, such as magnesium, calcium carbonate, potash, and lime and lacks sand content. Hence, Statement 3 is not correct.
• The black soils are generally poor in phosphoric contents.
• Its structure is cloddish but occasionally friable. Hence, Statement 4 is correct.
• The black or regur soils are made up of clayey soil, well-known for their capacity to hold moisture. Hence, Statement 2 is correct.

Additional Information

• They swell and become sticky when wet and shrink when dried. So, during the dry season, this soil develops wide cracks.
• Thus, there occurs a kind of ‘self ploughing
• The colour of the soil ranges from deep black to grey.
• Black soils are derivatives of trap lava and are spread mostly across interior Gujarat, Maharashtra, Karnataka, and Madhya Pradesh on the Deccan lava plateau and the Malwa plateau.

The correct answer is 1, 2 and 3.Key Points Blac Soil

• Chemically, the black soils are rich in lime, iron, magnesia, and alumina, Hence option 1st is correct
• They also contain potash.
• But they lack phosphorous, nitrogen, and organic matter.
• The color of the soil ranges from deep black to grey.
• Black soil covers most of the Deccan Plateau which includes parts of Maharashtra, Madhya Pradesh, Gujarat, Andhra Pradesh, and some parts of Tamil Nadu.
• The black soil is intense in the upper reaches of the Godavari, the Krishna, and the Northwestern part of the Deccan Plateau.
• These soils are also known as the ‘Regur Soil’ or the ‘Black Cotton Soil’.
• The black soils are generally clayey, deep, and impermeable.
• They swell and become sticky when wet and shrink when dried.
•  So, during the dry season, these soil develop wide cracks.
• Thus, there occurs a kind of ‘self-plowing’.

 Red-Yellow Soil

• Extension: - On about 18% of the land of Madhya Pradesh
• Formation:- From the rocks of Gondwana order
• The main element:-  rich in lime

• Main crops:- Wheat, Sugarcane, Gram, Soybean, etc.
• Main area:- Some parts of Bundelkhand and mainly Baghelkhand especially Mandla, Dindori, Balaghat, Umaria, Sidhi, Singrauli, and Shahdol, Hence option 2nd is correct

 Alluvial Soil 

• Local name:- Loamy soil
• Extension:- About 3 million (in MP) acres area (8%)
• Formation:- From the deposited sediment of Chambal and other rivers
• The main element:- Predominance of sand
• Colour:- Reddish brown (due to iron oxide and aluminum)
• Main crops:- Mustard, Wheat,
• Main Area:- North-West Districts of Madhya Pradesh like Bhind, Morena, Sheorpur, Shivpuri, and Gwalior, Hence option 3rd is correct

The correct answer is option 2.

Key Points

• Statement 1: It is formed by the weathering of Deccan lava.
  • Correct.
  • Black soil (also called Regur soil) is derived from basaltic lava rocks of the Deccan Plateau, especially in western Madhya Pradesh.
• Statement 2: This soil is rich in nitrogen, phosphorus and organic matter.
  • Incorrect.
  • Black soil is rich in iron, calcium, magnesium, and potash, but it is deficient in nitrogen, phosphorus, and organic matter.
  • Hence, this statement is factually incorrect.
• Statement 3: This soil has a high capacity to retain moisture.
  • Correct.
  • One of the main features of black soil is its excellent moisture retention capacity, which supports dry farming.
• Statement 4: This soil is mainly found in the western parts of the state.
  • Correct.
  • Black soil is predominantly found in western Madhya Pradesh, especially in the Malwa Plateau and Nimar region.
