The global increases in the surface and groundwater nitrate (NO3−) concentrations due to
synthetic fertilizer input have emerged as major sustainability threats to terrestrial and …

Vegetable production in greenhouses is often associated with the use of excessive amounts
of nitrogen (N) fertilizers, low NUE (15–35%), and high N losses along gaseous and …

Future rice systems must produce more grain while minimizing the negative environmental
impacts. A key question is how to orient agricultural research & development (R&D) …

Cover crops are well recognized as a tool to reduce NO3− leaching from agroecosystems.
However, their effectiveness varies from site to site and year to year depending on soil, cash …

Farmers, food supply-chain entities, and policymakers need a simple but robust indicator to
demonstrate progress toward reducing nitrogen pollution associated with food production …

Lake water pollution has caused many serious ecological issues globally. An emerging
public concern over water quality deterioration in lakes has heightened the need to evaluate …

Two of the most important agricultural practices aimed at improving soil properties are crop
rotations and no-tillage, yet relatively few studies have assessed their long-term impacts on …

Nitrogen fertilization is critical to optimize short-term crop yield, but its long-term effect on soil
organic C (SOC) is uncertain. Here, we clarify the impact of N fertilization on SOC in typical …

Agricultural intensification has led to a large increase in drained arable land and pastures
worldwide over the last two centuries. The installation of land drains not only affects the …

Animal manures are suspected to be a major source of nitrate leaching due to their low
nitrogen use efficiency (NUE) by crops. However, actual measurements of nitrate leaching …
