Papers

1. NONPOINT POLLUTION OF SURFACE WATERS WITH PHOSPHORUS AND NITROGENEcological Applications · 1998 · 5,897 citations

   Agriculture and urban activities are major sources of phosphorus and nitrogen to aquatic ecosystems. Atmospheric deposition further contributes as a source of N. These nonpoint inputs of nutrients are difficult to measure and regulate because they derive from activities dispersed…

2. HUMAN ALTERATION OF THE GLOBAL NITROGEN CYCLE: SOURCES AND CONSEQUENCESEcological Applications · 1997 · 5,463 citations

   Nitrogen is a key element controlling the species composition, diversity, dynamics, and functioning of many terrestrial, freshwater, and marine ecosystems. Many of the original plant species living in these ecosystems are adapted to, and function optimally in, soils and solutions…

3. The Nitrogen CascadeBioScience · 2003 · 2,956 citations

   Human production of food and energy is the dominant continental process that breaks the triple bond in molecular nitrogen (N 2 ) and creates reactive nitrogen (Nr) species.Circulation of anthropogenic Nr in Earth's atmosphere, hydrosphere, and biosphere has a wide…
