Information @ a Glance

  • Nitrogen is a chemical element which has the symbol N and atomic number 7. Elemental nitrogen is a colorless, odorless, tasteless and mostly inert diatomic gas at standard conditions, constituting 78.1% by volume of Earth's atmosphere. Nitrogen is a constituent element of all living tissues and amino acids. Many industrially important compounds, such as ammonia, nitric acid, and cyanides, contain nitrogen.
  • Nitrogen was discovered by the Scottish physician Daniel Rutherford in 1772. It is the fifth most abundant element in the universe and makes up about 78% of the earth's atmosphere, which contains an estimated 4,000 trillion tons of the gas. Nitrogen is obtained from liquefied air through a process known as fractional distillation.
  • Nitrogen (N) is an essential element of life and a part of all plant and animal proteins. Crop plants cultivated for human consumption and a animal feed require nitrogen for proper nutrition and maturation.
  • Liquid nitrogen is inert, colorless, odorless, non-corrosive, nonflammable, and extremely cold. Nitrogen makes up the major portion of the atmosphere (78.03% by volume, 75.5% by weight). Nitrogen is inert and will not support combustion; however, it is not life supporting. Nitrogen is inert except when heated to very high temperatures where it combines with some of the more active metals, such as lithium and magnesium, to form nitrides.
  • The largest use of nitrogen is for the production of ammonia (NH3). Large amounts of nitrogen are combined with hydrogen to produce ammonia in a method known as the Haber process. Large amounts of ammonia are then used to create fertilizers, explosives and, through a process known as the Ostwald process, nitric acid (HNO3).
  • Ammonia is the basic building block for producing nearly all forms of nitrogen-based fertilizers. To a lesser extent, it is also used directly as a commercial fertilizer. Ammonia is produced by reacting gaseous nitrogen with hydrogen at high pressure and temperature in the presence of a catalyst.
  • Nitrogen, the plant nutrient and fertilizer component most widely applied by American farmers, is essential for maintaining the high yields achieved for major crops such as corn, wheat, and cotton in this country. Natural gas is a key component in the production of nitrogen, and the cost of natural gas can account for up to 90 percent of nitrogen fertilizer production costs.
  • Namhae in South Korea has announced that it will be closing its plant. This may mean an annual import of over 400,000 mt by the company to continue to supply its distribution network. Omnia in South Africa has purchased 15,000 mt Libyan urea through Keytrade at $124 per mt cfr bulk for mid-November arrival. Omnia has also purchased some granular urea from Bangladesh and Saudi Arabia.
  • The Urea market, outside of North America, is bucking the bullish trend seen in other Nitrogen commodities with prices for AN, UAN and ammonia all escalating. The Yuzhny-US Gulf cfr granular spread is now a massive $90pt with the Arab Gulf trading at a $30pt premium on prills. The United States remained the world’s second largest producer and consumer of elemental and fixed types of nitrogen following China.
  • North American nitrogen margins and sales volumes increased compared to both the third quarter of 2006 and the fourth quarter of 2005, on stronger North American demand and lower natural gas prices. Higher ammonia volumes moved from our Borger system. North American nitrogen sales volumes were 35 percent higher in the fourth quarter of 2006 than for the same period last year.
  • Nitrogen market fundamentals remain positive due to the expectation of strong import demand from regions such as India, North America, Europe, and Latin America. Higher grain prices and an increase in corn and wheat acreage should support nitrogen demand globally. On the supply side, higher domestic operating rates have only partially offset a significant year over year decline in nitrogen imports.
