Black Soils Coverage and Characteristics
This section analyzes the correctness of the statements about Black Soils in India.
Statement Analysis
- Statement 1: Black Soils cover most of the Deccan Plateau. This statement is correct. Black soils, known for their origin from volcanic activity, predominantly cover the vast expanse of the Deccan Plateau in India.
- Statement 2: Also known as 'Regur', they are generally clayey, deep and impermeable. This statement is correct. 'Regur' is a common name for Black soil. Its characteristics include a high clay content, significant depth, and poor drainage, making it impermeable.
- Statement 3: Since they are impermeable, rainfed crops do not grow well in Black Soils. This statement is incorrect. Despite being impermeable, Black soils have excellent moisture-retention capacity. This quality makes them highly suitable for rainfed agriculture, particularly for crops like cotton. The impermeability mainly poses a risk of waterlogging with excessive irrigation rather than hindering rainfed crops.
Conclusion on Statements
Based on the analysis, statements 1 and 2 are correct, while statement 3 is incorrect.
Selected Answer Justification
Therefore, the correct option includes only statements 1 and 2.
