Theoretical materials and tasks in Science CBSE, Class 8. Class 8, Science, Chapter-2, Lecture-5, Nitrogen Cycle (Notes) Soil Fertility and Microorganisms Symbiotic bacteria (Rhizobium) in the root nodules of leguminous plants absorb atmospheric nitrogen and convert it into nitrogenous compounds. Blue-green algae also fixes the atmospheric nitrogen as nitrogen compounds in the soil, enriching the soil and thus increasing its fertility. These microorganisms are commonly known as biological nitrogen fixers. NITROGEN CYCLE: A constant interaction in ... We would like to show you a description here but the site won’t allow us.
