“Compost tea” can also be used to add beneficial bacteria to the soil. It’s just water that has been allowed to steep in compost. The exact recipes vary, with some only running the water thru the compost once, then spreading.

Years ago, I purchased along with legume seed, a package of "nitrogen fixing bacteria" designed for peas and beans.
Usage was easy: place a little water in a zip-lock bag, add seeds, add 1/4 teaspoon of the black bacteria, and shake for seed coverage.
Any residual in the bag would be used to inoculate any additional legume seed as only used a light dusting on the seed
I had the best crop of Sugar Snap and Oregon Edible Pods, ever, thanks to the innoculant (nitrogen fixing bacteria).
I haven't seen bacteria innoculant, though, in recent years.
