Consider the following statements:
- 1.Agricultural soils release nitrogen oxides into the environment.
- 2.Cattle release ammonia into the environment.
- 3.The poultry industry releases reactive nitrogen compounds into the environment.
- A.1 and 3 only
- B.2 and 3 only
- C.2 only
- D.1, 2 and 3
▶ Answer & Explanation
Correct answer: D. 1, 2 and 3
Agricultural soils are significant sources of nitrogen oxides (N2O), primarily through denitrification processes. Livestock, particularly cattle, excrete large amounts of nitrogen in their waste, leading to ammonia (NH3) volatilization. The poultry industry also contributes to reactive nitrogen compound emissions through manure management, which can release ammonia and other nitrogenous gases.
