Association with Nitrogen Fixing Cyanobacteria
Azolla is used as a biofertilizer because it has an association with nitrogen-fixing cyanobacteria. The cyanobacteria, specifically Anabaena azollae, live in specialized cavities in the Azolla's leaves. These cyanobacteria have the ability to fix atmospheric nitrogen into a form that can be used by plants, thereby enhancing the nitrogen content in the soil.
Benefits of Nitrogen Fixation
- Nitrogen fixation is crucial for plant growth as it is an essential nutrient required for the synthesis of proteins, chlorophyll, and nucleic acids.
- By fixing nitrogen, Azolla contributes to improving soil fertility and promoting crop productivity.
- This symbiotic relationship between Azolla and cyanobacteria helps in reducing the dependency on chemical fertilizers, thus promoting sustainable agricultural practices.
Fast Multiplication and Nutrient Content
- Azolla is known for its rapid growth rate, which allows it to cover water bodies quickly and efficiently.
- Besides its association with nitrogen-fixing cyanobacteria, Azolla also contains other nutrients like phosphorus, potassium, and micronutrients, making it a valuable biofertilizer for crops.
In conclusion, the association of Azolla with nitrogen-fixing cyanobacteria is the primary reason for its effectiveness as a biofertilizer. This symbiotic relationship helps in enhancing soil fertility, promoting sustainable agriculture, and reducing the reliance on chemical fertilizers.
