Sediment fractions of both potassium and phosphorus remained relatively high regardless of sediment nitrogen fertility or macrophyte species grown Total plant tissue nitrogen content was an order of magnitude higher in plants grown on fertilized sediment with Potamogeton consistently having a higher tissue nitrogen content than Hydrilla...

Nutrients such as nitrogen and phosphorus are important 313 Trends of Nutrient and Sediment Retention in Great Plains Reservoirs We understand that nutrient accumulation can occur due to surrounding environment algae requires more nitrogen for growth...

Biological mainly algal uptake of inorganic nitrogen species and further sedimentation of dead biomass together with its subsequent mineralization is one of the major mechanisms controlling in-pond nitrogen recycling in maturation WSP particularly when environmental and operational conditions are favourable for algal growth...

We focused primarily on nitrogen uptake via plant growth as well as sediment accretion on the FTW structure itself Due to funding limitations we were unable to include an assessment of the microbial catabolism of inorganic nitrogen species by any biofilms that may have developed The FTW was...

Eutrophication from Greek eutrophos well-nourished or hypertrophication is when a body of water becomes overly enriched with minerals and nutrients that induce excessive growth of plants and algae This process may result in oxygen depletion of the water body One example is the bloom or great increase of phytoplankton in a water body as a response to increased levels of nutrients...
