Consumption of Nitrogen fertilizers in EU 15
Philippe Rekacewicz, UNEP/GRID-Arendal
The graph shows Consumption of Nitrogen fertilizers in EU 15 from 1970 to 1992. The main source of nitrogen in soils is from organic matter. Nitrogen also comes from sources such as factories. A common concern with these forms of inorganic nitrogen is the incremental amount of nitrates they add to the nitrogen cycle, which may threaten groundwater, inland waters and fisheries.
