Sowing a new lawn

John Kelleher asked 6 years ago
I am in the process of preping the ground for seeding, part of which includes drawing in top soil to raise the level by 4″. I just have a few questions- • should I add sand to the soil prior to seeding? • should I roll the topsoil prior to seeding (I would presume so to to avoid depressions due to foot traffic when seeding) • what fertilizer if any should I add in conjuction with the seed. I want to do this right, so all advice will be greatly appreciated, or link to suitable webpage.
