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
In the light of the above statements, choose the most appropriate answer from the options given below
Evaluating Assertion A: Farmyard Manure (FYM) Classification
Assertion A states that Farmyard Manure (FYM) is a bulky organic manure.
- FYM is produced from animal dung, urine, and bedding materials.
- It typically has a high moisture content and large volume relative to its nutrient concentration.
- These characteristics define it as a "bulky" organic manure.
Therefore, Assertion A is correct.
Evaluating Reason R: Nutrient Content of Bulky Manures
Reason R states that bulky organic manures have relatively low nutrient content per unit quantity.
- Bulky organic manures, including FYM, compost, and green manures, release nutrients slowly.
- Compared to concentrated manures, they require application in larger quantities to provide significant nutrient value.
- This lower concentration of nutrients (like Nitrogen, Phosphorus, Potassium) per kilogram or tonne is a defining feature.
Therefore, Reason R is correct.
Assessing the Relationship Between A and R
The reason why FYM is classified as a bulky organic manure (Assertion A) is directly linked to its relatively low nutrient content per unit quantity (Reason R). The bulkiness refers to its physical volume and moisture content, which are associated with lower nutrient density. Thus, the low nutrient content explains its classification as bulky.
Conclusion: Reason R provides the correct explanation for Assertion A.
Final Answer Choice
Based on the analysis:
- Assertion A is correct.
- Reason R is correct.
- Reason R is the correct explanation of Assertion A.
This corresponds to Option A.
