We don't use and chemical fertilizers, just compost, well rotted horse manure and green manures. sometimes some chicken manure. But most of my compost is used for potting up plants and then a big scoop in the planting hole, mixed with peat, vermiculite, soil. (I actually use some of the clay soil to mix with the rest of the stuff. Can't add much though, just too heavy and sticky. I don't have enough to do all 40 rows as a top dressing, as much as I'd like to.
I actually meant "too much" as in, too much for my brain to absorb
