Experimental evidence that pollution with urea can degrade water quality in phosphorus-rich lakes of the Northern Great Plains
pollution urea degrade water quality phosphorus-rich lakes the Northern Great Plains
2014/4/17
Urea is the most abundant nitrogen (N) fertilizer used on agricultural soils, yet its effects on adjacent aquatic ecosystems are largely unknown. Here 21-d, 3000-liter mesocosm experiments were conduc...
Regulation of spatial and temporal variability of carbon flux in six hard-water lakes of the northern Great Plains
Regulation of spatial temporal variability carbon flux six hard-water lakes northern Great Plains
