1. Proliferation of nitrogen-fixing microorganisms in soil can occur.
2. Increase in the acidity of soil can take place.
3. Leaching of nitrate to the ground-water can occur.
Select the correct answer using the code given below.

• A. 1 and 2
• B. 2 and 3
• C. 1 and 3
• D. 1, 2 and 3

Answer 1

The correct option is B 2 and 3

<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> Excessive use of fertilizers containing Nitrogen in the form of ammonia or other forms increase soil acidity, excessive nitrates would leach to groundwater and once nitrates have leached to groundwater, it is very difficult to remove it from this water. Nitrogen at higher levels also causes a loss of certain plant species, depletion of soil nutrients, death of fish and aquatic organisms, and contamination of drinking water and eutrophication.
