Increasing incidences of eutrophication and groundwater quality impairment from
agricultural nitrogen pollution are threatening humans and ecosystem health. Minimal …

Despite widespread implementation of watershed nitrogen reduction programs across the
globe, nitrogen levels in many surface waters remain high. Watershed legacy nitrogen …

Clarifying the biogeochemical mechanism of nitrate (NO 3−) in the vadose zone-
groundwater system, particularly in agricultural contexts, is crucial for mitigating groundwater …

Nitrogen (N) fertilizer applications are important for agricultural yield, yet not all the applied
N is taken up by crops, leading to surplus N storage in soil or leaching to groundwater and …

Worldwide surface waters suffer from the presence of nitrogen (N) compounds causing
eutrophication and deterioration of the water quality. Despite many Europe-wide …

Due to the complexity of nitrate sources and transformation processes under extensive
human activities and climate change, there are a great number of uncertainties associated …

Integrated water resources management (IWRM) has been central to water governance and
management worldwide since the 1990s. Recognizing the significance of an integrated …

Human agriculture, wastewater, and use of fossil fuels have saturated ecosystems with
nitrogen and phosphorus, threatening biodiversity and human water security at a global …

Understanding the fates of nitrogen (N) fertilizers applied to soil at the different scales is
crucial to increase N use efficiency and reduce N loss to the environment. However, most of …

Excess nutrient inputs from agricultural and urban sources have accelerated eutrophication
