The diagram illustrates the sources and concentration levels of nitrogen in the groundwater of a coastal city, along with the natural processes involved in the nitrogen cycle. Nitrogen enters the groundwater system from several sources. On the land surface, nitrogen is introduced through coastal vegetation, domestic and market gardens, industrial activities, and waste disposal. Fertilizers […]
