This questions was previously asked in
UPSC CSP Previous Year Paper (2019)
1 and 3 only
Incorrect Answer2 and 3 only
Incorrect Answer1, 2 and 3
Correct AnswerExplanation:
Nitrous oxide emission arising from nitrogen leaching and run-off from agricultural soils. After fertilizer application or heavy rain, large amounts of nitrogen may leach from the soil into drainage ditches, streams, rivers and eventually estuaries.
Ammonia is a common by-product of animal waste due to the often inefficient conversion of feed nitrogen into animal product. Emissions of ammonia from livestock farming are responsible for the acidification and eutrophication of deposited ammonia in the environment.
Reactive nitrogen includes – ammonia, nitrate, nitric oxide (NO), nitrous oxide (N2O). Livestock and Poultry are both responsible.
Therefore, all the statements are correct.
