How do chemical fertilizers cause water pollution?
How Chemical Fertilizers Cause Water Pollution? Chemical fertilizers contain phosphates, nitrates that can actually be the main reason behind water pollution. Environmental nitrogen and phosphorous contribute to the process of Eutrophication, which enriches the water surface with nutrients.
What happens to fertilizers when it rains?
Even if fertilizers are not used near a body of water, rainfall eventually washes them into streams and rivers. Fertilizers contain three primary plant nutrients: mostly nitrogen and phosphorous with smaller amounts of potassium.
Are inorganic fertilizers bad for the environment?
Though, inorganic fertilizers are not directly toxic to man and other life forms, they have been found to upset the existing ecological balance. The nutrients escape from the fields and are found in excessive quantities in under ground water, rivers, lakes and coastal waters.
Does nitrogen fertilizer contribute to groundwater contamination?
Nitrogen fertilizers containing nitrates can contaminate groundwater because nitrates are highly soluble in water. At high levels, nitrates can poison humans, particularly children.
