Question

excess use of fertilizers is not advisable how may it cause water pollution​

Answer 1

When manure or commercial fertilizers enter surface water, the nutrients they release stimulate microorganism growth. ... Without sufficient dissolved oxygen in surface water, fish and other aquatic species suffocate. The resulting dead fish and other aquatic species degrade the water quality and cause unpleasant odors.

Answer 2

Answer:

Excess of fertilizers are washed away into the surrounding water bodies. Thus, concentration of nitrates and phosphorus in the ground and surface water increases making it unfit for use.
