I'm going to weigh in pretty heavily in a couple of days with a couple of organic turf care FAQs that I'm developing for y'all. They will cover the basics of what all works, why they work, and when/how to use them. They will be suitable for downloading to keep as a reference. Due to space limitations on Lawnsite, I'll have to make several different FAQs, so if you don't see it in one, look in the other(s).
These FAQs will be works in progress. If I say anything really stupid, they are subject to revision. But for beginners, they will answer a lot of questions y'all have.
