Abstract Groundwater 18O/16O, 2H/1H, 13C/12C, 3H, and 14C data can help quantify
molecular movements and chemical reactions governing groundwater recharge, quality …

More than two billion people and 40% of global agricultural production depend upon
unsustainable groundwater extraction. Managed aquifer recharge (MAR), the practice of …

Background Deep roots are a common trait among a wide range of plant species and
biomes, and are pivotal to the very existence of ecosystem services such as pedogenesis …

Many terrestrial surfaces, including soils, rocks and plants, are covered by photoautotrophic
communities, capable of synthesizing their own food from inorganic substances using …

Soil nitrate is important for crop growth, but it can also leach to groundwater causing nitrate
contamination, a threat to human health. Here, we report a significant accumulation of soil …

Over the past few decades, the La Paz aquifer system in Baja California Sur, Mexico, has
been under severe pressure due to overexploitation for urban water supply and agriculture; …

Intensive agriculture and urbanization have led to the excessive and repeated input of
nitrogen (N) into soil and further increased the amount of nitrate (NO 3−) leaching into …

Biological soil crusts (biocrusts) cover about 12% of the Earth's land masses, thereby
providing ecosystem services and affecting biogeochemical fluxes on a global scale. They …

Watershed and global-scale nitrogen (N) budgets indicate that the majority of 1 the N
surplus in anthropogenic landscapes does not reach the coastal oceans. While there 2 is …

The sustainability of groundwater usage faces quality problem caused by anthropogenic
activity as well as geogenic contamination. With varied climate zones, geomorphology and …
