Question

Name two ways that improve nitrogen fixation naturally

Answer 1

Answer:

Nitrogen fixation is a process by which nitrogen in the atmosphere is converted into ammonia.

Explanation:

Nitrogen fixation occurs naturally in the soil by nitrogen fixing bacteria.

Some nitrogen fixing bacteria ( Rhizobia ) have a symbiotic relationship with plants.

Non symbiotic nitrogen fixing by bacteria ( Azospirilum ) also occurs in cases like rice roots.

Prokaryotic micro organisms that can fix nitrogen are called diazotrophs.

All biological nitrogen fixation is done by the enzyme nitrogenase which contains a metallic component ( iron ,molybdenum and vanadium ) .

Nitrogen fixation also occurs naturally in the air by means of lightning.

Explanation:

Answer 2

Lightning and Growing nitrogen fixing micro organisms, nitrogen can be fixed naturally.

Explanation:

• Nitrogen is the important micro nutrient required by the plants for their growth and development.

• The reason is nitrogen is the main component in the aminoacid formation which in turn helps in the protein synthesis.

• Plants can't take up atmospheric nitrogen as such.
• The atmospheric nitrogen is converted into nitrogenous compounds and ammonia.

• The micro organinsms such as diazotrophs ( Azotobacter, and archaea) converts nitrogen into nitrogenous compounds and ammonia naturally.

• Lightning is the electrostatic discharge which occurs naturally converts nitrogen inair into  nitrogenous compounds and ammonia.
