There seems to be a lot of conjecture around this subject. What should one use in a vegetable garden for fertilizer.

The common answer would be Manure, but some say your working against yourself since manure contains seeds, which makes sense.

I doubt a good peble lawn fertilizer is going to do much, wrong nutrients.

I was going to dump a bunch of peat into it this fall, and let it do it's stuff. I've got a lot of worms in this soil, so i figured the peat would feed them well. Problem is i just read that rotting peat lowers PH (raises acid), which cant be good.

whatever i do, i wanna do it in the fall so it's got the winter to distribute. I have access to a tiller to mix it up to about 10 inches deep.

So, what's the answer here?

I should probably note that i live in canada, so from about november to april the soil is 100% frozen.
