Question

What do you mean by the term "industrial and biological nitrogen fixation"?

Answer 1

There are economic, environmental, and agronomic benefits from using BNF in cropping systems. All living things require nitrogen. It is a key element of amino acids, the building blocks of proteins.

There is a huge reservoir of N in the atmosphere. Approximately 80% of the air consists of nitrogen gas (N2), but plants cannot use atmospheric N directly to make protein.

Answer 2

Answer:

Biological nitrogen fixation means conversion of atmospheric nitrogen into useful nitrogenous compounds or nitrates by living organisms, which can be easily absorbed by plants. The bacteria present in the root nodules of leguminous plants like Rhizobium, as well as some blue-green algae, help in the fixation of atmospheric nitrogen.
