Question

Given below are two statements, one is labelled as Assertion A and the other is labelled as Reason R
Assertion A: Infiltration rate is found to vary inversely with soil moisture content.
Reason R: With the increase in soil moisture content, the soil pores are filled with water.
In light of the above statements, choose the correct answer from the options given below

• A. Both A and R are true and R is the correct explanation of A
• B. Both A and R are true but R is NOT the correct explanation of A
• C. A is true but R is false
• D. A is false but R is true

Hint:

Dry soil has a high matric suction gradient, resulting in a high initial infiltration rate. As pores fill with water, this suction gradient drops to zero, and infiltration slows to a constant rate driven only by gravity.

Answer 1

The Correct Option is A
