ABSTRACT
Eutrophication following exposure to high nutrient loading has been the key environmental problem in lakes and reservoirs world-wide for many decades. Phosphorus (P) is invariably considered the most critical nutrient for the ecological state of lakes as well as any restoration attempts, though recent studies suggest that nitrogen (N) is of higher importance than previously assumed (Moss et al. 2013). The consequences of eutrophication are increased biomass of phytoplankton, resulting in turbid water, blooms of (often toxic) cyanobacteria and loss of biodiversity.
