EzraAtmospheric 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.

What are different ways by which nitrogen in the air reaches the soil?
Nitrogen in the air can reach the soil through processes like atmospheric deposition (nitrogen compounds in rain and dust settling on the soil), nitrogen fixation by bacteria in the soil or by nitrogen-fixing plants, and through the decomposition of organic matter releasing nitrogen back into the soil.
What are two ways that nitrogen is fixed so plants can use it?
Nitrogen can be fixed by symbiotic bacteria in root nodules of leguminous plants, converting atmospheric nitrogen into ammonium ions. Nitrogen can also be fixed through lightning strikes, which initiate a reaction that converts atmospheric nitrogen into nitrogen oxides that can be absorbed by plants.
Two ways by which plants get nitrogen compounds?
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.
What are the different ways by which nitrogen in the air reaches the soil?
Nitrogen in the air can reach the soil through a process called nitrogen fixation, where certain bacteria convert atmospheric nitrogen into forms that plants can use. Additionally, nitrogen can also enter the soil through rainfall, where it gets dissolved and carried down into the soil profile. Industrial activities and agricultural practices can also contribute to nitrogen deposition in the soil through the release of nitrogen-containing compounds into the atmosphere.
What are the different ways by nitrogen in the air reaches the soil?
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.
