Question

Choose the correct statement(s) with regard to composting.

• A. It produces natural soil amendment and enhances the effectiveness of fertilizer.
• B. Warm temperature of tropical regions is least suitable for composting.
• C. Composting is an aerobic thermophilic process.
• D. Windrow composting and in-vessel composting are two of the common composting methods.

Hint:

Tropical warm climate = ideal for composting. Remember: Aerobic + thermophilic microbes = faster decomposition.

Answer 1

The Correct Option is A, C, D

Step 1: Composting and soil amendment.
Compost enriches soil organic matter, improves soil texture, increases water holding capacity, and enhances the efficiency of chemical fertilizers. \[ (A) \; \text{Correct} \]

Step 2: Effect of warm climate.
Warm tropical climate actually accelerates microbial activity, making composting more effective. Hence, the statement that it is least suitable is false. \[ (B) \; \text{Incorrect} \]

Step 3: Composting process.
Composting is essentially an aerobic, thermophilic process, where microorganisms decompose organic matter at elevated temperatures (45–70°C). \[ (C) \; \text{Correct} \]

Step 4: Methods of composting.
Two common methods: - Windrow composting: Organic waste placed in long rows and turned regularly. - In-vessel composting: Waste decomposed inside enclosed units under controlled conditions. \[ (D) \; \text{Correct} \]

Step 5: Conclusion.
Correct statements = (A), (C), (D).

Final Answer: \[ \boxed{\text{(A), (C), and (D)}} \]
