Question

Chemical fertilizers contaminate our groundwater systems

Answer 1

chemical fertilizers can make the topsoil acidic, because nitrogen lowers the pH of the soil. The ideal pH for maximum plant growth and crop yield is between 5.5 and 8. If the soil is too acidic (pH lower than 5.5), it will yield less crops

Answer 2

Answer:

one of the problem with chemical fertilizers is they seep through the soil into the ground water and other water sources, leading to contamination.
