Urea, N-P-K composition 46-0-0, is the most commonly produced and widely traded nitrogen product. It is estimated that 90 percent is used as fertilizer and the rest for industrial purposes. Synthesized from ammonia and carbon dioxide (CO2), urea is the only primary nitrogen product chemically classified as organic (because of its carbon content). Nitrogen is the most crucial and major nutrient element in plant growth. It is abundant in nature and enhances better yields. Because urea is produced from ammonia and carbon dioxide, which is a by-product of ammonia production, all urea plants are located adjacent to or in proximity to an ammonia plant.
China and India account for more than a half of urea output (as well as capacity), however, these two countries are the largest urea consumers, over half of it. In 2013, 44 percent of the urea fertilizer was consumed in East Asia, followed by South Asia, which took nearly a quarter of the product.
