Single nutrient ("straight") fertilizers

The main nitrogen-based straight fertilizer is ammonia (NH₃) ammonium (NH₄⁺) or its solutions, including:

• Ammonium nitrate (NH₄NO₃) with 34-35% nitrogen is also widely used.
• Urea (CO(NH₂)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.
• Calcium ammonium nitrate Is a blend of 20-30% limestone CaCO₃ or dolomite (Ca,Mg)CO₃ and 70-80% ammonium nitrate with 24-28  % nitrogen.
• Calcium nitrate with 15,5% nitrogen and 19% calcium, reportedly holding a small share of the nitrogen fertilizer market (4% in 2007).
