1.	Given figure represents the soil profile, showing different layers/horizons of soil. Which of the following statements regarding the soil profile are not true ? (i) Maximum roots of plants are found in horizon `A`. (ii) Maximum nutrients are present in horizon `B`. (iii) Horizon `B` contains partly weathered rocks. (iv) Horizon `C` contains roots of the plants and mineral salts.A. (i) and (ii)B. (i) and (iii)C. (ii) and (iv)D. (i),(ii) and (iii)
Answer» Correct Answer - C Maximum nutrients are found in the uppermost O-horizon. It contains organic matter in various stages of decomposition which produces human. It is a reservoir of plant nutrients. Roots of most of the plants remains restricted to A-Horizon. This is also called top-soil and is rich in microorganisms.
