Denitrification often occurs in waterlogged or anaerobic soils.

Denitrification increases soil nitrate levels.

Nitrogen mineralization converts organic nitrogen into nitrate directly.

Excessive nitrate from fertilizers can lead to water pollution (eutrophication).

Most atmospheric nitrogen is readily usable by most crops.

Denitrification returns nitrogen to the atmosphere as N2 or N2O.

Nitrification is the microbial oxidation of ammonium first to nitrite (NO2-) and then to nitrate (NO3-).

Ammonia is produced during nitrification.

Plants fix atmospheric nitrogen directly in leaves.

The nitrogen cycle ends when nitrogen is fixed by bacteria.

Ammonification decomposes organic nitrogen to ammonium.

Lightning fixes N2 directly into nitrate without intermediary steps.

Plants uptake nitrate and ammonium for growth (assimilation).

Plants absorb nitrogen mainly in the form of nitrate (NO3-) or ammonium (NH4+).

Denitrification is the reduction of nitrate to nitrogen gas (N2) or nitrous oxide (N2O) under anaerobic conditions.

Nitrification is a two-step process converting ammonium to nitrite then nitrate.

Nitrogen fixation converts N2 gas into ammonia in soil or roots.

Denitrification releases oxygen into the soil.

Nitrogen fixation converts N2 to ammonia (NH3) or ammonium (NH4+).

Nitrogen cycle involves both biotic and abiotic processes.
