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

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

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

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

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

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