Although effects of land use/cover on nutrient concentrations in aquaticsystems are well known, half or more of the variation in nutrient concentration remains unexplained by land use/cover alone. Hyd...
Assimilatory uptake rather than nitrification and denitrification determines nitrogen removal patterns in streams of varying land use

Agricultural and urban land use increase nitrogen (N) concentrations in streams, which can saturate biotic demand by plants, algae, and bacteria via assimilative uptake, and by nitrification and denit...
