Does a dandelion root fix nitrogen?

Answer 1

Dandelion roots do not fix nitrogen. Nitrogen fixation is a process typically performed by certain bacteria that live in symbiosis with plant roots, particularly legumes. Dandelions, like many other non-leguminous plants, absorb nitrogen from the soil rather than converting atmospheric nitrogen into a usable form. However, dandelions can benefit soil health by improving its structure and providing organic matter when they decompose.
