Mainly to construct proteins, plants with high protein content are those which require the most.
Plants need nitrogen to fully mature and produce an abundance of foliage.
Plants use nitrogen a N- and air has N2. Nitrogen fixation changes nitrogen into a form that plants can use.
Because it converts nitrogen into a form plants can use.
Plants need nitrogen to grow. They are surrounded by nitrogen in the air, but it is not in a form the plants can use. Nitrogen fixing bacteria on the roots of the plant convert (fix) the airborne nitrogen to a form the plants can use to grow.
For protien
Plants use nitrogen in the form of nitrates. Nitrogen is essential in a healthy soil because plants use it in the form of an important nutrient.
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.
Many compounds in plants include Nitrogen including Proteins and DNA. Note, most plants can not use atmospheric Nitrogen (N2), and must absorb nitrogen that is bonded to hydrogen or carbon such as Ammonia (NH3).
nitrogen fixation
Grass and plants use nitrogen to grow.
It allows plants to use nitrogen to grow.
No. Plants cannot use elemental nitrogen. The nitrogen must first be fixed, either by lightning or by nitrogen-fixing bacteria. Some plants have such bacteria in their roots.
Nitrogen fixing bacteria along and on the roots of plants converts gaseous nitrogen into a form that plants can absorb.
