Agricultural land is a major source of nitrogen fixation because of the cultivation of leguminous crops that have symbiotic relationships with nitrogen-fixing bacteria in their roots. These bacteria convert atmospheric nitrogen into a form that plants can use, thereby enriching the soil with nitrogen. Additionally, the use of fertilizers and manure in agriculture also contributes to nitrogen fixation in the soil.

What is meant by fixed in nitrogen fixation?
"Fixed" in nitrogen fixation refers to the process by which atmospheric nitrogen (N2) is converted into a form that can be utilized by plants and other organisms, such as ammonium (NH4+) or nitrate (NO3-). This conversion is often carried out by nitrogen-fixing bacteria in the soil or by industrial processes.
What the processes involved in the nitrogen cycle?
The nitrogen cycle involves several processes: nitrogen fixation (conversion of N2 gas into ammonia), nitrification (conversion of ammonia to nitrites and then nitrates), assimilation (plants and animals use nitrates and ammonium for growth), ammonification (conversion of organic nitrogen into ammonia), and denitrification (conversion of nitrates back into atmospheric nitrogen). These processes are crucial for recycling nitrogen in ecosystems and maintaining balance in nutrient availability.
What is the rank the four major elements of human body?
The four major elements which together make up 96% of our body mass are carbon, oxygen, nitrogen and hydrogen. The ranking is based on the mass of a 70kg adult: Oxygen - 64.5% of body mass / 43kg out of 70kg Carbon - 18% / 16kg Hydrogen - 10% / 7kg Nitrogen - 3% / 1.8kg
Which organisms are most critical in the nitrogen cycle?
Bacteria are most critical in the nitrogen cycle, specifically nitrifying bacteria that convert ammonia to nitrites and then nitrates, and denitrifying bacteria that convert nitrates back to nitrogen gas. These organisms play a crucial role in recycling nitrogen in the environment.
How many major elements make up living organism?
There are four major elements that make up living organisms: carbon, hydrogen, oxygen, and nitrogen. These elements are found in all biological molecules and are essential for life processes.
What are the major parts in the nitrogen cycle?
The major parts of the nitrogen cycle include nitrogen fixation (conversion of atmospheric nitrogen into forms usable by plants), nitrification (conversion of ammonium into nitrites and nitrates by bacteria), denitrification (conversion of nitrates back into atmospheric nitrogen), and assimilation (incorporation of nitrogen into plant and animal tissues).
Producing genetically-engineered major crops to carry out nitrogen fixation has been hampered because?
the bacteria do not function properly when they are introduced into the plants.

Why was agriculture not a major economic source in the Northeast?
the land was too rocky and the climate was to cold
What are the five major source of livelihood in the Philippines?
Fishing Farming Mining Forestry Agriculture
What plays a major role in the eutrophication of lakes?
Readily soluble nitrogen and fertilizers from human waste and agriculture play a major role in the eutrophication of lakes.
What material plays a major role in the eutrophication of lakes?
Readily soluble nitrogen and fertilizers from human waste and agriculture play a major role in the eutrophication of lakes.
What is the proccess called when you convert nitrogen gas into ammonia?
The process is called nitrogen fixation, where nitrogen gas (N2) is converted into ammonia (NH3) by certain bacteria, such as Rhizobium and Azotobacter, or by non-biological means using the Haber-Bosch process.
Outline the major steps in the nitrogyn cycle?
The nitrogen cycle involves several key steps: nitrogen fixation (conversion of atmospheric nitrogen into forms usable by plants), nitrification (conversion of ammonium to nitrite, and then nitrate by bacteria), assimilation (incorporation of nitrogen into plant and animal tissues), ammonification (conversion of organic nitrogen into ammonium), and denitrification (conversion of nitrate back into atmospheric nitrogen by bacteria). These processes help maintain a balance of nitrogen in ecosystems.

What are the disadvantages of lightning in sustainable agriculture?
One major disadvantage of lightning in sustainable agriculture is the potential for crop damage due to fires caused by lightning strikes. Lightning can also lead to soil erosion and nutrient loss, impacting soil health and crop productivity. Additionally, lightning strikes can pose safety risks to farm workers and livestock.
Which is not a major source of groundwater pollution?
Desalination plants are not a major source of groundwater pollution. Groundwater pollution is typically caused by activities such as industrial discharges, agriculture runoff, and leaks from underground storage tanks.
