What happens when an excess aont of nitrogen fetilizer is introduced inot the soil ecosystem
Answers
Answer:
Nitrogen is an essential element for plant growth and development; however, due to environmental pollution, high nitrate concentrations accumulate in the edible parts of these leafy vegetables, particularly if excessive nitrogen fertilizer has been applied.
Explanation:
Once nitrogen fertilizers are applied to agricultural systems, the fertilizers are absorbed directly by plants or converted into various other forms through the oxidation process. Excess nitrogen is lost in ionic or gaseous form through leaching, volatilization, and denitrification. If nitrate is not absorbed by plant roots, it is carried away by runoff or leaches into the soil along with water. The phytoavailability of the nitrogen pool increases when excess nitrogen is applied, and this increase intensifies the potential threat to the surrounding environment. There are close relationships between the excessive application of nitrogen fertilizers and environmental problems such as eutrophication, the greenhouse effect, and acid rain. Consuming contaminated groundwater or crops with a high concentration of nitrate has negative effects on human health.
