Which of the following agricultural fields releases the most methane gas into the atmosphere?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → Paddy field
Paddy is grown in fields kept under standing water. Bacteria that live without oxygen in the waterlogged soil break down plant matter and release methane, a greenhouse gas. Wheat, cotton and groundnut are grown on drained land, where this does not happen on any large scale.
