I didn't read all the posts. Having worked on granddad's farm... I can say organic waste matter, be it animal or plant, is the best fertilizer. Better if you use it together. Gotta have some worms though... they eat that stuff and shit out good dirt. Now you gonna put hog shit or cow shit on your garden, you'd best wait a season before planting... granddad always waited two seasons.
Like I said... you gotta have some worms. He'd go down to the gardens that were "resting" whenever it rained and the worms come up, get a bunch of them and breed them in the compost pile. Then he would take them back down to the gardens and dig a hole and put them in it. Then spread the compost.
I'll give him this... man could grow some food. We never went hungry.
He grew some of the best strawberries. It was a good day indeed when you went to harvest the strawberries. Big ole things. Then he had the blackberry patch. Big ass ole bushes. Nothing better than blackberries and strawberries on your cornflakes in the morning.

Damn! Now I got a hankering for some blackberries and not a blackberry bush in sight.
