Most atmospheric nitrogen (N) exists as N2. Plants cannot use N in this form. The main ways this nitrogen enters soil in a plant usable form include:N fixation by bacteriaLightening caused atmospheric fixationFertilizer manufacturers also use atmospheric N when making N fertilizers.Most of the N is fixated by bacteria, usually in association with a plant. Legumes, like beans, peas and clover, are especially famous for this. The plants provide the bacteria with food and an environment they can live in, and in exchange, they give the plant usable nitrogen compounds.
The only forms of nitrogen compounds that living things can make use of are ammonia compounds and nitrate compounds.These are called "fixed nitrogen". Animals obtain the nitrogen they need from proteins in the plants and/or animals they eat. Proteins are amino acid polymers and amino acids are built around an ammonia group.
Plants obtain nitrogen compounds through the uptake of nitrate and ammonium ions from the soil through their root systems. Additionally, some plants have symbiotic relationships with nitrogen-fixing bacteria that convert atmospheric nitrogen into a form that can be used by the plants.
Lightning changes the nitrogen in the air into another form called nitrate.THE NITRATE IS BROUGHT DOWN TO THE SOIL BY RAIN.Nitrate is the only form of nitrogen that can be absorbed by plants through its roots.--hhahahah
Nitrogen in the air reaches the soil primarily through a process called nitrogen fixation, where certain bacteria convert atmospheric nitrogen into a form that plants can use. Nitrogen can also reach the soil through precipitation, as nitrogen compounds are washed out of the atmosphere and deposited onto the soil surface. Additionally, nitrogen can enter the soil through the decomposition of organic matter, releasing nitrogen back into the soil as plant nutrients.
Atmospheric nitrogen can enter the ground through nitrogen-fixing bacteria that convert atmospheric nitrogen into a form that plants can use. It can also be deposited into the ground through rainfall as nitric acid or ammonium ions.

Why does atmospheric nitrogen need to be converted?
Actually nitrogen exist in the atmosphere in dinitrogen (N2) form and cannot be utilized directly. As such bacteria help in converting atmospheric nitrogen into ammonia which then can be used by the plants.
Nitrogen can combine and form nitrates primarily through two processes: biological nitrification and atmospheric nitrogen fixation. In biological nitrification, soil bacteria convert ammonia (NH3) into nitrites (NO2-) and then into nitrates (NO3-) through a series of oxidation reactions. In atmospheric nitrogen fixation, lightning or certain bacteria convert atmospheric nitrogen (N2) into ammonia, which can subsequently be oxidized into nitrates by soil microorganisms.

Nitrogen is made available to plants through nitrogen fixation by certain bacteria that convert atmospheric nitrogen into a usable form, through decomposition of organic matter releasing nitrogen compounds, and through industrial fertilizer application.
Biological nitrogen fixation: Certain bacteria, like rhizobia, can convert inert atmospheric nitrogen into ammonium. Industrial nitrogen fixation: The Haber-Bosch process takes atmospheric nitrogen and hydrogen to produce ammonia for fertilizers. Lightning: Nitrogen fixation can also occur through lightning strikes, which provide the energy needed to convert nitrogen gas into reactive nitrogen compounds.
Plants get it from bacteria which live associated with their roots who take atmospheric nitrogen and fixate it (nitrogen cycle). Animals can only get it by ingesting organic compounds which contain nitrogen, such as plants and other animals which have eaten plants.
Nitrogen can be removed from the atmosphere through the process of nitrogen fixation, where certain bacteria convert atmospheric nitrogen into forms that plants can use. Nitrogen can also be removed through lightning strikes, which can combine nitrogen molecules with oxygen to form nitrogen oxides that are washed out of the atmosphere by rain.
