Consider the following statements:

  1. Agricultural soils release nitrogen oxides into the environment.
  2. Cattle release ammonia into the environment.
  3. Poultry industry releases reactive nitrogen compounds into environment.

Which of the statements given above is/are correct?

Explanation

All three statements (1, 2, and 3) are correct.

Statement 1 is correct: Agricultural soils are a major source of nitrogen oxides (NOx) emissions, primarily nitrous oxide (NO). This occurs during microbial processes in the soil, such as nitrification and denitrification.

Statement 2 is correct: Cattle release significant amounts of ammonia (NH) into the atmosphere through their urine and manure. This ammonia contributes to air pollution and can have negative environmental consequences.

Statement 3 is correct: The poultry industry releases various reactive nitrogen compounds into the environment, including ammonia, nitrous oxide, and nitrogen oxides. These emissions come from poultry manure and the use of nitrogen-based fertilizers in feed production.
