Question

Read the following statements with respect to soil profile and choose correct statements :
A. $OL_2$ layer is organic in ture in which plants and animals residue can be recognized visually.
B. $A_1$ layer is the uppermost mineral soil rich in organic matter.
C. $A_2$ layer is washing out zone.
D. $B_2$ layer is the zone of accumulation of clay and hydrous oxides.
E. $B_2$ layer generally lower in organic matter than that of $A_2$ layer.
Choose the correct answer from the options given below :

• A. A, B, C only
• B. B, C, D only
• C. C, D, E only
• D. A, C, D only

Hint:

Master Soil Horizons Code:
- $A_2$ E horizon = Eluviation (Washing OUT zone).
- $B_2$ B horizon = Illuviation (Accumulation IN zone).
Organic matter content decreases progressively down the profile ($A_1 > A_2 > B_2$).

Answer 1

The Correct Option is C
