Question

Some microbes act as very good biofertiliser. Explain with the help of three suitable examples

Answer 1

Explanation:

Rhizobia have the capacity to fix nitrogen (N2) from the atmosphere. These bacteria live either freely in the soil or in beneficial association with leguminous plants, including important crops such as peas, beans and soybeans.

The symbiosis is a fine-tuned interaction where the rhizobia convert atmospheric nitrogen into ammonia inside special structures known as root nodules.
