How does the excessive use of fertilizers contaminate the underground water?
Answers
These can enter the water bodies through surface runoff or during rain or contaminate ground water by leaching . Excess nitrogen or phosphorus in surface water is a cause excess growth of algae, dissolved oxygen deficits.This pollutes the land.
Chemical fertilizers are one of the most important cities of the modern agricultural production process and these chemical fertilizers are both blessing and curse for the agricultural production.
The excessive usage of these chemical fertilizers can contaminate the underground water bodies because the soil layer between the underground water body and the upper surface of the harvesting land is partial permeable and the excessive amount of chemical fertilizers can easily reach the underground water bodies through this soil layer.
