Explore how specific microbes such as Rhizobium, Azospirillum, mycorrhiza, and cyanobacteria improve soil health and support plant growth as natural biofertilizers.
Nostoc, a cyanobacterium, fixes atmospheric nitrogen, enriching soil fertility in paddy fields.
Ref: NCERT Class 12 Biology Chapter 8: Microbes in Human Welfare Microbes as Biofertilizers - Rhizobium Azospirillum Mycorrhiza Cyanobacteria
Azospirillum is a free-living nitrogen-fixing bacterium that improves soil fertility in rice fields.
Ref: NCERT Class 12 Biology Chapter 8: Microbes in Human Welfare Microbes as Biofertilizers - Rhizobium Azospirillum Mycorrhiza Cyanobacteria
Cyanobacteria like Nostoc and Anabaena are free-living nitrogen-fixing organisms that enhance soil fertility.

Rhizobium is a symbiotic nitrogen-fixing bacterium found in root nodules of leguminous plants.
Ref: NCERT Class 12 Biology Chapter 8: Microbes in Human Welfare Microbes as Biofertilizers - Rhizobium Azospirillum Mycorrhiza Cyanobacteria
Biofertilizers are cost-effective, sustainable, and improve soil fertility without harming the environment.
Ref: NCERT Class 12 Biology Chapter 8: Microbes in Human Welfare Microbes as Biofertilizers - Rhizobium Azospirillum Mycorrhiza Cyanobacteria
Rhizobium forms symbiotic relationships with leguminous plants and helps in nitrogen fixation.
Ref: NCERT Class 12 Biology Chapter 8: Microbes in Human Welfare Microbes as Biofertilizers - Rhizobium Azospirillum Mycorrhiza Cyanobacteria
Rhizobium forms root nodules in legumes and fixes atmospheric nitrogen, improving soil fertility.
