Nitrification is a process of nitrogen compound oxidation (effectively, loss of electrons from the nitrogen atom to the oxygen atoms), and is catalyzed step-wise by a series of enzymes.

Nitrification is the biological conversion of reduced nitrogen (N) in the form of ammonia (NH3) or ammonium (NH 4+) or organic N to oxidized N in the form of nitrite (NO 2−) or nitrate (NO 3−).

Nitrification is one of the nitrogen cycle’s important processes. It is an essential process for soil health and fertility, food production, water treatment, and aquatic ecosystems.

Excess nitrogen in the form of ammonia in finished water can be the principal cause of nitrification since ammonia serves as the primary substrate in the nitrification process.

Aug 4, 2025 · Nitrification is the biological oxidation of ammonia into nitrite, which is then further oxidized into nitrate. It is a key component of the global nitrogen cycle, moving nitrogen through the …

Jul 24, 2025 · The nitrification process, from ammonium to nitrate, is fundamental not just within natural ecosystems but also across multiple human activities involving nitrogen management.

Feb 17, 2023 · Nitrification is an essential step in the nitrogen cycle of soil, water, and wastewater treatments. It involves the biological oxidation of ammonia (NH 3) or ammonium (NH 4+) to nitrite …

Many organisms live in the soil. Some of these are able to change ammonium nitrogen (NH 4+) to nitrate nitrogen (NO 3-). This process is called nitrification. Nitrification has two steps — both are carried out …

In a process called nitrification, or nitrogen fixation, bacteria such as Rhizobium living within nodules on the roots of peas, clover, and other legumes convert diatomic nitrogen gas to ammonia.

Oct 14, 2025 · Nitrification is an aerobic microbial process by which specialized bacteria oxidize ammonium to nitrite and then to nitrate. It is an essential part of the nitrogen cycle, affecting global …
