Nitrogen enters the soil through the application of nitrogen-rich fertilizers and through the decomposition of organic matter, such as plant residues and animal manure. Nitrogen-fixing bacteria in legume plant roots also play a role in transferring nitrogen from the atmosphere to the soil.

What is meant by nitrogen fixation state two ways in which nitrogen gas of the atmosphere can be fixed in nature to get nitrogen compound in the soil?
Nitrogen fixation is the process by which nitrogen gas in the atmosphere is converted into nitrogen compounds that plants can use. This can occur through biological nitrogen fixation, where certain bacteria convert nitrogen gas into ammonia, and through abiotic processes like lightning strikes, which convert nitrogen gas into nitrogen oxides that can be absorbed by rain and deposited in the soil.
What are the two ways that atmospheric nitrogen gets into the ground?
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.
How is nitrogen used in two ways?
double or tripple bonded, dynamite or cyanide
What are two substances that contain nitrogen?
Two substances that contain nitrogen are ammonia (NH3) and nitric acid (HNO3). Both of these substances are commonly used in various industrial and agricultural applications.
How does nitrogen in the air and the soil converted into nitrates?
Nitrogen gas in the air is converted into nitrates through a process called nitrogen fixation by specialized bacteria. In the soil, nitrates are produced through nitrification, a two-step process involving the conversion of ammonium to nitrites and then to nitrates by bacteria.
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.
3 Describe two ways in which nitrates can be replaced naturally in the soil?
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

This can occur through biological nitrogen fixation, where certain bacteria convert nitrogen gas into ammonia, and through abiotic processes like lightning strikes, which convert nitrogen gas into nitrogen oxides that can be absorbed by rain and deposited in the soil.
What are two ways plants may impact the nitrogen cycle?
Plants play a crucial role in the nitrogen cycle through processes like nitrogen uptake and nitrogen fixation. They absorb nitrogen compounds from the soil, which helps to incorporate nitrogen into the food web. Additionally, certain plants, such as legumes, can form symbiotic relationships with nitrogen-fixing bacteria, converting atmospheric nitrogen into a form that is usable by plants and enriching the soil. This enhances soil fertility and supports the growth of other plants, contributing to a balanced ecosystem.
What are the two ways that atmospheric nitrogen gets into the ground?
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.
What are two ways by which nitrogen can combine and form nitrates?
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.
What are two ways nitrogen from the air changed into usable nitrogen?
lightning & bacterial action (nitrogen fixers).
What are the two ways nitrogen can be fixed?
Nitrogen can be fixed by lightning during thunderstorms, a process that converts nitrogen gas (N2) into nitrates (NO3-) that can be used by plants. Nitrogen can also be fixed by certain soil bacteria called nitrogen-fixing bacteria, which convert N2 into a form that can be taken up by plants.
How do farmers replace nitrogen in the soil?
There are two ways plants put nitrogen into the soil one is decomposition where a plant dies then decomposes putting the nitrogen back into the soil that it once took out. The other is from the air, Legumes are plants that take nitrogen from the air with their leaves and release it into the soil with its roots.
What are two ways of adding nitrogen to the soil without the use of artificial fertilizers?
Blood meal or fall time cover crop such as clover
What are the two most aboundant elements on Earth?
Nitrogen 78 % Silica in soil
How is nitrogen used in two ways?
double or tripple bonded, dynamite or cyanide
