Nitrogen retention in rivers: Model development and application to watersheds in the northeastern USA

Anthropogenic nitrogen sources and relationships to riverine nitrogen export in the northeastern USA

Human activities have greatly altered the nitrogen (N) cycle, accelerating the rate of N fixation in landscapes and delivery of N to water bodies. To examine relationships between anthropogenic N inputs and riverine N export, we constructed budgets describing N inputs and losses for 16 catchments, which encompass a range of climatic variability and are major drainages to the coast of the North Atlantic Ocean along a latitudinal profile from Maine to Virginia.

Nitrogen budgets for the Republic of Korea and the Yellow Sea region

Growing populations in northeast Asia have greatly altered the nitrogencycle, with increases in agricultural production to feed the population, andwith increases in N emissions and transboundary air pollution. For example,during the 1900's over 50% of the N deposition over Republic of Korea wasimported from abroad. In this paper, we present biogeochemical budgets ofN for the South Korean peninsula (the Republic of Korea) and for the YellowSea region. We quantify N inputs from atmospheric deposition, fertilizers,biological fixation, and imports of food, feed, and products.
