The main nitrogen-based straight fertilizer is ammonia (NH 3) ammonium (NH 4 +) or its solutions, including: Ammonium nitrate (NH 4 NO 3) with 34-35% nitrogen is also widely used. Urea (CO(NH 2) 2), with 45-46% nitrogen, another popular source of nitrogen, having the advantage that it is solid and non-explosive, unlike ammonia and ammonium nitrate.
However, the excessive or inefficient use of nitrogen fertilizers can lead to environmental problems such as nitrogen leaching, runoff, and emissions of nitrogen oxides (NOx). [4] Nitrogen leaching occurs when nitrogen compounds, primarily nitrates , move through the soil profile and enter groundwater, potentially contaminating drinking water ...
