from The American Heritage® Dictionary of the English Language, 4th Edition
- adj. Having waters rich in mineral and organic nutrients that promote a proliferation of plant life, especially algae, which reduces the dissolved oxygen content and often causes the extinction of other organisms. Used of a lake or pond.

- adj. being rich in nutrients and minerals and therefore having an excessive growth of algae and thus a diminished oxygen content to the detriment of other organisms

- adj. (ecology) of a lake or other body of water rich in nutrients and subject to eutrophication
Within the miombo vegetation, "islands" of other vegetation types, such as eutrophic savanna on richer soils, river terraces and floodplains, provide superior forage.
As Selman explained, the doubling of nitrogen and tripling of phosphorous in the environment since 1960 -- primarily from intensive agriculture - correlates with the explosive growth in the number of hypoxic and eutrophic sites.
So while we might classify a site as becoming eutrophic/hypoxic in the 2000's, maybe it was experiencing issues beforehand.
One of the map's most powerful features is its ability to show the locations of hypoxic and eutrophic sites over time.
Enter the World Resources Institute (WRI) and its interactive and exhaustively-researched map of 762 (and counting) eutrophic and hypoxic sites around the world, each identified with accompanying descriptions, photos and even videos.
Some soils are eutrophic, or nutrient-rich, in many areas.
The bottomland soils are rich from alluvial deposits and the uplands are eutrophic podzols.
Topographic variability begets biological heterogeneity in the Tapajós-Xingu region, and where there are eutrophic soils they sustain a rich and diverse biota with a high occurrence of endemism.
But after drought between 1982 and 1994, the water fell to an average depth of one meter and became hyper-eutrophic with nitrogen and phosphorus from farm wastes, fertilizers, pesticides and sediment.
Lake densities are generally lower here than in the Northern Lakes and Forests, and lake trophic states tend to be higher, with higher percentages in eutrophic and hypereutrophic classes.
