Which of the following statements about the Black Soils of India is/are correct ? 1. Black Soils cover most of the Deccan Plateau. 2. Also known as 'Regur', they are generally clayey, deep and impermeable. 3. Since they are impermeable, rainfed crops do not grow well in Black Soils. Select the answer using the codes given below :

Statement 1 is correct: Black soils, also known as Regur soils, are characteristic of the Deccan Trap (Basalt) region. They cover most of the Deccan Plateau, including Maharashtra, Saurashtra, Malwa, and parts of Madhya Pradesh and Chhattisgarh.

Statement 2 is correct: These soils are typically clayey, deep, and impermeable. A unique feature is their high water-retaining capacity; they swell and become sticky when wet and develop deep cracks when dry, which aids in self-aeration (self-ploughing).

Statement 3 is incorrect: Because of their high moisture-retention capacity, black soils are exceptionally suitable for rainfed crops. They retain moisture for long periods, which helps crops like cotton, pulses, and oilseeds survive even during dry spells. Therefore, rainfed agriculture actually thrives in these soils rather than performing poorly.
