Help with making nutrients from scratch

I've been trying to find some good info on making some nutrients from scratch. Does anyone have any info or links to people doing it?

It's full time job...
Carbonized bones and powder cubbyhole for the phosphor, wood ashes which it is necessary to rinse several times to extract the potassium hydroxide from it and a six pack more one chicken...
The color we don't care but needs to pluck him because by decomposing feathers supply a powerful nitrogen.

Try permaculture on your browsner and why not Yacouba Sawadogo too on the way.

Edit: carbonized bones reduced on powder for the phosphor
