Which of the following soil requires minimum tillage because of its self-cultivating feature?

The correct answer is Black soil.
Key Points

• Black soil is also known as regur soil or black cotton soil.
• It is found in the Deccan plateau and is particularly well-suited for growing cotton crops.
• It has a high clay content, which makes it highly retentive of moisture and nutrients.
• This means that it requires less frequent irrigation and fertilization, which in turn reduces the need for tilling and weeding.
• The high clay content also makes black soil heavy and difficult to plow, which is why it is often referred to as "sticky" soil.
• However, this also means that it is highly stable and resistant to erosion.

Additional Information

• Peaty soil (option 3) is a type of soil that is characterized by a high organic content.
  • It is found in wetlands and marshes and is not suitable for agriculture.
• Laterite soil (option 2) is a type of soil that is formed in tropical and subtropical regions.
  • It is highly weathered and has a high iron and aluminum content.
  • It is not suitable for agriculture.
• Red soil (option 1) is a type of soil that is commonly found in India.
  • It is formed from the weathering of igneous rocks and has a reddish color due to the presence of iron oxide.
  • It is suitable for growing crops like pulses, millets, and oilseeds.
• Hence, the statement "The correct answer is option 4" is correct.
