Exploitation of groundwater has greatly increased since the 1970s to meet the increased
water demand due to fast economic development in China. Correspondingly, the regional …

Drip irrigation has been gradually adopted for winter wheat production in the North China
Plain (NCP) due to significant saving from using irrigation water and improving water and …

Assuring the quantity and quality of groundwater resources is essential for the well-being of
human and ecological health, society, and the economy. For the last few decades …

Abstract The North China Plain (NCP) has progressively implemented drip irrigation for
winter wheat (Triticum aestivum L.) production because of its substantial irrigation water …

Identification of different nitrate sources in groundwater is challenging in areas with diverse
land use and multiple potential inputs. An area with mixed land-uses, typical of the piedmont …

Inefficient irrigation practices have hindered crop yields, wasted irrigation water resources,
and posed threats to groundwater levels and agricultural sustainability. This study evaluated …

Although anthropogenic groundwater recharge (AGR) can either elevate or decline the
concentration of nitrate in the phreatic aquifer with high hydraulic conductivity, the long-term …

Identifying nitrate sources and their temporal evolution in different land use is important for
the sustainable management of groundwater resources. In this study, groundwater dating (3 …

Identifying the key factors controlling groundwater chemical evolution in mountain‐plain
transitional areas is crucial for the security of groundwater resources in both headwater …

The exogenous input of nitrate in groundwater may change microbial community, and in
turn, the change of microbial community affects the biogeochemical transformation of nitrate …
