Black dirt is what you want to add to your lawn when adding new grass seed. Do not use top soil. It has weeds in it, and it will dry up and choke the new new grass. After reseeding your lawn each year, you need to be patient, as your work will not be rewarded right away. This is like anything in life: mastering an instrument, building a professional relationship with a university or starting up a website. Your progress can be excruciatingly slow. If you have had good advice and are on the right track, you must be patient and persistent. It is the only thing that will ensure a thick lawn or a successful career.
