प्रश्न
How does the application of cyanobacteria help improve agricultural output?
उत्तर
Cyanobacteria are free living or symbiotic blue green algae which are capable of converting atmospheric molecular nitrogen into soluble forms like nitrites or nitrates. They enrich the nitrogen content of the soil, thus, acting as a natural fertilizer. They replenish the soil with the nitrogenous compounds and hence are useful in agriculture.
