Question

name the most common process by which nitrogen is made available to plants

Answer 1

The most common process by which nitrogen is made available to plants is NITROGEN FIXATION.

Nitrogen has to be converted into nitrates (NO-3) for the use of plants. This can be done by Nitrogen fixation.

Nitrogen is converted ínto nitrates by some nitrogen fixing bacteria such as azotobactor(occurs freely in soil) and Rhizobium( occurs in root nodules of leguminous plants such as pea,gram , bean e.t.c ) convert the atmospheric nitrogen into nitrates which are soluble in water.

Answer 2

Nitrogen is made available to the plants by the process called as Nitrogen Fixation.


Nitrogen is a crucially important component of all life forms, an important part of many cells and processes such as amino acids, proteins, and DNA.

In plants, it is needed to make chlorophyll which is used in photosynthesis to make their food.

Nitrogen in its gaseous form (N2) can’t be used by most living things. It has to be converted or ‘fixed’ to a more usable form through a process called fixation.

Nitrogen gas (N2) diffuses into the soil from the atmosphere and different species of bacteria convert this nitrogen to ammonium ions (NH4+) that can be easily used by plants.

Legumes like clover and lupins are often grown by farmers because they have nodules on their roots that contain nitrogen-fixing bacteria.
