Consider the following statements : 1. Agricultural soils release nitrogen oxides into environment. 2. Cattle release ammonia into environment. 3. Poultry industry releases reactive nitrogen compounds into environment. Which of the statements given above is/are correct?

A
1 and 3 only
B
2 and 3 only
C
2 only
D
1, 2 and 3
Correct Answer

Explanation

All three statements are correct because agricultural soils emit nitrous oxide through fertilizer application and microbial processes, while cattle and poultry release ammonia and other reactive nitrogen compounds through the decomposition of manure and excreta. Option (a) is a common distractor for those who associate cattle primarily with methane emissions, overlooking their significant role as a leading source of atmospheric ammonia. The core concept tested is the anthropogenic impact on the Nitrogen Cycle and the diverse agricultural sources of nitrogen pollution.
