I currently have about 6k foot back yard with Dandilyons, 2 decaying stumps and lots of bumps and lumps in it
 on the one side we have Lilacs that our aunt gave us a few years ago and the big decaying stump on the opposite side is a decaying stump that has a big hole in the middle.
 I have been using the hole for my lawn clippings for the past 3 or so years.
 we do have Mushrooms growing in the lawn as well as lots and lots of dandelions.
 I have been using a weed hound to remove the dandilyons as well as using about 10 ml's of vinegar on each one
 some times befor I remove as well as in the hole after i take them out
 I did find that the Mass university? did soil testing for under $15.00
 when the results came back, I sent a copy to my local Master Gardener annex
 The recommended that i use Lilly Miller for the NPK ratio. It has been great for the grass. On the other hand we still have the weeds and mushrooms
 I do have a 4yo that plays in the back yard.
 I do have pictures that I can share as well as pictures of grass/root/dirt that I can send as well.
 I do not want to dig up or add dirt at this time. just trying to get ideas on how to remove the dandelions as well as make the grass healthy Kid/pet/ and planet safe.
 thank you
