How is nitrogen produced for fertilizer?
3 min read
Asked by: Matthew Law
Nitrogen. In a modern plant, nitrogen fertilizer is produced from natural gas. In several transformation steps, natural gas, essentially methane, is upgraded by combination with nitrogen from the air to form nitrogen fertilizer.
Who produces nitrogen for fertilizer?
The global production of nitrogen fertilizer amounted to some 117.5 million metric tons in 2018.
Production volume of nitrogen fertilizer worldwide in 2018, by country (in thousand metric tons)
| Characteristic | Production in thousand metric tons |
|---|---|
| China | 28,943 |
| United States | 13,617 |
| India | 13,337 |
| Russia | 9,430 |
Where is nitrogen fertilizer made?
Nitrogen Fertilizer Manufacturers in the U.S.
Most ammonia production in the U.S. occurs near large reserves of natural gas in Louisiana, Oklahoma, and Texas due to the use of natural gas as a hydrogen feedstock, and to fuel the high temperature and pressure needed to produce ammonia (Apodaca 2020a).
How is urea nitrogen fertilizer made?
Urea is manufactured synthetically by reacting natural gas, atmospheric nitrogen and water together at high temperature and pressure to produce ammonia and carbon dioxide. These gases are then reacted at high temperature and pressure to produce molten (liquid) urea.
How is nitrogen produced?
Industrial nitrogen gas is produced by cryogenic fractional distillation of liquefied air, separation of gaseous air by adsorption, or permeation through membranes. Cryogenic distillation of air is the oldest method of nitrogen production and was developed in 1895 (1).
How do you make nitrogen?
And compress it into some kind of a container that can hold it under pressure once it's under pressure we can pass it through a nitrogen membrane which will separate the oxygen.
Why are nitrogen based fertilizers bad?
Most plants cannot tolerate synthetic fertilisers or high levels of nitrogen. Nitrogen pollution causes nitrogen-tolerant species to thrive and outcompete more sensitive wild plants and fungi. This reduces wildlife diversity and damages plant health.
Does nitrogen come from natural gas?
Introduction. Nitrogen is one of the most common non-hydrocarbons in natural gas, whose physical properties are much like hydrocarbons rather than other non-hydrocarbons.

What is the main source of nitrogen?
The combustion of fossil fuels such as coal and oil is the major source of nitrogen in atmospheric deposition. Atmospheric deposition of nitrogen may be in a wet form as rain, snow, hail, fog, and freezing rain, or in a dry form as particulates, gases, and droplets.
How is nitrogen made naturally?
When an organism excretes waste or dies, the nitrogen in its tissues is in the form of organic nitrogen (e.g. amino acids, DNA). Various fungi and prokaryotes then decompose the tissue and release inorganic nitrogen back into the ecosystem as ammonia in the process known as ammonification.
How do you increase nitrogen in soil?
You can increase nitrogen in soil by adding nitrogen-rich fertilizer, composted manure, processed plant-based soil amendments, homemade compost, and even by planting certain crops that can pull nitrogen down into the soil from the atmosphere. These are all great sources of nitrogen for plants.
How plants get nitrogen from soil?
Plants cannot themselves obtain their nitrogen from the air but rely mainly on the supply of combined nitrogen in the form of ammonia, or nitrates, resulting from nitrogen fixation by free-living bacteria in the soil or bacteria living symbiotically in nodules on the roots of legumes.
