Detailed explanation-1: -When manure or commercial fertilizers enter surface water, the nutrients they release stimulate microorganism growth. The growth and reproduction of microorganisms reduce the dissolved oxygen content of the water body. Without sufficient dissolved oxygen in surface water, fish and other aquatic species suffocate.
Detailed explanation-2: -Green up the garden, not the waterways – over-fertilization causes nutrient pollution. Algae blooms, caused by nutrient pollution, kill fish and can turn water toxic. With spring comes the greening of lawns and gardens-and, by extension, the greening of rivers, streams and other bodies of water.
Detailed explanation-3: -Fertilization of surface waters (eutrophication) results in, for example, explosive growth of algae which causes disruptive changes to the biological equilibrium [including fish kills]. This is true both for inland waters (ditches, river, lakes) and coastal waters. Groundwater is being polluted mainly by nitrates.
Detailed explanation-4: -Fertilizers contain high levels of nitrogen and phosphorus, which can lead to oxygen depletion, overgrowth of vegetation, and fish kills. In order to protect wildlife and aquatic species from pesticides, herbicides, and fertilizers that pollute our waters, buffer zones need to be enforced.
