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 enrichment.
\nCompost enhances soil by increasing organic matter, improving texture, boosting water retention, and optimizing fertilizer use. \n\[\n(A) \; \text{Correct}\n\] \n\n \n

Step 2: Impact of warm climates.
\nA warm tropical climate stimulates microbial activity, thereby making composting more efficient. Consequently, the claim that it is least suitable is inaccurate. \n\[\n(B) \; \text{Incorrect}\n\] \n\n \n

Step 3: The composting process.
\nComposting is fundamentally an aerobic, thermophilic process, involving the decomposition of organic matter by microorganisms at high temperatures (45–70°C). \n\[\n(C) \; \text{Correct}\n\] \n\n \n

Step 4: Composting methodologies.
\nTwo primary methods are: \n- Windrow composting: Organic materials are arranged in long piles and periodically turned. \n- In-vessel composting: Decomposition occurs within enclosed systems under controlled conditions. \n\[\n(D) \; \text{Correct}\n\] \n\n \n

Step 5: Summary of correct statements.
\nThe accurate statements are (A), (C), and (D). \n\n \n

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