Single correct option

Consider the following statements about black soil (regur):
1. It is formed by the weathering of basaltic lava of the Deccan Trap.
2. It is rich in nitrogen and organic matter.
Which of the statements given above is/are correct?
  1. A. 1 only
  2. B. 2 only
  3. C. Both 1 and 2
  4. D. Neither 1 nor 2
Show answer and solution

Answer: (A) 1 only

Black soil forms from the weathering of Deccan basalt, is rich in lime, iron, calcium and magnesium and retains moisture, so it suits cotton. However, it is poor in nitrogen, phosphorus and organic matter, so statement 2 is wrong. Statement 1 alone is correct.
