Is spyrogyra bio fertilizer

Spirogyra is a genus of green algae that can contribute to soil health and fertility, but it is not classified as a traditional biofertilizer. It can improve soil quality by enhancing nutrient availability and promoting microbial activity when decomposed. However, its use as a biofertilizer is not as common as that of other organisms, such as rhizobacteria or mycorrhizal fungi, which are specifically used in agricultural practices for enhancing plant growth.
