Difference between nitrogen fixation and nitrification

Main difference

The main difference between nitrogen fixation and nitrogen is that nitrogen fixation refers to the process of alteration of nitrogen-containing compounds in nitrogen gas, whereas nitrification is an alteration of ammonium ions to nitrites and nitrates. .

Nitrogen fixation vs. nitrification

Nitrogen fixation refers to the process of alteration of nitrogen gas in nitrogen-containing compounds, while nitrification refers to the process of alteration of ammonium ions into nitrates and nitrites. Nitrogen fixation occurs by passing through the different industrial, biological or atmospheric, while nitrification occurs with the help of nitrifying bacteria and soil bacteria. Nitrogen fixation occurs as the first step during the nitrogen cycle, while nitrification occurs as the second step during the nitrogen cycle. Nitrogen fixation is the essential process in which nitrogen gas is renewed into ammonium ions , while nitrification is the process in which ammonium ions are renewed into nitrites and nitrates. Nitrogen fixation is the chemical process while nitrification is the biological process. Nitrogen fixation can occur through biological, atmospheric, and industrial, while nitrification can occur only with the help of nitrifying bacteria. Nitrogen fixation is not the oxidation process while nitrification is the oxidation process. The living microorganism that participates in nitrogen fixation is called nitrogen fixers, while the living microorganism participates in nitrification is called nitrifying bacteria. . Nitrogen fixation is an essential process for nitrification, whereas nitrification is not the essential process for nitrogen fixation. The living microorganism that participates in nitrogen fixation is called nitrogen fixers, while the living microorganism that participates in nitrification is called nitrifying bacteria. Nitrogen fixation is an essential process for nitrification, while nitrification is not the essential process for nitrogen fixation.

What is nitrogen fixation?

Nitrogen fixation refers to the process of alteration of nitrogen gas into nitrogen-containing compounds. It is the process that occurs through biological, atmospheric and industrial processes. Nitrogen fixation is the first step in the nitrogen cycle. It is the step that is essential for nitrification. Its end products are ammonia or ammonium ions. It is the chemical process. Organisms that participate in nitrogen fixation are called nitrogen fixers. Nitrogen fixers can be symbionts or free-living. Nitrogen fixation is not an oxidation process. Nitrogen fixation is the first and essential process of the nitrogen cycle in which atmospheric nitrogen gas is transformed into nitrogen-containing compounds, which are also accessible to plants. Animals and humans do not have a special mechanism for nitrogen fixation. Also, almost 80% of nitrogen is present in the atmosphere, but plants and animals cannot take it in directly, so they use nitrogen fixation as part of the nitrogen cycle. It is essential for life on earth.

Nitrogen fixation processes
  • Biological process: the nitrogen cycle is the best example of nitrogen fixation.
  • Industrial process : The Haber process is the example of nitrogen fixation in industry.
  • Atmospheric process: Lightning is the process of nitrogen fixation in the atmosphere.

Microbes

Some aerobic bacteria are Azatobacter, Pseudomonas, Alcaligenes, Nostoc, etc.

What is nitrification?

Nitrification refers to the process that occurs with the help of nitrifying bacteria and that live in the soil. Nitrification is the second important step in the nitrogen cycle. It is also an essential step in the nitrogen cycle. Its final products are nitrites and nitrates. It is the biological process. Organisms that participate in nitrification are called nitrifying bacteria. Nitrification is the oxidation step. Nitrification is the essential process of the nitrogen cycle that converts ammonia or ammonium ions into compounds accessible to plants. Bacteria usually carry out nitrification. It is the oxidation process of ammonia. Enzymes are also involved in nitrification. They participate in the conversion of ammonium ions into nitrites and nitrates. Soil-dwelling bacteria participate in nitrification. Nitrification is a vital and important process in plant nutrition. This process is carried out on aerated soil. Nitrification always comes after nitrogen fixation. Nitrification is the main atmospheric nitrogen capture process for plants and animals.

Microbes

Nitrosomonas and Nitrobacter, etc.

Key differences

  1. Nitrogen fixation refers to the process of alteration of nitrogen gas in nitrogen-containing compounds, while nitrification refers to the process of alteration of ammonium ions into nitrates and nitrites.
  2. Nitrogen fixation is the chemical process; on the other hand, nitrification is the biological process.
  3. Nitrogen fixation occurs through biological, industrial and atmospheric processes, conversely nitrification occurs with the help of nitrifying bacteria in the soil.
  4. Nitrogen fixation is not an oxidation process, while nitrification is the oxidation process.
  5. Nitrogen fixation is the first important step in the nitrogen cycle; on the other hand, nitrification is the second step of the nitrogen cycle.
  6. Nitrogen fixation has end products like ammonia or ammonium ions, while nitrification has end products like nitrites or nitrates.
  7. The microorganisms involved in nitrogen fixation are called nitrogen fixers, while the microorganisms involved in nitrification are called nitrifying bacteria.
Final Thought

The above discussion concludes that nitrogen fixation and nitrification are both essential processes of the nitrogen cycle. Nitrogen fixation is the first important process in the nitrogen cycle in which atmospheric nitrogen is converted to ammonia or ammonium ions, while nitrification is the second important process in the nitrogen cycle in which ammonia and ammonia are converted. ammonium ion in nitrites and nitrates.
