[Temporal and spatial variation of non-point source nitrogen in surface water in urban agricultural region of Shanghai].

Urban Farm DB summary

A study in Orchard Village, Nanhui District, Shanghai, China, continuously monitored total nitrogen and inorganic nitrogen species in surface water to understand temporal and spatial variations. Findings showed that nitrogen spatial distribution is influenced by hydrological periods and land use, with nitrate nitrogen high in orchard-affected water during wet seasons and dissolved organic nitrogen being the main species in May.
