Irrigation and fertilizer application can lead to significant changes in groundwater quality. In
this study, a field irrigation experiment was carried out from April 9 to 23, 2021 under …

The spatiotemporal distribution of pore water in the vadose zone can have a critical control
on many processes in the near‐surface Earth, such as the onset of landslides, crop yield …

Excess nitrate (NO3–) loading in terrestrial and aquatic ecosystems can result in critical
environmental and health issues. NO3–-rich groundwater has been recorded in the …

Additional evidence indicates that the nitrate stored in the deep soil profile has an important
role in regulating the global nitrogen (N) cycle. This study assessed the effects of land-use …

Re-vegetation is a necessary control measure of soil erosion in the Loess Plateau. However,
excessive re-vegetation can aggravate soil water shortage, which can in turn threaten the …

Future agriculture calls for increased input (eg, water, nutrients, pesticides) use efficiency
while maintaining or improving productivity, minimizing environmental impacts, and …

Nitrate accumulation in the deep vadose zone poses direct or potential threat of environment
and agriculture due to the long hydraulic retention time, especially in areas with limited …

Soil water content (SWC) is critical for the health and sustainability of the ecosystem in water
limited areas. Characterized by low precipitation and deep groundwater, the Chinese Loess …

Due to severe soil erosion and low crop yield, slo** croplands have been converted into
forests and grasslands during the past decades on China's Loess Plateau (CLP). The …

Abstract Characterization of the rainfall infiltration mechanism, whether piston or preferential
flow, through an unsaturated zone is necessary for groundwater resource assessment and …
