EUTROPHICATION Eutrophication is a syndrome of the ecosystem, response to the addition of
artificial or natural nutrients such as nitrates and phosphates through fertilizer, sewage, etc.
that fertilize the aquatic ecosystem. It is primarily caused by the leaching of phosphate and - or
nitrate-containing fertilizers from agricultural lands into lakes or rivers.
The growth of
green algae on the lake surface layer is the physical identification of a Eutrophication.
