Biofertilizers are living organisms that enhance the nutrient content of the soil. They primarily derive from bacteria, fungi, and cyanobacteria. Additionally, there are other types of bacteria, such as Azospirillum and Azotobacter, capable of fixing atmospheric nitrogen even when existing independently in the soil.
Cyanobacteria, also known as blue-green algae, are autotrophic microorganisms found in various aquatic and terrestrial environments. Many cyanobacteria species, such as Anabaena, Nostoc, and Oscillatoria, possess the remarkable ability to fix atmospheric nitrogen. |
