Urea Fertilizer CAS NO.57-13-6

Urea is the most widely used solid nitrogen fertilizer and is usually applied as granules, although it is sometimes mixed with ammonium nitrate and dissolved in water to form urea ammonium nitrate solution. When applied to soil, urea reacts with water to form ammonia, which makes the nitrogen within the fertilizer available to plants. Urea fertilizers deliver one of the highest amounts of nitrogen at 46 percent, with no phosphorus or potassium.
