When there is not enough nitrogen in the atmosphere for plants how do the plants get it?
Plants do not actually get their nitrogen from the atmosphere. They get it in compounds in the soil through their roots. Some plants form symbiotic relationships with bacteria in the soil. The bacteria draw nitrogen from the air and form nitrogen compounds. The plants can then use the nitrogen.
What happens to the nitrogen compounds that are not absorb by the plants?
A number microbes in the soil, water and air transform these nitrogen compounds
Why do farmers grow leguminous crops between 2 other plants?
They have nodules on their roots which contain nitrogen fixing bacteria. These take the nitrogen from the air and convert it to nitrogen compounds in the soil which plants use as nutrients. In short, using leguminous plants increases the fertility of the soil.
Why is nitrogenous fertilizer not added in soil in which leguminous plants are grown?
Because leguminous plants are capable of fixing free nitrogen from the air with help of their root nodules. Thus soil get rich in nitrates in those places where these plants are grown.
How do the plants root absorb nitrates?
when the nitrogen in air is absorbed in the clouds and rains the nitrogen comes down to the soil with the water. this is absorbed by the roots .
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
Which organism fix nitrogen in the soil?
bacteria rhizobium fixes atmospheric nitrogen into air which plants can breathe.
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.
Where can nitrogen be found besides the air?
in soil
What is the difference between free nitrogen and fixed nitrogen?
Free nitrogen is in the air but fixed nitrogen is in the soil.
Where does plants get nitrogen?
when animals eat plants,they get nitrogen compounds that their bodies need.plants do not make these nitrogen compounds. so from where do plants get their nitrogen compounds/ from the air
The nitrogen cycle may be described as nitrogen moving from the air to the soil where plant roots use it as food. when plants die nitrogen is returned to the air true or false?
false, when the plant dies in this case, nitrogen is returned to the soil
Which nitrogen in the air reaches the soil?
Are you on about the Nitrogen cycle? If this is the case, Nitrogen can be transferred into the soil from animal deification, or Nitrogen ions can be transferred through a lightening storm and rain drops.
What are two substances that contain nitrogen?
Air and soil.
Process in which nitrogen is released into the air and soil?
Denitrification
What is the most common gas in soil air?
nitrogen
