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 else can I help you with?
What is meant by fixed in nitrogen fixation?
Nitrogen Fixation is a process of combining atmospheric nitrogen with other elements to form useful compounds. Nitrogen is essential to living things, but most organisms cannot use nitrogen that is not combined with other elements. This is why nitrogen fixation is important to the continuation of life on earth.
What the processes involved in the nitrogen cycle?
plans take them both in and convert them both to a form we (and other animals) can use - sugars and proteins. decomposers are the type of bacteria that break dead things down - so convert the carbon in us to the CO2 form or into organic material in the soil and they also convert the nitrogen in living things into ammonium in the soil. the nitrogen fixing bacteria turn the nitrogen from the soil also into the ammonium. the ammonium is converted into nitrates by nitrifying bacteria which can be then used by plants and then we eat the plants...
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?
Six: hydrogen, carbon, oxygen, nitrogen, phosphorus and sulfur.
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?
Lightning cannot be prevented, it is an integral part of the functioning of the Earth and its balances of energy and electrostatic charges. The primary disadvantage of lightning is not just the potential to damage plants like trees, but also the risk associated with killing animals. Livestock that have been struck by lightning often die, which means a loss of income and productivity for the producer involved in sustainable agricultural practices. It is also not a reliable source of nitrogen fixation, because of the rarity and randomness of the strike pattern. A producer involved in sustainable agriculture must make use of legumes to provide a steady source of nitrogen fixation.
What are two major ways in which nitrogen is fixed in ecosystems?
Nitrogen can be fixed in ecosystems through biological processes, like by nitrogen-fixing bacteria that convert atmospheric nitrogen into a usable form for plants. It can also be fixed through human activities, such as the use of nitrogen fertilizers in agriculture.
