Question

The soil with self ploughing capacity:

• A. Alluvial Soil
• B. Red Soil
• C. Black Soil
• D. Laterite Soil

Answer 1

Answer:

C. Black Soil

Black Soil is often referred to as having self-ploughing capacity.

Black Soil, also known as Regur Soil, is rich in clay and is particularly found in regions like Maharashtra, Madhya Pradesh, Gujarat, Karnataka, and parts of Tamil Nadu. It is known for its moisture-retaining capacity and high fertility, making it ideal for crops like cotton, groundnut, and soybean.

The term self-ploughing capacity refers to the soil's ability to crack open naturally during dry periods, which helps in loosening the soil without the need for additional mechanical ploughing. This cracking is due to the high content of montmorillonite clay, which expands when wet and contracts upon drying, creating a natural process that improves soil aeration and structure.

This characteristic makes black soil especially beneficial for dryland farming and helps in reducing the need for frequent manual or mechanical ploughing.
