Nitrates in the soil can be returned to the atmosphere through a process called denitrification, where bacteria convert nitrates into nitrogen gas. This occurs in oxygen-deprived conditions, such as waterlogged soil or during decomposition processes. The nitrogen gas is then released back into the atmosphere.
The bacteria that can release nitrogen from nitrates and nitrites in the soil back to the atmosphere are called denitrifying bacteria.
Your answer is invalid, because the plants return the nitrogen back in to the air. I think what you're trying to ask is what forms of nitrogen is taken by the plants. The answer is nitrides, and nitrates. Nitrides are formed by decomposers in the soil and further nitrogen fixation causes nitrides into nitrates. You can notice this through their equation: nitrides (n3) nitrates (no3).
1. lightning makes nitrates from nitrogen and oxygen in the air. the nitrates then get washed into the soil by rain. 2. animal and plants decompose- depositing organic nitrogen into the soil
Harvesting crops removes the plant material that has taken up nitrates from the soil for growth. This reduces the overall amount of nitrates in the soil because the plants are no longer present to continue absorbing nitrates from the soil. Without the plants to utilize the nitrates, the levels decrease over time.
Nitrates are leached from the soil when excess water percolates through the soil, carrying the nitrates with it deeper into the ground or into water bodies. This process happens when there is heavy rainfall or over-irrigation, and can lead to groundwater contamination if not managed properly.
The bacteria that can release nitrogen from nitrates and nitrites in the soil back to the atmosphere are called denitrifying bacteria.
Denitrifying bacteria, such as Pseudomonas and Paracoccus species, carry out the process of denitrification, converting nitrates in the soil into free nitrogen gas. This process helps to return nitrogen gas back to the atmosphere, completing the nitrogen cycle.

Nitrogen compounds known as Nitrates found in the soil
nitrates!!
Denitrifiaction is the reduction of nitrates into gaseous nitrogen which escapes from soil into atmosphere.
When anaerobic bacteria break down nitrates, they can denitrify the nitrates and release nitrogen gas (N2) back into the atmosphere. This process is called denitrification and it helps return nitrogen to the atmosphere in its inert form.
Decomposition.
When organisms die, decomposers return nitrogen to the soil as ammonia. The ammonia may be taken up again by producers. Other soil bacteria convert nitrates into nitrogen gas in a process called denitrifrication. this process releases nitrogen into the atmosphere once again.
Nitrates can be changed back into nitrogen through a process called denitrification. This process is carried out by denitrifying bacteria in the soil, which convert nitrates into nitrogen gas under anaerobic conditions. This nitrogen gas is then released back into the atmosphere.

The nitrates in the soil in the beakers could increase during an investigation due to the breakdown of organic matter in the soil, the addition of nitrogen-containing fertilizers, or the release of nitrates from decomposing plant material. These factors can contribute to the accumulation of nitrates in the soil over time.
