anyone use organic fertilizer for lawns?

I'm a landscaper and am fairly new to the game

I've recently stumbled upon the art of making compost teas using worm humus, bat guano, sea kelp, molasses, humic acid etc

works out pretty cheap and seems good (most / many of the guys on the cannabis forums who grow by hydroponics swear by this method)

has anyone tried this on lawns, or is it best to stick to chemical?
