Answer 2

Answer:

Option C – Increase in soil acidity and leaching to ground water.

Explanation:

Nitrogen is one of the nutrients, which affect the pH level of soil. Therefore, excess of nitrogen in the soil through improper use of fertilisers, can affect the acidity of the soil.

Plants do not absorb all the nitrogen in soil. The excess nitrogen will leach from the soil and contaminate the ground water resources, which when consumed regularly can cause health problems.
