Site-specific controls predominate over erosion effects on nitrogen turnover: Evidence from 15N tracing in the field

Understanding how nitrogen (N) cycling is affected by soil erosion is essential to optimize N supply for crops and reduce losses in hilly fields. While topography-related impacts on N availability and losses have been studied, the mechanisms linking erosion to N transformation dy...

Food Security Versus Environmental Health: The Nitrogen Dilemma

ABSTRACT Nitrogen is an essential element for plant growth and, consequently, crop production. However, the cycling of nitrogen in the environment can have negative effects. Here, we review the historical development of scientific and public awareness of these effects and the inf...
