Natural eutrophication: The natural addition of excessive nutritional substances in a lake or body of water. Eutrophication may be defined as the inorganic nutrient enrichment of natural waters, leading to an increased production of algae and macrophytes. Natural eutrophication is a very slow process, and is somewhat temperature dependent. Over time, the lake may accumulate so much sediment that it fills in and becomes a swamp or a meadow. Eutrophication occurs naturally over centuries as lakes age and are filled in with sediments (Carpenter 1981). Become a Study.com member to unlock this This view is based on a mis-understanding. Cultural Eutrophication. This natural eutrophication process occurs over extended periods of time that are typically geological time scales. reducing the use of lawn fertilizers. Cultural eutrophication causes major changes in the water with the addition of excess amount of nutrients; mainly phosphate and nitrates. Eutrophication is a process whereby there is an overabundance of nutrients in a water body. As the nutrient availability increases, more plant growth is supported in the lake; this can include both benthic, or bottom-rooted, plants, and also those that float.

They are important processes triggered by both natural and unnatural substances or occurrences that can’t be stopped by men when it has occurred. Many lakes are naturally eutrophic and in some cases there is a progressive eutrophication as the lake matures. Natural eutrophication is a very slow process, and is somewhat temperature dependent. Cultural or artificial eutrophication occurs when human activity introduces increased amounts of these nutrients, which speed up plant growth and eventually choke the lake of all of its animal life. It is also common when sewage, either treated or untreated, enters a body of water, and when the outflow from septic tanks enters a stream or pond. Since the industrial revolution however, eutrophication of many water bodies has escalated as a result of anthropogenic nutrient input. Already a member?
