Detailed Solution

The given statement is false.
Farmers replenish the soil with nitrogen by adding fertilisers that increase the soil's nitrogen content and improve its fertility. While nitrogen is present in the environment at constant levels, excessive use of nitrogen fertilisers can have negative impacts on the environment. Nitrogen can leach into waterways, leading to eutrophication, or excess growth of algae and other aquatic plants that deplete oxygen levels and harm aquatic organisms. Additionally, nitrogen fertilisers can contribute to air pollution when they are converted into gases such as ammonia and nitrogen oxide. Therefore, it is essential to use fertilisers responsibly and adopt sustainable farming practices to minimise the environmental impact.
The correct statement is "The use of fertilizer does not affect the nitrogen cycle by adding nitrogen to the atmosphere.".
