Question

Given below are two statements: Assertion (A): Farmyard manure (FYM) is a bulky organic manure. Reason (R): Bulky organic manures are relatively low in nutrient content per unit quantity of the material.

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

Hint:

FYM is a bulky organic manure because it has low nutrient content and is applied in large quantity.

Answer 1

The Correct Option is A

Concept:
Organic manures are broadly classified into bulky organic manures and concentrated organic manures.

Step 1: Check Assertion.
Farmyard manure contains decomposed mixture of dung, urine, litter, and leftover organic materials. It is applied in large quantity because its nutrient content per unit weight is low. \[ A \text{ is correct} \]

Step 2: Check Reason.
Bulky organic manures are low in nutrient content per unit quantity and are applied in large amounts. \[ R \text{ is correct} \]

Step 3: Check explanation.
FYM is called bulky organic manure because it contains relatively low nutrient concentration and must be used in bulk quantity. \[ R \text{ correctly explains } A \] \[ \therefore \text{Correct Answer is (A)} \]
