Dried Dandelion root as a top dress?

Hey y’all, I’m almost halfway through flowering and bought some dried dandelion root. I was thinking of grinding it up and top dressing. I know it’s a very nutritious root, but just curious if it’s high in N. Usually root vegetables want P, so I figured it’d be higher in P than N, I associate leaves with higher N ratios.

what do y’all think?

Dandelions are high in potassium.
