What process effectively makes nitrogen unavailable for plant use?

The reduction of nitrate to gaseous nitrogen. Most plants cannot use atmospheric(gaseous) nitrogen. It must be "fixed" by bacteria in the ground. Plants use nitrogen in the forms of ammonia(NH4+) and nitrate ions(NO3-).

What is the source of energy that makes this process possible?
nitrogen in the atmosphere and the ground
Why is nitrogen unavailable to plant in acidic soil?
[1] The 16-17 nutrients in healthy soil must be in soluble form in order to be taken up by plant roots. [2] Generally, nitrogen isn't a problem. It tends to be abundant above and below ground. So it's unavailability tends to be more linked with drought conditions above and below ground. Less moisture below ground makes for less of the available nitrogen accessible to plants, which can only take in soluble nutrients. [3] Calcium and magnesium are more likely to become unavailable in acidic soil.
Why activation energy for Haber process is high?
The triple bond between the nitrogen atoms in nitrogen gas is very strong.it takes nearly a megajoule of energy to break apart one mole of nitrogen gas, This makes nitrogen very nearly inert at normal temperatures and pressures.
What process by bacteria by which removes nitrogen from the air and makes it available to plants?
Bacteria performs nitrogen fixation, which involves converting the atmospheric nitrogen (N2) into usable organic nitrates (NO3-). Said bacteria are often referred to as nitrogen fixating bacteria. The process is sometimes called nitrification.Scientists have been able to give plants genes from bacteria to help them do a beeter job. This process is called recombinant DNA technology. Nitrogen fixing bacteria are in root nodules on legumes and maybe some other plant groups.Converts nitrogen in the air to nitrates.
Does cellulose contain nitrogen?
yes - all things made by photosynthesis is based on nitrogen and carbon. The energy differential between these is how energy from the sun is consumed and makes plants absorb carbon dioxide, and need nitrogen (i.e. fertilizer and air) to support this process.
What is the most abundant gas in our atomopshere?
In the Earth's Atmosphere; Nitrogen, this makes up about 78% of the Air we breathe.
Which makes up more of the atmosphere Nitrogen or Oxygen?
Nitrogen
What makes up 20 percent of the earths atmosphere?
balls
What is a good jingle to sell nitrogen?
~nitrogen~it makes bombs explode~nitrogen~it puts you in the mode
What makes a flame?
Nitrogen
Why nitrogen is included in mineral but it is not mineral?
Minerals are formed from different elements. Nitrogen, (which is a gas in its natural state) makes up 78% of earths atmosphere. Minerals are formed through a biogeochemical process, generally forming crystals.
Is nitrogen air?
Nitrogen makes up about ~80% of the air we breath in.
