Geography · भारत की मिट्टी · Questions 41–50 of 50
Which soil is famously known as 'Self-mulching soil'?
Correct Answer: D. Black Soil
Black soil is called self-mulching because it shrinks and cracks when dry. The surface soil falls into the cracks, ensuring a natural turning of the soil layers. This helps in maintaining moisture in the lower levels.
In which part of India would you most likely find Peaty and Marshy soils?
Correct Answer: D. Coastal Odisha and Tamil Nadu
Peaty and marshy soils occur in the humid coastal regions of Odisha, West Bengal, and Tamil Nadu. They are formed from the accumulation of large amounts of organic matter. These soils are often acidic and heavy.
The removal of soil by the action of wind and water is collectively known as?
Correct Answer: B. Soil Erosion
Soil erosion is the displacement of the upper layer of soil. It is caused by natural agents like wind and water, often accelerated by human activities like deforestation. It leads to the loss of agricultural productivity.
Which type of soil is found in the 'Bhabar' region of India?
Correct Answer: B. Pebbly and porous soil
Bhabar is a narrow belt at the foot of the Himalayas where rivers deposit pebbles. The soil is very porous, and smaller streams often disappear underground in this region. It is not very suitable for regular cultivation.
Which state has the largest area of Black Soil in India?
Correct Answer: D. Maharashtra
Maharashtra has the largest concentration of black soil in India. It is followed by Gujarat and Madhya Pradesh. This soil is vital for the state's dominant cotton-based economy.
What is the primary crop grown in the Red Soils of the Deccan plateau?
Correct Answer: B. Pulses and Millets
Red soils are less fertile but, with fertilizers and irrigation, can grow millets, pulses, and oilseeds. These crops are well-adapted to the relatively dry conditions of the eastern Deccan. Tobacco and groundnut are also grown in these soils.
Which soil is mostly used for manufacturing bricks for building construction?
Correct Answer: B. Laterite Soil
Laterite soil is widely used for making building bricks because it hardens significantly upon drying. It is cut into blocks and used as a durable construction material. This practice is common in southern India.
The 'Bundelkhand' region is mostly characterized by which soil?
Correct Answer: D. Mixed Red and Black Soil
The Bundelkhand region (UP/MP border) features a mixture of red and black soils. This transition zone shows characteristics of both the peninsular plateau and the plains. It presents unique challenges for agriculture due to low water retention in some parts.
Contour Bunding is a method of soil conservation used in?
Correct Answer: A. Hilly regions
The correct answer is 'Hilly regions'. Contour bunding involves building small barriers or embankments along the natural contours of a slope. This helps in catching rainwater and prevents it from washing away the topsoil. It is a vital technique for mountain agriculture.
Which soil is generally rich in Potash but poor in Phosphorus?
Correct Answer: A. Alluvial Soil
Alluvial soil is typically rich in potash and lime but poor in phosphorus and nitrogen. This chemical balance makes it excellent for most crops with minor fertilization. It is the most productive soil in India.
