Cultural eutrophication is a form of water pollution. It also occurs when excessive fertilizers run into lakes and rivers.
Cultural or anthropogenic eutrophication is water pollution caused by excessive plant nutrients. Links. Eutrophication-Eutrophication (pronounced you-tro-fi-KAY-shun) is a natural process that occurs in an aging lake or pond as that body of water gradually builds up its concentration of plant nutrients. Eutrophication-Definition, Glossary, Details-Oilgae. Eutrophication-Natural eutrophication is the process by which lakes gradually age and become more productive. It normally takes thousands of years to progress. Eutrophication arises from the oversupply of nutrients, which induces explosive growth of plants and algae which, when such organisms die, consume the oxygen in the body of water, thereby creating the state of hypoxia. According to Ullmann's Encyclopedia, the primary limiting factor for eutrophication is phosphate.. Cultural eutrophication is the process that speeds up natural eutrophication because of human activity. Due to clearing of land and building of towns and cities, land runoff is accelerated and more nutrients such as phosphates and nitrate are supplied to lakes and rivers, and then to coastal estuaries and bays.

Eutrophication (pronounced you-tro-fi-KAY-shun) is a natural process that occurs in an aging lake or pond as that body of water gradually builds up its concentration of plant nutrients. In nature, eutrophication is a common phenomenon in freshwater ecosystems and is really a part of the normal aging process of many lakes and ponds. Some never experience it because of a lack of warmth and light, but many do. Effects of eutrophication are:- 1.} Excessive growth of algae in the water bodies such as rivers etc. 2.} Depletion of oxygen in the water which results in the death of fishes … etc. and thus a clean water body turns into a stinking drain. Confidence votes 45. Cultural eutrophication is an increase in biological productivity and ecosystem succession caused by human activity. It is mainly caused by increased nutrient input into a water body. Increased productivity in an aquatic system sometimes can be beneficial. Cultural eutrophication is a form of water pollution. Cultural eutrophication also occurs when excessive fertilizers run into lakes and rivers. This encourages the growth of algae (algal bloom) and other aquatic plants. Following this, overcrowding occurs and plants compete for sunlight, space and oxygen. Cultural eutrophication is the process that speeds up natural eutrophication because of human activity. Due to clearing of land and building of towns and cities, land runoff is accelerated and more nutrients such as phosphates and nitrate are supplied to lakes and rivers, and then to coastal estuaries and bays. Eutrophication Eutrophication is a process in which bodies of water (lakes, ponds, and rivers) receive excess nutrients that stimulate excessive growth of algae. The two most … common nutrients that initiate eutrophication are nitrogen and phosphorous, two limiting nutrients in the growth of algae. Confidence votes 45. Cultural eutrophication is an increase in biological productivity and ecosystem succession caused by human activity. It is mainly caused by increased nutrient input into a water body. Increased productivity in an aquatic system sometimes can be beneficial. Definition of EUTROPHICATION. : the process by which a body of water becomes enriched in dissolved nutrients (as phosphates) that stimulate the growth of aquatic plant life usually resulting in the depletion of dissolved oxygen. ADVERTISEMENT. Britannica.com: Encyclopedia article about eutrophication Eutrophication is a natural process that typically occurs as lakes age. However, human-caused, accelerated eutrophication (called cultural eutrophication) occurs more rapidly, and causes problems in the affected water bodies, as described below. 1. EUTROPHICATION. Fertilizers cause problems with water quality when they runoff into rivers or percolate into groundwater. In fact, agriculture (including livestock agriculture) is the largest source of nonpoint water pollution in the US. Eutrophication-Eutrophication is a process whereby water bodies, such as lakes, estuaries, or slow-moving streams receive excess nutrients that stimulate excessive plant growth (algae, periphyton attached algae, and nuisance plants weeds).
