DOI: 10.1016/j.catena.2017.11.012
Abstract: Abstract The unsaturated zone is a significant feature of the nitrogen cycle in arid areas connecting atmospheric precipitation and surface water to groundwater. To measure NO3−, Cl−, and NH4+ concentrations, precipitation samples (39.9592°N, 94.3302°E) were… read more here.
