Where does most of the nitrogen that the bacteria use come from?
The nitrogen is absorbed into the soil from the atmosphere.
Does soil contain nitrogen?
Yes, soil does contain nitrogen.
What plant family helps return nitrogen to the soil?
Legumes fix nitrogen in the soil.
How atmospheric nitrogen enters the soil?
Typically, atmospheric nitrogen gets into the soil by nitrogen-fixing bacteria that are symbiotic with such plants as clover, soybeans and alfalfa. Bacteria in the plant extract nitrogen from the air, and when the plants die, the nitrogen remains in the soil as the plant decays.
What converts nitrogen in the nitrogen cycle?
okay heres the nitrogen cycle nitrogen from atmosphere it taken in by 1)lightning( its energy causes nitrogen to react with oxygen n rain to the soil) 2)nitrogen- fixing bacteria in nodules ( plant roots which take it directly form the atmosphere ) NITROGEN FROM SOIL to organisms 1)nitrogen fixing bacteria in soil - breakdown of dead plants n animals releases nitrogen to the soil 2)fertilizers - which contain nitrogen compounds eg NPK OR natural fertilizers i,e dead plants n animals release nitrogen , animal urine and faeces release nitrogen as well to the soil 3)nitrogen fixing bacteria in nodules get nitrogen from its compounds in the soil 4)nitrifying bacteria - converts compounds of ammonia into nitrates .. for the plant nodules NITROGEN TO ATMOSPHERE 1) denitrifying bacteria in soil - changes nitrates to nitrogen gas and its released back to the atmosphere
Where does most of the nitrogen that the bacteria use come from?
The nitrogen is absorbed into the soil from the atmosphere.
Does soil contain nitrogen?
Yes, soil does contain nitrogen.
What elements required by plants come directly from the soil?
Nitrogen, Magnesium, Potassium and Iron
How can someone increase the nitrogen in the soil?
Lightning increases nitrogen in the soil
What does not increase the amount of nitrogen in the soil?
It doesn't. Harvesting removes soil nitrogen
Nitrogen in the soil is used by what?
nitrogen in the soil is used by both plants and animals.
What are the different ways by nitrogen in the air reaches the soil?
Nitrogen can enter the soil from plants such as legumes which fix nitrogen in their roots. Also dead plants and animals add nitrogen into the soil.
How nitrogen in soil is detected?
All soil contains nitrogen - it is a matter of how much. The relative amount of nitrogen in soil can be determined with as small soil sample and a reagent for nitrogen from a soil test kit (simple soil test kits are sold in every garden center). The results do not tell you the "amount" of nitrogen in the soil, only if there is enough for healthy plant growth, or if the amount of nitrogen is too poor for healthy plant growth
Changing nitrogen gas to nitrogen in the soil?
with a nitrogen tank
How does harvesting increase the amount of nitrogen in soil?
it doesn't, it only removes soil nitrogen
What is the transfer of nitrogen from air to soil to organism and back to air or soil?
nitrogen cycle.
What is the transfer of nitrogen from air to soil to organism and back to air and soil?
nitrogen cycle
