What are different ways by which nitrogen in the air reaches the soil?
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.
Name the microorganisms which can fix atmospheric nitrogen in the soil?
Examples of microorganisms that can fix atmospheric nitrogen in the soil include certain species of bacteria such as Rhizobium and Azotobacter. These bacteria have the ability to convert atmospheric nitrogen into a form that plants can utilize, ultimately promoting plant growth and soil fertility.
Where does the nitrogen from the atmosphere go before enters a plant?
The nitrogen goes into the nodules of the plant.
How does atmospheric nitrogen enter the soil?
Atmospheric nitrogen can enter the soil through a process called nitrogen fixation, where certain bacteria convert nitrogen gas from the air into a form that plants can use. This can occur naturally through biological processes or through human activities such as the use of nitrogen-based fertilizers.
2 ways atmospheric nitrogen gets into the ground?
Atmospheric nitrogen can enter the ground through nitrogen-fixing bacteria in the soil that convert nitrogen gas into a form plants can use. It can also enter the ground through rainfall, where nitrogen oxides from the atmosphere dissolve in water and are deposited on the soil.
How atmospheric nitrogen enters the soil?
Typically, atmospheric nitrogen gets into the soil by nitrogen-fixing bacteria that are symbiotic with such plants as clover, soybeans and alfalfa. Bacteria in the plant extract nitrogen from the air, and when the plants die, the nitrogen remains in the soil as the plant decays.

Where does nitrogen from the atmosphere go before it enters?
Nitrogen from the atmosphere primarily enters the soil through a process called nitrogen fixation, where certain bacteria convert atmospheric nitrogen (N₂) into ammonia (NH₃) or related compounds. This process occurs in the root nodules of specific plants, like legumes, or in the soil by free-living bacteria. Once in the soil, nitrogen can be taken up by plants or further transformed by other soil microorganisms through processes like nitrification and denitrification. Ultimately, nitrogen becomes part of the food chain as it is absorbed by plants, which are then consumed by animals.
Can nitrogen be directly used by living things?
No, nitrogen gas cannot be directly used by most living organisms. Instead, nitrogen-fixing bacteria in the soil or in plant roots convert atmospheric nitrogen into a form (ammonia or nitrates) that can be used by plants to make proteins. Other organisms then obtain nitrogen by consuming these plants.
How does nitrogen enter a food web?
Nitrogen enters a food web through the process of nitrogen fixation, where certain bacteria convert atmospheric nitrogen into a form that plants can absorb. Plants then take up this nitrogen through their roots, and it is passed through the food web as animals consume plants and other animals. When organisms die and decompose, nitrogen is released back into the soil for plants to utilize again.
Where does nitrogen go before it enters a plant?
Before nitrogen enters a plant, it typically first undergoes a process called nitrogen fixation, where atmospheric nitrogen (N₂) is converted into ammonia (NH₃) by certain bacteria in the soil or in symbiotic relationships with legumes. This ammonia can then be transformed into nitrates (NO₃⁻) through nitrification, a process carried out by nitrifying bacteria. The resulting nitrates and ammonium ions are taken up by plant roots from the soil, allowing plants to utilize nitrogen for growth and development.
Name the microorganisms which can fix atmospheric nitrogen in the soil?
Examples of microorganisms that can fix atmospheric nitrogen in the soil include certain species of bacteria such as Rhizobium and Azotobacter. These bacteria have the ability to convert atmospheric nitrogen into a form that plants can utilize, ultimately promoting plant growth and soil fertility.
Why farmers prefer to grow bean and peas in nitrogen deficent soil?
They are capable of converting atmospheric nitrogen into nitrogen that can be used by plants. They make the soil better.
Where does the nitrogen from the atmosphere go before enters a plant?
The nitrogen goes into the nodules of the plant.
What are 3 things that remove nitrogen directly from the atmosphere?
Three processes that remove nitrogen directly from the atmosphere include nitrogen fixation, where certain bacteria and legumes convert atmospheric nitrogen (N₂) into ammonia (NH₃); lightning, which causes nitrogen gas to react with oxygen, forming nitrogen oxides that can eventually be deposited in the soil; and industrial processes, such as the Haber-Bosch process, which synthesizes ammonia from atmospheric nitrogen for fertilizers. These processes play crucial roles in the nitrogen cycle, making nitrogen available for biological use.
Does rain water contain nitrogen?
