What are the biofertilizers examples?
Bacterial Biofertilizers: e.g. Rhizobium, Azospirilium, Azotobacter, Phosphobacteria. Fungal Biofertilizers: e.g. Mycorhiza. Algal Biofertilizers: e.g. Blue Green Algae (BGA) and Azolla. Actinimycetes Biofertilizer: e.g. Frankia.
What are biofertilizers give five example?
Fertilizers directly increase soil fertility by adding nutrients whereas Biofertilizers add nutrients through the natural processes of fixing atmospheric nitrogen, solubilizing Phosphorus, and stimulating plant growth through the synthesis of growth promoting substances. Examples are: Azospirillum, Rhizobium, etc.
Which are the main biofertilizers?
The main sources of biofertilizers are bacteria, fungi, and cynobacteria (blue-green algae). The most striking relationship that these have with plants is symbiosis, in which the partners derive benefits from each other.

What are biofertilizers Biology 12?
– Biofertilizers are those fertilizers that contain microbes which are used for promoting the growth of plants. This is done by increasing the supply of nutrients that are essential for the growth of plants. The microbes that are used in biofertilizers can be bacteria, some blue green algae and mycorrhizal fungi.
