Write the importance of nitrogen-fixing bacteria in soil.
Answers
Answer:
Nitrogen-fixing bacteria are microorganisms present in the soil or in plant roots that change nitrogen gases from the atmosphere into solid nitrogen compounds that plants can use in the soil
Explanation:
ll organisms on Earth require nitrogen to survive, but most cannot use nitrogen unless it is combined with other elements. These compounds are formed by the process known as nitrogen fixation, which can only be carried out in nature with the help of microorganisms. In agriculture, fertilizers are often deployed to supplement nitrogen levels in poor soil.
Samples taken from Argentina (above) as well as certain Tunisian soils are allowing researchers to better understand nitrogen fixation

In an effort to improve our understanding of how microbial nitrogen fixation works, two research teams, including DOE Joint Genome Institute scientists, collected samples from Tunisia and Argentina. Their results were published in Genome Announcements in July 2013. In these studies, researchers assembled draft genome sequences of two members of the Frankia genus which are known to be nitrogen-fixing plant symbionts. Researchers are investigating how ammonia-based compounds from nitrogen fixation are produced.
Answer: Some plants/crops can't obtain nitrogen directly from the are even the nitrogen composition is the highest. So farmer uses nitrogen-fixing bacteria in the soil to obtain nitrogen directly from air.
